I have a samsung chromebook plus 32 bit ARM based and now it has plastered on the screen a message that says: "Security Updates Ended. Update your device" The message cannot be removed. If I click on it, opens chrome and sends me to the Google store (effing commercial). The laptop runs like a charm (I replaced the battery) with termux installed. It has a great touch interface with a stylus that will break If I try to install other OS on it. Google way to obsolete this things starts looking a lot like Apple. They want to kill their old devices with a thousand little cuts. I just want to remove the goddam message and for Google to leave me alone. Good luck with that.
