I am looking for some help and advise here.
I have GPS working very well with aGPS enabled. I can get lock within seconds which is a very good sign.
Recently I was driving with bluetooth On on my TP and the satellite lock was constantly disapearing. What I mean I can see the lock is happening and then after one second it's gone. Few seconds later it happens again.
Is it something new or the problem is known and what is more important can it be fixed?
I appreciate any help here.
