I have this phone for almost a year and you just can't understand how i am dissatisfied with this mobile phone and android os. I have 2 very big problems that frustrate me and i can't deal with. 1.First is SOFTWARE UPDATE. Even after factory reset my phone doesn't have option "check for software update" (or sth. similar) in general settings/about phone. All other phones of my friends, have this option. I tried to update firmware via kies but it non-stop says: "not enough disk's free space" (minimum 3000 mb required)" even if i i did everything to fix it (according to online advices and help). 2.Second one is famous "Error downloading. There insufficient space on the device". I tried EVERYTHING that i found online. Cleared data and cash, uninstalled google play update and even cleared download manager (which just helped me for apps that are up to 25 mb big) but main problem (for bigger apps) stays unsolved. And you just can't understand what amount of rage is in me all these months, but oh, especially now after factory reset that didn't help, but deleted all my data making me sending it to the bad phone again. I have nothing to say anymore.
