Most owners of Android devices know that on a smartphone or tablet you can initially find a bunch of unnecessary junk in the form of pre-installed applications. Judging by the reviews, most of them are not only not needed by the ordinary owner, but also cause quite serious indignation that such programs are constantly updated without his knowledge and take up space in the internal storage or use RAM. How to uninstall the Android system applications will now be shown. And it is not necessary to have root or superuser rights. But first things first.
How important are system applications?
Many people think that all the built-in applications of Android-systems are “sewn” into the operating system and are mandatory components for its functioning. This is not true.
In addition, any device based on this OS has at its disposal unnecessary services that use Google registration with confirmation via Gmail. The question is: why register the same Google+ account if the device was initially verified by the standard procedure?
And if you look at services like Google maps, it’s easy to imagine how much space they occupy in the internal storage. There are no questions regarding applications using geolocation, but most uninitiated users do not need this. Removing system applications w3bsit3-dns.com (a specialized site dedicated to mobile gadgets) is recommended to be done in several available ways, even if there are no root or superuser rights, which is often a prerequisite. Consider the most common options.
Removing system applications of Android devices: general rules
Immediately we distinguish between understanding the removal or disabling of standard programs with similar actions based on firmware. With system firmware, the situation is much simpler, because in most cases, even when they are installed, intervention at the supervisor level is required by analogy with Windows systems, where there is a super administrator account. The point is the same.
Some programs installed on Android devices can circumvent these restrictions, especially with firmware, but a “clean” system can easily resist making changes. Hacking the OS to provide developer rights, so to speak, is quite simple. But uninstalling Android system applications correctly will be problematic.
Using Explorer Type Programs
An inexperienced user needs to know that logging into the Google Play service with an attempt to remove some application will not work (it simply will not be displayed there). Manually deleting program files is also a thankless task, since most users do not know where all these objects are located. In addition, many of them may be hidden or contain data in locations other than the directory of the installed program.
In the simplest version, you should use Root Explorer or its analogues (Framaroot, Titanium Backup, Root App Remover).
In the "Explorer" you need to find the item of funds and, having entered the menu of the root-explorer, agree with the submission of superuser rights. Then, in a new window, confirm the R / W connection, and then search in the app directory located in the System directory.
When the necessary APK format files are found, you need to delete only applications, but not services (think a hundred times before doing this). But that will not be enough. At the same time, you should delete all objects of the same name with the extension .odex. Only after that the system will be cleaned. Some have suggested that this cleaning method removes registry entries. Let us disagree with this, because in Android, built on the basis of Linux-systems, there is no registry at all.
System app remover
In the previous case, deleting preinstalled applications can be very wrong. So, for example, a fairly large number of cases of “demolition” of the Wi-Fi module are known, as a result of which users were left without communication. Returning the initial assembly after this is very difficult (but possible).
Another thing is the official System App Remover utility, which can be downloaded even on Google Play. Only root privileges are required. But the application filters the system components, giving the user the right to choose, highlighting categories like “You can delete”, “Better to leave”, “Delete is unsafe.” In the simplest case, the removal concerns social network widgets (Facebook, Twitter) or similar services like YouTube. It will not harm the system.
In the second version on Android, the program does not recommend uninstalling system applications, since this may concern the list of contacts, calls, messages, etc. Again, without knowing the name of the service, you should not do such things, otherwise the phone mode can be deleted, after which making calls will become unavailable.
Removing system applications without root rights
Now a few words about the lack of appropriate access rights to change the configuration. Uninstalling Lenovo system applications, as well as other manufacturers of mobile devices, can be done independently without using privileges of this level.
To do this, you need to use the SuperOneClick and Deploater applications in parallel when connecting the device to the computer. Not to mention the principles of work, we can only note that their actions make the system believe that the user has developer rights. During the installation process, drivers are first installed, and then the main application is triggered. It operates on the basis of vulnerabilities discovered in Android 4.0, so the antivirus may perceive the program as a symptom of an external unauthorized impact.
Conclusion: the scanner in real time must be disabled. But the program deletes all unnecessary selected objects with the extensions .apk and .odex automatically.
Is it worth it to do?
Removing Android system applications seems acceptable. But do not forget that some services can be disguised, and their names will not tell the user absolutely nothing. In particular, this applies to elements whose names begin with the prefix com.android or com.google. It is here that you need to be especially careful and remove such elements of services only with a full understanding of all the consequences.
