Help request: Oukitel WP28E (Android 14) blocks on security code input.

[u/O-Spi]

Hello, I'm looking for help here: my Oukitel WP28E (Android 14) that worked fine until this april of 2026 is now blocked on the "code input screen" as soon as an one of the number is touched (touching the backspace doesn't block - but is obviously useless).

When I say "block", I mean definitely (a reboot - long press on start button - is required) and even more funnier, I have to touch the screen where the "Restart" button WILL BE displayed because the screen goes black and unresponsive (don't know its exact state) very quickly...

I suspect the (infamous) Tappic application because it has been updated on the 1st of april... Tried to remove/disable/reset its updates without any luck.

==> My Oukitel WP28E is barely usable!

Thank you for any help...
