Since some weeks I noticed a new behaviour of my FP2 (still Android 6): Alarm events like calender alarm, but also SMS or even a countdown timer are delayed by hours. I tested this by sending test SMS from one SIM to the other and at the same time one from the other SIM back, and it took 3hours 40 minutes to be delivered, and the same for the other direction. Starting at 11th of january I noticed it for SMS, because I get SMS from a control system every day at 12:00 (and for some events at other times from the same system) with a time stamp, so I can check the sending time and the receiving time. The delay is sometimes less than one hour, sometimes more than ten hours. Same is for calender events, they sometimes popped up three or four hours later. And a countdown timer, which I used very often, should ring after 20 minutes, but rings about one hour later (when the app is closed).
It’s no matter of the SMS provider, because its the same for the two different providers (O2 and Vodafone), its no matter of a single app, because it happens for different apps.
It’s very anoying for two factor authentication, no system allows a delay of hours.
A reboot solved it for some time (a day or so).
I did’t install a new app at that time. The only thing is, that the memory is quite full (24 of 25,48 GB, App memory 1,8 GB, free 295 MB), but this did’t change in the last weeks.
I didn’t found anything similar in the forum, but maybe there are other people with the same problem.
And what could be the reason for that?
(I just see, that I didn’t understand the new forum structure, this should be at help/FP2, maybe someone is able to move it)
