Have this phone now for about a month in operation; mainly for SMS and calls and the phone can attest an almost impeccable performance possible. The keyboard has a noticeable and good tactile feedback, is also for big fingers like my useful and probably preserved because my keyboard still looks like right out of the store, despite intensive use. Good is also the patron of the mobile phone by an aluminum cover the back. The menu navigation is no mystery and is loosely used without manual; Here agrees the multiple statement read that Samsung has oriented (the menu) to the clear structures of previous Nokia phones. Unfortunately modern Nokia phones (C5, C7, X6 etc.) have now become a disaster since. Highly Satisfactory is also the stamina of the mobile phone to charge the battery. Keeps a good week by at an average of about 70 minutes. Discussions during this period and 50 SMS. Otherwise, it is also well equipped, including Bluetooth, radio function with transmitter display (RDS), calculator, calendar, alarm clock, MP3 player, a stereo headset is supplied, which also has a volume control on the headset, otherwise you can use any other headset because the phone has a standard 3.5mm jack; 3.2 megapixel camera phone, etc. can be used worldwide because it can operate in four frequency bands and can be expanded with microSD cards up to 16GB. One point deduction gets it because of a peculiarity that interferes when they will stand out rarely, because when you enter unknown words in the dictionary (write the SMS) the words are limited to 18 characters; a strange quirk, but tolerable, because our language certainly not too many yet know longer words.
