Question:

How do I exit the maintenance mode on my device?

Affected models : All T OS or later version models(since S20) except for One UI 6.1.1 version

Answer:

You can terminate the Maintenance mode through 1) Quick panel  (or)  2) Device care on Settings on the device:

[Method#1] : For all Android T OS or later version devices(since S20) except for One UI 6.1.1 version
 

•  As the device is locked by user, the device is required to enter the lock code before getting out  of the Maintenance Mode.

[Method # 2] : For One UI 6.1.1 version devices only
 

• In case you can't access to the Settings or Device care menu, you can access to the menu directly by searching for 'Device care' or 'Maintenance mode' on the app screen search bar. Then you can enter the Maintenance mode to terminate it.
