How to boot a smartphone in to safe mode

 Safe mode in smart phones is similar to safe mode in Windows, where your system starts up without loading any third-party add-ons. Try to use any of this techniques in your android smart phone. Unfortunately there  is no standard method and depends on cellphone or  tablet device manufacturers or versions.

Method 1

Press and hold the power button as you would to power down or reboot.

A menu will pop up.

Tap and hold the “Power off” option.

If nothing happens try the same with “Reboot”.

A dialog should appear offering you to reboot in Safe Mode. 

                 

Method 2

• Power down.
• Turn on and repeatedly tap the soft-button for “Menu.”

Method 3

• Power down.
• Turn on, then press and hold Volume Down (Galaxy S3 and others), Volume Up (HTC One and others), or Volume Down and Volume Up together (various Motorola devices) when the vendor’s logo appears.

If you have managed to select Safe Mode, you will see the text “Safe Mode” at the bottom left corner of the screen.

                

After booting into Safe Mode, third-party apps will no longer show up on the Apps page. You can now peruse on your installed apps for any issues.

To get out of Safe Mode, try simply rebooting.

If that doesn’t work, try rebooting using one of the button-press options listed above, starting with the one you used to engage Safe Mode in the first place.
