When the ringtone is not the part that works
There is a large gap between a phone that technically supports accessibility features and a phone that has been set up to use them. Android ships with live captioning, flashing alerts, hearing aid support, mono audio and adjustable vibration, and almost none of it is on by default. The apps below matter, but the settings matter more, and it is worth an hour with the phone in your hand before installing anything at all.
Start in the settings, not the store
- Turn on Live Caption It captions any audio playing on the phone, including videos with no subtitles and, on many phones, calls. Usually under Accessibility, or on the volume slider.
- Switch on flash notifications Camera flash, screen flash, or both, when a call or message arrives. Recent Android versions include this; older ones need one of the apps below.
- Set vibration to its strongest setting Ring vibration and notification vibration are separate settings on most phones, and both are often at a level designed not to annoy anybody.
- Check hearing aid compatibility Android supports hearing aids and cochlear processors over Bluetooth on many recent phones. The pairing lives under Accessibility rather than the usual Bluetooth screen.
- Turn on mono audio and adjust the balance If one ear is better than the other, mono audio stops half the sound disappearing, and the balance slider sends it where it is useful.
- Pair a watch if there is one A wrist that vibrates is the single most reliable alert there is, and it works when the phone is in a coat on the other side of the room.

Four different problems, four different tools
| What you want | What does it | What it will not do |
|---|---|---|
| Know the phone is ringing | Flash alerts, strong vibration, a watch | Help once you have answered |
| Read what somebody is saying | Live transcription apps | Be perfect in a noisy room |
| Hear better rather than read | Amplifier apps with headphones | Replace a fitted hearing aid |
| Follow video and calls | Captions, subtitle-capable players | Caption a live broadcast well |
| Know a sound happened at all | Sound notification features | Tell you which neighbour's alarm it was |
What to install
Live Transcribe, and the first thing to install. It captions speech in real time and separately alerts you to sounds like a doorbell, a smoke alarm or a knock at the door.
Turns wired or Bluetooth headphones into a directional amplifier that boosts speech and holds back background noise. Most useful in a restaurant or a meeting.
Android's accessibility suite, updated independently of the system, so an older phone gets current accessibility features without a system update.
Built for group conversation rather than one voice, and colour-codes who is speaking. The free tier is limited, so check what it currently allows before relying on it.
For the transcript afterwards rather than the words right now. A searchable record of a lecture or a meeting, which is a different job from live captioning.
Transcribes and searches recordings on the device itself. It is a Pixel app, so it is only an option on those phones.
A fast dictation pad for the times it is easier to speak your side and let the other person read it, rather than typing on a phone keyboard.
Runs a hearing test and shapes amplification to the result. It is a consumer app using ordinary headphones, not a medical device, and it does not replace an audiologist.
A simpler amplifier with fewer settings, for the case where the full test-and-profile approach is more than anybody wants to deal with.
Camera flash on a call or a message, for phones whose system settings do not offer it. Worth checking how hard it leans on the battery in normal use.
The alternative, with more control over which apps trigger a flash and when it stays quiet.
Its strong point here is waking somebody through a watch or a wearable rather than a sound, which is the part standard alarms get wrong.
Loads an external subtitle file and lets you set size, colour and position, which matters more than people expect on a phone screen.
The same job with no advertising, and it will shift subtitle timing when a downloaded subtitle file runs ahead of the video.
Video calls with live captions, which makes it the easiest call type to follow when the audio alone is not enough.
Its conversation mode is a rough captioner when nothing else is installed, and genuinely useful when the other person is also speaking another language.
Shows how loud a room actually is in decibels. Useful for settling why one restaurant is impossible and another is fine, and for choosing where to sit.
A monitor that vibrates the phone and shows sound levels visually rather than only playing audio back.
What live captioning is good and bad at
- One person, close, in a quiet room
- Clear speech in a common accent
- Video and podcasts played on the phone
- A phone call held near the speaker
- Several people talking over each other
- Background music or a busy café
- Names, places and technical vocabulary
- Heavy accents and very fast speech
Two practical points. First, transcription may run on the device or in the cloud depending on the app and the language, and that difference matters if the conversation is private, so check the app's own description rather than assuming. Second, accuracy varies enough that a captioned medical appointment or legal conversation should have a human involved as well. Captions are an enormous help; they are not a transcript of record.
Spend the first hour in Accessibility settings, then add live transcription and flashing alerts. A vibrating wrist covers what neither of those can.
Frequently asked questions
Can a phone replace a hearing aid?
No. Amplifier apps with headphones help in specific situations, particularly a noisy room, but they are not fitted to your hearing the way a prescribed device is and they should not be treated as a substitute for one.
Will Live Caption work on a phone call?
On many recent phones, yes, and on others it captions only media. It depends on the phone, the Android version and the region, so test it on the actual device rather than assuming either way.
Does any of this work without an internet connection?
Some of it. Several transcription features have on-device models for certain languages and work offline; others need a connection. Test each one in aeroplane mode so you know which is which before you need it.
What is the single most useful change?
A watch or band that vibrates, paired to the phone. It solves the missed-call problem completely, which no app on the phone itself can do when the phone is in another room.
