How to Resolve Redmi Note 12 Screen Freezing and Crashing

Redmi Note 12 Screen Freezing and Crashing

Experiencing annoying screen freezes or app crashes on your Redmi Note 12? This frustrating problem is often caused by software bugs, overheating, excessive memory usage, storage issues, or system conflicts after an OS update. Don’t panic – with some diligent troubleshooting, you can get your Redmi Note 12 working smoothly again.

Redmi Note 12 Screen Freezing

Common triggers leading to screen freezing and app crashes include:

  • Buggy system software needing update or restore.
  • Too many apps running simultaneously overloading RAM.
  • Overheating causing the system to lag and freeze.
  • Low storage space causing performance problems.
  • Incompatible or problematic third-party apps.
  • Issues with system files after an OS update.

Here are effective solutions to try when dealing with screen freezing or app crashes on the Redmi Note 12:

Close Background Apps

Free up RAM and system resources by closing any apps running in the background that you aren’t using.

Too many apps occupying RAM can lead to insufficient memory for the system to run properly, resulting in freezes or crashes. Closing unused apps frees up valuable system resources.

To close apps:

  1. Swipe up from the bottom of the screen to view recent apps.
  2. Swipe left or right to browse all open apps.
  3. Tap the X icon on each app window to close it.
  4. Clear all apps when done – this will free up RAM and processor usage.

Check for Overheating

Excessive heat buildup within the phone can slow down the processor, causing temporary freezes.

Inspect your Redmi Note 12 for hot spots near the processor which can cause throttling and performance issues leading to crashes.

To check for overheating:

  1. Open the phone case and carefully feel along the internal components.
  2. Pay attention near the processor for abnormal heat.
  3. If any concerning hot spots are found, power down the device to cool internally.

Update Software

Install the latest OTA updates, which may contain critical patches and bug fixes.

Outdated system software can harbor bugs that interfere with performance and cause freezing issues. Updating provides optimizations.

To update:

  1. Go to Settings > About Device > System Updates.
  2. Follow the prompts to download and install any pending OTA updates.
  3. Restart your device once the installation completes.

Following these steps should help isolate and resolve any screen freezing or crashing problems on your Redmi Note 12. Be sure to monitor your device’s temperature, available storage, and RAM usage as well.


  1. Q: Why does my phone screen keep freezing and apps keep crashing?

    A: Frequent screen freezing and app crashing is typically caused by outdated software needing updates, insufficient RAM and storage space, overheating from excessive processing load, buggy apps, and system file errors after an OS update. Updating software, closing background apps, clearing caches, factory resetting, upgrading RAM/storage, and preventing overheating can help.

  2. Q: Why does my phone freeze and crash even after a factory reset?

    A: If freezing persists after a factory reset, the issue is likely hardware-related. Possible causes are failing RAM/storage chips, overheating processor/motherboard components, faulty display connectors, bad logic boards, and damage from drops or liquid. Try cleaning dust to prevent overheating. If not fixed, visit a repair center to determine and replace any faulty hardware causing unresolvable freezing.
