Google is considering to remove a useful feature from Android phones that enabled them to test network strength more accurately.
The next version of Android, dubbed as Android P, will remove the network status feature from smartphones. The change will only affect the network strength that comes within Settings, and not remove the bars from the phone screen, as per reported by XDA Developers.
To test your mobile network on your Android smartphone, go to Settings > About Phone > Status > SIM Status > Signal strength. On the Signal strength, you will see the network strength measured in dBm (decibel milliwatts) as well as ASU (Arbitrary Strength Unit) which is an integer value proportional to the received signal strength.
Users can check the network strength in a similar manner in older versions of Android, KitKat, and Lollipop, though it is a bit different in versions older than Android 4.4 KitKat.
