Chill guys we all face this problem with our smartphone after some days. Basically we are all familiar with the term "Dump". No problem i will cover the term Dump and what it basically means, it means that Junk files and Miscellaneous files on our Android Device. We all know and Let me tell you that the number of Dump get increased basically on Android Phones the most. Android is such an operating system that gets least affected by Virus because of Linux Os as it is the only Os free from viruses. Periodically if we clear Junk files and Cache then I think the smartphones run free. To do that you can go to Storage apps and data and then you can see. The most easy process is to Hold the Volume down and Power button while your smartphone is rebooting.
