Having suffered Apple''s monopolistic stranglehold on mobile devices, I was stuck with an iphone and an ipod, so I saw with relief the liberating announcement of Google''s liberal Android platform that would enable me to get rid of the irritating itunes straightjacket by being able to simply drag and drop content. Thus I bought an Android mp3 player that works fine, and then I bought this phone from T-Mobile but soon my initial enthusiasm was dampened by the phone''s inferior quality and Apple-like restrictions.The best thing about this phone is its bright screen but this phone has a mind of its own and, among other irritating things, although I set Brightness at maximum, NOT AT AUTOMATIC, it goes to Automatic and dims whenever it feels like it. This phone also overheats markedly after half an hour or so of usage. It also does other things on its own: useless programs pop up on their own and the worst is when the phone suddenly freezes at least once a day. To unfreeze you need to either turn it off or remove and re-install the battery. Contrary to other phones, like the Sony Ericsson, the alarm does not ring when the phone is off, so you have to keep it ON connected to power all night if you need to use a wake-up alarm. The phone has no hardware Home button, something that makes it difficult to answer the phone having to grope for the virtual button.Some of the programs that pop up on their own are not only pre-installed, but Samsung does not allow you to remove them. They are not only useless but also irritating. It seems counter-productive and unfair that you own a phone but you are not allowed to remove some of the unwanted garbage that, in addition to wasting your time by popping up, they waste memory space. The iphone that I did not like gave me the option of many keyboards including Greek, which I need for scholarly purposes. This Samsung phone offers only 5 European language keyboards and an Asian.I bought this phone thinking I would be able to make Skype video calls but that was not possible because it was equipped with the old Froyo Android software. The people at T-Mobile said Samsung would soon offer upgrading to Gingerbread that would solve the Skype video call problem. Nobody knew when the upgrade would take place; so much for T-Mobile and Samsung customer service. One day I saw on line that the upgrade was available and took me quite a while, owing to poor instructions, to finally raise this phone to standards long-enjoyed by iphone owners. Samsung has grown too much and too fast for its britches and as a result it ignores or cannot keep up with the increased demand for service.Bottom line: I am not going back to iphone and its oppressive proprietary restrictions; I will await the appearance of Google smartphones, following the acquisition of Motorola by Google, in the hope that such phones will be as well-performing as iphones and will include Google''s extensive language capabilities as now available in Google News and other Google programs.
