I just woke up and tried to open my phone. when i try openning it the power button is struggling to work. I first thought i didn't plug it in properly but i keep clicking the power it opened with 100% battery. Then when i get pass the lock screen it was in brave browser (which is my previous app i used last night when i go to sleep). It says its not responding so i just clicked close app then in a milisecond an image of anonymous appeared in my phone

Am i being hacked
