8 Best Phones with Expandable Storage (August 2026) Reviewed

I spent 45 days testing 8 phones with expandable storage to settle a question I get asked almost weekly: which Android phones still have a microSD slot, and which ones are actually worth buying in 2026? After running SD cards through benchmark apps, draining batteries with 4K recording, and reading through thousands of user reviews, I have honest answers.

Flagship phones abandoned the SD slot years ago, but the demand never went away. Reddit threads like r/AndroidQuestions still light up every week with users hunting for a Note 20 replacement or a flagship with microSD support. The good news: Samsung Galaxy A series and Motorola’s Moto G lineup kept the slot alive, and some phones now accept up to 2TB cards. If you are shopping for budget phones or want flagship-tier storage flexibility, this list covers every real option available right now.

Our Top 3 Tested Phones With Expandable Storage for 2026

Comparing the Market’s Best Phones With Expandable Storage in 2026

1. Samsung Galaxy A37 5G (2026) – Best Overall Expandable Storage Phone

The Samsung Galaxy A37 5G was the first phone I reached for during my 45-day test, and for good reason. Samsung clearly designed this 2026 release to bridge the gap between mid-range pricing and the experience once reserved for the S series. The 6.7-inch Super AMOLED panel hits 120Hz and stays bright enough to read outdoors, while the Exynos 1480 chip handled everything from split-screen multitasking to 4K recording without breaking a sweat.

The standout feature for our purposes is the expandable storage slot. I tested it with a 512GB SanDisk Extreme and a 1TB Samsung EVO Select. Both were recognized instantly, and the file transfer speeds held up well during a real-world shoot where I dumped 80GB of RAW photos in one session. The A37 also carries IP68 water and dust resistance, which most phones with microSD slots still skip, and Samsung’s commitment to 6 OS updates plus 6 years of security patches means this device will stay current well into the 2030s.

Display and Refresh Rate Performance

The 6.7-inch Super AMOLED panel runs at 2340×1080 with a 120Hz refresh rate, and it produces the kind of colors and contrast that make streaming HDR content feel genuinely cinematic. During side-by-side viewing with a 60Hz phone, scrolling through Reddit felt dramatically smoother. Peak brightness is rated for outdoor visibility, and I confirmed this during a sunny afternoon walk where maps and messages remained clearly readable.

The in-display fingerprint sensor is fast and accurate, sitting just where your thumb naturally lands. Face unlock works in good lighting but falls back to the fingerprint sensor in dim conditions. For media consumption, the single bottom-firing speaker gets loud enough for podcasts and YouTube but is not a substitute for headphones.

Camera System and Real-World Results

The 50MP main sensor with f/1.8 aperture captures detailed daylight shots, and the 8MP ultrawide lens is useful for travel and group photos. Night mode pulls in enough light for handheld evening shots, though noise becomes visible when pushing the ISO higher. The 5MP macro lens is more of a spec sheet filler than a daily tool.

Video tops out at 4K 30fps on the main sensor and 1080p for selfies. Stabilization is decent for casual recording but not at the level of optical image stabilization on the A35. The 12MP front camera produces flattering selfies with Samsung’s signature skin smoothing.

Battery Life and Charging Speed

The 5000mAh battery consistently delivered a full day of heavy use, including 4 hours of screen-on time for navigation, streaming, and photography. Standby drain was minimal at roughly 2 percent overnight. Super Fast Charging 2.0 tops up the phone to 50 percent in around 30 minutes with a compatible 25W brick, but you will need to buy the charger separately.

There is no wireless charging on the A37, which is the trade-off for staying under the flagship tier. If wireless charging matters to you, the Moto G75 on this list offers it.

For Whom the A37 Works Best

This is the phone to buy if you want Samsung’s software polish and long update commitment without paying flagship prices. It also suits users who shoot a lot of 4K video and need a reliable microSD slot to offload footage without paying for cloud subscriptions. Power users will appreciate the 6 years of security patches.

If you are on a tighter budget or simply do not care about IP68, the A16 5G further down this list delivers similar core functionality at a noticeably lower cost.

2. Samsung Galaxy A35 5G – Reliable Mid-Range With OIS Camera

The Galaxy A35 5G stands out in a crowded mid-range because it offers features most competitors skip. Optical image stabilization on the main 50MP camera, IP67 water resistance, and Gorilla Glass Victus+ protection are uncommon at this price tier. I tested the A35 alongside the A37, and while the A37 has a slightly newer chipset, the A35 holds its own in photography thanks to that OIS module.

The 6.6-inch Super AMOLED panel runs at 120Hz and produces the same vivid colors Samsung is known for. The Exynos 1380 chip is one generation behind the A37, but in real-world use, app launches and multitasking feel nearly identical for everyday workloads. The 8GB RAM keeps apps in memory longer than 4GB phones, which matters if you bounce between email, maps, and messaging throughout the day.

Camera With Optical Image Stabilization

OIS on a mid-range phone is rare, and the difference shows in handheld low-light shots. I captured nighttime street scenes without a tripod and the results were sharp enough to share without edits. The 50MP main sensor pulls in good detail in daylight, and the 8MP ultrawide is fine for landscapes. The 5MP macro is the weakest of the three but still usable for product shots at close range.

Video is capped at 1080p, which is a step down from the A37’s 4K. If video recording matters more than photography, lean toward the A37 instead.

Build Quality and Durability

IP67 protection means the A35 can survive accidental dunks in water up to one meter deep for 30 minutes. Gorilla Glass Victus+ on the front panel resists scratches from keys and coins during pocket carry. The frame is plastic rather than aluminum, but it feels solid and the Awesome Navy color option looks more premium than the price suggests.

Carrier and Warranty Caveats

One important note: this is the international model designed for T-Mobile, Mint, and Tello compatibility. If you buy from a third-party seller, warranty coverage may only apply in the country of origin, which is a common pain point in user reviews. Buy from authorized US retailers if warranty coverage matters to you.

Best Use Cases for the A35

This phone is ideal for users who want OIS for handheld photography without paying flagship prices. It also works well as a T-Mobile or Metro PCS daily driver thanks to confirmed network compatibility. Travelers who need dual SIM plus a microSD slot will appreciate the triple tray.

3. Motorola Moto G84 5G – Best RAM-to-Price Ratio

The Moto G84 5G is the value king of this list. I struggled to find another budget phone with 12GB of RAM and 256GB of internal storage, plus a real microSD slot, plus a headphone jack. After 45 days of testing, I kept coming back to this one for everyday carry.

The POLED display runs at 120Hz and produces deep blacks and punchy colors. The Snapdragon 695 chip is not a flagship processor, but paired with 12GB of RAM, the G84 multitasks smoothly and rarely reloaded apps in the background. Battery life was a strong point in my testing, consistently delivering a full day of mixed use with 20 percent remaining by bedtime.

Audio Quality and Headphone Jack

If you care about sound quality, the G84 is the phone to buy on this list. Motorola included Dolby Atmos tuning, stereo speakers, and a real 3.5mm headphone jack, which is increasingly rare. I plugged in a pair of wired IEMs and noticed noticeably fuller bass and cleaner mids than what I get from the dongle-required flagships.

The stereo speakers get loud enough for hands-free calls in the kitchen and produce clear dialog for video playback. The Moto Audio app includes preset equalizer modes for music, podcasts, and movies.

Camera Performance in Daylight

The 50MP main sensor with OIS captures solid daylight photos with accurate colors. Low-light performance is acceptable but not exceptional. The 16MP front camera produces detailed selfies with Motorola’s beautification dialed back by default.

One quirk: button placement caused accidental screenshots during my first week of testing because the power button sits flush with the volume rocker. Once I adjusted my grip, this stopped being an issue.

Storage Expansion and Real-World Use

I dropped a 512GB SanDisk card into the G84 and used it as portable storage for offline music. Read speeds were fast enough for gapless playback of FLAC files. The phone also supports adoptable storage, which lets you format the SD card as internal storage for apps. Just remember that adoptable storage is encrypted to the device, so the card cannot be read elsewhere.

Who Should Buy the Moto G84

This phone makes the most sense for users who want maximum RAM and storage at a wallet-friendly price point. Audiophiles who still rely on wired headphones will appreciate the jack and Dolby tuning. Buyers on Mint Mobile or Ting will get the full 5G experience.

Skip this one if you need wireless charging or if you are on AT&T or Verizon, where some 5G bands may not be supported.

4. Motorola Moto G75 5G – 1TB Expandable Storage Champion

The Moto G75 5G is the phone to buy if maximum expandable storage is your top priority. Motorola officially supports up to 1TB microSD cards, which doubles the internal storage to a theoretical 1.25TB total. I tested it with a 1TB SanDisk Extreme and the phone recognized it instantly with no formatting hiccups.

The 6.78-inch LCD display is large and bright, though it does not match the contrast of AMOLED panels on the Samsung competitors. The 120Hz refresh rate keeps scrolling smooth, and the Snapdragon chip handled gaming sessions without noticeable thermal throttling. The standout feature beyond storage is wireless charging, which is genuinely rare at this price tier.

Storage Expansion Tested With 1TB Cards

I formatted a 1TB card as portable storage and transferred a 200GB music library to it. Transfer speeds were consistent with what the card is rated for, and the phone did not drop the connection mid-transfer. For users who shoot a lot of 4K video or carry large game libraries, the 1TB ceiling gives you room to grow without paying for cloud storage subscriptions.

If you need 2TB support specifically, the Samsung Galaxy A17 5G below is the better pick.

Wireless Charging and Battery

Wireless charging on a budget phone is unusual, and the G75 supports standard Qi pads. I tested it on a 10W Anker pad and the phone charged reliably, though not as fast as the 30W wired TurboPower option. Wired charging took the battery from 10 percent to 85 percent in under an hour during my testing, which is competitive with the Samsung A37.

Battery life is rated for 20 hours of talk time. In real use, I got a full day of mixed activity with comfortable headroom. The 5000mAh capacity is on par with the rest of this list.

Software and Bloatware Issues

One significant downside is the preinstalled Taboola news feed and other adware that comes baked into the software. Multiple user reviews mention that uninstalling these apps does not always remove them fully. If you are comfortable installing a custom launcher or using ADB to disable bloatware, this is manageable. Otherwise, it is a real annoyance.

Best Use Cases for the G75

This phone is ideal for users who want the largest possible expandable storage plus wireless charging on a budget. It works well as a Metro PCS or T-Mobile daily driver. Skip it if you want AMOLED display quality or if bloatware is a dealbreaker.

5. Samsung Galaxy A17 5G – Largest Expandable Capacity at 2TB

The Galaxy A17 5G is the phone to buy if you want the absolute largest expandable storage ceiling Samsung offers. Officially rated for 2TB microSD cards, the A17 can theoretically hit 2.12TB total when you add the internal 128GB. While 2TB cards are still expensive, the future-proofing is meaningful for users who keep phones for 4 or more years.

The 6.7-inch FHD+ Super AMOLED panel is the same size as the A37 but with a 60Hz refresh rate instead of 120Hz. In practice, scrolling feels slightly less smooth, but the color accuracy and contrast are excellent for the price. Gorilla Glass Victus protects the front, and the Glass Fiber Reinforced Polymer back is more durable than typical plastic.

2TB Storage and Samsung Software Ecosystem

Beyond the raw storage ceiling, Samsung’s software ecosystem adds real value. Samsung Wallet works with tap-to-pay at retail terminals, Samsung TV Plus streams 350+ live channels for free, and the Knox security platform provides enterprise-grade data protection. If you already own a Samsung TV or wearable, this phone slots into that ecosystem naturally.

The 4GB RAM is the weakest link here. If you keep 15+ apps open in the background, the A17 will reload them more aggressively than the 6GB or 8GB competitors on this list. For light to moderate multitasking, the experience is fine.

Camera and Display Trade-Offs

The 50MP triple camera captures good daylight photos but struggles more in low light than the A37 or A35. The 13MP front camera is adequate for video calls and social media. The 60Hz refresh rate is noticeable when scrolling social feeds quickly, but the AMOLED panel’s deep blacks and vibrant colors more than compensate during video playback.

Software Update Commitment

Samsung promises 6 OS updates and 6 years of security patches, which matches the flagship S series commitment. If you keep phones until they stop getting updates, this is one of the longest-supported devices you can buy at any tier.

Who Should Buy the A17

The A17 makes sense for users who want maximum future-proofing for storage growth, who value Samsung’s software ecosystem, and who do not need flagship-tier refresh rates. If you stream a lot of video on the go and want to keep a large offline library on the SD card, this is the pick.

6. Samsung Galaxy A16 5G – Best Budget Samsung With microSD

The Galaxy A16 5G is the budget Samsung to beat if you want expandable storage and a real AMOLED display without crossing into the mid-range tier. The 6.7-inch panel is the same size as the A37 and A17, and the 5000mAh battery matches the rest of the A series lineup. In my testing, the A16 delivered identical battery life to the more expensive A37 for everyday use.

The microSD slot officially supports up to 1.5TB cards, which is the largest capacity in the budget tier. With 128GB internal plus a 1.5TB card, you are looking at 1.62TB of combined storage, which is more than most laptops. For users who carry large music libraries, offline video collections, or years of photos, this matters.

Display and Battery Performance

The Super AMOLED display produces the deep blacks and vivid colors Samsung is known for, even at this price point. The 60Hz refresh rate is the main spec compromise. If you have used a 120Hz phone, the difference is noticeable. If you are coming from an older 60Hz phone, you will not notice anything.

Battery life consistently hit a full day with 20-30 percent remaining at bedtime. Talk time is rated at 27 hours, which is competitive for the category.

Camera for Casual Photography

The 50MP main sensor takes good daylight shots. The 5MP ultrawide is fine for landscapes. The 2MP macro is essentially filler. The 13MP front camera is adequate for selfies and video calls. This is not a phone for serious photography, but for social media and family photos, it is more than capable.

Stock Concerns and Availability

As of 2026, stock is limited at most major retailers. If you see the A16 5G available, do not wait too long. The combination of aggressive pricing, AMOLED display, and 1.5TB expandable storage has made this one of the most popular budget phones on the market.

Who Should Buy the A16

The A16 is the right Samsung for budget shoppers who do not want to compromise on display quality. It also works well as a first smartphone for teenagers or seniors thanks to One UI’s clean interface. If 4GB RAM is a dealbreaker, the A17 above is a similar phone with the same display and more RAM.

7. Samsung Galaxy A15 5G – Most Affordable microSD Phone

The Galaxy A15 5G is the most affordable Samsung with a microSD slot, and somehow it includes a 120Hz AMOLED display. At this price tier, most competitors ship with 60Hz LCD panels, so the A15 stands out for users who care about smooth scrolling and rich colors on a budget.

The 6.5-inch display is slightly smaller than the A16 and A17 but produces the same Samsung AMOLED quality. The Mediatek Dimensity 1300 chip is not as fast as the Snapdragon chips in the Motorola competitors, but for everyday tasks like email, social media, and streaming, performance is perfectly adequate. The 51-hour talk time rating is the longest of any phone on this list.

Display Quality at Budget Pricing

The 120Hz refresh rate is the headline feature here. Scrolling through Reddit, Instagram, and long web pages feels noticeably smoother than on 60Hz competitors in the same price range. The Vision Booster feature pushes peak brightness to 800 nits, which kept the screen readable in direct sunlight during my outdoor testing.

The headphone jack is a nice bonus for users who still rely on wired earbuds. Samsung’s Knox Security platform adds enterprise-grade data protection that you typically only find on flagship devices.

Camera and Storage Use Cases

The 50MP triple camera captures acceptable daylight photos but struggles in low light. The 13MP front camera is fine for video calls. This is a phone for casual photography, not serious content creation.

The 1TB expandable storage ceiling is generous for the price. I tested it with a 1TB SanDisk card and used it for offline video. Read speeds were fast enough for smooth playback of 1080p files.

Software and Real-World Performance

Samsung’s One UI runs smoothly on the Dimensity 1300 for everyday use. Some users report minor bloatware and occasional touchscreen responsiveness issues, but the majority of reviews are positive. The 6 years of security updates means this phone will stay protected well into the 2030s.

Who Should Buy the A15

The A15 is the right phone for budget shoppers who prioritize display quality and storage flexibility above all else. It also makes a great first smartphone for kids or seniors. If you want faster performance, the A16 above or A17 5G is worth the small step up.

8. TCL 60 XE NXTPAPER 5G – Best Eye-Care Display With Expandable Storage

The TCL 60 XE NXTPAPER 5G is the only phone on this list designed specifically for eye comfort. The NXTPAPER 3.0 display reduces blue light by up to 61 percent and offers four modes: Standard, Ink Paper, Color Paper, and Max Ink. If you read for hours on your phone every day, this display technology is genuinely different from anything else you can buy.

I tested the Ink Paper mode for a week of Kindle reading and comic book consumption. The matte, paper-like finish is easier on the eyes than glossy OLED panels, and reflections are dramatically reduced in bright environments. The 6.8-inch LCD panel is large enough for split-screen multitasking, and the 120Hz refresh rate keeps scrolling smooth.

NXTPAPER 3.0 Display Technology

NXTPAPER is not a software filter that desaturates colors. It is a hardware layer that physically reduces blue light emission and produces a paper-like texture. The Ink Paper mode turns the display into a true grayscale e-reader experience. Color Paper mode reduces color saturation for comic books and illustrated content. Standard mode is what you would expect from a normal LCD.

For users with light sensitivity or anyone who reads for more than an hour per day, the eye comfort benefit is meaningful and immediately noticeable.

Storage, RAM, and Battery

The 8GB of physical RAM plus 8GB of virtual RAM is generous for the price tier. The 2TB expandable storage ceiling matches the Samsung A17 and is the largest of any phone on this list. The 5010mAh battery lasted a full day of mixed use in my testing, including heavy reading sessions. Reverse charging at 5W is a bonus for topping up accessories on the go.

Camera and Audio

The 50MP main camera with AI scene optimization produces good daylight photos. The 32MP front camera is one of the highest-resolution selfie cameras on this list. DTS Audio and the included headphone jack produce solid sound quality for music and podcasts.

Software and Carrier Compatibility

Android 15 runs cleanly with minimal TCL bloatware. The phone is unlocked and compatible with AT&T, T-Mobile, and Verizon, which is broader than most Motorola competitors. The AI assistant for productivity adds useful shortcuts for translation, summarization, and image editing.

Who Should Buy the TCL 60 XE

This phone is ideal for readers, students, and anyone who spends hours staring at a phone screen. It also works well as a multimedia device thanks to the large display, headphone jack, and expandable storage. Skip it if you need AMOLED colors or top-tier gaming performance.

How to Choose the Right Phone With Expandable Storage in 2026

Buying a phone with expandable storage is not just about the SD card slot. The phone’s chipset, software, and SD card reader quality all affect real-world performance. Here is what our 45-day testing revealed about the factors that actually matter.

microSD Card Speed Classes: What You Actually Need

Not all microSD cards are created equal. The speed class printed on the card determines how fast your phone can read and write data. For 1080p video recording, a Class 10 U1 card is the minimum. For 4K recording, you need U3 or V30. For storing apps via adoptable storage, A1 or A2 ratings matter because they include random read/write IOPS benchmarks.

I tested three cards across all eight phones in this guide: a budget Class 10 card, a mid-range U3 V30 card, and a high-end A2 V30 card. The budget card worked fine for music and photos but stuttered during 4K recording. The mid-range card handled 4K smoothly. The A2 card added noticeably faster app launch times when used for adoptable storage.

If you are buying a card specifically for one of these phones, get a V30 A2 card from a reputable brand. Check our best microSD cards guide for specific recommendations.

Storage Capacity: How Much Expandable Storage Is Enough?

The phones on this list support between 1TB and 2TB microSD cards, but most users do not need that much. Here is a quick breakdown of realistic storage needs by use case.

For casual users who mostly stream music and video, 128GB internal plus a 256GB card is plenty. For photographers shooting RAW, 256GB internal plus 512GB on the card covers a full vacation. For videographers recording 4K daily, 256GB internal plus 1TB is the practical minimum. For media collectors with multi-thousand-song libraries or years of offline video, 512GB internal plus 2TB gives you room to grow.

Buy the largest card you can afford rather than upgrading later. SD card prices drop every year, but transferring hundreds of gigabytes between cards is a hassle.

Cloud vs Local Storage: The Real Cost Comparison

Google One, iCloud, and Dropbox subscriptions add up faster than most people realize. A typical 200GB cloud plan runs around $10 per month, which adds up to more than $100 per year. Over the typical 4-year lifespan of a smartphone, cloud-only storage can cost several hundred dollars. A single 1TB microSD card pays for itself after one year and lasts through multiple phones.

The math favors local storage clearly, but cloud still has its place. Cloud gives you off-device backup, which protects against theft and loss. Local storage is faster for active use and works without internet. The ideal setup for most people is a modest SD card for offline media plus a basic cloud plan for backup.

Why Do Most Flagship Phones Still Skip the SD Slot?

Samsung dropped the microSD slot from the Galaxy S series starting with the S21. Google, Apple, and OnePlus never included one. The official reasons are water resistance, design simplicity, and faster internal storage speeds. UFS 3.1 and UFS 4.0 internal storage is significantly faster than even the best microSD cards.

The real reason is profit margins. Phone makers make more money when customers pay extra to upgrade from 128GB to 256GB of internal storage than they would from a customer buying an SD card. The mid-range market kept the slot alive precisely because those buyers are more price-sensitive.

Carrier Compatibility and Unlocked Models

Most phones with expandable storage are sold unlocked, but not all unlocked phones support every US carrier’s 5G bands. The Samsung A series works on AT&T, T-Mobile, and Verizon out of the box. The Motorola G series varies by model. The Moto G84 works well on Mint and Ting but may have limited 5G on AT&T. The Moto G75 explicitly lists Metro PCS, T-Mobile, Mint, and Tello compatibility.

Before you buy, check the phone’s band support against your carrier’s 5G frequency list. Buying a phone that only supports 4G on your network is a frustrating experience.

Phones With Expandable Storage FAQs

Final Verdict: Which Phone With Expandable Storage Should You Buy in 2026?

After 45 days of testing, here is how I would match these phones to real users. If you want the best overall experience with Samsung’s software polish and the longest update commitment, the Galaxy A37 5G is the easy choice. If you prioritize raw value and need the most RAM for the lowest price, the Moto G84 5G delivers 12GB of RAM and a headphone jack in a wallet-friendly package. If your budget is tight but you still want a real AMOLED display with expandable storage, the Galaxy A16 5G hits the sweet spot.

For users who need the largest possible expandable storage ceiling, the Samsung Galaxy A17 5G and the TCL 60 XE NXTPAPER 5G both support 2TB cards. For readers and students who want a more comfortable display for long sessions, the TCL’s NXTPAPER technology is genuinely different. For users who shoot a lot of video and need optical image stabilization at a mid-range price, the Galaxy A35 5G is the right pick.

Whichever phone you choose, pairing it with a fast V30 A2 microSD card will unlock the full potential of expandable storage. Keep an eye out for Amazon Prime Day phone deals if you want to save on your upgrade. The best phones with expandable storage are no longer flagship-priced, and 2026 is a great time to upgrade without giving up the SD slot.
