Chosen Solution
I broke the tablet monitor and ordered digitizer+display on ebay. The seller made a mistake, so those parts were delivered separately. After I install it, I found the touch screen is totally inverted! It feels like the touch screen should turn 180 degree, but I can’t do that because the connection is fix at right top. There is one discussion about similar issue, but not solved yet. (x axis inverted on digitizer after replacement) I think the root cause is the model of digitizer is not match, but want to know if this can be fix by install the correct firmware or change the software setting? Symptom: the XY coordination on touch screen is opposite (rotate 180 degree) after digitizer replacement What I have done: factory resetsystem update (Android 7.0)developer options - didn’t see option to calibration touch screencan’t find touch screen calibration appcan’t find the product from the website of digitizer supplier Device information: ASUS ZenPad 10 (C300M)Hardware information - Touch panel version: 2.2.AA-1.2-5e7f2eSoftware information - Build number: NRD90M.WW_P00C-V5.3.6-20170412Digitizer supplier: Atmel, MXT1666T2-C2U
Well, first check your cable connecting to the PCB, then make sure you haven’t oriented the screen wrong lol… Yes, thats possible if the screen rotates with the way you are holding it
