How to permanent track a lost phone or any network device

How to track a lost Android phone with Android Device Manager

If you have lost your phone don’t worry, it is often possible to get it back. With the free Android Device Manager tool you can locate your phone, seeing its position on a map so you can track it down

ADM also enables you to lock the device so that nobody will be able to see your data, and if you suspect it may have actually been stolen instead then you can remotely initiate a factory reset—wiping all your information and accounts so they are completely protected.

Android Device Manager is built-in on every new Android phone and tablet and it runs permanently in the background. So long as the device has an internet connection either through your SIM card or wi-fi, it is able to report the its whereabouts. Accessing the information that ADM is reporting is done via your Google account on any web browser—so even if you’re travelling when you lose it you still have a chance of tracking it down.

Activate Android Device Manager

ADM is rather hidden within Android. Go to Settings > Security and scroll down to Device administrators. Here you will see an option labelled Android Device Manager. Tick the box to activate the service.

That’s all there is to it. There’s nothing else to configure on the handset itself—the service will function as and when you need it.

Your phone’s position will be shown on a Google Map. It’s accurate to a few metres although does not update in real time so refresh the screen to see if it is moving.

If the phone is nearby—lost somewhere in your house, for example—click the Ringbutton. The phone will ring for five minutes at maximum volume (even if you’d got it set to silent). When you find the phone press the power button to stop it ringing.

If the device isn’t nearby but you think you may be able to recover it you can click the Lock button. This locks the device and replaces the existing lock screen. You can add a message asking the person who finds the device to contact you.

Alternatively, if your device has been stolen, or you don’t want to risk your data you can click the Erase button. This will completely wipe the phone by performing a factory reset.

If you’ve got more than one Android device you can install the Android Device Manager app on both of them and you’ll be able to track and manage one from the other.

If your phone is turned off

Your device needs a live data connection to be able to be tracked. However some commands, such as the Erase command, will be sent and executed the next time the device connects to the network. Obviously if the person in possession of the phone factory resets it there’s nothing you can do, although at least your data will not be compromised if this happens.

Track your phone

You can locate and manage your phone through any web browser. Go to www.google.com/android/devicemanagerand login to your Google account.

The device manager service will now launch and attempt to make contact with your phone. So long as the phone is switched on and has an internet connection it should be found within just a few seconds.

how to create(boot from) multiple operating system in 0ne pc(computer)

Computers normally have a single operating system installed on them, but you can dual-boot multiple operating systems. You can have two (or more) versions of Windows installed side-by-side on the same PC and choose between them at boot time.

Typically, you should install the newer operating system last. For example, if you want to dual-boot Windows 7 and 10, install Windows 7 and then install Windows 10 second. However, this may not always be necessary — installing Windows 7 after Windows 8 or 8.1 seems to work.

The Basics

The process for creating a dual-boot system is similar no matter what operating system you’re dual-booting with. Here’s what you’ll need to do:

• Install the First Version of Windows: If you already have a single Windows system installed on your computer, that’s fine. If not, install Windows normally. You may want to use custom partitioning settings and leave free space available on your hard drive for the second version of Windows.
• Make Room For the Second Version of Windows: You’ll need available hard drive space for the next version of Windows. If you have Windows installed, you can resize the partition. You could also insert a second hard drive into your computer (if it’s a desktop computer) and install the second version of Windows to that hard drive.
• Install the Second Version of Windows: Next, you’ll install the second version of Windows. Ensure you choose the “Custom Install” option, not the “Upgrade” option. Install it alongside the previous version of Windows, in a different partition on the same disk or on a different physical disk.

You’ll then be able to choose which copy of Windows you want to boot at boot time, and you can access the files from each version of Windows on the other one.

Install the First Version of Windows, If It’s Not Already Installed

Install the first version of Windows on your PC, assuming it’s not already installed. If your computer already has Windows installed on it, that’s fine. If you’re installing Windows fresh, you’ll want to choose the “Custom install” option when going through the installation wizard and create a smaller partition for Windows. Leave enough space for the other version of Windows. This means you won’t have to resize partitions later.

Shrink Your Windows Partition

You’ll now need to shrink your existing Windows partition to make room for the second copy of Windows. If you already have enough free space or you’re installing the second copy of Windows to a different hard disk entirely and it has available space, you can skip this.

Basically, this involves booting the existing Windows system on your computer and opening the Disk Management tool. (Do this by pressing Windows Key + R, typing diskmgmt.msc into the Run dialog, and pressing Enter.) Right-click the Windows partition and select the “Shrink Volume” option. Shrink it to make enough space for the other Windows system.

RELATED: How to Set Up BitLocker Encryption on Windows

If you’re using BitLocker encryption on your Windows system, you’ll first need to open the BitLocker Control Panel and click the “Suspend Protection” link next to the partition you want to resize. This will disable BitLocker encrpytion until you next reboot, and you’ll be able to resize the partition. Otherwise, you won’t be able to resize the partition.

Install the Second Version of Windows

RELATED: Where to Download Windows 10, 8.1, and 7 ISOs Legally

Next, insert the installation media for the second version of Windows you want to install and reboot your computer. Boot it and go through the installer normally. When you see the “Upgrade” or “Custom install” option, be sure to select “Custom” — if you select Upgrade, the second version of Windows will install over top of your first version of Windows.

Select the “unallocated space” and create a new partition on it. Tell Windows to install itself to this new partition.  Just be sure not to select the partition containing the version of Windows currently installed on your system, as two versions of Windows can’t be installed on the same partition.

Windows will install normally, but it’ll install alongside the current version of Windows on your PC. Each version of Windows will be on a separate partition.

Choosing Your OS and Modifying Boot Settings

When the installation is finished, you’ll see a boot menu every time you boot your computer. Use this menu to select the version of Windows you want to boot.

Depending on which versions of Windows you’re using, the screen will look different. On Windows 8 and newer versions of Windows, it’s a blue screen with tiles with the title “Choose an operating system.” On Windows 7, it’s a black screen with a list of operating systems and the title “Windows Boot Manager.”

Either way, you can customize the boot menu’s settings from within Windows itself. Open the Control Panel, click the System and Security option, click the System icon, and click Advanced System Settings at the left side of the window. Select the Advanced tab and click the Settings button under Startup & Recovery. You can choose the default operating system that boots automatically and select how long you have until it boots.

---

If you want more operating systems installed, just install the additional operating systems on their own separate partitions.

How to find a lost phone, whether it’s Android, iPhone, or any other kind

So you’ve lost your phone. We’ve all been there. It was just in your pocket a minute ago — and now it’s gone, lost to the phone fairies, forgotten between the seats of your couch, or misplaced somewhere during your busy day. Maybe it’s just in your other coat, or maybe it’s already in the hands of someone who found it on the sidewalk. Either way, all you want to do is get it back.

Thankfully, there are plenty of ways to get a hold of your missing phone. If it’s a smartphone (or even a tablet) running iOS, Android, or even Windows Phone, chances are good it already has the software needed to hunt it down — or there’s an app you can install to track your phone. Here’s our guide on how to find a lost phone or a similar device.

Have you ever wondered what happens to a smartphone after it’s stolen? Read how this filmmaker spied on a thief to find out.

Smartphones
If your lost phone happens to be a smartphone, all three of the major smartphone platform providers (Apple, Google, and Microsoft) include phone retrieval technology in their smartphones. Usually, the way these apps work is through the account associated with your device. For Android devices this is your Google account, for iPhones, this is your iCloud account, and for Windows Phones this is your Microsoft account. All three allow you to remotely lock and wipe your phone, make it ring, and set up special messages to alert whoever finds it.

Of course, these features are only as good as your phone’s battery. If your smartphone dies, it’s about as easy to find as your wallet or anything else you might misplace.

We also recommend caution when communicating with anyone who has found your smartphone. Be careful to avoid giving away any personal information, such as your home address, until you know you’re dealing with someone you can trust. Stick with sending phone numbers or email addresses to communicate how the good Samaritan can return your phone. Here’s how each of the three operating systems work.

How to find a lost Android phone
Android not only offers Google’s proprietary service for finding and managing your device remotely but also a number of third-party apps designed for finding your smartphone. The easiest to use is Find My Device, which is built directly into your Android smartphone through Google Play Services — it can also be used in a browser or downloaded from the Google Play Store. Most devices running Android 2.3 or later should be able to use this feature.

Using the feature is as easy as searching  “Where is my phone” in Google, which will prompt the service to start looking for your smartphone. We’ve previously written about Find My Device and its ability to call you, set up a new password, and make your phone ring from afar, along with the variety of other functions it uses for notification purposes. While you can configure Find My Device ahead of time, the service should be available in the event you lose or misplace your phone. It will use Wi-Fi or GPS to help you hunt down your device.

To verify your Android smartphone has the Find My Device feature turned on, go to Settings > Google (or Google services) > Security and make sure Remotely locate this device is turned on in the Find My Device section.

If you can’t find your smartphone, you can always wipe it to prevent sensitive information from getting into the wrong hands. Your device will need an internet connection, however, and enough juice to communicate with you. In Android 5.0 Lollipop, Google also introduced Factory Reset Protection (FRP). It’s designed to prevent would-be thieves from being able to steal your phone, wipe it, and then use it or sell it. If you factory reset a phone with FRP enabled and try to set it up as a new device, you’ll be prompted to enter the username and password for the last Google account that was registered on the device, and if you can’t, the phone will remain locked.

There are also third-party apps that you can install to help you find your phone. Cerberus Anti-theft is a great app that offers remote access and control, allowing you to obtain more information regarding the whereabouts of your phone. It provides a number of additional features, such as more granular control on how you track your device, screenshots of what your device is doing, photos from the camera to possibly catch the would-be thief, and other, more detailed notifications that Find My Device doesn’t offer. If your device is rooted, there are even more features available to prevent someone from resetting or turning off your device until you can recover it.

Another option for select Samsung smartphones is the Find My Mobile service. It can be used to locate a missing phone, lock it down, or wipe it completely. You’ll need a Samsung account, though, and the Remote Controls options enabled on your phone. To check and see if Find My Mobile is available for your smartphone, go to Settings > Lock screen & Security. If you see Find My Mobile in the menu, you can use the service; enable the Remote Controls options via Settings > Security > Find My Mobile > Remote controls.
