Iphone 12 Low Recieve signal

dial *3001#12345#* on that screen tap the 3 lines next to the home symbol. on the next screen tap Rach Attempt and scroll to "rsrp" and that negative number is the actual signal strength in decibles where anything below -100 is a low to bad signal -91 to -99 is a weak signal -100 to -120 is a poor to no signal.... if all these iphone 12 are showing this they either have an antenna issue or a software issue. you can design the operating system on the phone to report more bars for a lower signal but the rsrp is the raw signal coming to the phone and not converted to bars.

Sooooo, Me and T-mobile settled on an agreement after their engineers went and performed several driving tests with an Iphone 12 and an Android device ( Galaxy s21). Their conclusion was, the Iphone12 had quite a bit of a lower receive signal than the android device, meaning the Iphone device has issues with the receiver or the receiving antenna. They recommended a device exchange and to avoid having the same issue again I went back to the Android device since Tmobile was offering an even exchange for the Galaxy S21 ultra.........

they are still checking in to the signal but the other phones in the household (that are not i[hone 12) mare receiving a stronger signal than the Iphone 12. when i look up the db in the servicew menu, my iphone 12 never gets a signal better than -115db out in the open which is 2 bars and falls to -119 which is 1 bar in any typr of structure, which tells me that it is a device issue. the towers are sending a stronger signal than the iphone 12 is receiving.
