I bought a brand new LG G4 from ebay four months ago, but lately it started to be non-responsive often, I had to take out battery and put back to start it, it also constantly reboot by itself. From google I found out it was a common problem of LG G4, LG admits the bootloop problem is a hardware fault. I sent it to LG for repair. But they LG refuse to honor warranty and won't repair it unless I pay. What made me angry is, if this is a known defect of their product, they should fix it, instead of making customer to pay their defect. Any one has the similar experience and how you handled it?
