Everyone (especially sighted developers!) should try enabling a screen reader on their phone once in while. Of course it's great for finding accessibility bugs, but it's also a cool trick to be able to read emails and stuff without someone being able to look over your shoulder.
If you want to try the Android screen reader, turn on accessibility with Settings -> Accessibility, TalkBack On. Then, tap a control once to hear what it is, then double tap to activate. (This is very important to know, or else you won't be able to turn TalkBack off again.)
Tip: don't try TalkBack in your office, or you will rapidly drive your officemates crazy.
I often have to help a family member who is blind. Trying to use a phone with Voiceover or Talkback is the most horrific experience. Each button or key press takes 3 time-sensitive taps, while it speaks the contents of that button/key in a robotic voice.
I say this as a sighted person, but is this really the best we can do? If you're blind I can imagine how important it is that it works at all, but it still sucks.
Annoyingly, what my family member really needs for their use case is an old-style phone with tactile keyboard - if it weren't for the fact that they also need to voice dial, hear who's calling, and hear incoming texts.
