I still use mine as a daily phone. I have just about filled the 64G sd card with music, & I listen to it in the car via the FM xmtr. Neither of my cars has bluetooth. I use a number of other apps on it often, too, like Firefox, Modrana, PyOBD, Symfonie, gpodder, cuteRadio, etc. I've never had a problem with the USB port, but the slider switch is now inop & the screen is getting eczema & is having trouble reading touches at the upper left corner. I literally cannot function without the internet clock radio created via shellscript, alarmed, & kmplayer. I have never been able to wake up reliably until I put this together.
