The app launcher stops unexpectedly and the settings can t be opened

Did you delete the "launcher" when you cleaned up the software in the system after rooting? If yes, then you either install a desktop (there are ** on the Internet, a lot, adw go and the like), or flash the firmware, please see method 3 to flash the firmware.

Method 1: Shut down and start again.

Method 2: Pick the battery and turn it back on.

Method 3: Re-flash the firmware, swipe the card, put the official upgrade package in the memory card, and press and hold the three keys of "small house + volume + power on" at the same time, the progress bar is finished, and the phone will automatically restart.

ps: Use method 1 first, then use method 2 if it doesn't work, and then use method 3 if it doesn't work. Method 3 can generally be completely solved, if even method 3 can not be solved, then you can find after-sales maintenance or return to the factory.

If it is a program that appears at boot, see if there is this option in the boot startup, if there is a removal of it, if it is a system process, the above method is not applicable.

2) If the above methods can't solve the problem, first soft and then hard, reinstall the operating system, don't install software, patches, drivers, etc., and see if there are still problems with booting? If you don't install drivers, patches, and software step by step, and find something that isn't suitable, don't install it.

Please note: If you restore the system or reinstall it, when installing drivers, patches, software and other things, be sure not to install the things that affect your accident this time, otherwise it will be restored or reinstalled in vain.

3) In terms of hardware, such as whether there is a problem with the hard disk, memory, etc., whether the temperature of the CPU and other hardware is high, if it is caused by hardware problems, it is recommended to overhaul it.
