How to troubleshoot a Samsung Galaxy S5 that constantly freezes and lags & other performance issues

In this post, I will tackle the most common performance issues with the Samsung Galaxy S5 (#Samsung #GalaxyS5) like freezes, lags, and sluggishness. Anyone may encounter any of these issues because they come with the age of the phone. Needless to say, the older the phone, the slower it becomes.

There are, however, other factors that may lead to any of these performance issues like physical and liquid damage, hardware problem, firmware glitch, and app crashes. It is important that you observe your phone closely if you noticed that its performance deteriorated. Knowing the cause is the key to fixing the problem. Read on to know more of these issues and learn how to tackle them.

If you are trying to find a solution for a different problem, visit our Galaxy S5 troubleshooting page and look for issues related to yours. You may try the solutions we already provided and if they won’t work for you, you may contact us by filling up this form.

Galaxy S5 constantly freezes

Problem: Sometimes while playing a game, or filling out a form, or just reading my phone screen will not respond to any touch command. It won’t scroll, add or delete, and I will not be able to return to a previous page or screen or move on to another. I finally end up shutting down my phone, count to ten and turn on my phone again. It use to happen quite often, but now it has been several weeks since this happened. What could be the cause of this, and what could be done to correct this issue?

Troubleshooting: There are several factors to consider when troubleshooting this problem as it can be caused by a rogue app, corrupt caches, bad update or a general firmware glitch. Try to isolate the problem first by booting in safe mode. Please take note that booting the phone in safe mode isn’t supposed to fix the issue, rather, it will give you an insight either your third-party apps have something to do with the problem or not.

  1. Turn off the phone completely.
  2. Press and hold the Power key and the Volume Down key.
  3. When the phone starts to boot, release the Power key but continue holding the Vol Down key until the phone finished restarting.
  4. Safe mode will be displayed at the lower left corner; you may release the Volume Down key now.

Now that all third-party apps are temporarily disabled, observe your phone to see if the freezes still occur. If so, then we can almost say that the problem is with the firmware, although there’s still a chance that one or more of the pre-installed apps keeps crashing and resulted in system crash as well.

But assuming that the problem didn’t occur in safe mode, a third-party app is causing the problem; find it and uninstall it.

Now, if the freezes started immediately after an update of any sort, all you got to do is wipe the cache partition. This procedure is effective in fixing issues caused by either minor or major updates.

  1. Turn off the device.
  2. Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
  3. When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  4. When the Android System Recovery screen appears, release the Volume Up and Home keys.
  5. Press the Volume Down key to highlight ‘wipe cache partition.’
  6. Press the Power key to select.
  7. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  8. Press the Power key to restart the device.

Lastly, if all else fails or if you don’t know which third-party app(s) is causing the problem, backup all your data, files, music, videos, photos, etc. and do the master reset.

  1. Turn off the device.
  2. Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
  3. When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  4. When the Android System Recovery screen appears, release the Volume Up and Home keys.
  5. Press the Volume down key several times key to highlight ‘wipe data / factory reset.’
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

Problem: The screen is frozen on the wifi network settings won’t let me do anything else says its scanning but won’t go to the next step or let me do anything else on the phone one minute it was fine the next it was frozen.

Troubleshooting: While this problem is not entirely the same as the first issue, you need to follow the same troubleshooting flow:

  1. Isolate the problem by booting the phone in safe mode.
  2. If the issue started after an update, wipe the cache partition.
  3. Then, if all else fails, hard reset the phone.

Please follow the steps above.

Galaxy S5 doesn’t go idle

Problem: The phone does not go idle. If I want the screen to lock I have to press the power button if not it stays unlocked and open  Draining the battery. If I press the power button it locks lie it should.

Solution: No need to worry about it as there’s no problem with your phone. All you need to do is set the screen timeout.

  1. From the Home screen, tap the Apps icon.
  2. Find and tap on Settings.
  3. Scroll to and tap Display.
  4. Touch Screen Timeout.
  5. Select your preferred duration (e.g. 30 seconds).
  6. Now your phone should go idle once the screen timeout duration has elapsed.

“Unfortunately, Network Service Provider has stopped” error

Problem: Today my phone was updated and once it restarted, the message “Unfortunately, network service provider has stopped” appeared and now my phone is useless. I can’t make calls, send texts, use apps, etc.

Troubleshooting: The Network Service Provider service is one of the core services, so this error means it’s a firmware issue. Try wiping the cache partition first to know if that would make a difference because there’s a chance it’s just some corrupt caches that caused the service crash. If it failed, then you have to reset your phone.

Galaxy S5 freezes while browsing

Problem: My issue is that the phone when typing and texting, loading up Internet Explorer , the keyboard allows you to type one word and then freezes for about 3 seconds and lets you type one word at a time again if you wanna type more words.

Troubleshooting: Try to find out if the problem happens with other apps. If it happens only while using a certain app, then just clear the cache and data of the app. If it failed, uninstall it and just download a fresh copy from the Play Store. However, if the issue also happens with other apps, then the problem is the Samsung Keyboard. To fix it, clearing the cache and data is necessary. Please note that you will lose all your saved words when you clear the data.

  1. From any Home screen, tap Apps.
  2. Tap Settings.
  3. Scroll to ‘APPLICATIONS,’ then tap Application manager.
  4. Swipe right to the ALL screen.
  5. Tap Samsung Keyboard.
  6. Tap Clear Cache.
  7. Tap Clear Data, OK.

Getting rid of update notification

Question: I am being prompted to update my software to lollipop. I don’t want to but I keep getting the notice for the update. I want this update request to go away. Can this be done? I have done a force stop…but I still get prompted/notices to update my phone.

Answer: Nope. You can never get rid of the notification…unless your phone is rooted. It will keep bugging you until you decide to download and install the new update.
