Change my SD card to a bigger space, and my phone it says,SD card blank.

This is a very common problem, apps are getting updated and bigger every day... I actually deleted facebook from my phone because it was also using the battery more than my screen! If you have an android phone you can put your downloaded programs on the sd card through app manager. And you can always put a bigger sd card in, but this will only help so much because only a portion of the program actually goes onto the sd card.

you may have to move some things around.I would go get a bigger SD card or one of the same size. Its not hard to change the sd cards out

By memory you mean storage I presume. You can either try installing bigger flash storage (not recommended), use SD cards, or simply delete old apps and pictures that you don't need anymore.

You need to setup your phone settings to use the SD card instead of phones internal memory. Should be under the settings menu, look in the apps section and storage to find what your looking for...Change the defaults to use the SD card and NOT the internal memory.

Hope that helps.

You need to clear space on your SD card either by deleting some apps, pictures, or music. Or you could get a bigger SD card.

From what I have read online, something has changed so you cannot move apps to the Micro SD Card anymore. You may have to clear some space.

I do not have a S4 Mini but a the bigger S4, and I use CleanMaster to keep things clean (be sure not to delete your music or pictures)
Some phones allow you to move apps to the SD card.

I beleive the memory that it can read is only limited by the software you are running such as windows XP sp1 and 2 can recognize upto 2gb SD cards but keep in mind that SD cards only go to 2gb anything bigger than that are SDHC and are the same size but designed differently so the reader must be able to read SDHC format. Note if your hardware is capable of reading SDHC cards and your software limits your ability to use anything bigger than 2gb you can still insert and use upto 2gb of space on an SDHC card that is, say 16gb so that is how you can tell if it is hardware or software that limits the use of an SDHC card.

Hi, i guess you should use the manual to change the micro SD card,in other not to damage the phone.
