Apps from the web
You can get apps from online app stores using your browser.
Tip: Choose your apps and updates carefully, as some may 
impact your phone’s performance—see “Choose carefully” 
on page 15.
Note: When installing an app, make sure you read the alerts 
that tell you what information the app will access. If you don’t 
want the app to have access to this information, cancel the 
installation.
To let your phone install apps that are not on Google Play, tap 
Apps  >

To download files from your browser, see “Downloads” on 
page 41.
Choose carefully
Apps are great. There's something for everyone. Play, 
communicate, work, or have fun. But remember, choose your 
apps carefully. Here are a few tips:
• To help prevent spyware, phishing, or viruses from affecting 
your phone or privacy, use apps from trusted sites, like 
Google Play Store.
• In Google Play Store, check the app’s ratings and comments 
before installing.
• If you doubt the safety of an app, don’t install it.
• Like all apps, downloaded apps will use up memory, data, 
battery, and processing power—some more than others. 
For example, a simple battery level widget will use less than 
a streaming music player app. After installing an app, if 
you’re not happy with how much memory, data, battery or 
processing power it’s using, uninstall it. You can always 
install it again later.
• Just like web browsing, you may want to monitor children’s 
access to apps to help prevent exposure to inappropriate 
content.
• Certain apps may not provide completely accurate 
information. Take care, especially when it comes to personal 
health.
