First things first. 'Sony xperia tablet Z wifi 16gb' is my first tablet and android device.
I upgraded it to 4.4.2 and I'm really disappointed about the restriction to write on the external sd card. I read about the new changes on the android official site, but there was nothing about sd card write permission changes. I didn't see it coming.
Is there a way to fix this problem without rooting the device? I never done something like that, I don't want to loose my warranty and it seems that there are many thing to consider.
I read that if backup my TA partition, I can eventually restore it later and keep my warranty, but I also read that I need root permission to do such thing and my bootloader must be locked. And some root procedure requires the bootloader to be unlocked.
If I root my device I won't be able to update it with official update, I'll have to do it manually.
If I change ROM, MHL won't work anymore.
Is that all right? I'm confused :\
I also don't want to loose my purchased app, my settings and my savegames.. I really spend a lot of time on this tablet. A simple backup will resolve all of that?
Is there a way to fix everything?
Thank you for your patience and your time.
