Applications in operating system Android is a very simple process, just a few taps on the screen and you're done. However, there are applications that refuse to uninstall. This situation occurs due to the fact that some applications are installed as a device administrator, while others are already installed (pre-installed) by the device manufacturer and the user does not have permission to remove them.
For complete removal preinstalled apps will be required root rights... If you do not want to root the device, then you can try disabling preinstalled programs so that they don't run with Android and take up RAM space. So, how to remove non-removable applications.
Device administrator applications require more rights for their full functionality. This should not be confused with applications that require, just that the administrator's programs need more authority within the existing user rights. For example, to set up protection or remote blocking of a smartphone, track it using GPS, etc.
If the application you installed is not deleted, then go to the settings of the android device, go to the section " Safety"And further into" Device Administrators", In which you can uncheck the program to be removed that it is an administrator.
After that, the application will be uninstalled without hindrance.
Remove or disable preinstalled apps
There are manufacturers who abuse the installation of their programs, which cannot be removed. You can delete them, as mentioned above, only by getting root-rights on the device. But what if there is no desire to do this or the smartphone / tablet is under warranty and its root serves as the basis for canceling the warranty? In this case, you can try stopping the preinstalled applications. To do this, do the following:
Disabled pre-installed apps should disappear from the menu and will no longer launch with Android, and also take up RAM, what in budget smartphones will be a big plus, where it is always in short supply.
Incredibly simple. To do this, you need to find the desired program or a game, read the description and reviews of other users, after which you can safely click on the "Install" button. Removing apps is as easy as a few taps. However, from time to time the system refuses to remove certain programs, not to mention the applications pre-installed by the manufacturer. How do you get rid of this problem? Let's find out.
In general, there are two reasons for refusing to uninstall an application. In the case of the former, the annoying program can act as a device administrator. The second option is much more common, and each of us has probably encountered it. These are applications that are part of the smartphone system. In other words, programs preinstalled by the company's engineers, for which there is simply no uninstall key.
Possible solutions to both of the above problems were shared by our foreign colleagues from phonearena... Let's take a look at each of them separately.
Administrator application
Do not rush to close this article: there is nothing wrong with this phrase. The point is that some applications require broader authority. For example, set a password on a smartphone, block it, track geolocation and much, much more.
V in this case to remove them, it is enough to uncheck the special section of the menu. In my good old Htc one S, which returned to use after the iPhone, for this it is worth going to settings - security - device administrators. One problem has been solved, but what about the other?
System application
Not all smartphone manufacturers love their users. The proof of this statement is a huge number of absolutely useless pre-installed applications, which there is no desire to use. In a Taiwanese smartphone, again, these include the icon for EA Games, Friend Stream, Rescue, Teeter and other dubious programs.
Agree, it's not so much their presence that annoys here as the impossibility of getting rid of them, right? However, it turns out that there was a way out of this situation as well.
To do this, you need to go to the application manager, select the hated program and find the "Disable" key. Following this, you can also clear the application cache.
The result will not be long in coming: the marked applications will disappear from the menu and will no longer remind of themselves. However, it is not always possible to get rid of them completely: most likely, some programs will occupy several megabytes in the bins of the memory card, but do not forget about the main advantage. The disabled application will not start when the device is turned on, thereby saving RAM and, accordingly, the device's battery. Not bad, isn't it?
Be that as it may, do not forget that many system applications affect the operation of the smartphone as a whole, and therefore it is worth experimenting with disabling them very carefully.
