Bought new Cappy from US for use in OZ. Unlocked then rooted with one click. If your "use data packets" is not on, your phone will do a disco if a call trys to get through- vibrate, turn on and off etc. Since mine did it i have no carrier id or Edge or 3g signifiers in the notification bar besides signals strength. I had to restart phone to stop it. Actually wouldn't stop- 25 minutes.I had to pull out the battery. Repeated process to check effect.
Have no sound now in or out on calls, in or out going. don't know how many calls i've missed.I live alone with a terminal heart condition,have elderly and diabetics in the family. I read that may be because of non samsung earphones being used and switching matters. I have not used bluetooth etc only song vids and mp3's.
Also read that phone with the same problem works on bluetooth but not on it's own like switching is effected.
My troubles may be clash of carriers. Our carrier here loves playing with your freedom and inside your phone for it's benefit as much as AT&T.
Volume also goes up and down of it's accord.
If i can't sort this out and get rid of AT&T's bloat and fiddlings i will use it as a wifi tab. There seems to be way tooooo much trouble with apps, roms and samsung and carriers. Non of them match their claims or advertising.
Some choices. Some people have luck and land on their feet with them.
I loved it when it worked for a couple of days but have spent over 60 hours on the web in a matter of weeks trying to sort and search things and learn and 5 all nighters searching and reading. Everything conflicts and a risk taking the advice of strangers. Plenty out there think it's a joke to brick someones phone and any fix seems to cause a chain reaction of other.
I bought 8 SSB radio sets for my family. I'm over carriers, manufacturers,brush offs ,lies,false advertising and gouging. All supported by our governments.
Does anyone know of a manual for these time wasting drink coasters?
