28-6-19, 08:17 PM:- Finally I am able to fix my Mate 20 X. May be I find the solution and the cause of this problem but not sure.

1.

After updating Emui 9.1 and debloat my Mate 20 X with this post "https://xdaforums.com/mate-20-x/development/debloat-huawei-mate-20x-one-click-1-1-t3883921" when debloated my device, may be a file disabled which is necessary for emui 9.1. After a factory reset maybe the problem fixed.

or

2. I reinstalled the emui 9.1 on my device again by eRecovery and then fixed the problem.

Any of these fix my Mate 20 X. Thanks

01-07-2019: You don't have to downgrade by only FunkyHuawei. You an always easily downgrade 9.1 to 9.0 by HiSuite application which is free on windows. Whenever you open HiSuite application on windows there is an option to downgrade to 9.0 under update section.

11-7-2019:- Today an update popup I don't know what kind of update it is because in the Emui version there is no change but came a update and unfortunately I can not read the update text I just press the install button and install the update I think some kind of "Patch" word written there in update popup.

So waiting and observing what is that update actually

20-7-19: After a lot of experiment my mate 20 x now crash free. So what I have tried?

I downgraded Emui 9.1 to 9.0 then update again more than 4 times but crash issue not solved.

I tried possibly every single steps, but crash issue did not solved. download the update over the wifi, then downgrade and again update over the mobile network then downgrade and then update again by eRecovery but all the steps were just waste of time crash issue was not solved. Then I downgrade again and then do factory reset, clear cache memory then update again. Most probably 4 to 5 times I downgrade and update again my Mate 20 X to solve the crash issue but the crash issue didn’t solve at all randomly happened crash issues 5 to 10 times a day. Then I was totally frustrated and decided not to try to fix the issue, I was only waiting som day huawei will fixed the crash issue by any update or patch.

But day before yesterday I was totally disturbed by the crash issue and finally decided I will downgrade again and I will not update my Mate 20 X again before Android Q stable come for device. And after downgrade I have a though that to try the 9.1 update last with HiSuite pc apps then I tried to update Emui 9.1 again with HiSuite PC application and after update came a 11mb patch update I do all the update and fortunately after Emui 9.1 updated via Windows PC HiSuite app my mate 20 x get rid of the crash issue. Now no crash issue in my Mate 20 X.

22-7-19: I was totally wrong. After 5 days running without crash my Mate 20 X crashing again from last night. After 10-30 minutes it is crashing even I don't use the phone then also it is crashing randomly after certain period. So from today morning I have to downgrade again from 9.1 to 9.0.
