HTC frequently asked questions

HTC One: Ten frequently asked questions

We're getting ever closer to the public release of the HTC One, with the all-new Sense 5, and we're putting this guy through its paces. There's quite a lot to go over, and we're getting a lot of the same questions from many of you folks on Twitter, Google+ and in our HTC One forums.

Our full review is coming in due time, of course. For now, let's tackle a few burning questions regarding the HTC One and Sense 5. (Chances are you'll see another installment at some point, so don't fret if we haven't answered your question just yet.)

Here we go!
1. Do I have to use BlinkFeed? Can I uninstall it?

You absolutely do not have to use it if you don't want to. Just don't add any feeds to it, and it won't do anything. You might be able to hack it out of there, but we wouldn't bother. Just thumb over to the home screen and pretend that BlinkFeed never happened.

(Though we'd recommend giving it a shot. It's not bad.)
2. Wait - there's only one home screen? Can I add more?

Sure! By default there's only one. (Most people don't use more than that anyway.) But you can add as many as five home screen panels. Get to the "Customize home screen" section -- either from the "Personalize" section of the settings or by long-pressing a blank area on a home screen -- and then hit the "add panel" button.

You can then choose which home screen panel to set as the default when you hit the home button, or you can remove unwanted panels.
3. That app drawer seems a little funny. What's up with it?

First off, you're probably not used to seeing a clock and weather widget stuck to the top of the app drawer. But there it is. Start thumbing down and it'll disappear. The next odd thing is that apps are in a large, 3-by-4 configuration. (It'll look like 3-by-3 until you scroll down and get the clock widget to disappear.)

Also: Folders! Just below the clock widget is a line of icons. On the far left is the app drawer view -- you have "Custom," "Alphabetical" or "Most recent." When in custom view, you can drop apps on one another to create folders. If something obvious appears to be missing, change to alphabetical view and find it that way. Also note that if an app is docked at the bottom of the screen, it won't appear in the app drawer.

This all takes a little getting used to.
4. What does the HTC button on the bottom of the phone do?

Not a damn thing, because it's just a logo. Not a button.
5. So how do I get to the list of recent apps? (aka multitasking)

Double-tap the home button and you'll get a 3-by-3 grid of apps that are open. To close an app, just flick it upward with your finger.
6. And what about Google Now?

Hold down the home button on the HTC One to get to Google Now.
7. I miss that iconic HTC clock widget. Can I get it back?

Yep! It's available as a home screen widget. It looks like you have to have the new, sleek widget everywhere else, though.
8. Is there a notification light?

Sure is. It's hidden in the bottom row, on the third hole from the left, in the top speaker.
9. Can I customize the lock screen?

Just like in previous versions of Sense, you can choose whether to have a wallpaper displayed, a "productivity" scheme with notifications and calendar reminders, a photo album view or music player, or you can opt to go with no lock screen at all.

The application shortcuts are slaved to whatever apps you have docked to the bottom of the screens.
10. Are the speakers that good?

For a smartphone, yeah. They're about as good as anything we've used. You'll need to have Beats Audio turned on (and it is by default) to get the full effect. It's not that it'll replace a proper external speaker, but neither will you be embarrassed to play audio out of your phone.

IMEI Number:How To Track and Block Lost or Stolen Mobile Phone

If you have lost your mobile phone or if its stolen, then you can recover it or at least block it if you know the IMEI number of the phone.

The procedure to get back the stolen mobile phone will take some time so you must be patient. First you need to go to the police station in your area and file a FIR that your mobile phone is stolen.

Then take the copy of this FIR and the IMEI number of your phone and contact the service provider of your phone. They will then help you track the mobile phone location.

They will also block the mobile phone, making it useless until it is found. Once you find it, you can request your service provider to white-list it again.

This procedure will work even if the SIM card of the phone is changed because all service providers use the same blacklist database.

How this works? You probably already know that each mobile phone has a unique IMEI number. Whenever a mobile phone is switched on, this IMEI number is sent to Equipment Identity Register database. This database categorizes each phone in one of three categories: while listed, grey listed and black listed.

Your mobile service provider can block any mobile phone by putting its IMEI number in the black list. Once blacklisted, a mobile phone is useless as it cannot be used at all.

Your operator can also track the exact location of the mobile phone using its IMEI number using the Global Positioning System, thus helping you find the lost or stolen mobile phone. However, since a lot of phones get stolen these days, mobile operators will track a phone from its IMEI number only in the case of some special situation.

Note that when you contact your mobile service provider to block the mobile phone with its IMEI number, don’t forget to ask them to block your SIM also.

Also note that there are some specific apps that help you track lost or stolen mobile phones. For example, check the anti theft alarm for Windows phone. There are similar apps available for iPhone and Android phone as well and I will post reviews of these apps soon. Please post your comments below if you have any questions regarding tracking of lost or stolen mobile phones.

Find your lost phone or tablet with Android Device Manager

I carry both my smartphone and my tablet with me on a daily basis. I can’t imagine what I’d do if one of those devices went missing, what with all the sensitive data contained on them—not to mention my library of precious photos and e-books.

Google introduced the Android Device Manager (ADM) last year to help users locate lost devices, and quell security fears. Not only will ADM show you the location of a wayward device, it will also let you erase the data on the device if you suspect the hardware has been stolen.

ADM is extremely easy to set up, so you have no excuse not to use it.

Getting started

The Android Device Manager will keep track of any phone or tablet you’ve linked to your Google account. It’s compatible with any device running Android 2.2 or later, and it works even if you don’t have location history turned on.

When you first get your phone, head over to the Android Device Manager page to ensure that Lock and Erase are enabled. Google will send over a test message to your device to ensure that it works. Tap “Activate” to enable the remote wiping features.

Find your device

In the future, if and when your phone does go missing, just head to the ADM site. From here, you can select any of the Android devices you have linked to your Google account.

If you think the device might be buried under a pile of couch cushions, select Ring and the device will blare its ringtone for about five minutes. When you find it, press the power button to stop it.
If you think you left your hardware in a taxi cab on the way home from last night’s escapades, you’ll want to lock it up to keep prying eyes from accessing your precious data. Select Lock and ADM will ask you to create a new lock screen password. There will also be an option to write a Recovery message that will appear over your lock screen. This is your opportunity to type a message to the person who may have found your phone.

If you think your phone might really be in the wrong hands, or that it’s long gone and you'll never see it again, you can erase all of its data with Erase.



Someone terrible ran off with your Nexus 7, and, frankly, that’s pretty awful. Before you do anything, contact law enforcement and file a report. Phone theft is an epidemic, especially in urban areas.

If you’re fortunate enough to have a second Android device in your possession, download the Android Device Manager app from Google Play to get access to all the same features available online. If you’re bored, waiting in a doctor’s office or something, you can also use the app to individually rename each of your devices.

Keep in mind that ADM won’t work with devices that are offline or powered off, so if a thief puts your device in Airplane Mode or the battery dies out, you’re out of luck.

How to Find Stolen Android Phone’sby using IMEI number

All the mobile phones have an International Mobile Station Equipment Identity (IMEI) number which is unique for each single device. No other mobile phone in the world would share the IMEI number with anyone else. The IMEI number helps detect the current location and also the region of the smartphone.

If you own an Android smartphone and have lost it, you can choose to block it with the help of an IMEI number. By simply contacting your service provider, you can get your stolen phone blocked and hence, protecting your privacy. IMEI is valid for GSM, UMTS and LTE mobile networks. IMEI number can checked from the following four places:

Purchase bill: it has IMEI printed on it.
The box of your mobile phone: IMEI would be printed on it too.
Under your mobile phone’s battery: an sticker would be printed with your phone’s IMEI.
And your device itself: *#06# will show the IMEI on any mobile phone.
But what to do when you get in a situation where you lose your Android device and have no longer the access to any of these things mentioned above? Not a big hassle, here is some easy solution which would help you recover your phone’s IMEI and perhaps would help you locate it too.

How to find stolen Android phone’s IMEI:
We would be needed to sign in to the Google account as it is required for every other task on Android. With the help of Google Dashboard we would locate the IMEI number of our stolen/lost Android mobile phone.

Go to Google Dashboard and sign in with the same Google account that you had entered in your lost Android device – important.
Click on the Android section and you will see a list of all your Android mobile phones that are connected with this account.
From that list then, you can easily check your device’s IMEI and some other basic details like last activity and the registered date.

How to add your mobile number to your phone

Ok so lately there have been a fair few posts asking why the GG sim does not have the mobile number on it and if its possible to have it on the sim/phone, a few people have been replying with "its not possible" but it is (even for Android phones) or "just create a contact with the number" but if you run any apps that require access to the phones number this will not work :smileysad:

So here is a little guide on how to do it, just needs a bit of effort and in some cases temporary use of another phone. Please note that if using someone else's phone you will need to check that the SIM card size on the borrowed phone is the same as yours.

First thing to do is goto "My giffgaff" and get your phone number (you need to have an active sim for this) then check the phone list below for instructions on how to enter it.

Please not that on some basic models you may lose your call and sms history.

List of phones capable of manually entering the number correctly

(will update this list if people kindly report back how their phone does it)

Iphones: Goto Settings> Phone> Press My Number> Enter number> Press Save> Press Home> Job done!

(iPhone 5 takes a nano SIM, iPhone 4 and 4s takes a micro SIM, iPhone, 3 and 3gs take a normal SIM)

Iphone with uneditable number: - See this post for how to fix.

Sony Ericssons: Goto Contacts> Press More> Select Options> Special Numbers> My Numbers> Select "My mobile" and enter your number > Press save> Job done!

Nexus 5: See this post.

Android phones not listed above:You have 3 choice

Take your sim out and use another phone that is capable of doing it

Install a rom capable of doing it, CyanogenMod 6 (and up) roms (including FroydVillain) can change their SIM phone number by going to:

Settings > Call settings > Additional settings > My phone number

Download This app (the app only works on 2.2 and above) it can also be a bit flakey from reading comments so its up to you if you want to try it
Ok so once you have it set in the right place if you move your sim over to another phone it should automatically be set in any new phone

For android users instead of seeing "unknown" this is what you will now see in Settings> About phone> Status

Which now means if you add yourself as a contact, add the phone number and a pic you should now get your pic instead of the grey android box in the msg app like

Health problems in Smartphones use

Technology comes at a cost. It is not just about the monetary costs. In this article, I put down some health related costs that come with using or overly using smartphones. In using smartphones, you have to be smart else you would end up with one or more of the following health problems.
Health problems caused by Smartphones

Text Neck
 

Text Neck is a term used by doctors or physicians to describe the spinal disorder arising out of excess usage of smartphones. Normally, if the head is placed upright, there is no stress on the neck part of spine. But to read and text on smartphones, people tend to bend their necks up to 60 degrees. This increases the pressure on the neck. Long term usage of smartphones bring forth neck pain related to spine and hence, can be called spinal disorders. According to a survey published in Washington Post, around 80 percent of adult users suffer from this text neck pain.

The best way to avoid it is to bring up the phone to the level of your eyes and look straight into it. You need to make it a habit though it may look awkward. Another solution is to lower your eyes instead of bending your neck.

Vision Loss
 

Reading small fonts on a smartphone can disturb your vision permanently. This problem happens as your eyes are strained constantly by looking at the blue light coming out of the smartphone. Reading or using smartphones during absence of external light further boosts the problem. Your vision becomes poor and you might have to go for glasses.

The best way to avoid this is to look away from smartphones at regular intervals. Look at something far off and focus on it for a while before returning to the smartphone screen.

Wrist Problems
 

Another problem that comes with over usage of smartphones is the wrist problem. The way we hold smartphones for long durations, strains the wrist. People usually hold their phones using last three fingers and the thumb while using the forefinger for performing actions on the smartphone screens. Retaining the posture for longer durations every day tends to create pain in the wrist.

It is better to keep on changing the posture of phone when performing tasks like reading. You can put down the smartphone while lying on the bed or in the lap while sitting on a chair and look down at it instead of always holding it in your hands.

Numb Fingers
 

Similar to the above problem and for the almost same reasons, fingers of smartphone users become numb and produce a tingling sensation. Holding the phone places stress from the elbows to the fingers. The hands above elbow experience slower blood circulation and if not corrected immediately, can have long lasting effects. The forefinger too experiences the same and becomes numb after a while.

Instead of persisting in the same posture, it is recommended to put the phone away for a while. Then perform some movement of arms and fingers so that the feeling goes away. I would advise keeping away the smartphone for at least one minute every fifteen minutes of usage when reading or texting. That would avoid permanent problems that may arise due to persistence of prolonged usage like when reading books on the phone.

Five security risks introduced with smartphones in the enterprise

Sometimes, it's hard to identify the line between smartphone and human; the devices have become so ubiquitous and so visible that they often seem to be nothing more than an extension of flesh, an additional Borg-like appendage that assimilates the user's attention. This is apparent everywhere we go -- stores, the mall, restaurants, and even, unfortunately, behind the wheel. People text, tweet, talk, email, kill pigs, and get kicked off planes, all in the name of staying connected.

Although smartphones have affected our lives in many ways, there is one place that must be warier than most when it comes to embracing these culture-changing tools: The enterprise. Used without care or control, these mini-computers have the potential to wreak havoc and leave an organization at risk. In this article, I'll discuss five issues that should be at the top of every CIOs mind as the question of smartphones is bandied about.
Insider theft of information

Many of you probably know how Sgt. Bradley Manning was able to steal classified material and pass it on to Wikileaks. If you don't, here's how he did it: He carried rewritable CDs containing Lady Gaga songs and rewrote them with downloaded documents. During his workday, he "listened and lip-synced to Lady Gaga's 'Telephone' while exfiltratrating [sic] possibly the largest data spillage in American history."

That was accomplished with rewriteable CDs. Now, take a look at your smartphone. How much capacity does it have? 8 GB, 32 GB, 64 GB, or more? Does it have an SD card slot too? Just imagine how much data could be stored on that device in one visit. Getting document data on some devices is a bit harder than on others, but it's far from an impossible feat.

As mobile devices become more ubiquitous, organizations need to consider the ramifications for this kind of activity and apply organization risk management policies in ways that are appropriate. There really isn't any specific guidance here; it's specific to every organization.
New malware opportunities

Smartphones provide fertile ground for enterprising criminals and ne'er-do-wells intent on ruining someone's day. Earlier this year, ZDNet reported on the rising incidence of infection across smartphone platforms and provided some specific steps that users can take to protect themselves. Recently, CBS News ran a similar story.

Things aren't nearly as critical as they are in PC land, and with no clear de facto standard mobile operating system, it's a bit more difficult and somewhat less compelling to exploit mobile operating systems at present. I fully expect this to change in the coming years.

To mitigate, where appropriate, require users to run anti-malware applications on their mobile devices.

Additional wireless attack vectors

Although vendors generally patch security holes as they are identified, in the interim period, users remain at risk. Earlier this year, security researchers discovered a serious Android exploit: "The exploit is capable of reading and writing files from an Android's SD card or system partition as well as uploading user data over the internet."

Now, imagine that your organization doesn't yet have policies prohibiting sensitive information from being stored in unencrypted areas of a mobile device. This is just one example of ways that the mobility aspect of smartphones can work against them. Wireless devices generally have at least three different wireless access opportunities: 1) Cellular; 2) Wi-Fi; 3) BlueTooth. Any door can be opened by a person who is determined enough to do so.

To mitigate, ask users to disable certain wireless doors if they are not in use.
Loss of sensitive corporate data

This one is more common that malware infestations on corporate mobile devices. Smartphones are easy to lose and easy to steal. They're so portable that someone can simply grab it and go with the owner being none the wiser until it's too late. As people use these devices more as business tools, the risk of accidental exposure of sensitive information rises significantly. Even something as simply as synchronizing email with a smartphone increases the risk that data will make its way into the wrong hands.

Good corporate policy and tools to compartmentalize sensitive information should be considered as safeguards against this all-too-common threat.
Inability to appropriately control personal devices

In many places, people are bringing their personal devices to work and demanding that they be able to use them in place of corporate-provided services. Organizations that lack policies for handling these devices leave themselves at higher risk for not being able to take swift action when necessary. For example, are you allowed to simply remotely wipe a person's personal device if you believe that it has been compromised, that person has left the organization, or the device has been lost or stolen?

By implementing clear guidelines for what can and cannot be done with corporate information in regard to mobile devices, organizations can maintain the strict controls that are necessary to safeguard information. If users don't want to allow IT to wipe their personal devices, but that's what corporate policy requires in certain situations, then that user can be more easily denied the opportunity to use a personal device.

If you haven't already, now is the time to get mobile policies in place and make sure they're clear and well-communicated.
