This article works perfectly. It is a little thicker than the original cache. So if you use a shell, it will fit properly on your smartphone. In my case it was a Ballistic Tough Jacket Maxx. This shell is thick and the Qi charging does not work through. This is normal. It would make sense that Samsung equips its smartphone with this SystemThe Qi of origin to the shells can be manufactured accordingly and for that Qi is usable on greater thicknesses (although this increases heating and reduces the effectiveness of the load). Otherwise good article.
