I ordered multiple cases for my S5 & they were delivered today, yes on a SUNDAY !!!
Some words about all of them since it might help you decide on the ONE..
1. Cruzerlite Bugdroid Circuit
Looks good & is very very light. Just Like other Cruzerlite cases & yes it has a pretty good looking Android logo on its back, both outside and inside.
2. TUDIA Ultra Slim Melody TPU Bumper Protective Case
This is also equally good & light weight as Cruzerlite, the best part of this case is the extra lining around the camera which makes sure the camera lens does not touch the surface.
3. Spigen Case Protective [Satin Silver]
Looks better, much better than both of the above, silver plastic ring around the phone gives it a different look.
The phone feels much bigger & wider, tough to both apply & remove because of plastic ring.
Let me know if you have questions. As of now I am happy with my purchase.
Will update the post in case I see any issues.
I am attaching some pics for your reference.
