Stay Safe from Mobile Radiation

The smartphone has made our life even more worthwhile, but technology has its side effects too. Ever since the device became more portable (and literally “handheld”,) it has been posed as a potential health hazard, due to the electromagnetic radiation it creates during a call or data network access. The fact worth taking note is that according to the WHO (World Health Organization), this effect is possibly carcinogenic. Do not freak out yet, because it’s your smartphone that can help you alleviate this radiation effect.

How?

Like always, there is an app for that. Tawkon is a smartphone app that monitors in real-time your exposure to mobile radiation and alerts your accordingly with simple steps to minimize the effect.

Download and launch the app, and get ready to be less worried about potential radiation. The app sits in the notification area and the icon changes colors (green,yellow and red) to notify the status of radiation exposure. This also works while you are on a call and how a Bluetooth headset (or loudspeaker) can help you safely make a call if there is a rise in radiation level.

The Prediction mode maps danger zones/conditions during phone activity and it learns with time. The time range can be as low as the last call duration and range up to 6 months. This serves great if you are determined enough to avoid health hazards.

The app also serves on a global perspective by creating a radiation exposure map. The map is extensively updated with radiation data generated by users, which in turn helps users who wish to travel to a certain area and check the radiation levels it possess.

Tawkon certainly is a great app that effectively does what it promises to. Anybody who is moderate to highly dependent on their mobile phones should consider using it. The app is currently available for Android, iPhone (jailbroken) and Blackberry.

How do I delete contact emails from my Gmail contact list?

How do I delete contact emails from my Gmail contact list?

As online acquaintances come and go, your digital address book may need to be updated from time to time. If you’ve got that “special” someone you’d rather not hear from again, or just need to clean up old contacts that aren’t in use anymore, the Gmail service lets you remove unwanted entries from your address book.

Gmail’s interface has recently been revamped and streamlined, so the location of various options such as deleting saved contacts have been moved around. After logging into your Gmail account, click the large red “Gmail” button at the upper-left side of the screen, just below the “Google” icon. Select the “Contacts” entry in the list of options. Depending on how you have your account setup or what options you were previously using, the “Gmail” button may instead read “Tasks” or “Contacts.”

Each of your contact lists are located directly below the red “New Contact” button at the left side of the window. Click the name of the specific contact list you want to access, such as “My Contacts.”

Find the name of the contact you want to remove in the listing at the center of the window. Click the check box to the left of each contact you need to delete.

If you instead want to delete every contact in the currently selected list, click the box icon at the top of the list of names and select the “All” option.

To delete the selected contacts, open the “More” box above the list of contacts and click the “Delete Contact” button.

Anytime you delete a contact, Gmail provides an option to immediately undo the change just in case you selected the wrong option or deleted too many contacts. If you want to restore the contacts you deleted, click the “Undo” button that appears at the top of the screen immediately after choosing “Delete Contact.”

In the event you later change your mind or discover you still need a specific contact that was previously deleted, it is possible to restore removed entries later on down the line. Open the “More” box again and scroll down to the “Restore Contacts” option.

Click the radio button for the timeframe you want to use to restore your contacts, such as “10 minutes ago” or “1 Week Ago.” If you want to go back even further, click the “Custom” button and type in the number of days to go back. Click the blue “Restore” button to restore any contacts deleted after the selected timeframe.

Which Version of Android Is Best?

Android has a lot of great features, including customization, open development, and tons of devices to choose from. One thing that’s a problem though is something called fragmentation. Fragmentation means that instead of most Android devices running the same basic operating system software, there are many, many versions. So which Android version is best and what should you avoid?

It’s pretty simple:

(The higher the number, the more recent the version of Android. The codename (the words in parentheses) is a name Google assigns each version and is named after a snack)

Below Android 2.3: (Froyo, Eclair, Donut) Avoid it like the plague. While there is nothing inherently wrong with lower versions, the ones below 2.3 won’t support many modern applications. Besides, you don’t want to spend money on something already so far out of date.

Android 2.3: (Gingerbread) With a redesigned UI and support for integrated social networking and voice over IP calling, this is the lowest version of android I’d accept. This version includes 2.3, 2.3.x (x represents small improvements like 2.3.3)

Android 3.0: (Honeycomb) This version of android features another redesigned UI, primarily focused on tablet computers. This version also added USB support for plug-in devices like keyboards, joysticks and other devices. This version includes Android 3.0/3.1/3.2.x (once again, x represents small improvements like 3.2.6).

Android 4.0: (Ice Cream Sandwich) This is the latest version of Android, and includes an improved UI, optimized dual and quad core processor support. This is the version of Android you want, as it offers the latest Android experience. This version includes Android 4.0.x (x represents small improvements like 4.0.1).

Check with your device manufacturer to see if they offer any upgrades for the version of Android you have installed on a device. HTC and Samsung both have been pretty good about offering upgrades when possible, but the latest versions of Android can usually only be found on the newest hardware as many lower cost device manufactures see no benefit in offering free upgrades once the product’s replacement is out.

Changing Your Android Wallpaper

    

                  Changing Your Android Wallpaper

It’s amazing how far technology has come in such a short time. It seems every few years some shiny new invention changes the way we see the world. Smartphones are the latest of these game changing technological wonders.  Sleek, stylish, powerful, and almost completely customizable.  The layout of the homepage on your android phone says a lot about you, in fact the only thing that says more is the picture behind it.

Here are a couple ways to change the wallpaper on smartphones using the Android operating system. 

On a blank area of the home screen, lay your finger down gently across the screen for 3-5 seconds. A menu will pop up. From this menu select wallpapers. 

 

From the next menu you can select from your gallery, live wallpapers, or wallpaper. The latter is just some stock wallpaper that comes with the phone.  Live wallpapers are fun to look at, but will drain your battery much faster. So rather than search for a power outlet several times a day, let’s stick with a more static background for now.  Choose gallery.  This will take you to your photo albums.   Flip through your photos until you find one you’re happy with, then tap the picture.  The yellow square in the center of your selected picture is for cropping. You can drag the square around the photo or place your finger on the sides of the square and by moving it up or down change the size.   Whatever is inside the square when you press the save button is what your homescreen wallpaper will be. Keep in mind when choosing your wallpaper that your homescreen is separated into 5 parts, and not all are visible at the same time.

 

You can also grab a wallpaper picture straight off the internet while browsing.  Just place your finger over the picture you want as your wallpaper for 2-5 seconds. Select set as wallpaper from the menu. Your phone will automatically crop the picture for you.
