After the latest OS release Android 12 Aggressively Limits Background Apps that might be causing trouble in your phone’s performance. The new feature is named “the Phantom Process Killer”. This is an Android 12 feature that monitors all of the system’s background child processes.
And will start killing them if the amount goes over a certain number—32, by default. That 32-process number is system-wide, not per-app. Meaning that by default, Android 12 only allows users to have 32 “phantom” processes.
Google defines a “phantom” process as a child process of an application running in the background. 32 phantom processes are quite a lax limit for the usual Android user. and even heavy users of their device are unlikely to suffer serious issues from this new feature.
Android 12 Aggressively Limits Background Apps to Speed up phones
it’s possible that the Phantom Process Killer could improve performance and battery life.
Most users don’t restart their phones all too often, either. So some users with a lot of apps installed may see improved responsiveness and battery life from this change.
It was discovered that a mechanism to monitor forked child processes started by apps and kills them if they consume too much CPU if the app is in the background (via Mishaal Rahman) was introduced.
It also limits the number of child processes that parent processes can spawn to 32. Which greatly limits the number of operations an app can complete in the background.
The Phantom Process Killer was first discovered by developers on the Android terminal emulator Termux. Android famously runs on top of Linux, and surprising as it may be, some folks actually use Android devices as full Linux systems.
Let see what the new android update has to offer and what are the user reviews about it in the coming days. But so far things seem pretty neat.
