Only the bottom portion of the screen, where the 4 icons are located, is totally unresponsive/dead. Have cleaned the screen, with no improvement. Can't see any settings to change. HELP!
iPhone 4, iOS 7.1.2, This software is "Up to Date".
Has the device been restarted at least once since you noticed the issue? Has it been force restarted?
Restart your iPhone, iPad, or iPod touch - Apple Support
If a force restart doesn't help : Backup your data, then Use iTunes on your Mac or PC to restore your iPhone, iPad, or iPod to factory settings - Apple Support. After that, set up the device as new (not using the backup). Test the device. If it still presents the issue, it's a hardware issue. You can go to https://getsupport.apple.com/ and to learn which service options are available in your country.
I've had this happen to me with my iPhone 3gs. What caused it for me was water damage. I was told it could have been from even a drop of water or too much moisture in general. My phone was never dropped into or submerged in water. Had to get it replaced.
Thanks for your suggestions. Yes, did a couple re-starts, but no change. Have not done a re-set yet, but a local phonr repairer that I trust has said that it is a hardware issue, and the screen needs replacing; cost is £40 (GBP), which is a reasonable price over here. Will probably do this.
Yes, might be a water issue (phone is 7 to 8 years old). What is strange is that the rest of the screen is just fine; so, a rather weird situation.
Solution Found: I am going to have the screen replaced, as there is no software fix available.
