Quick Ways to Speed up Your Slowing/Flagging Galaxy S7/ S7 Edge?

With the reasons out of the way, let us check out how to fix a slower S7 phone:

Way 1. Clear the App Cache

Your app cache files could have gone corrupt or they may be clogged. This sometimes causes your phone to become slower. The first thing you will need to do is clear the app cache. Head into Settings > Storage > Other Apps > [app-name] > Storage and tap on Clear Cache.

Older Android versions gave you the option to delete all cached files at once by going to Settings > Storage > Cached Data. From there, simply tap OK when you see the option to delete all cache files.

Way 2. Remove Bloatware and unused apps

Bloatware is the apps that come preloaded on your device. Sometimes there are a number of these stock apps on your device and they cause your phone to slow down. Getting rid of bloatware and unwanted apps will help fix your slower phone. Head to Settings > Apps & notifications > [app-name] and tap on Uninstall.

Way 3. Close Out of Apps

RAM is what decides the performance of your phone, and if it is fully used, your phone will not run fast. Exit the apps that are open but are not being used. Tap the app switcher button on your phone and then close the apps you are not using.

Way 4. Free Up Phone Storage Space

All the apps, photos or videos need breathing room to run smoothly, and if it's low on storage, it can start to slow down. If your S7 is in low storage space, you will need to free up the phone storage space.

Head to Settings > Storage. From there you will be able to see how much space is being used and by what files or apps. Tap Free up space (Clean now or similar) you will be able to delete downloaded files you no longer need or uninstall infrequently used apps.

Way 5. Disable Unnecessary Background Processes

If you have a number of apps running at the same time, this could slow down your device. Disable the processes that are running but are not being used by you.

  • Go to Settings > About device and tap on Build number seven times to unlock the Developer options.
  • Go to Settings > Developer options and look for Running services or Process statistics
  • You should see live RAM status at the top, with a list of apps and their related processes and services currently running below. You can tap on active apps and choose to Stop.
