Iphone 4’s innovative technology to use the stainless steel edges as antenna has proved to be a technical glitch. Iphone 4 users reported trouble with frequent call drops while holding their iphone 4 in a certain way. Tech Guru’s call it the “Death Grip” . While that seems like it’s mainly a hardware issue with iphone4 , others had found that their older iPhones that had updated to iOS 4 had the same problem.
If you hold the iphone in a slightly sweaty hand, with fingers covering the black lines on the iphone’s edge and the bottom left corner , signal strength is reduced.
- Avoid holding the iphone on the left hand corner
- Use iphone cases for protection.
- Use cheap hand bands made of rubber and cover the sides as shown in the picture below.
