Here's how to restart your Android phone in safe mode.
🔘 Press and hold the power button on your phone for a few seconds until Android prompts you to turn off your phone, as you would normally do for the ######################################################################################39; off.
🔘 Then, hold the Stop button for a few seconds until your phone asks you to confirm that you want to enter security mode.
🔘 Tap OK, and your phone will restart in safe mode.
Note
– In safe mode, you will not be able to open the applications you have downloaded to your phone, and a "Safe Mode" badge will appear in the lower left corner of your screen. You can find the safe mode useful if you are trying to determine if a problem you are having with your phone is due to an application you have installed or to Android itself.
nothing when it comes to disabling third-party apps-you can not disable, say, just the Dropbox-but it's better than nothing.
-Once you're done with safe mode, go ahead and turn off your phone as you normally would by holding down the power button, then turn it back on.
