Drop the fabric cases once and it's gone. Happened to mine, tore it off completely when it was knocked off a table by someone else
Screen was tinted blue if you didn't look at it direct, this was a problem with the first few that was rectified I think, speaker had a tinny, strange sound to it if I turned them up a certain volume (found a fix for this but it involved poking a hole in the speaker grill) also had WiFi connectivity problems at home where the phone would just lose WiFi signal and spend ages trying to get an IP address, even if I set it up as static, which disappeared entirely since I got my OnePlus. Only thing I miss is the camera, that's it. I think I just got unlucky as I got one of the first few.
I brought this one: https://www.amazon.co.uk/Spigen-F17CS22280-Google-Crystal-Protection-Clear/dp/B0747813GV The spigen range are meant to be really good. I wanted something clear this adds a bit of bulk but great grip and protection around the sides etc. The original google fabric cases look great but are a little slippy on the hand and may stain with dirt after long use. Not sure about screen protectors I had a bad experience with mine it was a flat one but the edges didn’t stick! I think the ones that include a black top and bottom bit are meant to be good but you will need to make sure they are case friendly if you have a thick case.
Anyone recommend a case and screen protector please I've ordered this today should be here Friday Thanks
What technical issues?
