Users of Android devices running version 6.0 or higher are more likely to report this error, but users of older versions may also find it.
List of the most problematic devices:
- Sony Xperia smartphone.
- Wide flying models (from 406 to 505 m).
- DEXP, DIGMA, HONOR and other similar devices.
If you don't find your template in the list, don't worry. You can try our method to fix the problem and it will probably work because all Android devices have the same settings. If the phone is new and not yet configured, the error may frustrate the new owner. The same effect occurs when changing the firmware, after which the phone is reset to factory settings.
How to solve a problem
The good news is that if you have one of the smartphones listed above, you can set all the settings yourself in most cases.
Not only can contacts and call logs be missing, but also text messages, application settings, external storage settings, and much more.
Create permissions through the Connect app
Touch contact list - since we are now interested in:
- Open Settings from your phone menu.
- Select "Devices" and "Applications". If you don't have the first option, select "Programs".
- You will see a large list of programs, click the “Connect” button.
- If a large section appears with too much information, look for the Permissions section.
- A menu will open with various options to enable or disable the resolution.
There is no need to understand whether special permission is required. If you disable some of them, programs and errors will appear.

or
To copy this file you must have administrator rights
Fixing the error
To solve this problem, we do the following: Go to the properties of the problematic folder (or drive), for example, for me it is drive D: Next, go to the Security .
In the “groups or users” there should be “Everyone”; if you do not have such a group, then you need to add it.
Next, click “Change” .
A window will open in which you need to check the access level (full, read, write, etc.), apply.
After these steps, you will have full access to work with files and folders on your computer. Good luck.
Using this method, you can also restrict or allow access to other users of your computer to their personal drives, folders or files. In particular, you can completely deny other users access to certain folders or files or only allow them to be viewed, which can prevent accidental or special deletion of folders or files that are important to you.

Why do I need permission
Permissions can be transferred to a specific application or part of the smartphone. These are some of the application rules you set.
No doubt you have received a lot of permissions when installing new software. It doesn't matter if it's a game or a business program - you're approved no matter what permissions you have. The main function of these applications is virus protection and device optimization.
Programs usually require access to the camera to improve image quality. This is because the system responds faster and allows you to take high-quality photos with just one click.
The required permissions are still worth checking. If an item seems questionable or unusual, write to a professional or look up the meaning online.
You do not have permission to open this file. Contact the owner or administrator
Question from a user
Hello!
I need to edit the "hosts" file, but I can't do it because... When opening a file, I see an error: “You do not have permission to open this file. Contact the owner or administrator." What can be done?
I completely checked the system with an antivirus (Doctor Web), no viruses were found...
Hello!
Well, in the vast majority of cases, this happens due to some settings in Windows, viruses and security programs that block access to many system files (for example, antivirus programs, no matter how strange it may sound).
By the way, as for Dr.Web, its healing utility CureIT often blocks access to the hosts file.
Below, I’ll look at how to fix everything...

The required permission in Contacts is missing - what to do
Manufacturers of modern smartphones are trying to bring the security of their devices to the highest level, which sometimes leads to strange and frightening glitches. It is worth noting that most often there is nothing fantastic about them, but an inexperienced user immediately falls into a stupor when he sees an error like “The necessary permission in Contacts is missing.” How to deal with this? We'll tell you in this article.
The Contacts application in Android phones is the most important
List of possible victims
An error appears on the screen when you try to access your phone's contact list or add a new one to the database. Most often, owners of devices with Android versions above 6.0 complain about the bug; it can also appear on older smartphones.
The most common hostages of the problem are:
- Sony Xperia devices;
- Huge group from the Fly line (often 406 to 505);
- Smartphones DEXP, DIGMA, HONOR and with a similar engine.
If your model is not on the list, don't panic. Our solution is suitable for most devices running Android OS, the settings are the same everywhere.
Causes of the problem
The appearance of the “Required permission is missing” error often haunts owners of new phones that have not yet been configured, greatly clouding the purchase experience. In addition, a change in firmware can also be a catalyst, because in the event of a software failure, the settings are rolled back to the factory settings, which brings problems not only in blocking “Contacts”.
Why do Android apps ask for permissions?
The inviolability of confidential data and the safety of the privacy of Android device owners directly depend on the installed applications, or, more precisely, on the permissions that are granted to them.
Many users who assign certain permissions to new applications on Android may become confused, not having sufficient knowledge of certain concepts and processes. Why does an application that does not perform the corresponding tasks request access to the camera, phone book, and even quick messages? The answer is clearly ambiguous.
We suggest mentioning the scandal that arose last year related to Facebook Messenger permissions. If you pay attention to all the permissions that this program requests, you can come to the conclusion that it can manage your personal life without your knowledge.
As it turned out later, the root of the problem lay in the intricacies of the architecture of Android programs, since applications with different purposes request extremely similar permissions. To operate, for example, a flashlight, you need to obtain permission to take photos and videos without appropriate confirmation from the user. The bottom line is that the LED diode, which is used as a flashlight, is an integral part of the smartphone camera circuit. If the program has access to the flashlight, it means that photo and video recording is also open to it, which is why the request for these permissions appears.
However, self-interested application creators also include in the list of permissions those that allow you to count on profit thanks to donations (internal purchases). Such cases can be quite risky if you do not have a password for making purchases in the Market. Obtain permissions for functions such as program history, phone book, location identification, typical for clients of social networks, browsers, navigators. But under no circumstances should they be present in games, or, as stated earlier, in “flashlights”.

Be especially careful with free applications, as they can transfer personal data to third parties or are “stuffed” with advertising from top to bottom. It is recommended to carefully research the required permissions when installing programs to avoid becoming a victim of deception. Also remember the fact that spending a dollar on an app is a wiser move than giving dozens of permissions to other free alternatives.
Don't install applications that are not particularly important to you. Taking the time to carefully review all required permits will help ensure that risks are minimized as much as possible.
Change location permissions
To manage access to the application location on our Huawei mobile with EMUI 10, we need to enter the Settings menu. Then we will have to enter the option Access to location and then on location.
Three options available
By going to this menu we will see all the applications installed on our computer that have location-related permissions . In this menu we can distinguish three cases:
- Always Allowed : This is a list of applications that have constant access to a location regardless of their status or execution.
- Allowed only while in use - This is a way for apps to access your location only when in use. This way we protect our privacy in circumstances where the app doesn't need to know the location and we save battery life.
- No Permission : The list lists apps that do not have permission to access the location.
Select each application
Now we can choose which apps can have which type of location-related permission . For example, it's possible that we use WhatsApp or Google Maps real-time location and we're interested in the app having constant access to the location, but that's something that games and other types of apps that we use less often can do without frequency .
