Have you recently had your iPhone 7 Plus screen replaced? If so, have you been experiencing screen lag? This is a really common problem with the iPhone 7 Plus after a screen replacement. The cause of this issue is because there is such a heavy demand for iPhone’s, Apple needs to outsource the manufacturing of its LCD screens to multiple factories to make enough to meet the demand. Each manufacturer gives the LCD a code to identify which manufacturer it is from. On the iPhone 7 Plus it is very important to make sure you match the code from the original LCD that came on the phone when it was brand new. This will ensure that you do not run into the laggy touch issue.
The current LCD manufacturers for Apple are Sharp, Toshiba and LG. Only Toshiba and LG make the iPhone 7 Plus screens. For Toshiba, the codes on the LCD’s are C11 and F7C. These codes are interchangeable, meaning you can use C11 on a phone that came originally with F7C. LG uses the codes DTP and C3F. These are the two you need to be very careful with. If the phone originally comes with the code DTP you must always use a DTP screen when replacing it otherwise you will almost certainly run into some touch issues when reassembled. DTP is probably the most versatile out of all of them as it can be used on most iPhone 7+ without any touch issues. You get the most amount of issues when using other codes on a phone that originally came with a DTP screen.
