🔸QuickSupport🔸
Software for remote operations.
🔸Settings🔸
The specific settings in it are the same as the settings of the Android phone used in daily life.
There are two important settings in the system.

The first one is the setting of time. 

After the KEY TOOL PLUS is turned on, it needs to be activated. If there is a time issue and synchronization is not possible, it will continue to prompt network failure. 

When encountering such problems, it is necessary to manually set the time by entering that position.

The second important function is to restore factory settings. 

If you use KEY TOOL PLUS for a long time and the memory is full, you may need to perform a factory reset operation to clear all data inside. Please note to save the files we need to keep before performing this operation.
