Once suddenly stopped connecting to the mobile Internet, I had to turn it off and on. For some reason, sometimes Bluetooth turns on by itself. Otherwise, there were no firmware bugs and physical assembly defects. Pros below: - Good, bright and juicy AMOLED technology screen. - Plastic case (less fragile than glass on both sides on Galaxy A3) - Removable battery (also convenient) - Fast enough for the price - Shell TouchWiz has become much more beautiful compared to the Galaxy S4 mini - Dual SIM cards Has some cons - Only 8 GB of internal memory (storage) - all the necessary applications could not be installed, I had to refuse to install the least necessary ones. - the camera does not have autofocus - it is impossible to photograph objects too close - the camera itself is average in quality = there is no backlight for the touch buttons "Back" and "Apps" (there is a backlight on the Galaxy S4 mini).
