Hello. I have this smartphone since couple of days. Today I bouht a microSD Card TDK 16GB. The phone found the card, but I was unable to read or write on the card. I tried the card with MicroSD Card Reader and the card worked fine. I also tried to put my old MicroSD Card from my old phone on the Xperia L. The old card is Apacer 8GB with two partitions. The first is for storage and the second is for Applications linked with Link2SD. The Xperia L found only the second partition (for the apps), but I was able to write on the card and also read from it. I tried to format the new MicroSD Card from Windows and from the phone - no results. Then I updated the phone from PC Companion. There was a new firmware, I think. The Android version is the same 4.1.2 Jelly Bean. The SD stared to work on the phone. I can read and write on the card. I decided to install iGo navigation. All ok, but when I put the maps on, the application starts to crash and says, that there is an error in the maps. The maps however work fine, because I have tested them on my older phone. Then I installed iGo on the internal memory of the phone (SDCard0 - that are saying ES File Explorer and Astro File Manager for the Internal Memory and the SD Card is SDCard1) and the Navigation now is working fine. Is there a problem with the phone or with the MicroSD Card? Separately they both work fine. I tried the MicroSD Card with other files - music, pictures, videos - all is working fine, but I have problem with the Navigation. What do you think? Is there a problem somewhere? Why I can't run iGo from the MicroSD Card? Is this a Software or a Hardware problem? Is the problem from the Phone or from the MicroSD Card? Is there a problem at all?
