Along with an ever growing list if complaints, I'm now getting Samsung Reminders reminding me at the wrong times. I used to have no problems, but recently my Reminders, which I have on every work day, pop up late, like 20 mins or so.
It's annoying that, poor battery life, alarms sometimes not coming on, Reminders not on the right time, and sometimes my mobile internet connection refusing to connect until a phone restart, all add up to a frustrating experience. The phone (S22 Ultra) was good at first but over time has gotten worse. It'll have to be reset which is a chore, but will be the first port of call. I find myself doing this more often on Samsung phones these days.
The solution.... just move away from Samsung addiction. They are not the innovators anymore and you'll have less heartache and expense in the long run.
