I use Samsung A30 since July 2019. Since yesterday evening, my power button has stopped working. I can press it but screen doesn't shut on and off. Since midnight, options of power off button, restart button and emergency button is frequently popping up in my screen automatically. These are the options which normally pops up by holding power button.
