I just upgraded to android 8.1 on my pixel II and got locked out. To all appearance the new version of the OS doesn’t accept the unlock pattern that I use. The unlock pattern has a knights move step which does not appear when I make the motion to draw it. Sigh…
I think I will pass on iOS 11.2.1 update that is available right now. Won’t have a phone to use after these tech giants are done win their pissing games…
