How often should we clean junk files off our phones?
Some says you never have to clear off junk files.
But I think it's necessary to clean junk from time to time. The frequency depends on how you use your phone.
If someone is a heavy user of Vine, Instagram, whatsapp or mobile browsers, he / she probably needs to clean junk once a week.
I myself had experienced lag when scrolling my phone's screen, and after I cleaned a good amount of cache, the lag will be gone.
What do you think of this problem?
