One of the most common Google searches is “find my phone” and with these 
Android apps, you will be able to find your phone very quickly. Please note that
the only good
 way to find your smartphone is if you have something installed already.
Make sure you have a plan in place in case something goes wrong. However,
 here are five best Android apps to find your phone:
 Android Device Manager
Android Device Manager is a functionality that is built into every Google Android
 device and can be turned on by simply flipping a setting. You can learn more on
 how to do that by clicking here.
Once enabled, you can use Android Device Manager on your Android device or computer to find your device. From there, you can get it back, wipe the device, sound an alarm so you can find it, and even reset your lock screen PIN. It is an essential tool that is built right into Android and you should definitely take advantage of it.
Family Locator
Family Locator by Life360 does exactly what the app name says it does. It allows you to create a collective with your family and
 friends and then you can keep track of where they are through their smartphone (s).
This is also very useful in case one of your friends or family loses a smartphone. 
You will be able to use the app to find it and help them get it back. Since this is 
more of an app 
that finds people rather than smartphones, it doesn’t have as many stolen phone features
 but it’s still better than nothing and it’s great for parents!
 Cerberus
Cerberus has long been the name people think of when it comes to anti-theft applications. It has a diverse set of features that include locking and resetting your phone, sounding
 alarms, displaying messages on screen for thieves to read, and it even has access to the 
front-facing camera so you can take a picture of the thief.
You can also hide Cerberus from the app drawer so people don’t suspect that
 it’s there, remote shell into your device, and record audio from the mic. It’s powerful
 and 
it’s an app everyone should think of getting.
Prey Anti-Theft
Prey is an app that has been around for a while that many people trust. Its entire
 purpose is to help you find your phone if it goes missing but is more lightweight than
 something like Cerberus.
It has the basic features like finding your phone, locking your device, and setting
 off an alarm. You will also be able to take pictures to see where your device may be and 
gather network information to see where your device has been. It seems to work for most 
people and that is what really matters.
 Where’s My Droid
Where’s My Droid has been around for a long time and although it looks simple, this
 little app has a lot of power. It has the basic features like finding your phone, locking
 it up, and
 more.
The unique features include the ability to send “GPS Flare” when the battery is low 
so you’ll get the last location no matter what. You can also control who can find your
 phone 
by using text messages.
There is a free version that covers the very basics with a pro version that unlocks 
features like remote wiping, keeping the app from being uninstalled, hiding the app 
icon, and the ability to use a landline when activating the app.
