If you would prefer not to be told every time an Application has been updated, open the Android Market - Menu - My Apps. Then Menu again. Then Settings. Under General settings, untick the Notifications option.
To view information about your battery and CPU go to your phone dialer and type in the following code: *#*#4636#*#*
On most Android phones, when you rotate the phone when on Homescreen mode, the Homescreen stays in Portrait mode. One way around this is to install a third-party Launcher Application which allows you to customise your phone in many ways.
One popular launcher is called GoLauncher. Or alternatively, open the Android Market and search for the word Launcher.
While the stock standard keyboard is fine, there are much better keyboards available. First, you need to go to the Play Store and download one. Try searching for the word 'keyboard' and you will see a number of options.
One of the best keyboards is a keyboard called Swiftkey, which is a top-rate App.
Download your chosen keyboard and go through any install steps that you are presented with.
If you see a warning saying the keyboard will collect all information (including credit cards) just ignore this. This is just a security feature that Android shows for every third-party keyboard that you install.
If you have just purchased an Android device, then you may want to copy your contacts from your old phone. The easiest way to do this is to Export your old contacts to a CSV (Comma Separated Values) file and save this to your PC. You may need to install the correct software for your phone first in order to do the export.
Then, if you don't have a Gmail account, sign up for one.
Once that's done, open Gmail. Go to Contacts, then press More - Import. Then import the CSV to your Gmail contacts.
Then on your phone, open the Contacts App. Press Menu and then Sync Contacts. This will pull the contacts from Gmail to your phone.
Most Android phones only come with a fixed amount of homescreens. There is a way around this however.
Go to Android Market and search for 'launcher'. These are third-party user interfaces that allow you to customize your phone in many ways. Most of them allow multiple homescreens.
A very popular launcher which supports multiple homescreens is GoLauncher EX.
In the Calendar App there is no Year view along the top of the App. You can however use pinch to zoom gestures to zoom in and out of Month and Year view however.
This is useful if you want to quickly jump backwards or forwards through a few months at a time.
If you are running low on phone memory, you can look for your largest applications to uninstall. Go to Settings - Applications - Manage Applications and press Menu. This will then filter your apps by memory use
To delete all contacts, there a number of methods you might need to try. Note that the first two of these may be disabled on some networks/carriers, or Android versions.
1) Go to Settings - Applications - Manage Applications. Then chose All at the top. Then scroll down to Contacts Storage - B21Clear Data.
2) Go to Contacts. Then press Menu - Delete. Then press Select all (at the top) and then Delete again.
3) Go to Settings - Accounts and sync. Then untick Background data and Auto-sync. Then go to Gmail (or an account that your phone syncs with) and delete all of your Contacts from there. Then re-sync your phone.
4) Download an App called 'Delete All Contacts' and use that as a last resort.
These methods above will delete contacts from the Phone only, not the SIM card.
To bookmark a contact on your homescreen, long press on the home screen background and select Shortcuts. Then select Direct dial.
If you call someone regularly this can be useful as you will have a shortcut to them handily placed on your homescreen.
