    Hello I’ve had a problem with my Xperia Z3 where I get a poor LTE signal and constant loss of GPS during use of Google maps now that I got the phone apart to fix the screen will swapping out the PCB board fix this problem?

    • Santosh Das says:

      This is problem of the phone. You cannot do much. Update the Software and check.

      • Shane Torresan says:

        Don’t think it’s a software issue but if any thing I could try flashing a different firmware as there is no more updates for this phone it’s a Rogers phone from the east coast and I’m a Fido customer on the west coast basically the same network so I don’t know it could be a problem in the motherboard with one of the components and yes if so there’s not really a fix
