Reception Problems
I bought my g3 off an ebay seller about 4-5 months ago. its my first android phone. ive owned ios and windows devices prior to this. it came rooted which kind of spooked me cause it was listed as new other (out of box and original package but otherwise new). it was working great for the most part until i started realizing i wasnt getting half of my calls and couldnt make calls half the time. i can use data and text with pretty much 1 bar or more on lte. making and receiving calls is damn near impossible unless i have 3 bars or more on lte to start then atleast 2 bars when it switches to 4g. I really really like the phone and would hate to get rid of it so soon. im half decent with computers and such so i decided to try and troubleshoot this problem. it could be hardware related but i honestly feel like its software related. maybe there was a crucial ota update it missed due to being rooted? i updated to stock lollipop from stock kitkat to start and updated the modem to the d850 20f version i believe it was, no improvement that i noticed. i kept doing research and found another modem update 20q i think it was and that seemed to improve the reception problems a little bit. i was now getting a little bit of service in areas that i was getting no service prior to this. i have since removed root and took the ota update that was available, no luck. now before going any further with the ota updates im going to reroot (hopefully i didnt lock the bootloader with the last ota) i forgot that some of those otas will do that. im going to try changing the build prop from 9 to 12 and see what that does. theres also a custom rom i came across called spectrum thats geared towards better reception that im going to try. if anyone can give any further advice or ideas please do. im ready to throw the thing out of my car window sometimes lol.
the 30 dollar windows phone that this replaced has better call performance than this g3.
