I upgraded my Galaxy S4 to Android 4.3 last week and since then it has quite frequently hung or frozen for 3-5 seconds randomly.
Seems I’m not the only one to experience this but never fear, a factory reset fixed it for me!
Backup everything you don’t want to lose before doing this, as it will restore the phone to how it was when you took it out the box; I copied to external SD card them removed the card just to be safe: –
- Turn the phone off
- Hold Home, Power On and Volume up, keep them pressed until the “recovery mode” text appears, immediately let the 3 buttons go
- Use the volume keys to select “Clear Cache”, press the home key
- Now select “Factory Reset”
- When it’s finished select “Reboot device”
You’ll still be on Android 4.3 when it comes back up and for me, it fixed all the freezing issues.
