Touch is not working after March update in Max Pro M2

[Alankar]

When I boughg new Asus Zenfone Max Pro M2 phone there was touch issue.
I requested for return on flipkart but they sent technician and he just reset the phone. Again next day touch problem occurred and technician did the same again. This return and reset process continued 5 times i.e. I put the return request on flipkart 5 times but they didn't approved the return. Meanwhile I got the next Software update on my phone and phone worked till March( When the warranty period expired). But after March update the touch problem started again. It lasted for 2 days and started working automatically. But after around 10 days the same problem occurred again. This time it didn't get resolved automatically. Then I did factory reset, no benefit of this....then I downgraded to WW_Phone_16.2017.1912.072 from WW_Phone_16.2017.1912.092
But no gain...touch is still not working ...now I installed anothet version i.e. Android 10 beta version from official Asus website. Touch still not working.
I decided to downgrade it to the earlier version i.e. WW_Phone_16.2017.1912.072
But it showed error
E3304: This package is for ASUS_X01BD devices. This is X01BD device.
Now I changed the code where it check the Device Model. It is available in Updater script file. And installed the framework WW_Phone_16.2017.1912.072 using TWRP recovery. This time touch started working.
Please tell me what is the exact problem behind this touch issue.
And please fix it in new firmware update and release as soon as possible.

Hi mukesh_mehra1
Thank you for your reply. Kindly refer to the reply as below
1. For an user having the knowledge of performing "Root Integrity Check", I can not guarantee your usage behavior is as same as Pulakesh or other users. You may possibly trigger some process similar to unlock or root behavior. For an usage behavior as a ordinary user, the Factory Reset and SMMI test can assist me and the repair center to diagnose the big picture of the issue.
2. If you still need any assistance next time, as I mentioned above, I may need your logs for further checking after I confirm some essential information. Always willing to help.

It is not rocket science or user familiarity on "Root Integrity Check". It's given in the 'Recovery Menu' of ASUS Zenfone Max Pro M2, Android 9. One has to just select and wait for results.
Your point 2 says for further help, you may require logs for further checking, it's not clear what kind of logs? You asked for screenshot for SMMI test result for Display, which I sent, also with Touch test, which both were positive.
Let's be fair, ultimate reply from you would have been to take it to ASUS service.

Hi,
Its not proper to say "Not even one user reported issue of un-responsive screen" after update. I also had same issue on m2 and It started after march security patch update. Even visited service center. They checked and downgraded the android update to 8 and told me to not update to pie version for 1-2 months. After 3-4 months I updated to pie as an update notification always pops up in between any thing on daily basis, and hell ! screen again stopped working out of sudden. It's surprising that Asus is not aware about issue, while I am writing about the issue and explaining it customer service executive for last 6 months .
And yes I tried everything-
Safe mode
Hard reset
Downgrade
Upgrade.
Cache wipe
Still problem persists, at the time of writing of this comment, my phone is ON, Charged , Recharged, Full On Network, Finger Print Unlock working, but I am not able to use it because of a fault of yours for which we paid and suffered.
