Flat, small bulge on the phone back,

Positives:
+ Much flatter structure than the original QI backcover "Samsung Original EP-CI950IWEGWW Cover"
+ By flat design combined with shells.
Tested with:
PSC = 1
PSC = 1
PSC = 1
PSC = 1 "" - Ladeataper bulges rear of the phone (no more lies precisely on)

Negatives:
- Phone slips on charging station (especially since Ladeadapter the back of the phone to bulge.
- If the operating envelope in very hot

Conclusion:
Returned due to heavy Temparaturanstieg when used in shell. With a pure Bumper that might look different, but my priority was on mechanical protection by a strong shelter (which is not even possible with the original Samsung QI cover.)
