I use a 8900 for tmobile and i came from the stock 4.6 preloaded os on it. i noticed that on OS 5.0.0.822, ive been getting more failed calls... i'd be talking on the phone and during my conversation, it would do that a few times and its frustrating D: my wifi is always on but i dont use wifi to make calls, although when my calls fail, sometimes it says "call failed:wifi signal lost". is there a another build of 5.0 that i can load? and how to prevent that wifi problem without disabling wifi

sometimes my phone doesnt ring on profiles where it would usually ring so i have to do a battery pull =_= please help me
