Unhappy LG G2 Doing some really weird things HELP

Okay, so the last few days, I have some problems with my LG G2.... it's on the stock rom, with root and G2 Xposed...


So the first days, everytime I rotated the device, it said "Quickremote has stopped" and when I launched a LG app it said "Apps update has stopped".... Luckily, this stopped after a day, so no big deal for me.... Then, since 2 days ago, my phone doesn't vibrate, and the LED notification light is only working with Knock-On..... Now, since today, only the home button works..... Back button, recent button, menu button.... They all don't work....


Also, I've noticed everyday I've got a little more space free on my phone.... So I don't know what's going on, but it kinda seems like it's ripping itself apart....

I haven't rebooted my device, since I'm THAT scared of a bootloop.....



Can someone please help me?
Love your phone, but never start a mariage with it....
