The Android M developer preview was launched 2 days ago at Google I/O 2015 in San Francisco. Senior vice president of products at Google, Sundar Pichai introduced the conference and said that the company had “gone back to basics” with the new version of Android. Android M brings more stability and usability improvement, while Lollipop provide a brand new design and aesthetic.

Android M brings siz major new features, some are useful, while others are just eye candy to have. Let’s go through each of them.

1. App permissions

There had been many discussion regarding how user can adjust the type of permission should be carry out. Those who had used CM 12.1 build would likely know that the built-in privacy helps user to control application on the mobile with granular controls. Now with Android M, users now will be able to choose to accept or deny individual permissions as they see fit. In addition, permissions have also been simplified.

2. Web experience

Google has been exploring trends in the way of web content based on statistics that they have collect from various source to help improve user-experience when interacting with websites and apps. “Chrome Custom Tabs is a new feature that gives developers a way to harness all of Chrome’s capabilities, while still keeping control of the look and feel of the experience,” said Burke.

Google are just overrating this features, what a waste of time. Why not they just sit there and think how can extension be port over from desktop version of chrome. Such as how many times do you see advertisement popping out of all this web pages. If they are seriously wants the best user-experience, they should make an ad-blocker and reduce the installation size of chrome on mobile and tablet.

3. Fingerprint support

Google will “standardize support” for fingerprint scanners on phones running Android M. The new functionality will allow fingerprint scanners to be used not only to unlock phones, but to make purchases shopping in real-life or within Play Store apps.

Another waste of time introducing a features of similar to Apple. What’s wrong with Google and what are they really thinking. How is it that fingerprint support is part of the new features when existing phones less than 10% of the phone market for Android does not have fingerprint capabilities built on them.

Do take note the market adoption for Android Lollipop is not one of the best rated. If we use the future as a references, again less than 5% of the market would even support this features.

The rest of the features such as mobile payments, app links and power and charging are really just features which seems cool to have but its feasibility always heavily relies on the mobile makers such as Asus, HTC, Motorola, Samsung, Sony and etc. If they do not implement these features you will not be able to enjoy it either.
