Aluminium case and loss of reception

Hi,
Does any one else have an aluminium case?
Do you have any loss of reception?
I seem to loose 2 bars, and have trouble switching between 3G and HSDPA, does anyone else have these problems?
I choose this case because I needed something strong and otterbox hadn't made one yet.
Thanks all

could be. all walls surrounding your device will limit the working of it...

Simple laws of physics - metal blocks radio waves.

I had a PDair case on my past phone (HTC S740) and yes, signal strength did take a hit.
Normally this was not an issue but in areas of weak signal it sometimes made the difference between 1 bar and none.
Of course if you wrap your phone in metal, it can only be expected.

Antenna Difference - Stock Battery Cover vs. Extended Battery Cover

I just picked up the extended battery, for my Thunderbolt.
The extended battery cover clearly has a huge LTE antenna.
The antenna, on my stock cover is very small.
Can any one else confirm?

That's the secondary. The main one is by the kickstand.

Why would the stock cover, have a non existent extended antenna?
I would think they would both have the same one.

forgive me if im wrong because im no expert but i think the metal things you see sticking out are just the contacts for the antenna. the actual antenna is hidden under that black electrical tape looking thing running around the edge. with that said we cant really see how big the antenna is under that black tape thing.. we dont know if they are both the same size. just cuz that tape is thicker doesnt mean the antenna is bigger...

You are right. I am assuming that there is an antenna under that tape.
On the stock battery cover, there is not even any tape at all.

I want to order this but the reports of the batt cover not having same antennas has me a little worried. Also anyone know a good seido case like the platinum one that fits this ?

According to the fcc website the antenna by the kickstand is for 1x voice only. The 3g and LTE antenna are where the two tiny holes in the cover are, and the gps antenna is the piece of "tape" that u see in the stock cover. A buddy of mine ripped his stock cover apart and it appears that the 3g and LTE antennas are molded underneath the plastic with some sort of conductive spray at the factory, that's why the very small contact point that's visible looks like the only antenna. I'll try to get a pic of the torn apart cover.

What's the link to the site you obtained this information?

On the stock cover, the antenna is on the outside, hence the two feedthrough holes. It looks like it's on the inside of the extended battery cover.

I actually experienced a little better reception with the extended battery door.
It wasn't much, but I did pick up 4G in a few more fringe areas than before.

Why Certain Cases Of Case Mate And Otterbox Degrade Wi-Fi Signal?

I ordered Case Mate Tough for my smartphone and signal degrades by 5 to 10 dBm (2 bars) when in this case. Many people reported such problem and what is interesting, it does not happen with every HTC smartphone.
One person reported that the smartphones this happens with have software or firmware issue/glitch and that HTC are aware of it and working on a fix.
Does somebody here have Wi-Fi signal issues with Case Mate or Otterbox or even other brands' cases?

I do have a case-mate barely there for my DS but not noticed any drop off in anything. Used a case-mate pop (at least i think thats what they're called) for my DHD and wifi dropped by around 50%. My worst one is with a cheapo silicone off feebay. My wifi signal goes so low it disconnects. Take off the case and its full. Annoys the hell out of me but then i prefer any phone without a case anyway so dont mind taking it off just wish i didnt have to put it back on again!

i'm use otterbox for my DS, and didn't face this problem...

I use a rubber case, and yes, the signal for both WIFI and the network drops. I think the reason behind this is that the only parts of the phone which can act as an antenna are the soft rubber parts, as the phone is unibody. WIFI signal has the worst drop though, and sometimes I cannot get a signal at all.

What do you mean by "network drops"? Cellular signal?
I have only problem with Wi-Fi signal. I have noticed that when i move away only top half of silicone, signal improves a lot. I have spotted 2 holes on top - left and right (looking from back). When i cover left, right or both with finger or silicone, signal drops, but silicone has 2 appropriate holes that allow signal to pass through which don't work right.

Hi, I don't know if my point is relevant to this post. If you hold the top part of the phone, the signal will degrade. It is true for my phone and I don't have a casing.

Your point is relevant, this is why i don't hold phone by the top when using internet.
Hold top = degrade/lose Wi-Fi
Hold bottom = degrade cellular signal

wow, HTC didnt think through the DS very well did they
Im not certain but i dont think my cell signal has ever degraded as a result of holding (always hold the bottom of the phone) but im not certain, but my wifi signal definately degrades when i hold at the top or put a silicone case on. It was only a dirt cheap case from feebay but im looking for another that wont degrade it, any recommendations?

Same behaviour for me.

Something tells me that degradation of Wi-Fi is a cost for using silicone/cases. For some yes, for some no.

i got a silicone tpu 2$ case, and the signal drops 5dbm

[Q] G2x Battery Door

Why this phone ever came out with this brownish battery door is beyond me. The O2x came out with a black battery door and it looks so much better. Short of tracking down an O2x battery door, are there any places to buy a different battery door? I've googled but to no avail.

You can paint it. Do some looking around you can find a lot of people that have done this and looks great.

Dont bother me. Im always looking at the front.

The metal strip on the battery door is the GPS antenna. There are some hidden connections on the side of the door to feed the signal from the metal strip. I would advise against painting it or using a non OEM door. When I had an extended battery with all plastic door my GPS could no longer get a signal. Many phones have hidden metal in the plastic backs that are used for the GPS antenna.

I'm using my 3500 mah battery with an all plastic door and I still get GPS locks, same as when I used my OEM door.

Thanks for the tip on back cover metal strip as a GPS antenna.
With the OEM back cover, I can get quicker GPS locks (2 mins from a fresh reboot). Using miui-1028 from siulmagic, and changed NTP server address to north-america.pool.ntp.org.
After an initial lock from a reboot, no gps locking needed anymore.
Did this test via reboot twice from the same spot, window sill. Same behavior.
Again, thanks for the tip.

Where did you hear this? I'm pretty sure the metal on the back is just for aesthetics.

I don't think this is correct, I could be wrong.. But what most have done is to remove the google strip and the cam glass (carefully) paint it, let it dry, then replace the aforementioned items.

Battery cover does not have a gps antenna in it. That would require that each door had been tuned at the factory or some expensive tuner were included in the phone. Not size or cost effective.
Gps antenna's in mobile devices are SMALL.

I like the back it blends so it doesnt brother me. But i did put a silicone case on i because i didnt want it to here messed up buy wear and tear, scratch up or damage from a small drop.

Aluminum back plate

I just w the aluminum back plates. If I buy the qi sticker, would wireless charging work through the aluminum back?

I'd be more concerned with getting a useable mobile signal with the aluminum back...

Mate, Do a search on net for this topic.
I saw numerous posts and you tube vids where people showed they went from 4-5 bars signal strength to 1-2 in same place when putting an Al back plate on their phones. I hate to think what call clarity or connection stability would be like with that low a network connection.
Those back plates may look great but they cause major problems like this.
Here is one-
http://jetcityninja.wordpress.com/2...-cases-will-affect-cellphone-signal-strength/
the new iphone 6 that all the fan boys leaped over has a metal unibody design in which there are those white plastic inserts at each end of the case, that is to allow transmissions thru the case.
You will notice the Note 4 has 4 plastic inserts thru the metal edge frame too, can be seen on chamfered edges, the rest of each one is covered by the paint on edge. That breaks up the metal of the frame and prevents it forming an unbroken loop that can also interfere with the signal pattern.

Exactly, so the back cover would really have no effect on signal because of this reason.... Right?

Buy it and see but don't say you weren't warned

The answer is no.

As I said above a solid back plate WILL most likely cause significant loss of signal strength as many have reported in the you tube clips I mentioned in my previous post.
