You may want to run some apps but are constrained by minor issues like lagging / stalling, stuck on app screens, touchscreen does not respond. These symptoms will usually be experienced when you have a smartphone whose age of use is quite obsolete. From time to time applications will increasingly consume memory storage, ram capacity for caching and cookies. This will certainly be very ugly when you want to enjoy in-app entertainment but the application suddenly out on its own or can not respond to your touch.
First open the "Settings" or "Settings" app on your smartphone.
Scroll down until you find the "Memory" or "App Manager" option.
Then switch to the "Memory used by apps" or "Running" tab to see which applications are running.
Choose an app that takes up a lot of RAM on your smartphone, then select "Force Close" or "Force Close".
