Android 15 blocks ability to unlock tablet: DO NOT UPGRADE!!

[zevrix]

Hi everyone, it's my first post and hope it will help others not to do the same mistake:

I've just upgraded my A9 tablet to Android 15. What a mistake.

Turned out that Android 15 is a faulty system that blocks the normal ability to unlock tablets.

When you swipe the lock screen the usual way, the pattern does NOT appear (and neither does the PIN keypad). Instead of this now two useless arrows appear (on the left and right sides). The arrows don't do anything (only bring to another empty screen). What is this nonsense for??

After a couple of hours of testing, I found out that the pattern will appear only when you first press the side button to put the tablet to sleep, then press it again to wake the tablet up. Then, after swiping the lock screen, the pattern will appear as expected.

In over 15 years of using Android, it's the first time I see they release this kind of faulty - and DANGEROUS - upgrade.

DO NOT UPGRADE to Android 15 under any circumstances!

I sure googled for solutions for this issue, but this particular problem wasn't listed anywhere. Plus it looks like most results now are some kind of AI-generated content that list features and settings that don't even exist.

Does anyone have any idea how to make Android 15 behave normally, if possible at all? Any help will be greatly appreciated.

Thanks,
Leo

I cleared the device cache in the recovery mode, and the problem went away after the initial tablet reboot.

However, after the tablet went to sleep, the problem came back.

(And yes, I disabled and re-enabled my pattern, and switched between pattern and PIN several times already.)


Enormous time has already been wasted due to Google's failure to test their software properly.


At this point, two things are clear:


-Android 15 is a faulty and dangerous upgrade that should have never been released.


-It's also unacceptable that Samsung allows to upgrade to Android 15 on their devices. Samsung should have BLOCKED this faulty upgrade until it's suitable for running on Samsung devices.


Both Google and Samsung are responsible for this disaster and must address it immediately.

I'm sorry to hear you have an issues, I would maybe consider doing a factory reset if all else is not working. First do a backup through your Samsung account for settings and all.

Thanks! It looks like I'll have to do this eventually when I have time.
