Why can t I use a memory card installed on my phone?

If you want to transfer files from your phone to an external SD card, please do the following:

1.If you want to move multiple files from your phone to your SD card: My Files - Device Storage - Find the folder you want to move - More - Select the files you want to move - Move to, return to external SD - Click Move here.

Vice versa. 2.Some mobile phones support moving software to SD card, operation: Settings - Applications - Application Manager - Open a certain software - Storage - Select the used storage space - Change - Select SD card (or Settings - More - Application Manager - Select a program - Move to SD card).

Hello: According to your description, Samsung S7572 phone does not support installing software into SD card, we recommend you:

1.Move the software data package stored in the phone and the multi** files of the phone to the external SD card.

Welcome to Samsung's Digital Services platform.

There is a possibility that the memory card is used only after using up the phone's memory.

1. The unknown ** of the phone is not opened.

This is 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. Workaround: Turn your phone's location** on.

2. The installation software prompts insufficient memory. Solution: Free up the memory space of the phone by removing some useless third-party programs, 3. The installation position is incorrect. For example, some programs are installed in the phone's internal memory by default when they leave the factory, which are built-in system applications, and they can only be installed in the system space. For R827T, R833T and other models that support external SD cards, some users will select the "SD card" space as the preferred installation location, and if the SD card is unplugged in the future, the installation will fail.

Workaround: Leave it up to the system to select the preferred installation location.

4. The system version is too low. At present, many software does not support the following systems, and the installation failure caused by this situation can be solved by upgrading the Android version (for example, the model of U701 has been upgraded from the system to the system).

5. The installation file is parsed incorrectly. It's not an apk file installed, it's just that someone maliciously changed the suffix extension. Solution: Through the regular green platform**, you can go to the software store ** to try.

6. Due to the openness of the Android platform, there are always some software and systems that are incompatible, and this kind of software will also fail to install.

Go to Phone Settings - More Settings - Applications - Preferred Installation Location - You can set "SD Card Priority", if there is no switch, it means that the model does not support installing the software on SD card. For models that do not support installing apps to the SD card, you can manually move the large files in the phone (such as: **, **, **, etc.) to the SD card to free up the storage space of the phone.

Go to File Management - All Files SD Card - Long press the files you need to move - Cut - Enter SD Card All Files - Paste to move files to each other in your phone storage and SD card.

Why does my phone have a memory card, but I can't use the memory in the card?

It may be that the user did not set the storage path, so the data is still designated to be stored in the phone's internal memory instead of the memory card. The mobile phone memory comes with the mobile phone, and the SD card installed by the user is the extended memory. If the user does not set the software installation path, the software will generally still be installed into the phone's memory, and the user's memory card will not be used at all, so the phone will still show that the memory is insufficient.

As long as the user sets the system through the mobile phone to install the software on the SD card before the software, the mobile phone can save the memory that comes with the phone. Mobile phone memory card, different brands of mobile phone manufacturers in the mobile phone production process is different, the hardware facilities are also very different, such as the mobile phone memory card slot size specifications. Therefore, memory card manufacturers also produce mobile phone memory cards of different sizes and specifications to match the use of mobile phones with memory card slots of different sizes, and name these memory cards to distinguish these memory cards of different sizes.

Try the following:

1.Scrape the metal piece of the memory card with something slightly hard and put it in again. Sometimes a layer of dirt on the surface of the memory card can also affect the sensitivity.

2.Look at how much memory your phone supports the maximum memory, if it's smaller than the 2G you said, of course it won't be displayed.

3.After putting in the card, restart the phone and try it.

Well, first of all, take other mobile phones to try whether there is a problem with the memory card, if there is no problem, it is that the copycat mobile phone is not compatible with 2G cards. Try it with a card with a small memory. If it doesn't work, it's your phone's problem.

I asked the merchant how to explain it.

There is generally no other problem with this matter, either your imitation Apple phone is not good, or your one, your card is not good!

It may be that the phone can't read that big, try a smaller one.

I have a mobile phone that is like this, and I plugged it in a few more times to read it.

If you have no problem with the memory card itself, ask the seller what the maximum bracket charge is.

Generally, you need to restart the machine to read the card.

The problem with the phone, a bit of a good can't show the memory card.
