It often happens that a completely new phone you have purchased does not behave the way you would like it to. For example, it works slowly, responds for a long time to pressed keys, does not immediately launch applications, etc. In some cases, this is a consequence of a defect, but often the firmware plays the main role.
Firmware refers to all hardware settings, as well as software that are stored in the phone's non-volatile flash memory. This memory is one of the most important. In English, this concept is written as firmware.
If in computers memory and operating system are separated from each other, then in a mobile phone they appear as a single whole. For this reason, the firmware is not only a set of settings, but also a set of software tools that are part of the operating system.
The role played by firmware in a mobile phone is enormous. The communication of the components that make up the hardware part of the device with its cellular module is carried out precisely with the help of firmware. As a rule, it is developed for each specific phone model. However, in some cases, one firmware can be used on phones located nearby in the model line. Such examples are the Nokia 6250 firmware, which can be installed in the Nokia 6210 to get the 6250 functionality. Similarly, the Sony Ericsson K750i "turns" into the W810i model.
It is the firmware that plays an important role in the "glitches" of a mobile phone. Often, when releasing a new device model, manufacturers do not properly test the software component. This, by the way, is often the result of high competition and the desire to launch sales as soon as possible. Especially serious flaws are found, as a rule, in the first versions of firmware.
The phone flashing process can provide the following benefits:
- correction of mistakes made in previous versions;
- software update or adding a new one, the emergence of new themes, melodies, images;
- support for new headsets;
- increase in performance, battery life, signal reception quality, etc.
