I get really frustrated when I hang around forums like xda-developers. Clearly, those guys know their stuff backwards and forwards, but to a guy like me who has less background in tech, they confuse the heck out of me most of the time. Max usually has a way of explaining things so’s I can unnerstand it (sorry Forrest).
Current phone is a GS9+ 965F/DS Exynos version. I didn’t understand when I bought it that I wouldn’t get Tmobile carrier features like WiFi calling which is really important to me as I have very poor cellular signal at work. The only solution I found so far is something called Detonator which is not a ROM but some sort of add-on, but it does require bootloader to be unlocked which I believe will trip Knox and make me lose Samsung Pay forever so I am waiting to see if a better solution comes along before I try that.
