How to Fix Xiaomi Speaker Not Working or Crackling

A Xiaomi phone stuck on the “Optimizing App” screen is usually caused by corrupted app cache, a failed system update, low storage, or an app conflict during startup. The fastest fixes are a forced restart, charging the device, clearing cache from Recovery mode, uninstalling recently added apps in Safe mode, or updating MIUI after the phone boots normally.

Steps

Force restart the Xiaomi phone. Hold the Power button for about 10–15 seconds until the device reboots. A temporary startup bug can trigger a Xiaomi optimizing app loop.
Charge the device and wait 10–20 minutes. Low battery can interrupt app optimization and cause stuck optimizing Xiaomi errors. Keep the phone connected to a stable charger during boot.
Boot into Recovery mode and wipe cache if available. Power off the device. Press Power + Volume Up to enter Recovery mode. Clear cache or temporary files if the menu offers the option, then reboot.
Start in Safe mode and remove problem apps. If the phone boots, uninstall recently installed apps, battery savers, cleaners, or modified launchers. Faulty apps often trigger the fix optimizing screen issue after reboot.
Update or reset the system only if other methods fail. Install pending MIUI updates after normal boot. If the loop continues, a factory reset may be necessary, but stored data can be erased.

Common Issues and Fixes

Issue	Likely Cause	Fix
Phone keeps returning to “Optimizing App” after every reboot	Damaged app data or incompatible app update	Uninstall recent apps and clear app cache in Safe mode
Optimization screen freezes for a long time	Low free storage	Free storage after boot or use Recovery tools if the system allows cleanup
Problem started after MIUI update	Incomplete firmware installation	Reboot into Recovery mode and install the latest stable update if available
Only one app appears to be optimizing repeatedly	Corrupted app package	Uninstall and reinstall the affected app after the phone starts
Phone cannot pass the startup screen at all	Deeper system corruption	Use Recovery mode, then consider factory reset as the last option

Quick Tips

First boot after a major MIUI update: It can take longer than normal. Waiting 10–15 minutes once is reasonable before forcing another restart.
Low storage warning: Storage that is nearly full can cause repeated optimization loops. Less than 1–2 GB of free space is a common trigger.
Cache clearing is not always enough: Repeated cache clearing may not help if the problem is caused by one broken app. App removal is often more effective.
Factory reset caution: A factory reset usually fixes severe stuck optimizing Xiaomi cases, but local files and app data may be lost without backup.

🤔Note:

If your Xiaomi phone is optimizing apps after a major MIUI update, one long startup is not always abnormal. Let the phone sit for 10–15 minutes on the first boot before trying another forced restart.

Why does a Xiaomi phone say “Optimizing App” on every startup?

The message usually appears when Android is rebuilding app data after an update, crash, or cache problem. If it happens every boot, one app or system file is often damaged.

Can a factory reset fix a Xiaomi optimizing app loop?

Yes. A factory reset can remove corrupted app and system data. Data loss is the main limitation, so backup matters before using that option.

💡Protip:

If the phone eventually boots but remains unstable, a device management tool such as Dr.Fone can help back up important files before deeper repair steps or a reset.
