Crop factor is the ratio of the dimensions of a full frame camera's sensor (36 x 24 mm, which equals the frame size of a 35 mm film) and the dimensions of the image sensor of the device. The number shown is the ratio between the diagonals of a full frame sensor (43.3 mm) and the sensor in question.

Similar to the CPU, the GPU consists of processing units called cores. They handle the computation of graphics in various applications. Information about the width, i.e. the horizontal side of the device when it is used in its standard orientation. stand-by time is the longest time a battery charge will last, if the device is not used but is constantly connected to the 3G mobile network.

Above the screen, an ambient light sensor, proximity sensor and a wide-angle 5MP front-facing camera are either side of the earpiece (within the speaker grille). The main microphone is placed under the bottom speaker grille.

In any case, we're looking at an extremely well-made device, with premium written all over it. The Sony Xperia Z1 Compact is probably the only smartphone that comes close in terms of build and finish. Controls and handlingThe L2 (level 2) cache memory is slower than L1, but has a larger capacity, instead, which allows it to cache more data. Just like L1, it is much faster than the system memory (RAM). If the CPU does not find the data needed in L2, it proceeds to look for them in the L3 cache memory (if there is such) or in the RAM. Information about the dimensions of the image sensor used in the device. Usually cameras with larger sensors and less pixel density tend to provide better image quality despite the lower resolution. When HTC launched the One in 2013 its integrated dual speaker and internal amplifier setup, dubbed Boomsound, blew rival handsets out of the water with its audio quality. It's not a huge issue though, as with a steady hand the HTC One Mini 2 is capable of taking some nice shots.
