In Andrioid OS mobile, if you drag from top there will be many unread notifications, it is said that they are called push notifications.
But in my mobile i am getting many such spam notifications every hour like movie updates etc, which are not required for me.

How to disable them?
I have disabled an update process but still i am getting this updates.

And that's the rub. You have to find where they are coming from. For me I checked my phone and have all of 3 apps installed besides what was stock. You?

Go to Android settings|Sound & notification|App notifications and then go through the apps one by and block those you don't want nortifications from. This may take some time depending on how many apps you have installed of course...
