How do I toggle Wi-Fi, Bluetooth, etc?

As nice as it is to have Wi-Fi, GPS, or Bluetooth running on our devices, it’s not always necessary. Every once in a while we need to turn on off or on to preserve battery or to connect with another device.
Early and existing versions of Android allow for easy access and toggling of our connections and options through the settings. Open the app tray (usually an icon that looks like small squares) at the bottom of your phone and scroll until you see Settings.
Typically, the first things you’ll see here are wireless and network settings and you’re but a quick tap away from turning on Wi-Fi or enabling Bluetooth. New versions of Android (4.2) have a second dropdown menu from the notification bar which can be accessed by swiping the right hand side. A menu of quick settings appears on top of the home screen letting users hop directly to the same toggles. Select handsets also make it pretty easy to access settings in the notification bar that displays your missed calls and email alerts. Simply swipe down from the top of your screen and you may see some of the more common settings right there.
Finally, there’s a chance that you can also hit the menu button on the homescreen of your Android to reveal settings. Samsung does this for a lot of their devices, providing one less hurdle between you and turning on Bluetooth.

How do I uninstall apps or games?

Would you like to change that background image (wallpaper) on your phone to something different or more personal? That’s really easy to do and there are usually a few ways to do so.
The first way we would recommend trying is to long press (tap and hold for a few seconds) on the home screen to see if a menu screen comes up. Should that not work then move on to the next method. Open the app tray (usually an icon that looks like small squares) at the bottom of your phone and scroll until you see Settings. Open that up and look for an option for Display.
Many, but not all, handset makers list the wallpaper settings here. HTC phones, for instance, put their wallpaper settings under Personalize, which can be accessed from the notification bar or by pressing menu on the home screen. When in doubt, long press or tap the menu button to see what options pop up.

Where do I find apps and games

You finally got yourself a smartphone and now you’re wondering, “Where are all these apps that everyone keeps talking about?” We’ll show you how to get Angry Bird, Temple Run, and all those other popular titles.
In many cases, a new phone will feature an icon to Google Play right on the home screen. If you’ve already created an account for (or logged into) your device then you’ll be off and running. If you don’t see the Google Play icon on the home screen, you can open up the app tray (usually an icon that looks like small squares) at the bottom of your phone. Scroll through your app list until you see Google Play and there you go! A single tap and you’re off to download new and wonderful apps!

How do I add a new email account

Chances are high that when you’ll create or log into your account when you first power on your Android smartphone or tablet. For many of us, however, we have multiple email addresses or accounts that we’d like to manage from our mobile device. Be it Yahoo!, Hotmail, or some other personal account, adding a new one is no problem.
In most instances, the quickest way to add an account is to open the Settings app on your device. Scroll to Accounts and you’ll see an option to “Add New”. From there it’s a matter of entering your credentials and waiting for the sync.
Some manufacturers or versions of Android may not be so simple but, rest assured, it’s nowhere near as difficult as it sounds. Many apps, such as Gmail, let users add new accounts directly from within the app itself. Should you add a Google account (Gmail, Google Apps) to your email, you will also see the same account elsewhere on the device. This is includes, but is not limited to, Google Play, YouTube, Google Play Music, and Google Books. Once you are familiarized with the phone, you can also go in and manually adjust sync settings on your accounts.

My computer is having trouble connecting! What can I do

Check whether your operating system and wireless card support ad-hoc connections. Ubuntu is known to have poor support for these types of connections, for instance.
If you think your OS is not the issue, it may be an issue with either the tethering binaries or your tethering settings. From the main tether screen, try going to Menu->Setup->Menu->Reinstall binaries/configs.
If that still doesn't resolve your issue, it may be a problem with your allowed clients or security settings. Start tethering and connect your laptop. then from the main tether screen, go Menu->Setup. If "Activate Access-Control" is already checked, either uncheck it or check the entry below containing your laptop's MAC address. If "Activate Access-Control" was unchecked originally, try checking it and checking the entry below containing your laptop's MAC address.

Why won't tethering start on my phone

First, check that you have root permissions. When you open Wifi Tether for Root Users, you should see a message warning you if you do not have root permissions.
If you have root permissions, but still cannot start tethering, it may be an issue with either the tethering binaries or your tethering settings. From the main tether screen, try going to Menu->Setup->Menu->Reinstall binaries/configs.

I have an old version installed and get an error-message when trying to update the app. What's wrong

Some custom roms come with a pre-installed version of "Wireless Tether". If that version is located on the "system"-partition the update-process will fail. The "system"-partition is read-only and needs to be remounted (with write-premission) before removing the old app manually.
