Huawei Mate 20 X July update reportedly fixes EMUI 9.1-triggered crashes/reboots & audio issues

EMUI 9.1 update on one of the Huawei Mate 20 lineup devices, Mate 20 X, left users complaining. For a quick refresher, Android Pie based EMUI 9.1 was rolled out to Mate 20 series – including Mate 20, Mate 20 X and Mate 20 Pro – by the end of June.

The key highlights of the update (v9.1.0.300) were inclusion of features like Moon mode for enhanced photography, GPU Turbo 3.0 for better gaming experience, EROFS technology for improved system performance and stability, video ringtones for specific contacts and one-touch music videos.

EMUI 9.1 on Huawei Mate 20 X

While Mate 20 series users were happy on EMUI 9.1’s advent, Huawei Mate 20 X users began reporting random app and device crashes/reboots, which left their units barely usable.

While some said apps randomly crash and then prompts them to enter the PIN to unlock the device, others reported the OS itself crashes (lead to a black screen) followed by the PIN code unlock screen. Take a look at how some of the complainants word the issue across different discussion platforms:

Sometimes chrome some time other apps are crashing after using a minute or more and then OS crash and display goes black and lock the screen then I have to unlock again.

I experienced a lot of problems with the latest Emu 9.1 patched version. My phone basically got crazy. It was rebooting, apps crashing. Phone taking me to home screen and asking me to enter the pin, the phone was asking me to give it access to my location to update the time.

My phone is practically unusable. Some apps (random – not the same app) not opening. Not even the camera or gallery open. The phone keeps going to black screen when I try to use it. After around 5 seconds I am and taken to the home screen and am requested to enter my pin.

Apart from crashes, users also reported poor playback media audio. Despite the crash/reboot and audio problems being reported for over a month, nothing much was done to address the issues, at least until now and complaints kept proliferating.

But that changes now. Huawei Mate 20 X is now receiving a new big update that weighs about 4GB and reportedly resolves the crash and audio problems instigated by the first EMUI 9.1 build. The update bumps the build from to and brings along the July security patch.

The patch is currently being circulated on the European region units of Mate 20 X. 


Following are reports from some of the users who received this new patch, confirmed the issues in the first EMUI 9.1 update have been taken care of in this new build. does fix the random crash and low and crapy media playback audio issues! The media playback audio is as awesome as it should be now.

Finished setting up all my Apps and phone. It is problem-free!

No doubt that 9.10.310 has restored the awesome audio quality and loudness in media playbacks for Mate 20X! …. and YES! No crash!

Those of you who were encountering crashes and playback audio problems after EMUI 9.1 update, give the July update a try. Not to miss, as firmware updates are rolled out in batches, this patch may also take time to reach all the units. And yes, don’t forget to share with us how it goes.
