If you are here because of high battery consumption by RILNotifier or “RILNotifier unable to establish a wireless data connection” notification. You have come to the right place; in this article, we have covered everything you need to know and have also answered if RILNotifier is safe or not.
What is RIL?
Before we explain what RILNotifier is, you need need to understand what RIL means. Radio Interface Layer (RIL) is a layer between Android telephony services and the radio hardware. The RIL consists of two components: RIL Daemon and Vendor RIL. To find detailed information about it, you can read Android RIL Architecture.
RILNotifier is an Android system app responsible for notifying other apps about the wireless network type the device is connected to. For example, if my Android phone is using an LTE network and I switch to a Wi-Fi network, the RILnotifier will notify other apps about the change. There is no other information about RILNotifier by its developers, but we think if it notifies other apps about the network type, it means that’s how apps like Google Play Store identify the network type and ask you to download apps over Wi-Fi instead of a cellular network.
Is RILNotifier Safe?
As mentioned, it is a system app, and most Android devices have it; in some devices, it’s named Service mode RIL. Some people think RILnotifier is Spyware, or some even think it means their device has been hacked and it’s being controlled by hackers.
All of these are just myths; when a non-tech-savvy person finds out their list of system apps, they start assuming things based on the name of the app. For example, Samsung devices have a system app called incallUi, it contains the user interface of the dialer app, but some people think it’s a type of spy app used by their partner for monitoring their calls.
Permissions Used by RILnotifier
