At present, on Android, it is possible to consult the strength of the network signal, expressed in dBm from the Settings application. This only makes it possible to check the signal strength in real time, to ensure that the smartphone can be used in optimal conditions. In addition, this option allows users to compare the network signal of the various operators by themselves. We can therefore easily understand why some operators dream that this feature disappears.
Android P: consumers will no longer be able to check the network signal strength in the settings
In the United States, several operators are already managing to hide the strength of the signal to smartphone users they sell under their brand. The operators in question should be thrilled with the next version of the operating system, Android P. Indeed, members of the XDA forum have recently discovered a surprising change in the code of the Android Open Source Project . This change could allow operators around the world to hide the strength of the signal on any smartphone with their SIM cards by editing the vendor.xml file.
The API allowing third-party application developers to measure the true network signal strength of any operator will not be changed at all. This new feature will not completely prevent users from checking the strength of the signal, but will make the task much more tedious. It is possible, however, that signal strength measurements will also be blocked at the PLC level in the near future. As a reminder, Android 9.0 P is expected for 2018, a year after Android 8.0 Oreo. The developer preview should be released at the end of winter before the Google I / O in May 2018.
