Re: Can i go back., before oreo?

I am so disappointed with Sony firmware that an upgrade would be to buy a Nokia 3310 !!

Even this forum on my Sony XZs is troublesome to type. 

Never ever buy a Sony phone again is my advice. 

To resolve all the issues I had with wifi not connecting and / or dropping out on Oreo, I had to go and buy a different router as I eventually worked out that TP Link hardware was not compatible.
