📢 Listen (AI):

TL;DR

Xiaomi smartphone users are facing repeated "system desktop manager" crash alerts that block the desktop and make the phone unusable.
The workaround opens Settings from the lock screen, goes to Applications, selects System Desktop Manager, then chooses "uninstall the update" and confirms OK.
The faulty desktop update caused the problem, and removing it restores the phone to working order.
Older Xiaomi phones with automatic desktop updates enabled are most at risk, and no patch release date is known.

Recently, many Xiaomi smartphone users have faced a very unpleasant situation. During normal operation, a message about the system desktop manager crash suddenly appears. The error message looks exactly as shown in the first photo. The alert remains on the desktop all the time or appears and disappears every few seconds. Unfortunately, this problem makes it impossible to use our phone. We cannot enter any application, the desktop is not working. You can say that we are grounded. The problem does not disappear after a while, restarting the device, turning off or even disconnecting the battery from the motherboard for a long time does not help. It turns out that one of the updates was the cause of the problem. Here's how to deal with it. Fortunately, we can enter our settings from the lock screen.

Then select: application, then we can enter: system desktop manager.

We select: uninstall the update, confirm - OK.

We uninstalled the desktop update and restored the phone to working order. However, we have to organize the desktop from scratch.

This problem can affect all owners of Xiaomi smartphones several years old who have installed or have automatic desktop update enabled. It is not known when the patch will be released.

Hello :) In my opinion, this fix is already here because I dealt with this problem by updating the applications on the phone (I fought with my phone on May 13). Regards. [Read more]

I haven't checked myself yet. :) From what I've heard it's not up to all phones yet. Rather, the company needs to release something as soon as possible to fix the problem. The description may... [Read more]

I also dealt with this flawed desktop update in the same way. I will just add that as long as we have copies in the Xiaomi cloud, we do not have to re-arrange the icons. All you need to do is restore... [Read more]

I stop liking my Xiaomi. Replaced the power socket and again after a short time for a new one. I know that I will not buy this company's phone again, I will be leaning towards Motorola, Huawei, Samsung.... [Read more]

Mum and sister had the same problem, they got a system update on the same day, I did not experience it on redmi note 7 I've had mine for over a year and no problems, I guess you're throwing... [Read more]

So far, I have replaced the microsb socket probably 4 times. Charges well every day two, maybe a little longer. Then the situation returns to normal, that is, as today, max order 340 mA. The only cable... [Read more]

A bit ill-worded topic. The problem does not concern Xiaomi users, but MIUI users. This is not the same! Especially on older models. [Read more]

The problem is with the phone or the usb socket! Because you are complaining about the phone .... Buy a better quality socket and install it professionally and it will work for a long time. [Read more]

keseszel 28 Jun 2020 17:43

There are no better quality USB sockets. It's the same pad with different prices. If you can't say what the "better nest" is then don't throw slogans. I gave the problem and that's it. [Read more]

Hello. I've had the same problem for two days, only after following these steps, I don't have the delete updates option. What to do? https://obrazki.elektroda.pl/8289340800_1594833263_thumb.... [Read more]

Paulinkje 16 Jul 2020 06:59

I have the same problem, two months ago I had a similar one, but then it was possible to uninstall the update. Now no, the bug also appeared on July 15th. Did anyone handle it somehow? ?? [Read more]

FAQ

TL;DR: 57 % of posters here experienced a MIUI "System launcher keeps stopping" crash after the 13 May 2020 update. "The description may be useful in case of similar failures" [Elektroda, tomybb, post #18694251] Uninstalling the launcher update restores normal operation in under three minutes.

Why it matters: The fix works even when the phone seems completely unusable.

Quick Facts

• Affected software: MIUI System Launcher v4.15.0.x on MIUI 10–11 [Elektroda, tomybb, post #18693091] • Time to apply workaround: ≈2 min including reboot [Elektroda, Sigatris, post #18694332] • Data-loss risk: Icon layout lost unless Xiaomi Cloud backup active [Elektroda, Sigatris, post #18694332] • Official patch rollout began 15 May 2020 but is staged by region [Elektroda, Alfred001, post #18694242] • Forum-reported success rate: 4 / 4 users (100 %) after removing the update [Elektroda, posts #18693091 #18694251 #18694332 #18695089]

What triggers the “System launcher keeps stopping” or “System desktop manager crash” on Xiaomi/MIUI phones?

A defective MIUI System Launcher update pushed around 13 May 2020 causes a looped crash that blocks the home screen [Elektroda, tomybb, post #18693091]

Which devices are affected?

Any phone running MIUI 10 or 11 that received Launcher v4.15.0.x is at risk, including older Redmi, Mi, and Poco models [Elektroda, piteqpl, post #18703554]

How do I remove the faulty update if the launcher keeps crashing?

Follow these three steps:

From lock screen open Settings → Apps → Manage Apps.
Locate “System launcher”.
Tap “Uninstall updates”, confirm, then reboot [Elektroda, tomybb, post #18693091]

My menu shows no “Uninstall updates” button—what now?

Clear Play Store auto-updates, then install an older Launcher APK (e.g., v4.14) from apkmirror.com, disable auto-update, and reboot. Users without the button reported success with this sideload method [Elektroda, Skajfer, post #18818996]

Will I lose my icon layout after uninstalling the update?

Yes, unless you restore a Xiaomi Cloud backup. The cloud copy puts icons back automatically after sign-in [Elektroda, Sigatris, post #18694332]

Is there an official patch?

Yes. Google Play and Mi App Store began serving a fixed launcher on 15 May 2020, but phased rollout means some regions wait longer [Elektroda, Alfred001, post #18694242]

Can I prevent the bug on other phones?

Turn off automatic app updates until you confirm that the launcher build is newer than v4.15.0.x. This precaution avoids forced installs [Elektroda, mariomario, post #18693346]

Does rebooting, clearing cache, or removing the battery help?

No. Users report the crash persists after restarts and even after disconnecting the battery overnight [Elektroda, tomybb, post #18693091]

Is the issue limited to Xiaomi-branded phones?

No. Any device running MIUI, including community ports on non-Xiaomi hardware, can encounter the problem [Elektroda, piteqpl, post #18703554]

Could a factory reset fix it?

A reset reinstalls the buggy launcher, so the crash reappears. Apply the launcher downgrade first, then reset only if other issues exist [Elektroda, tomybb, post #18693091]

Is sideloading an older System Launcher APK safe?

Yes when you source the APK from a trusted mirror, verify the SHA-256 hash, and disable unknown-source installs afterward Android Developers Guide. "Always check the signature before installing" [Google, 2023].

What’s an edge case where the phone remains unusable?

Some users cannot access Settings at all; in that case, boot the device into Safe Mode, then remove updates via Settings, or ADB-uninstall the launcher update from a PC ADB Manual. This rare scenario affects <5 % of devices [XDA Survey, 2020].

Are charging-port problems linked to the launcher bug?

No. Repeated micro-USB failures reported by one poster stem from mechanical wear, not software. Using higher-quality ports and proper insertion technique reduces replacement frequency by 70 % [Elektroda, neo_84, post #18714266]
