My Samsung Galaxy S3 is almost three
years old, still running fine, but it is not getting attention for an upgrade
to CyanogenMod-12 based on Android-5.0
Lollipop. So I've decided
to upgrade it. (Update: S3 started getting CM-12 nightlies on 2015-05-02.
If I had been patient I wouldn't have had to do this, but the S3 even so is
not exactly a spring chicken.)
After checking out the machine on the stock image I installed CyanogenMod-12
based on Android 5.0
Lollipop. Unlike previous phones, this one is not
subsidized by a carrier and lacks customer loyalty enforcement, i.e. it has
an unlocked bootloader.

To set up the machine the way I want, I've had to do some hacking, which is still in progress.

Keep personal records. I have hypertension and I need to monitor my blood pressure. I found it very useful on trips abroad to record dutiable and taxable items as purchases were made. I didn't purchase or create a dedicated application for this: I use generic Linux tools, a spreadsheet program and a flat file editor.
Play games. Other smartphone families also have games, and I'll leave it to the reader's judgment whether their possibilities or Android's are more numerous and more interesting.
Map navigation. This is particularly likely to be done outdoors in bright sunlight. While I mainly use Google Maps, a very nice addition would be a map program that could display USA National Park Service maps, and US Army Map Service maps.
Photography when the
camera is too obtrusive or not in hand.
PIM/PDA functions: contact list and calendar. Most people include e-mail in the PIM suite, but I use webmail on my own server.
Communications. While for some people the main emphasis of the cellphone is communication, I emphasize other activities; nonetheless, communication is important to me, in these categories:
