hi, having a major problem with my unlocked Samsung Galaxy S4 (originally was ATT). its been working fine since October 2016, suddenly since July 2017, last month VOICE calls are simply not working right, normal. If you move 20 ft from were you are calls drop, if you're driving, forget it, no luck. Here's what I know, so far: 1- In july 2017, there was a VERIZON, outage, a tree or something, in Queens NY, came down, took out VERIZON's fibre network at around 2am, its a public news story, google-able. At that exact time, my metropcs service cut off for about 1 hour, I dont know why. I dont live in Queens i live in long island. Just a point i wanna make. 2- Since exactly that time, my voice call service has not been the same, can't drive and talk, can hardly even walk and talk. I've gone thru settings 50 times over and can't figure it out. 3- the #metropcs dealers, I've spoken to 5 including the corporate store in Westbury, they have no clue, i've got 5 different reasons, suggested about service and 611metro support says the stores are wrong. The reasons give to me from the stores are A: because i havent updated my appz (ridiculous), B- Because samsung changed the frequencies anything below S6 won't work (ridiculous) C- Because Metro changed the frequencies D- its an issue with any unlocked ATT phones on the metro network, and E-metro changed the frequencies and anything below Android 7 won't work. 6- Living in NAssau county, it gets worse when i hit the queens border or down by jones beach areas. This was never a problem pre-july 2017 I really need to know, anybody else who's having this problem or solved it, I dont wanna keep buying phones. I tried and old Tmobile phone/prepaid on tmobile and it works thru the whole queens, long island area, no problem. If metro truly "shares with tmobile" then why does my tmobile only phone work in the regions Metro does not, including my own street, including, all my above points (walking 20 ft, etc..)/ Thanks in advance.
