Security of Android devices has been a nightmare since the first days and the biggest reason being is that users don’t receive latest security patch updates regularly. Precisely, it’s your device manufacturer (Android OEMs) actually who takes time to roll out security patches for your devices and sometimes, even has been caught lying about security updates, telling customers that their smartphones are running the latest updates.
XDA-Developers reporting that Android P might get a new feature to the stock dialer app commits showing a part of a new set of a new patch-set that were added to AOSP from a Sony Engineer. This little new feature would allow you to block all incoming calls from any number that isn’t in your list of contacts. Text strings found in the commits suggest there will be option to block numbers based on the following criteria.
Googles tries to improve the security and data privacy in the upcoming Android P release, right now after the app gets the permissions to use the microphone or camera the app theoretically can ‘spy’ on you secretly in the background, this will be changed.
According to a few commits, it appears that some carriers are pushing for the ability to hide the signal strength in the next version of Android. Currently, the signal strength can be found under “Sim Status” in the settings menu. This is the actual numerical signal strength measured in dBm or asu: the lower the dBm number, the worse the device’s network signal is.
While most users wouldn’t care to look at the exact dBm value of the signal strength, it can be a useful number when comparing how multiple devices on the same network perform. Your device’s signal strength might be incredibly important to detect the call quality, data connectivity & speed. Looking at the dBm value when using your phone in certain areas can be a useful way to see how well your new device fares on the network.
