How to get app upgrades free?

[Day]

Is there any way I can get upgrades for apps for free? Like let's say there's a trial and it is asking you to upgrade to the "pro" version, how could I get that for free? I'm new to the Android community so I'm a n00b.

What app are you talking about? Usually they are always free, if you already have it downloaded.

Root your Android and install the games yourself, cracked version ofcourse so don't download and install whatever. It's so easy to get malware on an android.
