Virtual assistants usually hog the spotlight
when it comes to talk of artificial intelligence software on smartphones and
tablets. But Apple’s Siri,
Google Assistant, Samsung’s Bixby and company aren’t
the only tools using machine learning to make life easier — other common
programs use the technology, too.

Here is a quick tour through some common
AI-driven apps and how you can manage them.
Device Security
When you set up a new device, you are usually
invited to “enroll” in its facial recognition security program, which captures
your image and analyzes it so the program will recognize you in different looks
and lighting situations. Later, when you want to unlock the device or use apps
like digital payment systems, the camera confirms that your face matches the
stored data so you can proceed.
If you decide to use the feature, check your
device maker’s privacy policy to see where that data is stored. For example,
Apple states that “Face ID data does not leave your device,” and Google says it
stores face data on the security chips on its Pixel phones. If you sign up and
then have second thoughts, you can always go into your phone’s Face ID or Face
Unlock settings, delete or reset the data, turn off the feature and stick with
a passcode.
Photo Apps
Apple’s Photos and Google Photos use
artificial intelligence in several ways, including facial recognition, scene
detection and image analysis to automatically sort pictures of people, places
and things into albums. This sorting saves you from manually tagging everything
and makes it easier to find specific photos in a keyword search. (Apple and
Google have technical papers about facial recognition on their sites.)
Apple says all the facial recognition and
scene detection in its Photos app is performed locally on the device. You can
also edit the People album.
Google Photos retains the face-grouping data
in your Google Account. In the settings, you can turn off the face groupings
and edit the descriptive tags.
The default camera apps use machine learning
in the image processing to produce sharper photos. Apple’s Scene Detection and
Photographic Styles features enhance the image based on what is in the picture,
and the blur- and noise-reduction editing tools in Google Photos use AI to
improve images.
Writing Aids
If you have ever been typing along on your
phone’s keyboard and noticed suggested words for what you might type next, that
is machine learning in action. Apple’s iOS software includes a predictive text
function that bases its suggestions on your past conversations, Safari browser
searches and other sources.
Google’s Gboard keyboard for Android and iOS
can offer word suggestions, and Google has a Smart Compose tool for Gmail and
other text-entry apps that draws on personal information collected in your
Google Account to tailor its word predictions. Samsung has its own predictive
text software for its Galaxy devices.
The suggestions may save you time, and Apple
and Google both state that the customized predictions based on your personal
information remain private. Still, if you would like fewer algorithms in your
business, turn it off. On an iPhone (or iPad), you can turn off Predictive Text
in the Keyboard settings.
For some apps like Gmail, you can turn off the
predictive text and the use of your personal data for suggestions in the
overall settings for your Google Account. On certain Android phones, you can
also control permissions or delete data collected by the Android System
Intelligence software in the Privacy and Apps settings.
Augmented Reality Apps
Google Lens (for Android and iOS) and Apple’s
Live Text feature use artificial intelligence to analyze the text in images for
automatic translation and can perform other helpful tasks like Apple’s “visual
look up.” Google Lens can identify plants, animals and products seen through
the phone’s camera, and these searches are saved. You can delete the
information or turn off the data-gathering in the Web & App Activity
settings in your Google Account.
In iOS 15, you can turn off Live Text by
opening the Settings app, tapping General and then Language & Region and
turning off the button for Live Text. Later this year, Live Text is getting an
upgrade in iOS 16, in which Apple stresses the role of “on-device intelligence”
in doing the work.
Virtual Assistants
These AI-in-action tools are most useful when
they have access to personal information like your address and contacts. If you
have concerns, read your phone maker’s privacy policy: Apple, Google and
Samsung all have documents posted in their sites. The nonprofit site Common
Sense Media has posted independent privacy evaluations for Siri, Google
Assistant and Bixby.
Setting up the software is straightforward
because the assistant guides you, but check out the app’s own settings to
customize it. And don’t forget the general privacy controls built into your
phone’s operating system.
