How to find your lost Android phone

Source: Android Central

Worried about misplacing your Android phone or (worse yet) having it stolen? Ease your fears and set up a tracking system before your worst case scenario strikes. You’ll get the best results if your phone is connected to a Wi-Fi signal but GPS and mobile networks will still manage to pinpoint a fairly accurate location. You must also have a Google account for virtually all of the tracking services available, whether they are built-in or downloaded.

How to locate your phone using Google

Most Android phones now come with Find My Device built right in. This service automatically tracks your phone’s location, so if it ever goes missing you can hop on your laptop or a friend’s phone and find its last known location, ring your phone if it’s nearby, or lock and/or erase your phone if you fear it has been stolen.

The most important thing you can do is make sure your phone is set up to be found before it goes missing. Otherwise, you’re basically on your own. An important point to note here is that you should always have your phone’s IMEI and serial numbers handy. You can easily find your phone’s IMEI number by dialing *#06# from your phone’s dialer.

The IMEI number is a unique identifier, and is what your phone uses to register to cell towers. You can get your phone’s serial number from the settings. Go to Settings -> About phone and you should see the serial number. Having this information is useful particularly if your phone is stolen and you need to register a complaint with the police.

Let’s get back to Google’s built-in utility. You’ll be signed into Find My Device as soon as you set up your phone, but there are a few times when things don’t work the way they’re meant to. In such a scenario, all you need to do is download the Find My Device app from the Play Store and sign in with your Google account. Once you do so, it will stay active on your device, and you’ll be able to use it to locate your phone remotely.

Should you happen to lose your phone, you can locate its whereabouts by logging into your Google account from any computer or even from another phone. Just launch any web browser, navigate to android.com/find, and enter your email address and password if you’re not signed in to your Google account on that device. If you have 2-step verification set up on your Google account (and you most certainly should), you’ll need to complete that as well.

With Find My Device open, you have three options to choose from:

• You can play a sound so that it makes noise (even if you had it on silent). This feature is helpful if the map indicates that the phone is within earshot and you simply can’t see it.
• You can secure your device so that the finder can’t access your home screen. This feature is most helpful if your phone wasn’t previously secured with a passcode or a fingerprint sensor.
• You can erase your phone. This is the best option if you know for certain that you aren’t likely to retrieve your phone.

If you are trying to locate your phone with Find My Device and it doesn’t seem to be working, the most likely cause is that your phone is not currently connected to Wi-Fi or an available network. In this case, it’s important to keep trying; the moment your phone does make that connection, it will appear on the map. Here’s a more detailed take on how Find My Device works.

If you want to download a tracking app for fear of a missing phone crisis, there are a number of options to choose from, and we’re highlighting some choice picks for you further below. But first, let’s see how you can find your phone inside your house via Google Home.

How to locate your phone in your house using a smart speaker

Source: Android Central

It’s embarrassingly easy to lose your phone by putting it down somewhere in your house and forgetting where you left it. This can be frustrating if it’s time to leave for work or some other appointment and you’re frantically scrambling around your home looking for it.

If you own a Google Assistant speaker, you can use Assistant to help find your phone. Your Android phone must be logged into the same Google account as your smart speaker, you must have linked your Google account and voice via the Home app, and your phone must be turned on and connected to the internet either via mobile data or Wi-Fi. You will also need to have Find My Device turned on, which you should absolutely activate for any Android phone you’re using.

As long as your phone is still on and connected to the Internet, all you need to do is say, «Ok Google, find my phone,» and Google will confirm which device you want to find and then turn the ringer on — even if you have your phone set to silent. With Google Home’s multi-user support, everyone in your home can use Google Home to find their phones if they’re lost as long as they’ve linked their Google Accounts using Voice Match.

How to locate your phone with third-party apps

While Google’s built-in option is definitely your best bet, there are some third-party options you might want to consider. We’ve broken down the best third-party apps for finding your phone below.

The ideal choice : Life360 Family Locator

The Family Locator app by Life360 is essentially a GPS tracker for phones but is especially useful for families with multiple phones in use. Your family members become a «Circle», the app’s name for a closed group of people who consent to have their phones tracked in real time. Your family members will appear on live maps within the app as little icons so that you can see where everyone is at any given moment.

Also great : Prey Anti Theft

The Prey Anti Theft app is impressive in that three different devices can be protected through one download. You’ll have the ability to sound an alarm from your missing phone, take screenshots if it’s in use, and lock down the device the moment you realize it’s missing. The best part is that it’s absolutely free to use.

Control your phone remotely : Lost Android

Lost Android will allow you to have remote access to your missing phone via their website. Here, you’ll be able to erase sensitive information if you fear that your phone may never be returned, or send messages to your phone in the hopes of someone finding and returning it.

A safe bet : Where’s My Droid

The basic features of the Where’s My Droid app allow you to ring your phone if you misplace it, locate it via GPS on Google Maps, and use a passcode to prevent unauthorized changes to apps on your Android phone. Stealth Mode also prevents anyone who finds your phone from seeing your incoming text messages; instead, they’ll see a customizable attention word that alerts them of the phone’s lost or stolen status.

Google is your best solution for finding your phone

Google’s phone location tools are your best bet — as long as you’ve gone through the process of setting things up ahead of time. Really, this should be something you set up on any device you care about or that will have sensitive data stored on it, especially with how easy Google has made it to locate your device should you lose it.

Of course, one of the benefits of Android is having the freedom to customize your experience as you see fit. If for whatever reason Google’s offering just doesn’t cut it for you, you should consider the third-party options we’ve highlighted above, as they include some clever features that might give you some added peace of mind if your device goes missing.

If all else fails, block your phone’s IMEI

If your phone is stolen or found and it’s then factory reset, you will not be able to rely on any apps or services to find it; a factory reset will wipe out any of the original data, accounts, or passwords that are needed to remotely find your Android phone.

Then you’ll have to use the nuclear option of blocking it with its IMEI number. Doing so will at least make sure that no one else will be able to register the phone on cell networks. You should contact the police as soon as possible once your phone goes missing, and furnish its IMEI number. You’ll also need to do the same with your carrier or service provider, and it will be added to a blacklist.

There are services like Stolen Phone Checker in the U.S. and Device Check in Canada that let you key in an IMEI and see if that particular device has been reported as lost or stolen. There’s also IMEI24, which has a global database.

As always, exercise caution when retrieving a lost or stolen phone. If you have any worries about your phone being lost or stolen, it’s best to set up and test your preferred tracking system as soon as you buy it and contact the police. It can be a bit of extra front-end work to register some apps, but it will be more work trying to locate a missing phone if no safety nets are in place at all.

What Is a Cellphone? Cellphones, Coverage, and Networks

And why are cellphones called cellphones?

A cellphone is any portable telephone that uses cellular network technology to make and receive calls. The name comes from the cell-like structure of these networks. There is some confusion about cellphones being classified differently from smartphones. Still technically, every mobile phone, from the latest Android handset to the simplest feature phone, is a cellphone. It’s all about the technology used to transmit your calls, rather than what the handset itself can or cannot do. As long as a phone can send a signal to a cellular network, it’s a cellphone.

Getting the Terms Right

The term «cellphone» is interchangeable with the terms «cellular phone» and «mobile phone.» They all mean the same thing. The term «smartphone» means a cellphone that offers advanced features beyond calls, SMS messages, and basic organizer software. When people talk about mobile phones, «cellphone» is typically used to describe a simple feature phone. In contrast, «smartphone» describes advanced touch-screen phones.

History of Cellphones

Motorola developed the first commercially available cellphone between 1973 and 1983 and went on sale in the U.S. early in 1984. This giant 28-ounce cellphone, called the DynaTAC 8000x, cost $3,995 and needed to be charged after just 30 minutes of use. The DynaTAC 8000x is almost unrecognizable as a cellphone when compared to the devices we use today.

It’s estimated that more than 6 billion cellphones (including smartphones) were in use at the end of 2020.

Why Are They Called Smartphones?

Cellular Networks

A cellular network, which gives cellphones their name, is comprised of cellular masts or towers distributed across the country in a grid-like pattern. Each mast covers a relatively small region of the grid, usually around 10 square miles, called a cell. Large mobile phone carriers, such as AT&T, Verizon, and T-Mobile, erect and use their own cellular towers and control the level of cellular coverage they can provide. Cellular providers don’t own all the land their towers are on; instead, large companies often lease the land from the owners. In turn, the large carriers often allow smaller regional carriers to use their towers for a fee.

When you make a call on a cellphone, the signal travels through the air to the nearest mast or tower. Then it’s relayed to a switching network and finally on to the handset of the person you are calling via the mast closest to them. Suppose you’re making a call while traveling in a moving vehicle, for example. In that case, you may quickly move from the range of one cell tower to the range of another. No two adjoining cells use the same frequency to avoid interference, but the transition between cellular mast areas is usually seamless.

Cellular Coverage

In some countries, cellular coverage is available almost anywhere if you’re with one of the large national carriers—in theory. As you might expect, cellular coverage in highly populated areas is usually better than coverage in rural or sparsely populated areas. If you’re thinking of changing your carrier, research its coverage in your local area first.

Cellular masts in cities are often close together, sometimes only a few hundred feet apart, because buildings and other structures can interfere with the signal. In open areas, the distance between masts may be several miles because there are no buildings or other structures to disrupt the radio waves. If the cellular signal is weak (rather than nonexistent), consumers can buy a cellular repeater or network extender, both of which can amplify and boost a weak signal.

Unlocked phones work with any cellular provider, unlike locked phones that you must use with a particular carrier. While unlocked cellphones come with the freedom to choose your service provider, you can only select carriers that use compatible mobile phone technologies such as GSM or CDMA.

To block a number on your Android device, select the number from the Phone app and look for a Block or Block/report spam option. If your Android phone allows it, you can also block all unknown numbers from Phone > Settings > Blocked numbers > Unknown. On iOS, select a number in the Phone app and choose Block this caller or silence all unknown numbers on an iPhone from Settings > Phone > Silence Unknown Callers.

At present mobile phones have become ingrained in our everyday lives and the majority of people can hardly imagine themselves without cell phones. Is it just a tribute to fashion or a necessity of a modern person?

It isn’t a secret that today many people feel quite helpless if they have left their mobile phones at home. First of all cell phones give us an opportunity to keep in touch with people in any place and in any time (it’s especially important for businesspeople). Besides, modern mobile phones are multi-function: they provide access to the Internet, have various games, cameras, memory sticks, etc.

Nevertheless we can’t deny that mobile phones provoke a range of problems. People have started to see each other less frequently. Mobile communication requires quite a lot of money and people have to control the amount of money on their accounts constantly otherwise at the most inappropriate moment they won’t be able to phone the people they need. But the greatest disadvantage of cell phones is certainly their harmful influence on people’s health.

In my opinion at the present time mobile phones are an integral part of life of any person and we can’t stop it. I personally need it everyday for my work and to keep in touch with my friends and relatives, though I’m aware of its deleterious influence on my health. But I try to avoid idle talks on the phone to reduce the influence of harmful radio waves. I try to find the happy mean .

Mobile (or cell) phones are becoming an extremely popular electronic device and sometimes they are even replacing house phones. They are also becoming more technologically advanced: most can take and send pictures and videos and connect to the Internet. Mobile phones can be used to look up weather or answers to questions on search engines. Many children are becoming mobile phone owners. But we should be aware of both the positive and negative aspects of mobiles.
Let us start with the advantages of buying a mobile for a child. First of all, many mobile phones allow access to the Internet, which can help a child to find answers to questions very quickly and easily. This can help with studies and other simple questions like daily weather or finding directions to go to some place.
Secondly, some mobile phones have tracking devices. So parents can track where their child is at any moment, to know that he\she is safe.
Thirdly, mobile phones can be a learning tool for children. There are many applications that can help to learn new words or simply train your memory.
And last but not least, mobile phones allow parents and children to stay in touch. Mobile phones can be important in emergency situations or when a parent needs to quickly get in touch with a child or vice versa.
At the same time there are certain disadvantages in mobile phones usage. First and foremost is cheating. Students can text answers under their desks during tests. Some students try to find answers to test questions on the Internet using their phones.
Moreover, mobile phones can be very distracting from important events in a student’s life such as studying, doing homework, or even crossing the street.
Besides, children can receive abusive messages from other students or from strangers.
And finally, mobile phones are not cheap.
All in all, mobile phones have already become an important part of our daily life and communication. We just have to use them wisely.

A. Mobile phones use ‘radio waves’ to send signals. Since the 1920s, scientists have known that radio waves can cause the heating of the skin and influence the nervous system. But mobile phones don’t produce many radio waves. Still children should be especially careful about mobile phone use because their nervous system may be hurt. Children should only use mobiles for short calls.

B. It is known that the strength of radio wave radiation decreases with distance. It suggests that hands-free sets may be effective in avoiding all the dangers of mobile phones. But another study described an increase in radiation that reached the user of a hands-free set. It says that the cable of the hands-free set acted as an antenna, directing more radio waves into the user’s ear.

C. Train passengers will soon be able to buy tickets on their mobile phone. Chiltern Railways plans to sell tickets through mobile phones. The new technology sends a code to a mobile phone in a text message, which passengers can then scan at the station ticket barrier. It’s hoped the method will make buying tickets easier for passengers and help fight against queues at stations.

D. Many parents now use mobiles to control their children’s behaviour. It gives parents peace of mind and makes young people feel protected. Parents say that young people are safer with mobiles than without them. But, while parents said they liked to call their children on the mobile to actually hear their voice, young people liked to send text messages to parents.

E. A research showed that those young people who have a mobile feel more independent and often use it to plan meetings both relatives and peers. In particular, young people often use mobiles to ask their parents if they can come home later. The study showed that girls more often text parents to let them know they were safe than boys. They also use text messaging for socializing purposes.

F. It is not only parents who want to connect with young people through mobile technologies. Nowadays politicians and different organizations look for ways to use text messaging as a channel for communication with the young. In late 2004, the UK government offered people the opportunity to ‘text Tony’. People were invited to send a text question to the prime minister to be answered as part of a ‘mobile chat’.

G. The popularity of text messages led to the development of a special system of words or ‘chat speak’. For example, acronyms, that are words made from the first letters of other words, are often used both in online chatrooms and text messages sent to your mobile phone. This ‘chat speak’ is very popular with children who are fast at texting. Parents might be interested to know that ‘PAW’ means ‘parents are watching’!

I think every person today has a mobile phone, even little children do. For many people it is a necessary thing for everyday life. Moreover their whole life is in their mobile phone.

As for me I can’t imagine my life without a telephone now. Lately mobile phones have become not only a thing which is used to call people but a lot more. Mobiles have taken the place of computers and laptops. A person can check emails, search for information thanks to the internet connection on mobile phones. We can also listen to music, watch films, videos, read books and chat to our friends with the help of mobiles. It also helps us to stay in touch with people who are far away and with whom we can’t meet for some reasons. It seems nothing can be better than having everything in just one little gadget.

In fact not everything is so wonderful as it seems at the first sight. Just look at people around — they are obviously addicted to their mobiles like to drugs. Every second you see a person staring at his telephone screen. Children are playing games and applications in their mobiles instead of playing football or walking with friends. People forget what it is like to communicate face to face, they only chat to people online. Moreover using mobile phones very often is dangerous because of radiation we get.

I think mobile phones are very useful in people’s life, but we need to find a balance between mobile and face to face communication.
