Ever since I updated to Nougat I've had problems with the phone because it has become slower and sometimes it becomes unresponsive. For example I'm browsing Reddit and then the app freezes but I can still access the notifications and then the notification screen freezes for a couple of seconds. Another problem I've had is that after the screen turns off and I try to power to turn it back on the screen won't turn on but the function keys will, and then after what feels like a delayed response the screen turns on. I reset my phone a few weeks ago because of this problem and it did seem to help but now it seems like this bug has come back.
