When the smartphone hangs up, something can be done initially.
Nowadays, do not be thinking about the phone. Many people take care of this phone more than themselves, but change the look of your favorite smartphone as long as it goes. Slow phones, junk file leads, storage also decreases But in some ways the phone can be re-branded as new.
Keep phone software updated all the time. That is to say the whole operating system is updated. Whatever the iOS or Android, it will have to keep updated from its app store. The phone will become slow without regular updates.
If you do not uninstall, many apps get accumulated on the phone. There are many of them installed with interest, but they are not used. Find out which apps are no longer needed or you no longer use. So just drop the phone's storage heavily.
In both OS and Android operating systems, some apps are available in the background. At the end of the work, this facility was kept back to the previous place. Feel free to stop these tasks at the end of the job. Ram will be free.
The Android home screen has many options. Widget can be added. This makes it possible to easily move to the desired app. But the home screen became irregular in their use. So who does not need them, do not keep those icons on the home screen.
If the phone is slow to go from another app to another app, then reduce the animation that is working on the operating system. Good use of live wallpapers, other special pictures, etc.
Uninstalling the app will only empty the storage. Regularly clean temporal files. Clear the browser. The history should be cleaned regularly.
When the phone is not giving any speed, you can take a bigger step. Give a factory reset. It will clear everything. You must first back up all the information on the phone. Neither will you get in trouble. The factory will be completely new if the factory reset.
