I woke up this morning and my phone app grid was set to 8x5. When I try to change it, there isn't any options. I tried to power off and on but it didn't make a difference.
Hello, I had the same problem, really dont know what was the problem but I did a Factory Reset just to the settings and it fixed the problem, as its just settings, it didnt delete apps or pics or anything. Hope it helps you too.
