Here I have TCL 10 SE, and today I'm going to show you how to enter save mode on this device. So, first, you have to hold down power key, and when you see this window, you have to hold your finger on power off and after this window appears reboot to save mode. You just have to tap. Ok and your device will be restarted in the safe mode and, as you can see, the sign says safe mode, which is the proof for that. We are now in the safe mode. As you can see, uh internet features are disabled in the safe mode, because I guess its obvious internet is not safe for you, for you and for your life.
If you want to exit safe mode, just restart your device, and it will be restarted in the normal mode. So, thanks for watching, if you find this tutorial useful, don't forget to hit that like button and subscribe to our channel.
