It all started after I updated the phone to the new firmware. The new UI was slow and laggy. Sometimes when I used to pick up the phone speaker used to be switched on.
From a few days, the volume on the screen just showed a horizontal bar and not the actual volume UI.
3-4 days ago Chrome crashed and 2 days ago Google search and Google now crashed. I installed Amazon kindle app for Android last night but that too crashed in the morning.
And from afternoon, the phone itself crashed.
How do I get my phone back to life?
