Sounds to be software although you cannot rule out hardware issue completely. First, you should try to factory reset the device. While off, god the power button and volume down button. When the LG logo appears, release and then re-hold the power button while always still holding the volume down button. The factory set menu will appear and you can attempt to reset the device. This should fix all you problems.

It is a hardware problem. The processor is unpacked. You have to heat up the motherboard , but is a temporary solution. After a time the phone will do the same problem.

Not sure...but I had the same problem and fixed it. I opened up my LG G3 (unscrewed it open), took out the motherboard. Preheated my oven to 350° fahrenheit and stuck it on a cookie sheet (on foil) for 9 minutes. Put it back together and now my phone works even better than before...it's a lot faster. I found this trick on YouTube. Look it up...it works. I'm super happy that I didn't lose any of my internal photos.

This procedure worked for me. Baking the mobo allowed it to start up again, like magic.
