my g2 was working fine then it was totally black try to power it on thinking i mustve turned it off and it wouldnt power on. i then plugged it in thinking it must be dead and the charging light doent come on or the battery screen that pops up. took it down to sprint and they couldnt figure it out either
Get in contact with LG, they will fix and/or replace for free. You just have to pay shipping to LG. I did the same thing when my LTE stopped working. Spent $9 for 2 day signature confirmation. They pay for the shipping back. Took 2 weeks total but worked good for me. If you have insurance then Sprint stores should replace it for free if found to be hardware defective and not user error.
