I've had my LG G3 (model LG-VS985) for almost 2 years now. 2 days ago I was simply watching youtube and it randomly turned off. I was on low battery around 15%, but it has never shut off on its own, not until it was past 5% (which I wasn't past). I have tried so many things to get my phone to work again. I have tried charging my phone. Nothing lights up when I charge my phone. I have tried: removing my battery, hard resetting, resetting my phone while phone was plugged in with no battery, holding the power button with no battery, and even completely taking apart my phone.
My phone has no obvious damage to it. Of course I've dropped it throughout the time I've had it, but I have never had a problem with it after. Like I said, there are no cracks, dents, or obvious damage on the phone. I tried taking my phone to a local Verizon store, but they only were able to advise me to do the same things I have already been doing. The online chat has given me the same answers, along with LG customer service.
I am completely out of ideas on how to fix my phone. The only thing I haven't tried yet is trying a new battery. Does anyone have any ideas on how I can try to fix my phone without it being sent in for repair?
