I use The RugGear of an unknown model, which you can use only for calls and sms. Internet is not on it, but there are buttons and a powerful case. You do not believe me - I do not know bugs and system crashes. Very quickly i can open the call log and SMS history! Nothing is buggy!  :DAnd I can safely go one night - better weapons than this phone has not yet come up with! And how loud and clean the player sounds! And what a bright lantern!
I advise everyone! And in the network you can sit at home for a good computer
