Step-by-step solutions
Review pending changes while the phone responds
Note when it began and what you were using.
Check Android and app updates and available space in Settings. If the phone will not stay on, do not repeatedly force update attempts; seek support for that state.
Preserve important data when possible. Before freeing space, distinguish backed-up content from files that exist only on the phone.
Apply available updates
Follow the phone’s prompts and observe the result.
If the device stays stable enough, save work and apply available official updates. Do not interrupt installation.
Try the activity that showed the failure. If it continues, compare downloaded-app involvement rather than repeatedly restarting as a test.
Advanced checks
Continue if the earlier steps did not help. Read each procedure’s precautions first.
Compare behavior in Safe Mode
How to enter it depends on the manufacturer.
Follow the manufacturer’s official Safe Mode instructions. Check whether the restart or shutdown recurs.
If it stops, a downloaded app may be involved. Return to normal mode as instructed and review recent apps one at a time; preserve their data before uninstalling any.
Consider a reset only as a last resort
Get help if you cannot verify the backup.
First verify copies of important photos, files and app data, and access to the account needed to set up the phone. Do not assume every app backs up automatically.
If earlier steps did not help and you choose to proceed, use the manufacturer’s official factory-reset procedure. Do not improvise another model’s button combinations.
Still not working?
If it also restarts in Safe Mode, give the manufacturer that result, model and Android version. Do not repeat resets or blame a specific app without evidence.
