iPhone 4

5431657055_77c6407031_oIn 2010, the iPhone 4 offered the biggest leap since the iPhone with the introduction of FaceTime Video calling and Retina display. Improvements included a slimmer, redesigned case, a 5 MP camera with LED flash, a VGA-quality front-facing camera, and a stunning new 960×640 LED-backlit display. This phone was the first phone to include a front facing camera, and the first to be released in a version for CDMA networks. The phone was a big hit, but it had its issues:

  • Apple’s new, external antenna design, turned out to have a weak point when the signal was low. If you put your finger on the juncture at the bottom left, you could detune it and lessen reception by a couple of bars. If all you had were a couple of bars or less, you could kill reception completely. But since removing the finger or insulating the juncture with a case, returned the iPhone to normal working order, it didn’t matter.
  • Rear camera stops working – Users of the iPhone 4 have complained that while trying to take a picture, the virtual shutter on the camera is stuck shut. They have also noticed that, even if it worked properly later, they have found that it stops functioning permanently at some point.

  o Remedy: It’s no use trying to reboot or restore. That solution has never worked for any of the users that have tried it. Just look for a free time to take the iPhone to the Apple Store.

  • Rear camera white balance doesn’t work – With a 5MP camera, you can getIPhone_4_cameras amazing outdoor shots with the iPhone 4. Even the quality of the HD Video taken outdoors is as good as those shown in music videos. But when used indoors, the camera does not pass muster. Many users have reported that faulty automatic white balance causes many low-light shots to take on an extremely yellow cast.

o  Solution: Currently there is no solution. Maybe a future update can solve the problem.

  • Some users reported a yellow discoloration of the screen that disappeared after several days. This was attributed to the glass lamination glue that was used while manufacturing. Due to the high demand the phone did not have time to dry fully before the unit reached consumers.
  • Another issue reported by some users within days of the iPhone 4 release was that during calls the proximity sensor can be insensitive, so that facial contact with the touchscreen can end calls, mute calls, and dial other numbers.
