  1. Installed a 32GB SD card into my Samsung Galaxy S3 mini and formatted it as directed on this page. There is actually only 29.33GB of usable memory even after formatting the card

    1. Hi There,
      I'm so sorry if this articles can't help you.
      After reading your problem, you can try this tips:
      1. Try to format your SD card on your computer. Will it have the same result or not?
      2. Or you can try to use a third-party app such as ES File manager that will be able to report the actual space of your SD card and will also allow you to remove hidden files and folders. You can get if free through Play Store.
      However, thanks for your visit and comment.
      Hope it helps :)

    2. it is the clueless salesmen's fault...
      They calculate hard drive sizes using base 10, where 1000 bytes equals one kilobyte. But computers do everything in binary (base 2), where it takes 1024 bytes to store a kilobyte of data. In addition, the computer’s OS uses part of the drive for a directory to keep track of the actual data. As a result, the usable capacity of a hard drive is typically 90 to 93% of the advertised capacity.
      If you want to prove this to yourself, take the 64 GB as an example. By the hardware maker's definition, one GB = 1000 MB and one MB = 1000 KB and one KB = 1000 bytes. So 64 GB would be 64 x 1000 x 1000 x 1000 bytes (64,000,000,000).

      Now, divide 64,000,000,000 by 1,024. Divide the result by 1,024. Divide once more by 1,024 and you will get 59.6046447754. Some space is also utilized by the directory/tracking function of the formatting system, so that would account for the difference between the number I calculated above (59.6 GB) and the available capacity of a "64 GB" = 59.2 GB)

      Thanks for coming and your willing to share your useful knowledge here :)

  2. Will my contact info be deleted when I reformat my sdcard?

    1. Hi There,
      Thanks for visiting my blog and leave your thought here.
      When you format your SD Card means you will be delete all files inside it. Due to this reason, before you formatting your SD card better if you backup your files first to another storage available, such as your computer or else. Once you finish formatting your SD card you can restore the required files into it again.
      Hope it helps :)

  3. I have made SEVERAL calls & visits to my carrier & had 'live chat' with tech support about the length of video record time on GS3. Before I purchased a sd card my record time was only 33.25 mins. Purchased sd card...still only 33.25 mins. Have formated & recorded again; STILL ONLY 33.25 MINS. SO FRUSTRATING!!!! My iphone had capability of recording for up to 4 hrs with no purchase od sd card. Was told this phone could record up 3 hrs with 64gb sd card (which I have) still 33.25 mins HELP?!

    1. Hi Gigglez Bailey,
      Thanks for coming.
      Well, have you ever use another apps then compared the times? I've read on many forums, there are so many users who have the same problem with you--even they have a lower time than you--and unfortunately, I didn't find the one who have managed to fix their problem. And, yeah you right, iPhone has Cycorder which will allow you to record as long as you have the space and battery life.
      Finally, I'm so sorry if my answer is not satisfying you. Hope there will be developer who will create the similar apps for Android.

  4. I have a 2GB card from an older Samsung. I have been using it with my SIII for about 5 months now. It recently did a system update and erased everything on the card.

    Not the end of the world but now I cannot use the card. I try these steps to format it and just tells me "Blank SD card"

    Any ideas?

    1. Hi SkinTicket,
      Thanks for coming.
      Can you use the card on your PC or another phone?
      However, try to go to Settings> Developer option > tick Protect SD Card box then see whether it helps :)
