Ask HN: Any hobby ideas using an Android-based smartphone?

I finally arrived at the decision to purchase a smartphone.

I decided to go with an Android-based model, most probably those from Nokia, because they are stock, and fit my budget.

Why Android and not iOS?

Because, iOS ones are crazily expensive. Though I acknowledge that iOS-based phones deliver a bigger bang for the buck; on the quality of hardware, tight integration with software, vastly superior user experience, longer time-frame of support for software updates, and a much higher resale value.

Also, Android-based phones, especially the stock ones, afford tighter integration with the Google ecosystem of services, something which iOS phones don't seem to be decent with.

I am a person who is retired, uninterested in continuing to program, detests computer games, likes to stay in-the-know about local, national and global happenings, doesn't much like the outdoors, and not very financially well-off.

Now comes the question.

What use could I possibly put that Android-based smartphone to, to have some kind of engagement, say, a kind-of hobby?

I am from Bombay, India.
