Third-party problematic apps, just like the minor glitches we suggested before, can be tested through a general method, booting into Safe Mode.

That’s because these apps are blocked in Safe Mode, so you have a problem associated with the normal running mode.

Still, how do you boot into Safe Mode?

  5. Keep holding the latter until the restart process finishes and the bottom of your screen is already displaying the Safe Mode label;
