Mine is still working. It stopped working first of february and i did the date change and it was back again. For the second time in row, it stopped working at a change of month. My last phone had a problem with a silent mode. It was android too, and the problem occured every time that month had 31 days. If less than 31, no problem, but every time the month had 31 days, i couldn't get silent mode off. There was pretty simple workaround so it didn't bother me too much. But can this fingerprint problem have a similliar issue? It has worked now really good for almost two months, and when it stops working in a day 31th, I take the date back and skip 31th. I feel like a crazy person because this sounds insane.
Yeah I wish I had more time to test on Pie but I upgraded to 10 almost immediately and the fingerprint has been hit or miss from the start, but for the past day it's been quite bad.
Now it won't unlock unless I completely wipe down the sensor and make sure it's 100% clean, after which it unlocks just fine, but after that it won't unlock till I clean it again.
Quite frustrating, but judging from what I've read, it seems like Sony messed up big time with the Android 10 update for the X1, so I can imagine me and many others are eagerly waiting for a new update.
By the way, do you have any issues on a 'converted' device? Anything not working as intended? And do OTA updates work or do you have to flash every new build manually?
