The 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. With the exactness of the colour representation, which we determine with the CalMAN software and the spectrophotometer, the deviations are quite large and in the greyscales a bright blue cast becomes visible.

The average temperature for the upper side under maximal load is 36.6 °C / 98 F, compared to the average of 32.7 °C / 91 F for the devices in the class Smartphone.A80 Pro’s Sony® 8MP front camera enhances your facial features even further with clarity and delicacy. It automatically identifies ages and smoothens different skin tones depending on gender.

The loudspeaker is a device, which reproduces various sounds such as ring tones, alarms, music, voice calls, etc. Information about the type of speakers the device uses. One of the main characteristics of the cameras is their image resolution. It states the number of pixels on the horizontal and vertical dimensions of the image, which can also be shown in megapixels that indicate the approximate number of pixels in millions. Wi-Fi communication between devices is realized via the IEEE 802.11 standards. Some devices have the possibility to serve as Wi-Fi Hotspots by providing internet access for other nearby devices. Wi-Fi Direct (Wi-Fi P2P) is another useful standard that allows devices to communicate with each other without the need for wireless access point (WAP).

The camera is quite weak in low light and high contrasts, but you should not expect too much from a very cheap phone. In the lab with very good exposure, the autofocus has clear problems, the contrasts also vary depending on the image area, but overall they are not that bad. The camera no longer recognizes anything at 1 lux illumination Design Information about the dimensions and weight of the device, shown in different measurement units. Body materials, available colors, certifications. Width Audio file formats/codecs Mobile devices support various audio file formats and codecs, which respectively store and code/decode digital audio data. Audio file formats/codecs Sensors Different sensors measure different physical quantities and convert them into signals recognizable by the mobile device. Sensors The storage configuration is very meager: Just 16 GB of mass storage and 2 GB of RAM are installed. The user can still use just under 10 GB of data storage, so you have to think about which apps to install or whether to store photos in the cloud. The storage can be expanded by up to 128 GB via microSD, but the smartphone did not work with all microSD cards in our test.
