Why the Android tablet is slow and how to fix it: a complete guide 2026

Did your tablet suddenly start to “stutter”, applications take 10 seconds to open, and video constantly freezes? This is a common problem faced by owners of devices from Android suddenly began to “stutter”, applications open for 10 seconds, and the video YouTube Does it freeze constantly? This is a common problem faced by device owners from Samsung Galaxy Tab to budget models Xiaomi Pad or Lenovo Tab. The reasons for the brakes can lie both in software failures and in “hardware” limitations. In this article we will analyze all possible reasons for the slowdown —from banal lack of memory to hidden viruses—and give step-by-step solutionsthat will help return the tablet to its former speed.

It is important to understand: if your device is older than 4–5 years (for example, Samsung Galaxy Tab A 2018 or Huawei MediaPad T5), then some of the brakes may be related to obsolescence. Manufacturers optimize new versions Android for modern hardware, and old processors (for example, Snapdragon 425 or Mediatek Helio P22) simply cannot cope with the load. But even in this case, there are ways to improve performance - read about it below.

1. Overloaded random access memory (RAM)

The most common cause of brakes is lack of RAM. Tablets, especially budget ones (with 2–3 GB of RAM), quickly become clogged with background processes. For example, if you have 10 tabs and a game open at the same time, the system begins to freeze as it constantly switches between tasks. Chrome with 10 tabs, Telegram, YouTube and game Clash of Clans, the system begins to freeze as it constantly switches between tasks.

How to check RAM usage? Go to Settings → Device → Storage (the path may differ depending on the version Android and shell, for example One UI u Samsung or MIUI u Xiaomi). Here you will see a graph of memory load. If less than 20-30% is free, it's time to clean.

• 🧹 Close unnecessary applications: Use the "Recent" button (usually a square or three bars) and swipe away all unnecessary tasks. Some applications (for example Facebook or TikTok) continue to run in the background - it is better to close them manually.
• ⚡ Disable autoloading: go to Settings → Applications → Autoloading and disable background work for unnecessary apps (especially instant messengers and social networks).
• 🔄 Restart the tablet: a banal reboot clears RAM and removes temporary freezes. Do this every 2-3 days.

⚠️ Attention: if after closing all applications the free memory is still less than 15%, the tablet may be running malware or there is a system failure. Go to the section about viruses or resetting settings.

2. Full internal memory

When the internal drive is full to capacity (especially if less than 1 GB is free), Android begins to slow down. The system needs space for caches, temporary files, and updates. For example, if you Lenovo Tab M10 have 32 GB of memory, but only 500 MB is free, the tablet will be “dull” even with simple tasks.

Check the occupied space in Settings → Memory. Pay attention to the sections: "System files" (should occupy no more than 10–15 GB), "Application cache" (if more than 2–3 GB, it’s time to clean), "Downloads" (unnecessary files often accumulate here).

• 🗑️ Delete unnecessary files: photos, videos, APK files. Use the built-in “Memory Optimizer” or applications like Files by Google.
• 🧼 Clear cache: in Settings → Applications select each of the frequently used ones (for example, Chrome, Instagram) and click "Clear cache". For mass clearing, use Settings → Memory → Clear cache.
• ☁️ Transfer files to the cloud: Google Drive, Yandex Disk or Dropbox will help clear place. For example, photos can be automatically uploaded to Google Photos and deleted local copies.
• 📱 Use a memory card: if the tablet supports microSD (for example, Samsung Galaxy Tab A7), transfer multimedia and some applications to it (in Settings → Applications → [name] → Memory → Edit).

File types	How to clear	Saving space
Application cache	Settings → Applications → Clear cache	Up to 3–5 GB
Downloads (APK, PDF, ZIP)	File manager → Download folder	Up to 1–2 GB
Duplicates of photos/videos	Application Files by Google → “Cleaning”	Up to 500 MB–1 GB
Unused applications	Settings → Applications → Delete	Up to 1–10 GB

3. Outdated version of Android or firmware

If your tablet has not been updated for a long time, it may slow down due to unoptimized software. Manufacturers regularly release patches that fix bugs and improve performance. For example, updating from Android 10 to Android 13 to Samsung Galaxy Tab S6 Lite can give a speed increase of up to 20%.

How to check for updates: Settings → System → Software update.

If there are no updates, but the tablet is slow, your model may be no longer supported (relevant for devices older than 3-4 years). In this case, it will help custom firmware (for example, LineageOS), but it is risky and requires skills.

• 🔄 Update the system: if an update is available, install it. Make a backup copy of your data first (Settings → Accounts and archiving → Backup).
• 🛠️ Update applications: go to Google Play, click on the avatar → “Manage applications” → “Update all”.
• ⚠️ Reset settings: if after the update the brakes become worse, reset to factory settings (Settings → General → Reset).

⚠️ Attention: custom firmware (LineageOS, Pixel Experience) can improve performance, but will void the warranty and may cause crashes. Install them only if you are confident in your actions and have found the firmware specifically for yours. models!

4. Viruses and malware

If the tablet starts to slow down after installing a suspicious APK file or visiting a dubious site, the reason may be virusesMalware not only steals data, but also. loads the processor, causing freezes. Tablets with Android 8–10are especially vulnerable, where protection is weaker than in new versions.

Signs of infection:

— A sharp increase in battery consumption.

— The appearance of unfamiliar applications in the menu.

— Advertising in places where it should not be (for example, in settings).

— Spontaneous opening of the browser with suspicious sites.

• 🛡️ Install an antivirus: Malwarebytes, Bitdefender or Kaspersky Mobilescanning.
• 🔍 Check the list of applications: go to Settings → Applications and remove everything suspicious (especially with names like “System Update”, “Flash Player” or “Cleaner”).
• 🚫 Disable installation from unknown sources: Settings → Security → Unknown sources (must be turned off!).
• 🔄 Reset to factory settings: if viruses deep in the system, only a full reset will help (Settings → Reset).

How to remove a virus if the antivirus does not help?

If malware is blocking the installation of the antivirus or resetting the settings, try booting the tablet into safe mode:

1. Turn off the device.

2. Hold down the power button, and when the logo appears, hold the button Volume Downuntil safe mode loads (at the bottom of the screen there will be an inscription “Safe mode”).

3. In this mode, remove suspicious applications and run an antivirus.

5. Too many background processes and startup

Android allows applications to run in the background, but some abuse this feature. For example, Facebook or AliExpress can constantly synchronize data, consuming resources. If you have many instant messengers installed (WhatsApp, Viber, Telegram), they also load the system.

How to check background activity:

1. Open Settings → Battery → Battery usage.

2. See which apps use the most energy (even when you're not using them).

3. If there are unnecessary apps in the top, limit their operation.

• ⚙️ Disable autorun: in Settings → Applications → [name] → Battery → Background activity select “Limit”.
• 📵 Prohibit notifications: Many applications wake up to show notifications. Turn them off in Settings → Notifications.
• 🔋 Enable power saving mode: This will limit background activity. Path: Settings → Battery → Power saving mode.
• 🚫 Delete “junk” applications: cleaners like Clean Master or DU Speed Booster themselves slow down the system. Use the built-in tools Android.

6. Hardware problems: battery, overheating, wear

If software methods do not help, the reason for the brakes may be hardware:

— Discharged or swollen battery (if the tablet turns off at 30-40% charge).

— CPU overheating (for example, due to dust in the case or prolonged play).

— Flash memory wear (relevant for devices older than 5 years).

How diagnose:

— Check the temperature: if the case is hot (especially around the processor), let the tablet cool down.

— Look at the battery status: enter in the phone dialer ##4636## → “Battery information.” If the wear level (>50%) or the actual capacity is much lower than the rated capacity, it’s time to change the battery.

— Check the memory read/write speed using the application A1 SD Bench. If the values ​​are below 20–30 MB/s, the flash memory has degraded.

• 🔋 Replace the battery: if it is swollen or holds a charge for less than an hour, contact service. For Samsung or Huawei original batteries cost RUB 1,500–3,000.
• ❄️ Avoid overheating: do not use the tablet in the sun or under a blanket. For games, buy a cooling pad.
• 🔄 Return to factory firmware: if the brakes appeared after the update, perhaps a new version Android is not optimized for your hardware. Rollback via Settings → Reset or ODIN (for Samsung).

⚠️ Attention: if the tablet suddenly started to slow down after falling or getting wet, do not try to disassemble it yourself —this may lead to a short circuit. Take it to a service center to diagnose the motherboard.

7. Unoptimized system settings. data-i="255">Even on new tablets (

Even on new tablets (Samsung Galaxy Tab S9, Xiaomi Pad 6) there may be slowdowns due to incorrect settings:

— The interface animation is too high.

— USB debugging is enabled (loads the processor).

— Incorrect graphics settings in games.

How to speed up the system:

1. Disable animation: go to Settings → About phone, tap 7 times on “Build number” to enable developer mode. Then in Settings → System → For developers install:

— “Window animation scale” → Off

— “Transition animation scale” → Off

— “Animator duration scale” → Off

2. Reduce screen resolution (if supported): Settings → Display → Screen resolution → select HD+ instead FHD.

3. Disable unnecessary functions: Google Assistant, Bixby (u Samsung), live wallpaper.

8. When all else fails: radical measures

If you've tried everything, but the tablet is still slow, remain extreme measures:

— Reset to factory settings (will delete all data, but return a “clean” system).

— Installing custom firmware (for example, LineageOS or HavocOS for weak devices).

— Replacing a tablet (if it is older than 5 years and cannot handle modern tasks).

How to reset:

1. Create a backup (Settings → Google → Backup).

2. Go to Settings → General → Reset → Reset data.

3. After the reset, do not restore data from the backup copy immediately - check the speed of the “clean” system.

• 🔄 Try an alternative firmware: for Samsung — One UI on the Android 12/13; for Xiaomi — MIUI without bloatware (pre-installed garbage).
• 🆕 Buy a new tablet: if your device is older than 2019 and has less than 3 GB of RAM, even a reset will not help for long. Budget options for 2026-2026: Samsung Galaxy Tab A9, Xiaomi Pad 6S Pro, Realme Pad 2.

⚠️ Attention: details. interface and path to settings may differ depending on the version Android and the manufacturer's shell. Look for the latest instructions for your model on the brand's official website or in the user manual.

FAQ: Frequently asked questions about brakes on Android tablets

The tablet is slow. only in games. What should I do?

If the brakes appear only in games (Genshin Impact, Call of Duty Mobile), the problem is graphics settings or overheating:

1. Reduce graphics in the game settings (select Low or Medium settings, disable shadows and anti-aliasing).
2. Close all background applications before playing.
3. Use cooling pad or play in a ventilated area.
4. Check whether your tablet supports the game: for example, Genshin Impact requires at least 4 GB of RAM and a level processor Snapdragon 730.

After updating Android, the tablet began to slow down. How to roll back?

Rollback is possible, but complicated:

1. For Samsung: use the app Odin and the official firmware from the site Sammobile.
2. For Xiaomi: download the desired version MIUI s en.miui.com and flash through Fastboot.
3. For other brands: look for instructions on the forums 4PDA or XDA Developers.

Important: a rollback will reset all data and may block the device if there is an error. Do this only if you are confident in your actions!

The tablet slows down when connected to Wi-Fi. What's wrong?

Possible reasons:

• Weak Wi-Fi signal (check speed at Speedtest.net).
• Background downloading of updates (turn off auto-update in Google Play).
• Problems with DNS (try changing DNS on 8.8.8.8 in the Wi-Fi settings).
• Viruses (some Trojans load the network with advertising).

Solution: reboot the router, forget the network on the tablet and connect again, check for viruses.

You can Is it possible to speed up an old tablet with 2 GB RAM?

Yes, but with reservations:

• Install light firmware (for example, LineageOS without Google Services).
• Use light versions of applications: Facebook Lite, Messenger Lite, YouTube Go.
• Disable all animations and background processes (see section 7).
• Do not install heavy games or applications (for example, Photoshop or PUBG).

Real speed increase: up to 30–40%, but don’t expect miracles - 2 GB of RAM in 2026 is critically small.

How to check if the tablet is slowing down due to the memory card?

Slow microSD-cards (class Class 4 or Class 10 with a real speed of 5-10 MB/s) can slow down the system if applications are transferred to them. How to diagnose:

1. Remove the card and check the speed of the tablet.
2. Test the card for speed using A1 SD Bench (must be at least 20 MB/s for reading).
3. If the card is slow, replace it with UHS-I Class 10 or A2 (for example, Samsung EVO Plus).
