While I will chastise you about the lack of backups, XDA Forum (use google to find it) has other tools that could help.
It appears what happens with PCs and the lessons there didn't help folk when they got their new computer based phone.
I set a new password yesterday and, naturally, forgot it almost immediately. After forgetting it I received two calls which may or may not have been important.
After installing the Dr. Fone App I discovered it does not work with my Xperia Xa2.
The methods that will work wipe my data- including my calls log.
I cannot switch to a different account or create a new one because, after changing my password, I switched my phone off and, since I was the last user to log in, the alternative accounts are greyed out.
I cannot transfer data to an SD card or computer because my phone is locked.
I cannot boot the phone because, for whatever reason, Xperia Xa2 is not compatible with booting software.
I cannot control my phone via my computer because my phone must be unlocked in order for the software on my computer to recognize it.
I tried taking a flash picture of my phone screen (I think I heard somewhere that doing that helps.) The screen turned off, but the blocker remains.
I cannot expand the notification without getting into the phone.
From where I'm sitting, it appears as though I am stuck in a catch 22. I need to access my data, but to do that I must unlock my phone. In the process of unlocking my phone, I will lose the data I need to access.
Possibly with the calls log issue I can go through AT&T (I'd rather not, but desperate times call for desperate measures), but where the other data is concerned... I really don't know what to do. Where there's a will there's a way, but it seems I am truly stuck.
It's funny in the worst way possible because it's such a ridiculous absurd situation,
Hopefully somebody will know what to do. I honestly have no idea.
