Therefore, the larger the value, the better the signal, because it is a negative value, and it is always a negative value in your hands, if you feel
If you are interested in antennas with wireless base stations nearby, you can try to bring your mobile phone as close as possible to the antenna panel, so the value will grow bigger and bigger,
Then it may be very close to 0 (0 cannot be reached, and here 0 does n
antennas with wireless base stations nearby, you can try to bring your mobile phone as close as possible to the antenna panel, so the value will grow bigger and bigger,
So it may be very close to 0 (0 cannot be reached, here the 0This does not mean that the phone has no signal .)
When selecting the engineering mode in the signal strength
The UI Signal display on the android interface is implemented by sending AT commands to the communication module through RIL. For example, at + CSQ, we can obtain real-time RIL information through logcat-B radio.
So how long does the signal display refresh on the interface?
