In modern versions of Android >
The application has nothing to do with the usual key fobs. Not related to viruses either, since this is a system application: in fact, this application provides access to private keys and the corresponding certificate chains in the credential store. In short, this application is best left untouched, even if you want to freeze or delete it. By the way, the Keychain application is not deleted, as it is a system one, and besides, it is necessary for the system to work. In any case, we do not recommend touching it.
To find the app, go to settings.
Click on the three dots in the upper right corner, select "Show system processes".
The application page opens.
There is, of course, no "Delete" button here.
Friends! If our site helped you, liked it or, conversely, something did not suit you, we will be glad if you leave your comment.
Which built-in (system) Android apps can be uninstalled. There are built-in applications that we do not use, and these applications and services only take up space and eat up RAM, they can be deleted.
In order to remove some of them, we will need Root and you need to install the program Root Browser or Root Explorer. Next, you should go along the path ' / system/app/ ‘ , here are the very built-in applications that cannot be deleted. Sometimes this folder needs to be remounted read/write as it may be read-only. To do this, for example, in RootExplorer, press the button labeled " Mount R/W", if it says " Mount R/O”then you don’t need to press it, the folder is already available for recording.
We mark what we need to delete and, just in case, transfer these files to a previously prepared folder on the SD card. We transfer, but do not delete in order to be able to return everything back, otherwise you never know what. We reboot the device and they are gone. And yet, in this folder there are also system applications necessary for the functioning of Andro> the firmware is decoded, if deodexed, then these files will not be.
SystemApp Remover is a program used to remove system and user-installed applications. Uninstalling unnecessary programs has never been easier. In addition, the program allows you to create a backup of all applications. It requires root privileges to work.
1. Q: Where are the stock programs and how to remove them?
A: Stock (standard or factory) programs are located in / system/app.
You can open this directory using Root Explorer, Root Browser and the like, as well as Titanium Backup if you have ROOT rights and mount in r / w. The order and names may differ (in Titanium Backup, program names are displayed instead of .apk files). Remember that it is not necessary to immediately delete the application, you can rename it or freeze it using the Titanium Backup program. In this case, the phone will not recognize the renamed file as an application, and you will be able to restore/unfreeze it if necessary.
2. Q: What programs can be uninstalled?
A: Each user must decide for himself which system applications he does not need, then you need to see if there can be consequences from deleting applications you do not need, if there are none (consequences), then you can safely delete these applications. And if there are consequences, for example, some programs have dependencies, then you need to think about whether you delete them or not, for example, you don’t need Google maps and you will never use system and third-party programs that use Google map data, so you can safely delete these maps .
3. Q: Where else are the files from deleted applications and do I need to delete them?
A: Parts of the programs may remain in data/data, data/dalvik-cache, (system/lib- it is advisable not to touch, because. there are dependencies). The file names do not always match the application name. Be careful. To find out the "internal" name of the program, you need to go to the folder where it is located with the Root Explorer program, then short tap on the apk file - press view and see the manifest. After removal, it is desirable to do Hard reset. If you do not plan to do a Hard reset after deleting system programs, then you need to delete the "tails" from the indicated sections of the system, but I would not recommend doing this method of deletion, it is difficult and you need to delve into the name of the programs. In the above sections, programs are usually called differently than in system / app, it’s better to make it easier, remove everything unnecessary from system/app and then do a hard reset. And that's it, after Hard reset if the program is not in system/app, she clearly will not place her data in the section data. But unfortunately such a simple cleaning will not affect system/lib. In this section, the "tails" will remain. However, many, even with the complex removal method indicated in the mini-fake, do not climb into system/lib. Since this is a really dangerous folder, it is written correctly there, it is advisable not to touch it, lib with an explicit name which can be deleted there is almost none. Explicit name and association with remote programs from system/app, have only two, these are keyboard libraries.
I will explain the "danger" of the folder system/lib, after removing some lib.so if you reboot your phone or do Hard reset , the system (android) won't boot. On the phone screen, you will see a cyclic reboot (permanent reboot). You can exit this reboot either if you reflash the phone again, or through recovery mode using update.zip. This archive should contain a remote library and scripts, with commands where to place this library. That's the whole danger of the folder system/lib
4. Q: Is it possible to remove the standard Google applications, will this affect the operation of the device?
A: Applications (Maps, Gmail, Gtalk, etc.) are allowed. The service is undesirable, because if deleted, all Google services and applications will stop working, and permanent errors may appear on the device.
5. Q: Is it possible to remove the standard Google apps (Navigation, Locations, Street View) separately from the Maps app?
A: Street View (Street.apk) is possible, but others are not, since they are part of the Maps (Maps.apk) application.
6. Q: Is it necessary to delete the .odex program files along with the .apk files?
A: Yes. These files are part of the application of the same name.
7. Q: Where can I get a standard .apk file from any firmware?
A: Unpack the native firmware, and pull out the necessary file.
8. Q: Removed the standard keyboard, after which SWYPE does not work. What to do?
A: Make SWYPE system. Video instructions for installing Russian Swype:
9. Q: I installed a third-party dialer and when I miss a call, 2 notifications appear in the notification panel at once: from the standard and third-party.
A: Solution: make a third-party dialer a system dialer (I did it through Titanium Backup, but I suspect that it's easy enough to transfer apk to the system folder).
10. Q: Can't uninstall some google apps; removed from folder system/app but they still work.
A: Perhaps these applications are in the folder data/app and you need to remove them from there as well.
11. Q: How to restore system applications?
A: If you decide to restore a system program that you previously deleted (without backing up), first find the necessary .apk(if necessary.odex) files (preferably from the firmware version that is installed on the device). Download the firmware, unzip it and extract the necessary files from the file system.rfs(in some firmware it may be called factoryfs.img and have a different extension). Through Root Explorer (or another file manager with root access), drop these files into a folder system/app and set permissions rw-r—r—;
How to change permissions:
1. Long tap on the apk of the application;
2. Click Permissions
Reboot device. Once downloaded, this application should appear. Note: To install some applications (for example, Google Play Market), you need to upload apk and change permissions not only in system/app, but also in data/app.
12. Q: Can I remove the stock launcher?
A: It is possible, but only if you have a stable third-party launcher, which is desirable to make a system application. But keep in mind that not all standard widgets can work on a third-party launcher.
13. Q:After uninstalling applications, gray labels of deleted applications remain in the menu. How to remove them?
A: You should clear the launcher data through Settings ( Settings — Applications — launcher — Clear Data) or via Titanium Backup. It should be noted that as a result of this, all user desktop settings (widgets, etc.) will fly off.
14. Q: How can I remove the default lockscreen?
A: Removing it is very problematic (for this you need to edit several system apk), and you can disable it through Settings — Lock Screen. Or via ShutdownApp (service tag *#7594#
; note that in this case the reboot menu will also disappear).
15. Q: How can I see running background processes?
A: Enable information layer with CPU usage data ( Settings — Developer Options — Display CPU usage).
Before removing system applications, make backups (or freeze) programs in Titanium Backup. In case of unsuccessful deletion, restoring a backup is much easier than searching the forum for the files you need.

Hi all! Today we will talk about the KeyChain Android application, aka Keychain. You will find out what the Key Chain program is and what it is for.
Recently, many users of Android devices have complained about the random installation of the KeyChain application (some may have the name Keychain). The program is loaded by a virus that is disguised as a hidden system process.
Key Chain (Keychain)- this is a password storage for various accounts (social networks, google accounts, games, etc.). Thanks to this program, you will be able to manage your passwords, change them and set up access levels.
The main features of the application:
The program is certainly useful, but the free version is limited to three passwords and pin codes. For using a large number, you need to buy a paid version, which also disables ads. Here is a visual video instruction for working with the Keychain application.
If we talk about its need, then it will be useful only if you are really worried about the safety of your personal data and are not averse to applying double protection. Otherwise, there is no benefit from it, especially since there are a large number more popular analogues.
The fact that it installed itself on the phone itself speaks of a virus infection. The program itself is not a virus, and its distribution in this way is just an advertising campaign. Also, a minus can be called constant work in the background, as a result of which it goes to the processor.

Good day to all DIYers. One early morning I had an idea to decorate my keys with a keychain, but I didn’t want to buy it, I decided to make it myself. The keychain itself was intended to be made in the form of an android, since I have been communicating with it for a long time, and in connection with this, the idea was made to create a talisman keychain.
In order to create such an original keychain with our own hands, we need tools such as:
* Jigsaw, with a small supply of files to it, in case of breakage, to replace it with a new one.
* Sandpaper, several types are needed, or rather, grit from coarse to fine zero.
*Small vise.
* Board or, in my case, oak parquet, a fairly durable material.
*Pencil.
*Green and red lacquer.
