First solution: Force close/clear background apps then restart.

When your phone keeps freezing or lagging, it doesn’t always mean that the problem is on the device itself. It could be isolated to an application like when a specific app is going rogue. To clear this out, force closing background apps can help. Aside from freeing up memory space, this also gets rid of any crashing applications in the background. Here’s how to clear/force close background apps on your Galaxy C7 Pro:

  1. Tap the Recent Apps button located at the left of the Home button on your phone. Doing so opens a list of all apps you’ve recently used but haven’t closed.
  2. Tap and drag an app to the edge of the screen to close/clear it.

Do the same to the rest of the background apps until everything is cleared.

  1. Alternatively, you can tap the X on the top-right corner of the app’s preview to close individual apps.
  2. To close or clear all background apps at once, tap on the Close All button at the bottom of the screen.

Once you’re done clearing background apps, reboot your phone (soft reset) to dump cache from the internal memory and to refresh the operating system.

Second solution: Boot into safe mode and diagnose apps.

Safe mode can help you easily determine whether or not the problem is inflicted by a third-party or downloaded application. When you boot your phone in safe mode, only the preinstalled apps are allowed to run as third-party apps are bypassed or temporarily disabled. Here’s how to enable safe mode on your Galaxy C7 Pro:

  1. With your phone turned, press and hold the Power button until the menu options show up on the screen.
  2. Tap twice on the Restart option.
  3. While your phone is restarting, press and hold the Volume Down button for a few seconds and then release when the phone turns on in safe mode.
  4. You should then see Safe Mode on the bottom-left corner of the screen.

Use your device as you normally do while running in safe mode and see if it still freezes or lags. If it doesn’t, then the problem must be triggered by a third-party (downloaded) app. In that case, try to think of which app you’ve downloaded recently or before the symptoms started to occur. You will need to delete or uninstall that application to keep your phone running perfectly smooth again.

If the phone is still lagging or freezing while in safe mode, then most likely it’s a hardware issue. You may resort to a factory reset to clear out complex system errors but if that won’t help either, then you better take your device to a service center.

Third solution: Update phone software (if new update available).

Software updates can also fix the problem if it’s inflicted by bugs and malware. Embedded into software updates are not only new features but also fix patches to get rid of any bugs that caused various troubles on certain devices. To check for new software update on your Galaxy C7 Pro, follow these steps:

  1. Tap Settings from the Main menu or Apps screen.
  2. Scroll to and tap System Updates.
  3. Tap the option to Check update manually.
  4. If an update is available, follow the onscreen instructions to download and install update on your phone.

Then restart your phone to ensure that the new system changes are properly implemented and likewise prevent the apps from acting up following the platform transition.

Fourth solution: Wipe cache partition on your phone.

Temporary data that are stored in the phone’s system cache partition can also trigger similar issues especially when they become corrupted. There is a tendency that system functions will be affected given that all system components are interrelated. As resolution, try wiping cache partition on your Galaxy C7 Pro with these steps:

  1. Turn off your phone completely.
  2. Then press and hold the Power, Home, and Volume Up buttons simultaneously for a few seconds.
  3. Release the Power button when the Samsung logo appears.
  4. Release the Home and Volume Up buttons when the Android system recovery screen appears.
  5. On the Android Recovery menu, press the Volume Down button repeatedly to scroll to and highlight Wipe Cache Partition option.
  6. Then press the Power button to confirm selection.
  7. Wait until the cache partition clearing is finished and the Reboot system now option is highlighted.
  8. Finally, press the Power button to restart your phone.

If that still failed to solve the problem, then you’ll need to consider a full system reset.

Fifth solution: Factory reset or master reset your phone.

As your last resort, you can try performing a master reset or factory data reset. This is one of the recommended last-ditch solutions to complex system errors that caused major problems on the phone. The only downside though is the fact that you’ll end up losing files because everything will be wiped out completely during the reset. Tough bugs and malicious software have also no escape as they’ll be obliterated. Just don’t forget to back up important data beforehand so you still can recover them later. And here’s how to master reset/factory data reset your Galaxy C7 Pro:

  1. Turn off your phone.
  2. Then press and hold the Volume Up, Home, and Power buttons simultaneously for a few seconds.
  3. Release all buttons when the Samsung logo appears and then the Android system recovery menu opens.
  4. From the Android system recovery menu, press the Volume Down button repeatedly until the Wipe data/Factory reset option is highlighted.
  5. Then press the Power button to confirm selection.
  6. Press the Volume Down button again to highlight Yes — delete all user data option then press the Power button to confirm. Your device will then instigate system reset and when it’s done the Reboot system now option is highlighted.
  7. Press the Power button to restart your phone.

If your phone is screen is responsive or not frozen, you can do the alternative reset through settings. Here’s how:

  1. Tap Settings from the Apps screen.
  2. Tap Backup & Reset.
  3. Select Factory Data Reset.
  4. Then tap Reset device.
  5. If prompted, read the warning message and then tap Erase everything.

Wait until the phone is finished wiping the system and restore the default settings. As soon as it’s finished, it will reboot by itself. Wait until it’s finished restarting and then proceed with the initial device setup. Lags and freezes should already be resolved at this point unless a hardware damage is present.

Other options

If your Galaxy C7 Pro continues to freeze and lag after exhausting all prior means to clear software-related issues that might have triggered these symptoms, then service is likely needed. Your phone may have obtained some sort of physical or liquid damage from a previous instance of accidental drops or liquid exposure. In that case, have your phone be thoroughly diagnosed by an authorized technician. For other options and recommendations, contact your device carrier or Samsung Support.
