So, I installed the The Avengers Live Wallpapers for my Android Phone since it was on Google Play’s (previously known as Google Market) feature list
Almost immediately after installing it, I could see annoying little nag screens on every screen unlock, like the one you can see in the screenshot below.
Which is pretty nasty way to convince me to buy the pro version. I uninstalled it right away. I highly recommend everyone not to install it on their cell else you’ll have to uninstall it later.
Update: I have posted a review on Google Play, you can read it here
