Mickeymaus Posted July 27, 2021 Share Posted July 27, 2021 I have a Samsung Galaxy Tab S7 Plus with Android 11. In the tablet is an SD Card. Wenn I connect the tablet to the computer via USB I have read and write access at the device memory. At the SD Card I have only read access. Does not make sense to me. But I couldn't find a fix so far. In the tablet the SD Card works problem free. Any ideas? Sure I could take out the SD Card and connect it with a card reader to the computer. But this is not what I want. I didn't have this problem for instance with Lollipop. Link to comment Share on other sites More sharing options...
sammieuk1 Posted July 27, 2021 Share Posted July 27, 2021 On the adaptor you plug into your PC there is a slide switch for read/write or your card is not mounted on your tab or the card is the wrong size ie to many gb???? Link to comment Share on other sites More sharing options...

The SD Card has no problem. Works problem free in the tablet and is there all the time. I guess it is more a thing with Android 11. I looked on the Internet and saw that I am not alone with this problem but couldn't find any fix. Google never cared much about SD Cards. Never forget when they suddenly under Android 4.4 implemented write restrictions for apps when the target was an SD Card. Endless users including me had a big problem. In Android 5 they partially reversed this then. It does not really make sense. You can write to the internal storage of the tablet using a PC. But writing to the SD Card is blocked. You can read it and can copy the files to the PC. But I need to copy files from the PC to the SD Card. Link to comment Share on other sites More sharing options...

And you get asked if the PC should have the permission. But this doesn't explain why there is a write permission for the internal storage but not for the SD Card.

mtls2005 Posted July 28, 2021 Share Posted July 28, 2021 (edited) Oops. Scoped Storage Google, read. In Android 10, and 11 I did notice that the SD card gets formatted with some matching app storage directories. DCIM, Music, Pictures, etc. for example. Can you write to those? Probably not. https://www.xda-developers.com/android-11-all-files-access-permission-form/ Product Manager...

Will try in the evening and let you know. But even if this works it does not help me. And at the main memory there are no restrictions. Link to comment Share on other sites More sharing options...
Mickeymaus Posted July 28, 2021 Author Share Posted July 28, 2021 (edited) My goodness. I found the problem. I tried to rename AVI files on Android from the PC. This doesn't work at the internal storage and at the SD Card of the tablet. I can delete them on the Android device or copy them to the PC. But I cannot rename them. If I copy AVI files from the PC to Android I get the message shown in the attached picture. So it is not a permission problem. Android natively doesn't support AVI, WMV or some other media file extensions. Not sure what this has to do with a simple rename of the file name. There is no problem to rename such files in Android directly. Only if you try it from the PC it doesn't work. It doesn't really care about the codec of the file. If you change the extension from AVI to MP4 in Android for instance you have free access from the PC. This is Google... Gets on my nerves... Or does Microsoft create the problem? Could be. ????

The only thing I wanted to do was to rename video files that were on the SD Card using the Windows fiie manager on PC. And this didn't work. But I could copy them to the PC or delete them on the SD Card using the Windows file manager. Didn't make sense to me. Then I tried to copy just for test purpos an AVI file from the PC to the SD Card and then I got the Windows message. Then the problem got clearer. I think too that the problem is caused by Microsoft. AVI and WMV were both developed by Microsoft and both had the same problem. I see it as a Microsoft bug because just renaming the file on the SD Card shouldn't be blocked. Doesn't make sense. Sadly this was the first time that I accessed files in this way on this tablet with Android 11. And this combination of AVI files and not being able to rename them didn't make sense. I renamed video files on the main memory of the tablet but they were MP4 and so it worked. I didn't care about the file extensions and so I did not realise that they were AVI in one case and MP4 in the other case. Typical for Windows - the system itself keeps you busy... ????
