I did the same , but it didn't work. The display doesn't come. It says "optimizing apps" and repeats switching off and on. What if I take my phone to repair? Will they be able to repair it?
Oh I'm sorry I've not mentioned it. I did android system update.It was coming all the time in my notification panel and troubling me.So I tried to update.
I tried to update my samsung galaxy grand prime phone.But it stopped in the middle.Now it keeps on switching off and on repeatedly.Even the display doesn't come.What should i do?
