Is there a possible fix for the touchscreen not working after screen gets turned off?

I haven't found a way yet because of twrp problems, but you can try outjusting some kernel settings and deep sleep options with kernel managers. I recomend SmartPack, free and open source kernel manager avaible on F-droid.

I just got one of these basically free from AT&T that I plan to use only for hotspotting, my main device is an S21+.

I have sm-a125u, the only firmware I can find online for ATT is sm-a125u1

What's the difference? Is it the same? Can I flash it? Or can I just flash any other carrier's firmware instead?

I'm not even going to use this thing for anything other than a hotspot, I just want to root it so I can hotspot while tricking the carrier into thinking it's just mobile data use (since I'm on Unlimited Elite plan).

I don't have the OEM Unlock option in my dev settings, tried the time/date trick. So I read somewhere that I needed to flash an Android 10 firmware to it to get that option back, then go ahead and root, then update back to A11, if that's even possible. I don't care about the firmware being a different carrier's as long as mobile data will still work on ATT's network for hotspotting.

Don't look at the countury reagons, If the sim card doesn't work after flashing another reagons fimware you have to SIM unlock you phone.

Okay so does this mean the u1 firmware will be fine to flash on my u?

You still need to find fimware with the same SW REV value or you will have to go through hell to trick the Rollback prevention (RP)

try changing the date and time to something old, if that doesn't work take software updates and they should apear.
1. Disable dev options
2. go to date and time and set the date to something very old
3. Enable dev options
4. Oem unlocking should apear now and you can change date and time back to it's origin.

Do you still have the same issue? If you do, try to possibly downgrade fimware. Flashing older fimware will work without unlocking PBL if it's smasung's official fimware. After flashing older fimware OEM unlocking should appear, and you will be able to flash unofficial fimware images after unlocking PBL.

What's the best way to make my A12 as private as possible without losing Samsung and Google features? I want to have most of the features from my Samsung Galaxy Watch4 and Google apps without any spyware.

And also, is it possible to install apps such as Netflix and ASB Mobile Banking on a rooted Samsung phone?

Thanks in advance!
