I just had a similar issue with my iPhone 6, searching and no service most of the time and if I get a signal eventually it only shows 3G (it should be 4G) and there is no data coming trough (works fine on WiFi). What I did is I replaced QFE1100 (the signal power ic) which was corroded due to water damage and now my phone works fine, I have 4G and I have SIM data. Could be the Baseband IC as well, you should reball or at least reflow it. Hope this helps someone :)

Hi, I have a similar issue and I hope someone can enlighten me on this matter. https://youtu.be/GuPwaGTbS3s So basically my problem is that when I need to remove and replace the polarizer film on the iPhone 6 (mainly), the screen starts to get purple when and where you touch it... I use copy polarizer films, but I do add the silver conductive paste at the top (I also use OCA and 5 in 1 vauum laminator machine). The problem appears once every 5 to 10 screens maybe, but it is very annoying and no matter how many times I redo the acreen I can't seem to find a way to get rid of it. Any suggestions, is it poor quality polarizer film or something else? Thanks
