All iPhone 4s suffer from this...you just dont know it yet!
Problem: The iPhone 4 currently cannot maintain a Bluetooth signal while listing to music when the phone is in your pants pocket. Simply put, you can’t even go for a walk with your phone and listen to music via Bluetooth headset.
Hardware used for testing
6 different IPhones 4/4.1 (ranging from purchases made on launch day in Canada till oct 15th)
Various iPhone 3GS
Plantronics Backbeat 903/906
Motorola Rokr S9 HD
Blue Ant T1
How to test your iPhone 4
1. turn on Bluetooth headset
2. turn shuffle off in iPod settings (Settings - iPod - Shake to Shuffle - OFF)
3. play a song
4. verify that you can hear the music playing in your headset
5. put your iPhone 4 in the front pocket of your pants or shorts, screen facing leg.
6.Go for a 5 min jog outside (happens much more frequently outside). If youre not a jogger then a walk around the block will trigger it.
Basically it sounds like a CD skipping and progressively gets worse. Therefore anyone that goes for a walk or anything athletic cannot listen to music via Bluetooth headsets on. Being able to work out and listen to headsets with no wires is priceless, this phone cannot do that. Without this functionality working it becomes a worthless phone.
The kind of good news is if you own a 3GS or Blackberry it works great. 50 feet away at least. Or in your pocket while running, walking, full cardio training etc. very clear and never skipped once.
Hint: it has something to do with the screen. We did all of the testing with the screen completely covered in various cases and we tried the phone with cases that had nothing covering the screen and no case at all. When the screen is in closed in a case or held in hand by its edges it works fine. With the screen exposed whether using a thin protective screen or not the problem happens.
Note: all of the iPhones 4 were completely reset. One of the iPhone 4’s we tested was never setup to be a phone, it was just used to play music. All failed the test. All other phones passed.
Perhaps the beta testers were all couch potatoes’ …
Intel Quad core 3.2 Windows 7 64 bit, all working very well
