Mobile oxygen refers to the "Oxygen" in the mobile phone signal strength indicator, which is usually a green oxygen icon on the mobile phone. This icon indicates the strength of your phone's signal, also known as the quality of your phone's signal, sometimes referred to as network coverage. The common signal strength is 5 bars, where 5 bars indicates the best received signal, and 1-2 bars indicates the received signal is very weak.

The quality of mobile phone signals has a great impact on our daily usage experience. If there is no signal or the signal is too weak, both call and network speed will be affected. In addition, the time the phone takes to search for a signal will also have an impact on battery life, because the phone needs more power to search for weak signals. Therefore, it is very important for us to check the cell phone signal strength oxygen icon.

Sometimes we may encounter a situation where the mobile phone signal is very poor and we are unable to change the mobile network service provider or location. In this case, we can try the following measures to optimize the signal strength: preserve the battery life of the mobile phone, look for signals in open areas, keep the mobile phone at a flat surface away from the detector, close unnecessary mobile phone applications and multimedia content. These methods can help you optimize your cell phone signal and improve reception quality and speed.
