Do metal cases and bumpers affect reception?

[aeronium]

Hi all,

I'm looking to get one of those metal bumpers or cases for my note 3, I was just wondering if these will affect the signal strength?

Thanks!

The bumpers shouldn't, because they only cover the sides/bezel. A metal case can potentially affect signal strength, depending on how thick it is.

I just got a metal bumper for my Galaxy S5 and there appears to be a noticeable impact on GPS performance. the GPS appears to be drifting and lagging a lot when I play Ingress which uses the gps.

I will try a couple of days without it again to verify but its really annoying cause the gold metal bumper looks really sweet.

GPS is definitely back to normal with the plastic bumper after a week of using it again.
I'll now switch back to the metal bumper for a couple of days.

I did notice worse reception and difficulty with the GPS keeping to the roads when driving with the Metal bumper, which is a shame because it looks fantastic on the phone.
I guess we are limited to plastic.
