What should I do if my mobile phone system gets stuck after upgrading?

If the mobile phone system is stuck and memory consumption is serious after upgrading, I suggest you.

Restart the machine

If the machine is stuck, it is recommended to restart the machine. If the battery of the mobile phone is built-in, please press and hold the power button and volume button at the same time for more than 7 seconds to restart the device.

Intelligent manager

If the operation is normal, and the mobile phone supports intelligent manager (or memory manager), please close the automatically running application through the functions of application management and storage in the intelligent manager, delete unnecessary data such as cache, residue and advertisement, and free up storage space.

Restore factory settings

If it is invalid, back up data (contacts, text messages, photos, etc. ) and try to restore the factory settings.

Samsung after-sales service center

If the problem still exists, please bring the machine, purchase invoice and maintenance card to the local Samsung after-sales service center, and the engineer will help you reinstall the version of the mobile phone system.
