For induction charging (Qi):
First, I have the EasyCHEE internal inductive Qi charging receiver (qi receiver) fixed with only a small strip at the bottom of the battery and the score 4 inserted without Samsung back cover in the Unicornhülle - that does not have clean contact ergeben.Ohne the Samsung lid there were clearer gap mass of camera and speaker, these were halved with lid. Excised So from the Samsung back cover the surface of the coil and the surface of the male components with jigsaw, Qi receiver vorplatziert as much as possible, half a millimeter less at the left contact fingers would be okay - put Samsung lid and then closed the Unicornhülle - goes without receiver to somehow fix. It's probably also with unprocessed cover, but I wanted a uniform pressure distribution. The whole is also only slightly warm, the only inter esting point is that the app Battery Monitor Widget charging in red because it differentiates between USB and Wireless store instead of green records. The charge indicator of the Android operating properly, the control LED in the top left is clearly visible, not restricted voice quality, infrared is also. I can not for the finger sensor to the pulse counter still say something, because I do not insets both. The caps sit quite tight - but I am glad that I will open it only in an emergency when I pin the rare and the headphone jack and USB hopefully must use no more thanks to Bluetooth headset, Qi and WLAN - NAS. The tape I have in front of close away.
