Just got a new replacement for this phone and it the blue light on the lock button comes on when I plug it in but it doesn't show the battery charging. Same thing with the old one I just sent in and got this one for. Will not power on or charge. Only change is the light at the top flashes occasionally. Any ideas?
Try removing the battery and put it back after a few minutes. Try to charge using a different charging cable. I also suggest that you take it to a cellphone shop and have an expert check it or contact LG for assistance regarding the issue. Good luck!
