Here’s the translation:
Hello, I have a similar problem with Android 4.2.1. It happens both on the official and custom (Leva) firmware. The program file in XP is saved in the folder [b]system\app[/b], the file with settings remains in the folder [b]system\etc[/b], the configuration files in the folder [b]data\data[/b] are accordingly deleted. Either the system or the program itself does not restore the settings from the backup file. I'm ready to provide any files for analysis if you need them.
And I would like to ask the developers: Sirs, can anybody say anything on this issue? You know Russian-speaking users usually don’t speak English and they try not to contact foreign developers. But this is the second Russian user who overcame his feeling of insecurity and seeks help at the English-language forum. But until now, both users can not get professional help. To my mind, it’s HIGH TIME to explore the issue and to help these and other Russian-speaking users.
