Hi dear. I'd buy a BV5000 and is come with Android 6.0 I dislike the impossibility to use the SD as default programm data folder. Trusting is not the impossibility of using my phone as i want. I don't want to format Ext4 and crypt all my data.
I want to put MINE data where i want. All risks are mine.
Is possible to downgrade mine android 6.0 to oldest 5.1 ?? What i have to do ?? Have You an app to backup all before doing this downgrade ?
