Why Should You Keep A Check on Junk Files In Android?

You might be wondering how junk files can damage your Android phone?

1. Junk Files Take A Toll On Your Phone’s Performance

Immaterial of how powerful the hardware configuration of your Android smartphone is, if you let junk files pile up, they will degrade the overall performance of your device. The response time of your Android phone will take a backseat.

2. You’ll See A Gradual Dip In Your Device’s Memory

Ever wondered why your device’s memory looks stuffed despite not loading it with many images, documents, videos, etc. It’s because of these junk files that a lot of space is taken up.

3. No Surprise That You Start Witnessing Crashes

Picture this; you try to open an app; it works fine for a while and then crashes. Why did that happen?

The culprit behind these crashes could be the junk files. When the system storage gets filled with temp data and other junk arising out of web browsing sessions and frequent opening and closing of apps, the system storage runs out of space and causes issues such as crashing.

    Thanks for the suggestions on freeing up space on this Android. I’m going to try the Smart Phone Cleaner first. If I need more suggestions or if I need to go with Facebook Lite, I’ll be back. I really do need space and don’t want to delete something I know nothing about.
