I just received it with a 32GB Transcend TS32GUSDHC10E card. The phone does not recognize the SD card, it asks the loop format. Looking at the net, I realized that I was far from alone in this case, with various micro SD card designs. I contacted the Motorola service who confirmed that there was a micro SD card recognition problem. For now they do not know if it is a software or hardware problem. They advised me to wait until they publish a Firmware Update if ever the problem turned out to be software or SD card to try until you find one that is recognized by the motorcycle g or remit the device to Amazon ... In short, if you want to use with a micro SD card, be aware that it is the lottery ... Since I bought only for its micro SD slot, I'm super disappointed Motorola on this one.
Edict 16/07: I just received the 4.4.4 update my card and actually transcend 32GB not working is now recognized! To see if it takes time. By cons since my first review, I have a dead pixel problem: it remains green when the background is black. So I was the rating to 3 stars instead of 4 because of this screen issue because it's getting a lot of problems for a new phone!
Edict 11/08: if my Transcend 32GB card is recognized for the maj 4.4, in practice it is unusable. I never managed to read more than a few minutes video: I always end up getting an error "SIM card removed". In addition, the Motorola Service is bad, I am a lot of promises and no sticks. Bad experience with this phone and this brand, I recommend. I descend to my 2 star rating as initially.
