I now have the G 4G on T-mobile after have 6 replacements with the Samsung Vibrant for the same issue. Its sad that this phone did not as far to fix those issues and I'm not exactly sure why. As you can imagine, I've talked to every technical "expert" at Tmo and Samsung and boy they all have the same reaction, "really gps is not working" and "oh, I have no problem with bluetooth". seriously people. Had this phone for 3 weeks not and here are my problems:
1. Performance - Phone is very choppy to navigating screens. Once apps are loaded to the device this issue is more exaggerated.
2. For what ever reason, this phone, as did the vibrant, is constantly vibrating. I have no idea of what its doing.
3. Bluetooth - My primary concern since I live in a hands free state - is bad and that's putting it mildly. I've gone through 4 headsets (motorolla, plantronics, even one from samsung recommended and t-mobile store one) Bluetooth will connect when phone is reset to factory - but after first phone call hang up, will not connect. Does say it's paird (same exact problem I had with the Vibrant). Sometimes after about 10 or more times turning off and on of BT, it will finally connect. What a pain.
4. Freezing - the Vibrant did not even have this problem. From the first day, this phone not only has been choppy in performance, but when I've got the phone in a dock (home or car), the darn thing freezes. Now, funny thing is, if i wait for 30 minutes (Yes that's right 30 minutes or more) it will respond and it's doing a crap load of vibrating the whole time. I just pull the battery instead.
I understand that those that have loaded one of the other ROMs seem to be happy as many of these issues may have been fixed or have some form of work-around. I can't afford to do that, this is business and personal and I must have a phone that stays in warranty. So, I will continue to hound Tmo and Samsung, probably go through another 5 or 6 of these at $20 replacement fee and get the next model to see if these issues are fixed and I finally get a phone that does what they advertise.
Yes its lovely and all that with the 4 inch screen, but functionally and performance wise in it's OEM form, its a piece of crap as was its predecessor. So don't jump on me for wanting the OEM/carrier to stand behind their products and deliver on their false advertisement. Instead of saying its a smart phone, they should say, use at your own risk.
Just venting!!
