Why can t I install the software that was able to be installed in the mobile phone software now?

The mobile phone cannot install software, and Samsung mobile phones generally carry out the following steps to troubleshoot and deal with it:

1.Check that the "Unknown**" setting is turned on.

5.If it doesn't work, back up the data in your phone (contacts, messages, **, etc.) and try to restore factory settings.

If the problem still exists, please bring the purchase invoice, repair card and machine to the service center, and the professional after-sales engineer will help test it.

1.Settings - Lock Screen & Security - Install Location Apps - Select Allow Apps to Install - Allow This ** - Turn on.

2.Settings - Lock Screen & Security - Unknown - On.

3.Settings - Security - Unknown - On.

4.Settings - Application - Unknown - On.

People always grow up with various things, of course, some are happy and some are painful. But now that it's happening, what can you do? If it is happy, enjoy it, and if it is painful, face it.

If one day you grow up, you will be relieved to look back at this matter.

The mobile phone always installs software automatically, and the general reason is that the mobile phone has a rogue plug-in installed. The solution is as follows:

1,In fact, if the mobile phone automatically installs the software,There must be a software to execute,In this case,You can go through the phone's settings - traffic usage,See that the software uses too much traffic,You will know the problem。

2,After opening the traffic usage,There will be an Internet situation or traffic ranking,Take a look at the software is not commonly used,But it consumes a lot of traffic abnormal software,You can uninstall it。

Because there are some rogue software installed on the base key on the phone. Just find these rogue software and delete them.

Open your phone's settings and find Security Management. Turn off the unknown ** pickpocket option, and after turning it off, the phone can only** and install the apps in the app store that comes with the phone.

Factory reset and phone formatting. Before formatting, you can use the backup function in the toolbox of the app treasure to back up the data in your phone before you operate, which can reduce the loss.

Harmfulness. For users in need, the mandatory pre-installation software of licensed mobile phones can improve the experience of using mobile phones, while for parallel mobile phones with a huge user group in China, the pre-installed software should be resolutely resisted and vigilant, because the pre-installed software of parallel mobile phones will directly affect the safety of consumers' mobile phones (including privacy, phone bills) and other vital interests. The "three nos" characteristics of the spring stove of the mandatory pre-installation software industry chain of parallel mobile phones determine that it is difficult for consumers to seek justice after being recruited.

Try it with the Anzhi market update, if it doesn't work, just flash it!The mobile phone has been used for a long time, and it is much better to brush the machine without it!

You'll need to clean up the previous programs before you can install them.

Can't you be bad with a memory card?91 can put software in memory!Just ask if you need to!

Restart the unloader and try if it doesn't work, format the machine * Make a backup of contacts, text messages, etc. After the machine, reinstall the software in the card.

Since this is the case, your mobile phone is poisoned, Nokia's machine, as long as there is a certificate and the software under the software is right, you can use it, it is recommended to take a look at it after antivirus.

One: The uninstaller is not clean, or it is caused by using some cracked software such as lucky breaking.

du desolver, etc. I don't want to be able to install software, dao

1.Out of memory can no longer be installed.

2.The installation package is corrupted.

In fact, there are many reasons why Android phones can't install software, excluding avoidable reasons (Google authorization), and other hardware facilities support, there may also be software that can't be installed. Some can be solved, but some are mandatory reasons, then there is no way. Here are a few reasons why the software can't be installed.

1.Most commonly, unknown software fails to install.

This actually has this permission when you are on the Symbian phone, and this can be set in the security settings of the mobile phone. This is also an option added by the operator to ensure that users do not install unofficial applications in a disorderly manner and cause the system to be disordered.

Solution: Set the installation permissions.

2.System version reason.

Hardware facilities. What kind of horse to ride, what kind of saddle to cover, and a broken pot with a broken pot lid, this is an unavoidable problem, so you don't have to worry about it. Unless you replace what you have now, that's the only solution, otherwise you don't have to worry about it so much.

System reasons,Now many software does not support the following systems,This can still be solved by flashing and upgrading。

3.The installation software indicates that the memory is insufficient. I believe everyone understands this reason, if the memory of the mobile phone is really not powerful, and you want to install a little more programs, then change your mobile phone.

There are many reasons why you can't install the app, such as running memory is not enough, you can clean up the junk cache, restart the phone to release the running memory. There is also a file format (Android: apk format) that is not right, re-select.

Set up. Safe. Unknown Sources is checked.

This problem may be set up on the phone, and the foreign software cannot be installed, but you can set it up to install it when you enter the settings. That's it, if it doesn't work, it's just that the phone memory is full, and you can't install anything. Now you're going to clean up your memory. FYI!!

The software must be installed in the app store, and other permissions are also set. Another is that you don't have enough memory. The main reason should be in the software store.

Impossible! Is it that your phone does not have enough memory! Check your phone's internal memory, if you have enough memory, but still can't install the software, it is recommended that you restore the factory settings or re-flash the phone to empty the phone and reinstall the system!

If you can't install any software on your phone, I suggest you clean up your phone's memory and delete all unnecessary software. It may be that your phone is running out of memory. You clean up the memory first, and if you can't do it, just flash a few more of your unnecessary software.

It's to start restoring the factory settings.,And then I got the root permission.,Why can't you get in but it goes out?,What the hell is going on.。

The first thing to do is to check your phone's security settings and turn on the Allow Unknown Installation option, if you still can't install it, you need to clean up your phone. It may be caused by insufficient memory on the phone, and you need to clean up the cache and uninstall the unwanted software. Or the system cannot be installed due to the system incompatibility crash caused by the flashing of the mobile phone, and the adapted version needs to be reinstalled.

This problem may be set on the phone to prohibit the installation of foreign programs, you can go into the settings and cancel it. How to set it up is not possible yet. Maybe the memory is gone, you can clean up the phone first, maybe it's okay. FYI!!

Two explanations,Either the software is not compatible with the CPU,Or the software installed by the landlord has not been completely uninstalled,For example, you install the version of the beautiful sound every day,You install a beautiful version every day,Of course, the mobile phone will show that the application is not installed,It's best to delete the program and folder corresponding to your software,Otherwise, it can't be installed。

The mobile phone can't install other software, most of the reasons are due to their own phone memory is not enough, you can try to clean up the garbage, uninstall the software that is not commonly used, and then it may be because of the internal control of the mobile phone.

Is your phone set to prohibit the installation of unknown apps by default?

The general performance of an app that fails to install software is mainly due to the following factors:

1. The file format (Android: apk format) is incorrect, re-select.

2. Set --- Security --- Unknown Sources checkbox.

3. RAM (running memory) is not enough, clean up the junk cache, restart the phone, etc. to release the running memory.

There should be some options that you must select when installing the software. For example, the installation protocol of the software. You need to check "Agree" to install and use their software. In general, double-check pages that can't proceed to the next step, and there should be some hints.

First look at the lack of memory, and then look at the security settings, whether it is forbidden to install foreign software.
