    LG G4 on Sprint

    Android 6.0
    Model #: LGCS991
    Software #: L8991ZVE

    So, I updated Android and 2 days later i get the "Unfortunately..." messages. i cannot access the rear camera. I cannot answer calls or hang up outgoing calls (other then remove the battery) due to the call app not launching and giving me access to the 'answer' or 'decline' buttons.

    I've been searching around the net and tried the following:

    rebooting the phone and removing the battery overnight = failed
    clearing cashes of both camera and call app = failed
    booted phone in safe mode = failed
    factory reset = failed

    Took the phone to Sprint store. They insisted on making me do all of the above listed again, which is fine, they have protocols I guess. Afterward, no success. Since I do not have insurance on my phone (why would I pay $17 a month? I take good care of my phones), that I could pay $75, send it off for a week+, and have Sprint maybe fix my phone. Repair is NOT guaranteed.

    Sprint is not willing to work with me, perhaps someone has a solution that has worked? Is there a way to downgrade on these Sprint phones? I've seen Verizon solutions involving such, but I'm not rooted.

    Any help will immensely appreciated.

    Welcome to Android Central! Was this an official update pushed to your phone by Sprint? If so, I would contact Sprint by phone and ask to escalate to a higher tier of support. Explain to the first tier support that you've already tried all of the above steps, and that since the update pushed by Sprint caused this problem, then Sprint should take some responsibility. Be polite, but persistent, and keep asking to speak to higher-level managers if you're not getting anywhere. Don't get mad or threatening, since that will make customer service just shut down and refuse to help completely.

    Thanks for the reply.

    I've worked my way through the echelons of Sprint's tech support only to find out that the amount of technical help they provide is the same as 30 min of time spent here or in xda... I was told to take it to a repair store and have them run a diagnostic. I plan on doing that soon, but I don't have high hopes.

    SOLUTION:

    So Sprint would not help, nor would they let me return the phone and cease those dumb monthly payments they make their customers endure now.

    So, I removed the micro SIM card from the phone and did a factory reset. Camera now works. Haven't tried the call yet because I haven't switched back from an old phone, but plan to do so tonight.

    Hope this corrects the problem for someone else out there. I missed my 4G after having to resort to an old HTC one...

    CORRECTION:

    Problem began again with the Call. The Camera seems to work fine now.

    If I remove the microSIM card and boot the phone, everything seems to work, call, camera, etc. When I put the SIM back in, the error message returns for the Call app.

    So, I took the phone to a Sprint store hoping that they could either replace my microSIM or something. I was told the phone needed to be replaced. The rep told me that the G4 had a bunch of bad phones with bad processors and that replacing the SIM would do nothing because the SIM card is what runs the phone...which I thought to be an outright lie. He just kept plugging the LG G6...

    Result: A return to a plea for help if anyone has a solution...
