Hey there, you might be wondering what are the best free and open source Android apps alternatives to most of the applications and services available on your Android powered device. As you know already, Android development is under the control of Google – the king of online behavioral tracking and specialists in targeted advertising.
According to Wikipedia, Android OS is actually open source but in ‘most’ devices it comes with proprietary components embedded with it. What does that mean? Is it really open source?
The answer is a big ‘NO’!
Well, I was also wondering the same and was looking for free & open-source alternatives to the conventional Android operating system, the apps and services, etc.

Now, here are some free open source apps for Android –
Free and Open Source Search Application
First of all, the default Google Search app can be replaced with DuckDuckGo.
