I recently got a lg vu phone from my friend because my phone broke. When i got it she told it didnt hold a charge. I reset it that day and had it on the charger for the night while i slept. The next day the phone had 3 bars untill almost 8 pm witch is good. But today my phone had died while i was out and when i came home i put my phone on the charger and normally it would just turn on and charge but today it just went to the AT&T screen and then it turned off, then when on the AT&T screen again and then turned off and it stills repeats itself. I dont know what i should. Should i get a new battery? Should i just leave it on the charger for a couple hours ? PLEASE help !
My daughter's LG Vu did the same thing. You might want to check at an AT&T store to see if the charger itself has a problem. They may have another charger to try. They charged my daughter's phone on their display charger for me. We ended up having to do a warranty exchange on the phone because the problem was the phone. A new battery might help, if you don't spend much on it. The Vu is an older phone and just might be finished.
You may need to upgrade with AT&T if you are able to do so now. If not, you can try ebay or craigslist for an inexpensive replacement. Also, AT&T offered us a one time replacement of one certain phone for $40. It was a once in a lifetime deal for that line-her phone got wet and would not work correctly. She was a student and could not afford a more expensive phone, so this worked for her. You might ask at an AT&T corporate store about what phone they might have available now as a one time deal. This was not an upgrade, it just allowed her to get another phone without paying the full price.
