[ASUS ZenFone 8] farmatito:
Hi,

I would like to ask for advice about latest OTA .326 keeping failing (see attached screenshots). I contacted already Asus support but besides telling me to reset my phone they were not of great help.

What bugs me is what a see in logcat:

This looks like a failing internal memory and I fear that my Z8 will be another case of sudden death rather soon.

I would prefer not to reset my phone. I would do it only if I could unlock the bootloader and install a custom rom, but this seems impossible for now.

Any hint or advice on how to solve this problem is appreciated.

Thanks in advance for your time.
