Phone does not see USB flash drive

Why phone does not see the micro SD card

Thanks to the SD card, users have a phone with more memory and increased performance.

  • If there is an error and the microSD flash drive cannot be read, you need to try to restart the device. You can select “Restart” command in the menu. An alternative variant: manually switch off and then switch on phone;
  • With the phone turned off, user should open the cover, remove the battery, and then remove the flash drive. You need to check the phone for fine dust and debris, clean the gadget and the flash drive with a dry napkin. After the battery and the MicroSD card return to their place;
  • Turn phone on and check if flash drive is working.

When you connect the hardware via OTG-cable, the program will detect it and mount it by itself. You should be able to find the contents of the drive in /sdcard/usbStorage/sda1. Remove the stick safely by pressing the “Unmount” button with StickMount.

To the Android phone you can connect a flash drive and even an external hard drive through an OTG adapter, but it is not always possible to do it the first time. The causes can be different, from the wrong file system to partial damage to the connector on the smartphone.

Today’s popular file managers on Android OS are: “File Manager”, “ES Explorer”, “Total Commander”, “X-plore File Manager”, “File Commander”, “ASTRO” and others. There are really many of them. I’ve been using X-plore for a very long time. I have liked Android since the days when the Symbian OS was popular on smartphones. X-plore. convenient, functional and free file manager. What else do you need?

Next, simply plug the flash drive into the phone and access the file manager. There it will be displayed with all its content. Of course another question is if the smartphone can work with all the files? This is not a computer after all. But the basic ones will be able to work. There are even special programs to work with Excel spreadsheets, but it’s so inconvenient that I don’t even know who these programs are written for.

How to test the compatibility of Android and OTG

Unfortunately, not all smartphones can boast support OTG-protocol. But how do you know in advance if the device will be able to recognize an additional gadget? The easiest thing to do is to make a visual determination. If your phone has a standard microUSB, most likely it will connect to the adapter without any problems.

But for a better test recommend using a special program, namely USB OTG Checker. This is a very useful application with a minimum of functions, perfectly performing the main option. recognizing OTG support or lack thereof on your Android smartphone.

USB OTG Cheker Application

You can easily download the tool from Google Play. After installation start it and after a few seconds you will see on the main screen either a green square or red. Here everything is clear: green means that synchronization is successful, red means that you cannot connect to the adapter.

If the result is negative, you have two possibilities to solve the problem. Perhaps the flash drive is simply not recognized by the built-in Explorer. There are special utilities for this purpose, which will be discussed below. Or OTG protocol is blocked in the device at all. Then, unfortunately, there’s nothing you can do but buy a new Android phone.

Flash drive is broken

Any technical devices break down over time (or because of mechanical damage). From there, if you have applied each of the top methods and it has failed to help you, there is a good chance that the SD drive is simply broken.

To check it, you need to install the flash card in another mobile device. If the new phone also does not notice it, it is likely that your SD card is broken. It can cost a pretty penny to fix it in the service center. Therefore, in this situation, it will be easier to buy a new SD-drive.

Software failure

The software failure can be suspected, if the stick is not seen only by one of the applications on your phone. but with the rest of the full order. In such situation it is necessary to poke through the settings of this “problem” application. You will probably find that the internal drive is selected as the storage location. Set the place of data storage removable memory.

The Camera and Gallery apps are the most common worries for users. Complaints that the phone does not see photos from a flash drive. plenty.

You can only solve your adapter problem if you understand what caused the adapter to have this problem. It is necessary to find the root of all problems. Below is a review of all the possible causes, as well as the most effective methods to solve them.

Incorrect card format

In order to fix this situation, the user needs to perform the formatting procedure of the flash drive. It is often mistakenly perceived by users: they think that under formatting means the complete deletion of files on it. Yes, of course, in this process, all information from the card will disappear, but this is not important, the important thing is that formatting is a format change. Hence the name of the process. It is also possible that the card is programmed to a standard which is not supported by the device.

Important! If previously the stick was able to be detected by the device, and now it is not, then the problem lies not in the formatting. You can only consider the wrong format if the flash drive is brand new or has been formatted before.

As a rule, most smartphones support FAT32 type. This is the most common and correct format. It is different from other modern formats like NTFS and exFat. In order for the user to correctly return to the desired format, he only needs to perform the following procedure c Android:

  • First you need to connect the flash drive to your computer. You can do this in any convenient way, for example, using OTG;
  • Next, you need to open the section “My PC” on your computer;
  • Now it is worth finding the icon of your own memory card. Click on this icon with the right mouse button;

Please note! Formation deletes all data.

The memory card contacts are faulty

A SD card is a very small flash drive, a file removable media, which is quite small in general. At its end the user can find special contacts in gold or yellow. With it, the user can read through any other device.

Due to the fact that the user can remove and put the card back in rather carelessly, the media (the golden notches) can wear out. This can happen after 10 years or after a couple of months of active use. The drive needs to be handled carefully, its condition depends on it.

To check it, remove the memory card from the slot, and then pay attention to what its contacts are, whether there are kinks or various damages. If there are such shortcomings, then you should not be surprised that the phone does not see the card. This is a common enough reason why the user may need to get an additional card at all, buy it.

Experts say that it is worth replacing the drive every 3 to 4 years. This is just to help avoid problems with the contacts.

The damage of the connector

Previously, batteries were only with a removable battery, so the card was inserted under it. However at the moment almost all phones have special slots in which the data is inserted. They can look quite unreliable, so it can be quickly damaged. This can lead to the fact that it will be impossible to read information from the flash drive.

To solve the problem on their own is difficult, and the only thing the user can do is to check and check the slot for damage and defects with a flashlight. If there is damage you need to contact a service center to have the connector repaired. This is the only way to solve the problem correctly.

Software and system failure

If you look at it from a software point of view, a memory stick is such an item, which in turn can be called a smart device for its operating system. Android is often prone to viruses. They can easily take and bring all sorts of problems to the gadget, such as a crash. At the end it appears that the flash drive is impossible to work with.

If the memory card is counted on another device, and not the right one, and the memory card is completely fixed, you need to download Kaspersky. antivirus, which can be found on the official website in the application Google Play.

With Kaspersky you need to check for viruses. This can be done this way, which can be found at https://youtu.be/PnvFAZDlytU

If the antivirus does not help, it is worth doing a reset:

Important! Always remember that the resetting of the password and any data in general can have a negative impact not only on the device, but also on the storage itself. It is a good idea to back up your data before you perform the operation.

Why the phone does not see the flash drive and what to do. the instruction

The built-in memory of the smartphone is not enough for all users. Many people buy microSD flash drives in order to save all their photos, videos, and apps. The corresponding slot is on most Android-smartphones.

But, unfortunately, buying a new memory card can turn into an unpleasant situation. For example, when the phone refuses to accept it and simply does not determine. The problem can also arise over time, even if the flash drive worked steadily for several months. Why does this happen and how can you fix it??

phone, does, flash, drive

First, you need to understand that the memory card is a medium with a sensitive chip, which stops working when there is contamination. In addition, because of the small size of the stick can easily break, which, of course, will lead to the inability of the phone to detect. These are not the only reasons that can lead to such a problem. Today we will look into all the causes of memory card failure, and offer several ways to get rid of the error.

Phone doesn’t see the memory card. what to do first

If you are faced with the problem that your smartphone stopped seeing the flash drive, you need to find out if it works. In most cases the error is caused by a defective external drive. To find out if it is functioning, you can in one of several ways:

In the first case you need to remove the drive from your phone and put it on another smartphone. If a third-party gadget sees the flash drive, then the error is not caused by it, but by your Android smartphone.

In the second case, you need a special adapter, which usually comes with the memory card. USB flash drive is removed from the phone and installed in a plastic adapter, then it is connected to PC via SD slot.

If your computer does not have an SD card, a USB adapter from your local electronics store may be helpful. Check if the PC can see the memory card.

If the answer to this question is affirmative, don’t worry about the flash drive condition. Otherwise the problem appears entirely on the conscience of the carrier.

Why phone does not see the SD card

The solution to the problem depends on what caused it. Below we will consider in detail all the causes and suggest the most effective ways to eliminate the error.

Incorrect card format

Formatting the flash drive is mistakenly perceived by users as deleting files. Indeed, in this process, all information disappears from the drive, but another important point is. Formatting is changing the format. It is possible that the standard programmed into the memory card is not supported by your phone.

If the stick used to be determined by the phone, but then stopped, then the problem obviously lies not in the formatting. Consider such a variant is worth considering only with new drives or after an accidental formatting.

Most smartphones support FAT32. It is the most common, unlike the more modern NTFS and exFAT. In order to return to the most suitable format:

  • Connect the flash drive to your computer in any convenient way.
  • Open “My Computer.
  • Find the icon of your memory card and right-click.
  • Left-click on “Format.
  • Select FAT32 as the file system and run the process.

As a rule, formatting doesn’t take long. The drive quickly adapts to the new format and is ready to use again.

Once the process is complete, you need to insert the memory card into your phone again. If the device sees it, then the problem is solved. But remember, formatting will erase all files.

The memory card contacts are faulty

MicroSD flash drive. removable media is small in size. At its end are special gold-colored contacts which, in contact with the smartphone interface, allow you to read information through the smart device.

Because users often remove and reinsert cards, the media wears out. It might take ten years of use or just a few months to format. Much depends on how carefully the drive is handled by the owner.

Remove the memory card and pay attention to its contacts. Check them for visible damage or scuffs. The presence of such flaws is a fairly common cause of the error. You are unlikely to be able to solve the problem yourself. You can only wipe the contacts and if this does not help, you have to buy a new flash drive.

Do not use the same memory card for many years. Replace the drive at least once every 3-4 years. This will avoid contact problems.

Damaged connector

Until recently, smartphones had removable batteries and the flash drive was installed directly under the battery. These days, almost all devices get a monolithic case, where the memory card must be inserted through a special slot. As a rule, it does not inspire confidence because of its design. It can easily be damaged, which later leads to the inability to read the flash drive or SIM card.

The only thing that the owner can do in this situation. to check the slot and the connector itself for defects. You should illuminate the interface with a flashlight. If there is still damage, do not try to repair it yourself. Contact a service center to solve the problem or buy a new smartphone. Unfortunately, this is often the only method of fixing the error.

Software-system failure

The memory card is an element that interacts directly with the smartphone, which in turn is a smart device on its operating system. Android is notoriously susceptible to viruses. They can make serious changes in the work of the gadget up to the inability to identify the flash drive.
