…the flat world lollipop “No texture, or shadow”

• Unfortunately, that what lollipop is already about. Layers of UI components, differentiated by depth (Shadows). It is no way flat. It is also called material design, where they try to bring real world depth to the digital world.
• In this world design is not just colors and shapes, but also interactions, transitions, ripples etc. It is more about being lively and with life.

Suggestion: Try using Google to search for material design.

Android Home screens still doesn’t rotate when you turn the phone

• I don’t know any other smartphone OS which does it either. I would love to see some home screen examples on another platform which does this.

Quick settings require scrolling.

• So does your article, or unlocking an iPhone. Scrolling is nothing but swiping your finger. Did you know the settings also rearrange based on what you use more, so that your most used option is on the top?

“Hey, can I borrow your phone”

• I am sorry, but Android phones are not just used in the Glasshouse retail stores in Silicon Valley, but in the villages of Russia to slums in Mumbai. In fact people with family and kids may occasionally share their phone with their kids or spouses. So, yeah people borrow phones. Just like iOS borrowed the notification center.

…stacked-deck-of-cards effect of Safari on the iPhone

• Which is again borrowed from the stacked deck of cards effects on Chrome Mobile. So is it even then?

Duplication of Apps is still goofy.There are still two settings apps (called Settings and Google Settings) and two email apps (one for Gmail, one for other accounts). Goofy.

• You’re pretty amusing. Google is not equal to Android. Android is a platform, and it is quite open. Google apps compete in the same level like any other app developer. Google settings is the settings for Google apps. System settings is settings for the system. Angry birds has its own settings. So does Tinder. Unfortunately, they’re not combined into one Settings app. Hey, it actual sounds like a million dollar idea. A settings app to tinker settings of all the apps in the world. No duplications, super ease of use!
• Same goes with Mail clients of messaging apps or camera apps. But having two map apps in a phone might be a little funny.

Face unlocking

• Did you know that you can enable “Liveness check” which will make sure you’re face is “live” when you unlock?

I can go on on each point you tried to make here. I will just stop here. If you want to find some grayer pastures, you can visit this Reddit thread about this article.
