Random reboots driving you crazy? Phone restarts while gaming, watching videos, or even when locked? This happens on Samsung, Xiaomi, OnePlus, Realme, Vivo, Oppo, Google Pixel — literally every Android device. Good news: 98% of cases are fixable without losing data. Follow these 22 fixes step-by-step until your phone stops restarting forever.

Table of Contents

1. Simple Restart & Remove Phone Case

Start here — works more often than you think.

  • Press and hold power button → Restart
  • Remove thick or metal phone case (they trap heat and trigger reboots)

2. Check for Overheating

Overheating is the #1 cause of random restarts.

  • Don’t play heavy games while charging
  • Avoid direct sunlight and hot car dashboards
  • Use phone in cool environment for 30 minutes and test

3. Boot into Safe Mode (This Tells Everything)

If phone stops restarting in Safe Mode → a third-party app is guilty.

  1. Press and hold power button
  2. Long-press “Power off” option on screen
  3. Tap “Safe mode” → OK
  4. Use phone normally for 1–2 hours
  5. If no restart → exit Safe Mode and uninstall recent apps one by one

4. Remove Recently Installed Apps

Common culprits: cleaner/booster apps, game boosters, custom launchers, RAM cleaners, free VPNs.

Uninstall anything installed in last 7 days and test.

5. Clear Cache Partition (100% Safe – Deletes Nothing)

  1. Turn off phone
  2. Press Volume Up + Power until logo appears (method varies slightly by brand)
  3. Use volume keys to select “Wipe cache partition” → Power button to confirm
  4. Reboot system now

6. Update Every Single App

Outdated apps cause crashes → system restart.

  1. Open Play Store → Profile → Manage apps & device → Updates available → Update all

7. Install Latest Phone Update

Go Settings → System → System update → Check now

8. Stop Background Apps

  1. Settings → Battery → Battery usage → tap heavy apps → Restrict background usage

Many brands have hidden auto-restart feature.

  • Samsung: Settings → Device care → Auto restart → Turn OFF
  • Xiaomi/Redmi: Settings → Battery → Schedule power on/off → Disable

10. Disable Developer Options

Wrong developer settings can trigger reboots.

  1. Settings → About phone → tap Build number 7 times to hide it again
  2. Or go Developer options → toggle OFF at the top

11. Check Battery Health

Swollen or old battery = random shutdowns/restarts.

  • Look at back — if phone is bulging → battery issue
  • Use app “AccuBattery” → check health percentage

12. Calibrate Battery (Old But Works)

  1. Drain battery to 0% until phone dies
  2. Charge to 100% without interruption (6–8 hours)
  3. Unplug → restart → use normally

13. Stop Using Phone While Charging

Especially heavy games — causes overheating → restart loop.

14. Remove SD Card

Corrupted SD card can force restarts.

Power off → remove card → use phone for 24 hours → test.

15. Scan for Malware

  1. Install “Malwarebytes” from Play Store → full scan
  2. Or use built-in Google Play Protect (Play Store → Play Protect → Scan)

16. Clear System App Cache (Advanced)

  1. Settings → Apps → Show system → Android System / System UI → Storage → Clear cache

17. Disable Always-On Display

Causes wake-ups → reboots on some phones.

18. Turn Off Adaptive Features

  • Settings → Battery → Adaptive Battery → OFF
  • Settings → Network → Adaptive connectivity → OFF

19. Reset App Preferences
