So far I had an Android tablet. Since I've worked all my life with Windows itself, I wanted to now a Windows phone and get hoped that I can work with it like on my desktop. But that is not true, desktop programs you do not get onto the smartphone and vice versa. Apart from that, I am very confident of the handling after a short time. But almost this assessment would have been catastrophic. As I have namely the smartphone with my Windows 8.1 notebook connected caught the chaos on. The smartphone has not been detected correctly, there were errors in the device manager and in any forum I got useful solutions. Oddly enough, everything worked flawlessly on an older notebook window 8. So I came not equal to the obvious solution. I got hold of any drivers, put the notebook back to the auslieferungszusand, nothing helped. However, over the 2 days I noticed even by accident that it worked almost flawlessly as was full charged battery and were screen and off Wi-Fi. Finally, I came up with the solution, the USB port of my notebook yielded too little power, or fluctuated too much, so that the smartphone has been repeatedly recognized and not recognized then again Voltage apparently. The smartphone draws probably a lot of power when everything is on. Now I have it connected to a USB hub with power supply and can thus also the smartphone all turn without affecting the USB connection. Together with the desktop app for Windows Phone is a very elegant solution to synchronize the data. Even without the desktop app has one smartphone in explorer with all memory cards under control. It's a really very successful in part, handy, clear and powerful.
