Why Is My Phone Glitching

Is your phone glitching? You'll have a tough time using the device until you address whatever's making it act up, whether it's software conflicts, cache corruption, or insufficient storage. However, there's another potential culprit—spyware. Download Clario Anti Spy immediately and run an Anti Spy scan to check your iPhone or Android for spy tools, stalkerware, and malicious apps.

Possible reasons why your phone keeps glitching

Your phone keeps glitching because you have too many programs open. It could also be you're using the device in a way that's causing it to overheat or have little to no free space remaining. Unoptimized software, malicious apps, and damaged hardware are other reasons that can make your phone behave erratically.

1. Too many programs open

iOS and Android allow you to open and switch between multiple programs easily. But the older your phone gets, the harder it becomes for the system software to keep up with the processing power and memory demands of newer apps. Too many programs open and running in the background could put a strain on system resources and cause slowdowns and freezes.

2. Phone overheating

Resource-intensive activities can overheat your phone, forcing the device to slow down or hard reboot itself to prevent damage to the internal components.

 

Apps that make your phone overheat include:

  • Graphically demanding video games
  • Unoptimized or outdated applications
  • Apps that continually ping location services
  • Monitoring tools that continuously work in the background to track your activity

Did you know?

If your phone is constantly overheating, someone could be spying on you. Learn how to tell if your phone is being tracked.

3. Most of the device's storage is occupied

Just because you have free storage on your phone doesn't mean you should fill it all up. Both iOS and Android require at least five gigabytes of space to cache data that can't fit into memory. If the storage is full, the system software has to constantly juggle whatever little space it has to make things work, leading to performance issues.

4. Problem programs

Not everything you download from the App Store or the Play Store runs smoothly. Some don't receive new updates, which means they don't work well with newer system software and phone models, while others are just unoptimized with bad programming. These apps can result in multiple glitches on your phone due to software conflicts, memory leaks, and overheating issues.

5. Malicious software or viruses

Yes, phones can get viruses. Fake apps regularly sneak their way onto the official app stores, so it's not unusual to accidentally install something malicious. If you have a habit of sideloading apps, you have an even higher chance of downloading privacy-invasive software. To make matters worse, someone close to you, such as a jealous partner, could install monitoring tools to spy on you.

 

Malicious software and viruses work overtime to collect data by hijacking core system software functions—e.g., location services. This, in turn, triggers a constant barrage of glitches on your phone.

 

Symptoms of viruses and spyware include:

  • A phone that's always overheating
  • Rapid battery drain
  • Unusual status symbols
  • Increase in data usage
  • Signs your phone is tapped—e.g., weird noises during phone calls
  • Unusual permission requests
  • Coded text messages

Pro tip

If you notice at least two of the symptoms listed above, chances are someone is spying on you using spyware. Get Clario Anti Spy to scan for spyware on your devices.

6. Physical damage

Dropping your phone on a hard surface can damage the hardware inside, preventing it from working correctly. Submerging the device in water—even if it's water resistant—could cause damage by moisture.

 

In that case, your best option is to have it professionally repaired. Unless you have extended protection (like AppleCare+ for the iPhone), most manufacturers do not cover physical damage under standard warranties.

How to fix phone glitching

There are various ways to fix a glitched phone. These involve restarting your mobile device, closing unnecessary programs and processes, and updating the system software. Other fixes include freeing up storage, booting the phone into safe mode, and checking for spyware. If all else fails, you should factory reset your phone.

1. Restart your phone

A system reboot clears the memory and resolves many unexpected technical issues that cause phone glitches. If you haven't already, try this:

Here's how to force-quit apps on iOS and Android:

  1. Open your phone's app switcher.
  2. Drag an app up and out of the screen to remove it from memory.

Pro tip:

Most Android phones allow you to extend your free space with a microSD card—invest in one to give yourself more flexibility and control over your data.

5. Booting the phone into safe mode

Safe Mode on Android devices automatically clears your phone's system cache, prevents third-party apps from loading, and lets you identify potential conflicts.

 

Here's how to boot your Android in and out of Safe Mode:

  1. Open your phone's Power menu.
  2. Long-press the Restart icon and tap OK on the "Reboot to safe mode" pop-up.
  3. In Safe Mode, perform any actions you couldn't do before, like updating the system software or freeing up storage. Once you're done, reboot the device normally.

Steps 1-3: Open the Power menu, long-press the Restart icon, and tap OK.

If you did not have issues in Safe Mode but your phone keeps glitching when you boot out of it, try deleting any recently installed apps and check if that makes a difference.

6. Check your phone for viruses and spyware

If the problem persists, you must check your phone for viruses and spyware. Go through the list of apps under Settings > iPhone Storage (iPhone) or Settings > Apps on (Android) and remove anything unusual. But a better—and safer—approach is to scan your phone with a reputed anti-spyware utility.

 

Clario Anti Spy is a security solution for iOS and Android devices. Its Spyware scan feature can quickly detect if your phone has hidden spy tools, monitoring apps, and other privacy-invasive software.

8. Clear the application cache

Most apps cache temporary files to speed things up, but obsolete or corrupt data can cause performance issues. If the glitches on your phone are isolated to a specific app, try clearing its cache. If you're on an iPhone, check within the app for an option to clear the cache—if you can't find one, offload and reinstall the app. On Android, you can clear the cache of any application via the Settings app.

 

Here's how to offload and clear an app cache on iPhone:

  1. Open the Settings app.
  2. Go to General > iPhone Storage.

9. Factory reset your phone

If your phone keeps glitching despite working on the fixes above, it's time to factory reset it. The procedure wipes your personal data, removes third-party apps, and restores all settings to their defaults. Back up your data to iCloud, Google Drive, or a computer so you can get back everything afterward.

 

Here's how to factory reset your iPhone:

  1. Open the Settings app.
  2. Go to General > Transfer or Reset iPhone.
  3. Tap Erase All Data and Settings.

Conclusion

Glitches on a phone can crop up anytime.
