My wifi drops in signal then I have to hit the top left corner lightly to get the signal strength back. This occurred after I carried out a screen replacement. I took it off and cleaned the antenna but I have had no luck…. wondering if anybody can help me.
It sounds like you may have damaged something in the antenna area when you replaced your screen. Open it up again and go through this guide to make sure everything is okay. I would focus on the iPhone 6 Logic Board Antenna Flex Cable and the WiFi Antenna.
