Hello! I have a replacement screen that looks great and intact. No issues with touch at all. However, once I put the iPad back into its case (STM, has magnets) and close the cover, Siri will trigger. Any suggestions?
There are two SmartCover magnets on the inside of the digitizer (see Step 49 - 52 of this guide). Did you migrate them over to the replacement screen? If so, it is possible they became dislodged or incorrectly positioned.
