Wow, you'll go buy an android simply because you can't figure out how to use your iPhone?
That's pretty sad, but do what you will, no one here will try and stop you.
If you'd prefer to solve your problem though.. I suspect you have a Photos widget in Today View. Removing it would be a pretty simple solution.
Unlock your iPhone and get to your Home Screen. Swipe right until you get to Today View. You should see the same thing you see when you swipe right on your Lock Screen. Only from here you can swipe all the way to the bottom and select 'Edit'. Once you do that, all the widgets will start wiggling. Scroll back up to the top where your Photos widget is, tap the little minus sign and remove it.
