The German consumer protection portal "Mobile Zecher.D" indicated that the applications for cleaning smartphones equipped with Google's Android system do not provide few functions or provide any feature at all, despite the prevalence of such applications in the Google Play application store.
The German technology portal attributed the reason for this to the fact that most of these applications are derived from the world of desktop computers, and are not necessary for mobile devices equipped with the Google Android system.
Ads and espionage
In some cases, cleaning applications and other OS optimization tools only bring advertisements to the smartphone, and these applications may also spy on user data, usage information and mobile device specifications.
The German technology portal recommends relying on internal Android tools instead of installing useless and dangerous external applications, and the user can find two tools in the settings menu easily.
Cache
Cleaning applications reduce files in what is known as the application cache, which is a memory space dedicated to temporary files, and the application itself removes these files, and if the pace of work of an application slows down or crashes, it may be due to a bug in the cache Here, the user can manually remove files from the cache by going to the settings menu, including apps, selecting the desired apps, then memory, and clicking on clearing the cache

RAM
There are some widespread misconceptions, including that the RAM should be emptied as soon as possible and background processes in applications should be terminated quickly, while the reality is the exact opposite.
The Google Android operating system is designed to be RAM loaded as fully as possible.
And if the user launches a new application and there is not enough space in the RAM, the Android system will take care of the matter automatically, close the less important and longer-running applications in succession, and leave the important applications "that are constantly running."
The only exception that requires the user to intervene himself is when the application crashes;
Where the user must here manually end background processes in the concerned application through the settings menu, including applications, then desired applications, and press the button to force termination.
