Answer to "How do you fix the iPhone 7 ghost touch issue after screen replacement"I had also this problem with my two iPhone 5s after two weeks from screen replacement. "Makabu-ang ni nga problema" because it even automatically deletes texts when you're typing for messages. Let me share this with you of what I did. 1.) Removed my existing screen protector and cleaned the touchscreen. 2.) Temporarily attached clear scotch tape on my iPhone's screen. Overlapping is ok for testing. 3.) Performed testing and problem is gone. 4.)Removed clear scotch tape and replaced with new screen protector [tempered glass]. That's all and maybe it helps a little to solve your problem. To God be the Glory.., all the time!
