Unbelievably frustrating experience with my 7 plus. My problem started about a week after installing 10.0.2. Didn't notice any problems until then, but for the last two weeks the phone goes to Edge in places it was reliably 4G with my SE and 6. It only seems to get 4G in VERY specific locations e.g. by a window at the top of my house or right by a mast near work. If I move literally 1 foot in any direction from those spots it stops loading data.
3G doesn't load data either, even when it shows full bars.
So far I've upgraded to all 4 betas, and down to 10.0.3 and I'm not seeing any improvement.
Aaaaaaaaaaaarrrrrrrggghhhhhhhh!!!!
