Forgot lock pattern on android?



Solution:


Enter wrong pattern 5 times and wait for 30 seconds.
Select “Forgot pattern” and enter your gmail account username and password.
Make sure you use the same account that was used to activate the phone and double check the password by logging in to that Google account in a browser.
If you don’t have access to the original Gmail account, you will need to do a hard reset and loose your settings and apps on the phone. The data on the memory card will not be wiped though.

Long-press on any icon or widget on your homescreen and you can move it around, and other icons and widgets will shift out of the way to fit it in.

How to Equalise your music in Android



Solution:


The ability to adjust those all-important bass and treble settings has been sorely missed on Android devices - so much so that a bunch of apps have been made to enable it. It's fixed in Android's stock music player, though. Open a music file in the stock player, hit Settings then choose Equaliser. Here you'll find manual sliders, a load of presets and bass and 3D effects. Unfortunately it doesn't work for the whole device, but it will give your tunes a little more oomph.

Solution:

Install enough apps and the notification bar at the top of your Android device becomes the digital equivalent of an unending stream of ticker tape. In fact, Airpush is an entire advertising company that makes money in this way. Fortunately, each and every app you install in Jelly Bean has the option to turn this off. Go to its info page under Apps, uncheck the box labelled "Show notifications" and enjoy your empty notifications bar.
