If your phone has provision for an SD card, then, you just might be in luck.

Step 1:
Insert an SD card and confirm that your phone can truly see it and in turn access it.

Step 2:
Navigate to Settings, then click on Apps/Applications
Once this opens up, scroll to identify app you downloaded and installed on your phone; especially the ones with high ~Mb sizes.

Step 3:
Select or click on one of these apps. A page opens where you'd notice app info
**Force stop
**Uninstall
**Clear app data
**Move to storage/Move to SD card

Step 4:
Click on "Move to SD card/Move to Storage"

Do this for every app you installed and get them transferred to the SD card.

This will free up internal memory space so you can install new apps on your phone.

Slide the write protect tab forward to remove the write protection. You cannot format it while it is write protected. Formatting will erase all data on the card. Install the card into a Windows or MAC and wait for the device to detect and mount the card. Use the appropriate procedure for the machine to format the card. See this procedure for additional step-by-step operations after the write protect tab has been moved.



How to Format an SD Card

Hi Dianne
-First off make sure what 'formatt' the Samsaung camcorder you are using was recording in. The most common 'formatt' currently being used by camcorders is AVCHD.
-You then need to confirm that your Mac has a version of iMovie that is compatible new enough to recognize this formatt (if your computer was purchased in the last 3 years it should be)..., if not you will probably need to install a newer version of this software.
-If your Samsaung video files were recorded onto SD cards vs the cameras internal memory..., it is easiest to remove the card and then download to the computer..., via a card reader or via the computers 'built in' SD card reader.
-The important thing is to create a folder on your desktop and drag the files you want to download to this file..., do not try to import directly to iMovie (if you try to import directly to iMovie..., this is where problems often occur).
-Follow these steps and you should have no issues.

Its most likely your Micro SD card thats faulty. If its a Sandisk of Kingston then theres a 12 Month warranty on them but if its one of those cheap no name ones they are a complete joke and will continue to corrupt everything put on them. Invest in a good brand one.

hey you cannot transfer contact in sd card, unlike the picture images etc. but phone contacts you cannot,

If your talking about your sd card lets say 4gb now says something like 92kb free, like all your memory just disappeared, then try this program it worked for me.
