I lost the Auto—Brightness option after I replaced my iPhone screen. I was told to purchase a special programming device which I did. (JC-V1S) The programmer will read and write consistently to the original screen that came with my iPhone but will not read nor write to the iFixit replacement screens. I can consistently hook up the original screen and it reads the data every single time but now two attempted iFixit screens indicate they are connected but return no data. And when I attempt to write the data from the old screen to the new screens they go through the write process but will not pass verification. If I perform the same steps with an original screen it writes and immediately validates the data without error. Is this a know issue with your screens? Has anyone had this problem?
This might be because of an error when transferring the camera component between screens, to be clear you’re not getting any readings on the replacement screen after transferring the component and then getting a reading with the original and same component right? just making sure because the first place i can see you going wrong is improperly installing that component on the screen which I’ve seen before.
