Being a motorola fan I bought the fire xt 530. Its price is lower than its competitors htc wildfireS & samsung ace & also has 800mhz processor. It also has a front camera unlike others.
There are 2 problems with this phone. 1st is the camera quality which is poor as compared to others. Even a sony phone having 2megapixel camera is better than its 5 megapixel with flash.
2nd is the internal storage. One cant install all apps from android market as every app cant be moved to SD card. When the internal memory gets full less than 15mb is left, the phone starts to hang a lot.
Now I keep onlly limited apps on the phone & it works just fine.
