Yes, I used to have the Samsung Galaxy S and I had the same issues. I returned that phone and got the GX2. Well, guess what? I'm having the same issue. So, I dont know what is it now? does the problem present with all androids worldwide or just with T-mobile.
While I owned the Galaxy S; I called tech support with T-mobile and they could not figure it out then they gave me the tech support phone number with Samsung. Well, I called Samsung and after 10 minutes they transfered my call to Level 3 technical support. Well, after 15 minutes they did not know what cause it. They (tech support) suggested me to download an e-mail aplication (droid mail) to get what I want. HEELLOOO!!!
So, at this point I dont know if this issue is happening with all androids phones or what?.
I left Iphone to try android and I really regreted!!! I coming back with apple. Sorry for all of you that Loves Android, but Android (in my experiense) su...........!!!
Now, if anybody out there knows how to fix this issue please let us know!!!
