    Hi. My Verizon Galaxy S4 seems to have developed a problem where Google Maps looses the GPS signal just as it is starting a route. When I open Maps, it seems to know where I am. When I ask it to plot a route, it seems to do so correctly but as soon as I start Navigating, I get the message that it cannot locate the GPS signal. Then in about 5 minutes or so, sometimes longer, it seems to find the signal. This is been happening for about 2 months. I read some posts where it was suggested that I open the back and tighten the screws, which I did, but I can't say it helped. Then another post said to remove all of the screws and fool around with the antenna and the contacts and such, which I don't really want to do because I know I'll break something. Funny thing is my contract expires next month, and something in the back of my mind says that this is built into the unit, so when my contract expires I will want to renew it and buy a new phone. Does anyone have any suggestions? Thanks, Dave

    If the GPS icon keeps blinking, try this:

    Open the Phone, as if you were going to make a phone call and dial -
    *#9090# -- Diagnostic Configuration (*#197328640# if that doesn't work)
    Menu, select Key Input, enter Q
    Menu, select Key Input, enter 0000
    wait for the next menu. (It takes a while.)
    UMTS->COMMON->NV REBUILD->NV REBUILD->SYSTEM->PROTOCOL->GPS->IMS
    or, if you don't have UMTS:
    UE SETTINGS & INFO->SETTING->SYSTEM->NV REBUILD->ALL

    Restart the phone.

    Does this restore the phone to its factory settings and I lose everything?

    Rubkat, will this restore the phone to factory settings and I will lose my apps, pix and files?
