How To Fix Galaxy S3 Freezing Problems


Fixing Galaxy S3 freezing problems needs common sense because 95% of the time they’re not serious and often caused by apps and native services. Other reports also suggest that after months of usage, the phone turns real slow to the point that users couldn’t use it anymore because of lags and freezes.

I just want to make it clear that Galaxy S3 lags are different from freezes. However, these two are related because most of the time the phone lags first, then freezes forcing the user to reboot the device unnaturally. Here are some of the cases related to freezing in Galaxy S3.

Freezes Caused By TouchWiz UI

This is a common problem for Samsung smartphone users especially for devices that run on TouchWiz UI on top of the stock ROM. One way to know if freezes and lags were caused by TouchWiz is when the phone hardly responds to users commands. For example, if Galaxy S3 takes forever to unlock the screen or launch the messaging app or the browser. These operations are very light to execute but when the phone lags when instructed to do so, TouchWiz may be causing it. To fix it, you need to do the following:
  1. Go to Settings.
  2. Applications Manager
  3. Swipe left to choose All tab.
  4. Scroll down to and tap TW.
  5. Find Clear Data button and tap on it.
  6. Reboot the phone to refresh its memory.
  7. The freezing should be gone by now if it was caused by TouchWiz UI.
There were also some reports from users who have experienced infinite TouchWiz crashes. If this is your case, a Factory Reset is needed since you cannot already do something with the phone if the launcher fails to cooperate.

Freezes Caused By Security Apps

If your phone freezes randomly without apparent reason and you have a security app installed in your device, it is advisable you try to disable it first and see if the phone behaves differently when the service is not running.
  1. Go to Settings.
  2. Application Manager.
  3. Find the security app you’ve installed and tap on it.
  4. Touch Disable button to prevent it from running in the background.
  5. Try experimenting with your phone to see if there is a boost in performance minus the freezes. If it does, try looking for another security app to be installed in your phone.

Freezes Caused By Heavy Apps

If you’ve just downloaded and installed a considerably large (in size) and heavy app and your Galaxy S3 occasionally freezes after that, this is what you got to do to know if it’s really causing the problem.
  1. Go to Settings.
  2. Application Manager.
  3. Swipe twice to choose All tab.
  4. Find the app you just installed and tap on it.
  5. Tap on Disable button.
  6. See if there is a boost in performance after that. If there is, you may consider uninstalling the app from your device to maximize its performance.
It’s not really about how huge and heavy the apps are, more often, there are some inconsistencies that causes the freezing problem in the Galaxy S3.

Freezes Caused By Overheating

When the phone turns really hot after several hours of straight, extensive use, odds are it will enter into a boot loop as a fail-safe measure or it will freeze itself up when its processor is about to be fried. Here’s what you need to do when this happens:
  1. Try turning off the device using the typical way. If the phone does not respond at all, try pulling out the battery.
  2. Leave the device alone without a battery for several minutes until its temperature turns normal again.
  3. To prevent this from happening, give your phone a rest from time to time and don’t use it extensively while charging.

Freezes Without Apparent Cause

There are times when the Samsung Galaxy S3 freezes and you don’t know what caused it. This is what you should do:
  1. Try turning off the phone the typical way, if it doesn’t respond, take the battery out.
  2. Reinsert the battery and turn the device on again and see if it still freezes after that. Sometimes a phone does need to freshen up.
  3. If the problem happens most of the time, back up all your data.
  4. After the backup, turn the device off.
  5. Press and hold the Home button, the Volume Down button and Power button simultaneously until the Samsung logo appears.
  6. Using the volume keys, highlight the option wipe data/factory reset and press the power button.
  7. Scroll to Yes–delete all user data and press the power button once again.
  8. The phone will now wipe everything inside it including third-party apps.
  9. Once done, reboot the device and wait until it’s fully active before you use it.
  10. See if everything works the way they were.

I was having issues with random freezing and shutting off. I was using go launcher. After a factory reset/data wipe it was working ok, until I installed all my apps (minus go launcher). So it wasn't the launcher. A friend of mine was having a similar issue which he thought was caused by the facebook app. After a second reset/wipe I installed all my apps plus nova launcher (but without facebook). The issue has disappeared. Time for facebook to fix their shit!
