Google’s new mobile phone Galaxy Nexus launched on November 17 in U.K but has many problems. Most of the people who bought it complain about it. The most annoying of them is the volume bug. Volume goes up and down auto-magically and this happens almost in every action, when the user watches a video, makes a call or listens to music. You can watch the following video that demonstrates the problem. If you want to buy a good Android phone then I recommend the Samsung Galaxy S II, avoid Galaxy Nexus. Their specifications are very similar and Galaxy S II does not have all that software bugs of Galaxy Nexus.
