The app that is responsible for clocks keeps freezing. The lock screen widget, the normal widget, the status bar clock and the clock inside the app itself all occasionally show incorrect time (usualy between 10 minutes and couple hours before current time; not even always the same). Alarms won't work when this happens and lately it has been happening multiple times a day. When the clock gets "unstuck" it just jumps right to the correct time and sometimes freezes again. The internal phone clock probably work fine based on what the other apps show. It started about 3 months ago as once-in-a-week thing and has been happening daily for a month now (so I obviously restarted it many times during that time).
The device is Hammer MyPhone Energy with Android 7.0. and it is not even a full year old.
