From the Android Forums: Spam in my EVO 4G

26

jair asks in the Android Central forums:

Hello guys,

Today, April 12th around 1 p.m. CDT, I started getting this strange plus green symbol on my EVO 4G notifications bar (I will be attaching two pictures here) Has anyone perhaps mention anything about this? Notice the green + sign in the notification bar.

Here is when I open it: there is a spam about dating and girls site or something. Please help what should I do to get rid of this and protect from happening again, also this will help others to prevent get the same spam.

Thank you!

Ugh. It looks you ran into what's commonly called an "airpush" ad. They come from certain advertisement SDKs that put that notification bar spam there, hanging all out and trying to get you to click it. They are inherently evil, like Reagan in the Exorcist kind of evil. Good thing finding which app is doing it is fairly easy.

Grab Lookout Ad Network Detector from the Google Play store. It's free, and will scan all your apps to see what they can, and can't do. One of the apps that gets listed as able to place ads in the notification bar is the culprit. Uninstall it, and never look back.

It's worth noting that just because an app can put ads in the notification bar doesn't mean they are doing it. Different capabilities come from different ad SDKs, and some folks may have the ability and aren't using it. We call them the good guys.

From the Android Forums: Can my Rezound get official ICS if I don't have Verizon service?

9

af250xxl asks in the Android Central forums,

Can my Rezound get the official ICS update if I don't have Verizon service? I removed the Rezound from my account the day after I activated it because I don't want to pay the $30 data fee. Will HTC or Verizon have a website for people to download the ICS update to a PC or directly to the Rezound?

Great question. The short version is no, but that doesn't paint the whole picture. Some Android phones don't require the user to have an active service plan to get an OTA update, but some do -- the HTC Rezound, like most phones on Verizon, is one that does require it. We're not sure of the full reasoning behind this practice, only that it helps control the OS versions from a customer service and tech support standpoint. My tinfoil hat side says it's done to convince users to keep their service active, but that's just paranoia talking.

But all is not lost. There will be a file released by HTC and sent to Verizon service technicians called an RUU (ROM Update Utility), and it is a manual way to update the phone via the USB connection. Carriers have Android geeks working for them, and these sort of things tend to get leaked out to the community rather quickly. Using the RUU and a Windows computer, you would be able to wipe and re-flash your Rezound to the latest version. Talking to the folks in the HTC Rezound forum is a good place to start, and they will know the minute any new RUU leaks out. Keep an eye out for it and you'll likely be able to do exactly what you're hoping to do.

How to cut down a SIM card for the HTC One X (and any other phone)

20

This one's important for those of you looking to switch to the HTC One X (as well as a number of upcoming phones). You're going to need a micro-SIM, which as the name suggests is smaller than a larger (and more prevalent today) mini-SIM card. If you're rocking a GSM phone right this second, there's a good change you're using a mini-SIM. If you've got an iPhone 4/4S on AT&T, you've already got a micro-SIM. 

So, a couple of ways to go about getting a micro-SIM. One is to just ask. Head to AT&T or T-Mobile or whomever your carrier happens to be, and tell 'em you need a micro-SIM. (If they don't know what one is, it might be time to consider switching carriers. :p )

The other way is to cut your own. Sounds scary. Sounds dangerous. 

It is neither.

Samsung Galaxy Nexus my way: Jerry Hildenbrand

28

The other night on the Android Central podcast a great idea was born. Someone, and forgive me for not remembering who, wanted to know how our phones are set-up. I promised to kick off a series from the various AC staff members showing just what software we have running on our devices. I trade back and forth between the Samsung Galaxy Nexus or the T-Mobile Galaxy S II (dat cam!), but both are set up the exact same way. One is just more TouchWizzy than the other. Hit the jump and I'll break it down.

How I back up my stock, unrooted Galaxy Nexus

27

I get this question a lot: If my Galaxy Nexus is unrooted and running the stock ROM, how do I back up it via a custom recovery?

It's pretty easy, actually, and it goes back to our method of manually applying a stock update. You're going to need a few things (and chances are you've got them already):

So here's what you do:

  1. Download the custom recovery into the same folder as your fastboot file. (I like to rename mine just to keep things short.)
  2. Reboot your phone into the bootloader, either by turning it off and holding vol-up/vol-down+power, or reboot from the command line (adb reboot bootloader).
  3. Plug your phone into your computer if it's not already. (Type fastboot devices to make sure your computer sees it)
  4. In the command line, type fastboot boot xxxxxxx.img (where xxxxxxx is the name of the custom recovery you saved).

And that's it. You'll have booted into the custom recovery, and from there you can do a full backup, or restore a backup, or wipe the phone. All without rewriting anything. If you need a little more hand-holding, there's some video after the break.

LG introduces new wireless charging solution in Barcelona, arriving stateside soon

8

In addition to a flurry of new smartphones, LG also introduced its latest innovation in wireless charging this week in Barcelona. The WCD-800, a cradle that supports both vertical and horizontal charging, is the company's latest inductive solution, and nearly doubles the charging space of the previous model, the WCP-700. Resting your phone vertically will allow for quick phone calls and text messages, while charging the device horizontally will allow for multimedia playback and unobstructed views of video and photos.

LG says that by using magnetically-produced electric currents, the WCD-800 is as effective and efficient as typical wired chargers. It'll be compatable with all of LG's recently released devices as well as any device compliant with the Wireless Power Consortium's Qi standard. You'll be able to get your hands on one here in the States sometime in the first half of the year. LG's full presser can be found after the break.

What is a widget? [Android A to Z]

11

What is a widget?  In Android, the word widget is a generic term for a bit of self-contained code that displays a program, or a piece of a program, that is also (usually) a shortcut to a larger application. We see them every day on web pages, on our computer desktop and on our smartphones, but we never give too much thought into how great they are. Widgets first appeared in Android in version 1.5, and really gained traction thanks to HTC's Sense-flavored version of the operating system. Prior to the release of the HTC Hero and our first taste of Sense, widgets were functional, but pretty bland in appearance. Since then, OEMs and independent developers alike have done some marvelous things with widgets, and it's hard to imagine using Android without them.

Android widgets come in all shapes and sizes and range from the utilitarian 1-by-1 shortcut style to full-page widgets that blow us away with the eye-candy.  Both types are very useful, and it's pretty common to see a widget or two on the home screen of any Android phone. A full-page widget, like HTC's weather widget for late-model Android phones, tells you everything you need to know about the current conditions, and is also a quick gateway to the weather application where you can see things like forecasts and weather data for other cities.  At the other end of the spectrum, the Google Reader 1x1 widget watches a folder in your Google Reader account and tells you how many unread items there are, and opens the full application when pressed.  Both are very handy, and add a lot to the Android experience.  

Most Android phones come with a handful of built-in widgets.  Some manufacturer versions of Android offer more than others, but the basics like a clock, calendar, or bookmarks widget are usually well represented.  This is just the tip of the iceberg though.  A quick trip into the Android Market will dazzle you with the huge catalog of third-party widgets available, with something that suits almost every taste.  With Ice Cream Sandwich supporting things like higher resolution screens and re-sizable widgets, it's going to be an exciting year seeing what developers can come up with.

What is USB? [Android A to Z]

9

What is USB?  USB stands for Universal Serial Bus, and is a standard for connectors, cables and protocols used for data transfer and power between a computer and another electronic device.  It was developed in 1995 to allow a single connection method for things like computer keyboards, mice, and printers as well as connected devices like mp3 players and cameras. A standard USB interface has four wires (USB 3.0 has eight for double the data transfer), with two acting as power leads and two for data transfer. Commercial applications have up to eight wires and connection points, and can also provide 12- or 24-volt power in addition to the normal 5 volts. You'll see these sort of systems in cash registers and commercial barcode scanners.  

What we're most interested in is the implementation in mobile devices.  Most mobile devices in the world use USB 2.0 for data transfer and/or power supply. In China, laws have been passed making manufacturers keep to the USB standard for data transfer and power, and in December 2011 a law was written that all mobile phones will be able to use the same charger, with micro-USB as the standard, by the European Committee for Electrotechnical Standardisation. This only affects phones -- tablets and laptops are exempt because they have different power requirements.

Most new Android phones you'll buy have a microUSB (like the picture above) connector. The data cable will have a small plug to insert into the phone on one end, and a standard USB connector to plug into your computer. This cable will allow for data transfer -- to copy pictures or music or do a little hacking, as well as 5 volts to charge the device.  Some older models have a miniUSB connector, which does the same thing but with a different, slightly larger, port. MicroUSB is a more robust connector, being rated at 10,000 "insertion cycles" so both the port on the phone as well as the cable should last longer. Some devices need a non-standard USB connector, like the Galaxy Tab 10.1 (or nearly every other Android tablet). Internal design doesn't permit a standard microUSB connector to fit on the board, so a wider, thinner plug and port combo was used.  Also, some tablets can't get power fast enough to charge via a USB connector and use a separate DC socket and adapter for charging. For devices like the iPhone that have a non-standard connection port, an adapter can be made to allow them to comply with European mandates of a single charger solution.  

Lastly, some phones use the microUSB interface for other things besides data transfer and power.  Seeing HDMI output provided through a MHL (Mobile High-definition Link) is becoming pretty common, and allows a special adapter to be used to provide high definition video to stream out to televisions or computer monitors. These adapters can be purchased for about 15 dollars (US) and allow a standard HDMI cable to connect to your phone.  

We've seen other connection methods come and go, and new ones are always being worked on, but USB offers relatively high-speed data transfer, is adaptable for various power needs, and is likely to stick around for a long time.

What is tethering? [Android A to Z]

21

What is tethering?  Besides the grounds for a giant debate about ethics (the kind that you can only find on the Internet) tethering, in this case, means to share the Internet connection from your phone with other devices. There are several ways to accomplish this -- connecting your phone to your computer via USB, setting up your phone as a wireless hotspot and router, and sharing a data stream over Bluetooth. All these connection types are built into Android, with native Bluetooth tethering new in Ice Cream Sandwich. Of course, different manufacturers can, and have, modified things so that these options are excluded -- at the behest of the carrier, of course. We'll talk more about why in a few minutes.

Tethering itself is pretty easily done.  USB tethering involves installing device drivers (Windows only) and plugging in your phone to a high-speed USB port on your computer, then using your computer's built-in connection manager to use the phone or tablet as a USB modem. Bluetooth tethering will need the phone paired with the computer, and the connection type set up correctly in your computer's Bluetooth settings. Wifi is the easiest way -- you just turn it on and connect as you would any other wireless hotspot.

Except that many carriers, especially in the United States, have blocked tethering this way.  

You see, your carrier wants to charge you a premium to use your data plan from any device besides your phone.  Nobody likes it, but it's in the terms you agreed to when you signed up. They have all sorts of ways to block tethering on their end, and they are pretty diligent about it. Android hackers and developers also have found ways to work around these blocks, and it's a big cat and mouse game. An inside source with one the the biggest cellular carriers in the world has specifically told me that if your usage pattern draws suspicion, there is no current method that can't be detected by you carrier, including the newer VPN methods. If you do it a lot, without paying the extra fees associated with it, you'll get caught.

We're not going to judge anyone, and a few of us here at Android Central think charging extra for tethering is silly -- especially with data caps. Just know what may happen before you start so you don't get caught unaware.

Erase your Android device before getting rid of it [Android 101]

18

With the news today that Motorola accidentally shipped out 100 refurbished Xoom tablets without properly wiping the previous owners' information, it's worth a reminder of what you need to do when selling, returning or otherwise disposing of an Android device.

With any electronic device -- computer, tablet, smartphone or whatever -- it's important to keep your personal data secure. That means within your control, not just floating around for anyone to see. And that means not just tossing something in the trash when you're done with it. Or selling a device in the same state as it was when you finished with it.

You must remember to wipe.

Android makes it pretty easy to wipe -- or hard reset -- though it can vary slightly from device to device, hiding the rest option under strange menus. The best thing to do is to go to your settings menu and look for a reset option.

  • On the Galaxy Nexus with Ice Cream Sandwich, it's under the aptly named "Backup and Reset" option. Choose "Factory data reset," and you're done.
  • On recent Motorola phones, look under the "Storage" option in the settings menu. That's also where it is on the new LG Spectrum.
  • On Samsung phones, go to Settings>Privacy and choose factory reset.
  • On Honeycomb tablets (like the Xoom), it's under >Settings> Privacy.

Point is, the option to hard-reset is there, you might just have to look for it. (Note to manufacturers and carriers: Let's standardize that, shall we?) If you'd prefer, you can also wipe from the stock recovery, but that really happens when you reset from the menu. (Read our Android A to Z listing for recovery for more on that.)

And this is important, too -- don't forget your microSD card. Data on it -- including pictures and videos, as well as some application data -- generally isn't erased with a factory reset. Some phones give you the option to format the SD card at the same time you erase the rest of the device. If not, you'll want to connect the device to a computer and format the card. If you're really paranoid, use one of those overwriting formatting programs. Or at the very least, just take it out of the device you're getting rid of.
