I keep getting the error message on my new Samsung S7 edge when I insert a new SD card it keeps coming up corrupted ? Please help !

Question edited for clarity.

This is always because people buy modern SD Cards that are far too bit for older cameras. The maximum size for an SD Card is 2GB. Also you must format the card inside the camera.

Definitely Yes! First of all, you should stop saving any new files to your Samsung smart phone (or SD card) or taking new pictures.

Then find some photo recovery software from this site Best Computer Software, which are able to recover deleted or formatted photos from cell phone, digital camera, memory card and SD card etc.

Digital Photo Recovery for Windows

Digital Photo Recovery for Mac OS X

Here are the steps:

Step 1: Download and install the Digital Photo Recovery Software.

Step 2: Connect your Samsung smart phone (or SD card, memory card etc) to your PC or Mac.

Step 3: Scan the source drive where your lost pictures located.

Step 4: Recover the lost pictures and save them to another drive instead of the source drive.

Absolutly your samsung phone still locked my friend. You must unlock it using samsung GT-E2550 unlock code first. After you insert samsung unlock code in your phone then you can change your sim card as many as you like.

The D53 uses SD cards, not SDHC cards. You'll have to stay with cards 2GB and smaller.

More then likely when the screen froze up on you it it had a little power glitch as well, nothing serious but it did wipe out some of the information in it's memory about the SD card.Power the unit up and let it come up with the error, then use the reset button. Might be hard to find since it's just a little hole with the word reset around it, using a paperclip push in the button and see what happens. If the error comes up again then i am thinking that you will need a new SD card. Quick test for this, remove the SD card from the gps unit and try rebooting, it should come up with an error, no SD card or no map, stick in an SD card from another device, 2gb, see if the gps can find the card, it should give you an error that says unable to find maps. If you get these error codes then most likely the gps unit is fine but it pooched your programs on the SD card.
Hope this helps

No, I was looking for free technical advice.

If there are sd card error, you cannot format your sd card. you may get messages like

"No SD memory card inserted" messages appears when using digital cameras,
"A media card hard been inserted that contains errors. Do you wish to repair the Media Card now?"
You can read the files on SD memory card, but you cannot write new files or you cannot edit files on SD memory card,
"Access denied", when SD card is corrupted or broken,
