Sorry about the cell phone. Android.process.acore has stopped running (Lenovo k860i).

Hello, thank you for choosing Lenovo products.

I'm sorry for the inconvenience.

The android.process.acore process is a process associated with the address book. Usually, after you confirm this prompt, you can go to System Settings-Applications-All, find Lenovo Address Book and choose to clear the data or restore the factory settings through backup reset.

Because you can't enter the settings yet, I suggest you restart your phone and try. If the fault still exists, it is recommended that you press and hold the power button+volume increase button when the power is turned off, move up and down through the volume button after entering the engineering mode, and select the wipe option as the primary key to clear the data.

Because this operation will clear the original data, if you have started USB debugging before, you can back up your phone through the music assistant on the computer.

If your fault still exists or it is difficult to operate by yourself, it is recommended that you contact Lenovo's authorized maintenance point for inspection and maintenance by engineers. You can visit/Lenovo/WSI/station/servicestation/default.aspx? MIDH queries the nearest site. The business hours of maintenance stations are generally from 9: 00- 18: 00 from Monday to Sunday, except holidays, and local stations will adjust slightly according to their own operations. I suggest you call for detailed consultation before you go. Please refer to it.

Thank you for your support to Lenovo and wish you a happy life!
