Why can't mobile phones be used in two places at the same time? What should I do?

If the mobile phone can't normally use the application dual-open software program, you can try to operate:

1. Erase software data: Settings-Find Application Manager-(All)-Find software name-(Store)-Erase data (pay attention to the important data in the backup software).

2. If it doesn't work, please turn off the phone and restart it.

3. Update the mobile phone system version. Note: Please back up the data in the device before upgrading.

4. If it still doesn't work properly, please back up the data of your mobile phone (phone book, text messages, pictures, etc. ) and try to restore the phone to the factory settings.
