Nope. Others are affected too. Even people with a 1V have this problem.

I do get updates but they don’t fix the “device is not certified” issue in the playstore. This akso makes some apps refuse to work and google wallet is also disabled. The only solution I found was to root my phone but now face verification in banking apps is not working :( if you google this issue you’ll find that there are quite a few users with this issue.

I have an XQ-DE44 that I bought in tokyo and I’m now in europe.

On one hand, yes. However, they have absimal software support (2 major os updates and little to no updates in between). I’m also now having a problem on my 5V where my device is “uncertified” on the play store. I found that lots are having the same issue while Sony provides no solution at all. I had to root it to fix it.
