You will most probably find that Andriod 11 don't release that AP, since it picks up enough power from that AP even though you are to a closer AP.
Might need to play with the M5 power output so that it changed to the next available AP.
Well looking into getting the 9T. Been a Samsung Note series boy for a while now, but really don't see the point in paying thousands of Rands for a phone where I don't use half of the features.
My only requirement is the size. I've got big hands and the Note series has always been perfect. So comparing the size, the 9T and my current Note 8 is the same size about.
I see Incredible Corruption has it for R 3699 (
