Hi, my English is bad, I'll try to help you. First, you have to go into the "data" files of your phone and look for the folder called "save". Copy its contents and paste them into the "save" folder of GeneX 2.
If you can't access the data folder, you need to uninstall the updates for the app that manages your files and delete its data. I recommend opening another file management app from the Play Store or Google Play to enable access to the phone's locked files. For about three years now, you haven't been able to access the data files without another app and the method I mentioned.
I use ex file explorer because it's very easy to use and has no ads.
