Here are two ways you can try to get out of Safe Mode. I cannot say which (if either) will work on your phone. It is going to depend on the OS.
First option...
To get out of Safe Mode, please try the following.
First... Touch and Hold the Power key.
Next... Tap Power off.
Finally... Once the phone is off, Touch and then Hold the Power key again to restart.
The phone should now be out of Safe Mode.
If this doesn't work, then try this.
Second Option...
Use the Status Bar to turn off Safe Mode.
Pull down (swipe) the status bar of your phone.
Now tap the "Safe Mode" button. This should turn Safe Mode off. Your phone should now automatically restart, so that it boots up out of Safe Mode.
