I've read another post about the same thing, but I cannot add comments there so here we go, last comment there was in ~april. I am on latest patch. I am not sure how to provide logs, or anything of the sort. I only really noticed it with Facebook Messenger, but I assume it's system wide. If I mute and unmute notifications it works for a while.
If you can show me how to make an actual report from the phone with logs, without installing any c**p that would be great, if you wanna fix it that is, because this issue has been around for a while. S*** like this wouldn't happen if you didn't try and fail to reinvent half the OS for the 10th time, for absolutely no good reason, when there's AOSP that already looks/feels great. I knew I would have problems when I bought this phone but **bleep**, this is just sad, how the f does this even happen I am very curious. Just venting my frustration. Have a good day, and please fix your s***!
