iPhone juddery / laggy after screen replacement
I already replaced a lot of LCD’s (no iPhone 7’s) and never had any issue.
Now I had an iPhone 7 to repair (screen replacement) and ordered a china display.
After replacing the screen, I noticed that the iPhone performance (ios 11.4.1 - latest one) is not the same as it was before. It’s not that bad but the difference between before and not is obvious. The phone doesn’t crash or doesn’t need long to open apps, or the performance is not 1sec behind as some people complain. It’s just working little bit slower (juddery).
I would like to know if this issue is related to the china display or if I broke something during replacing the display?
Unforutnately I don’t have the original display, otherwise I would have tried it.
Finally I ordered another Display from Amazon that has a 5 Star revision (120 revisions). This one is better as the one before. It’s kind of faster but still not as fast as an original Display.
Has anyone did the same experience or has the same issue?
Thanks in advance.
This evening I will upload a Video to show you guys exactely what the issue is.
