Phone was stuck
My phone got stuck suddenly while using whatsapp then it remained just like that for 45 minutes. I pressed the power button and all the buttons no use.I called to my number from another phone it was ringing but I couldn't see any call alert. Finally after 45 minutes it was in the recovery mode and showed a message like "couldn't restart android system" .i clicked on the try again option it worked after so much of tensions and struggle my phone started working .
I am afraid to use the phone now ,can anyone tell me what might have triggered the issue?
