Um not using a metal case isn't a way to speed up anything. If anything using a metal case is just a way to slow it down. It appears English isn't your first language but your thread title is misleading.

한국인이시군요.. 방갑습니다^^
제가 영어를 잘못해서이겠지만.. 설명을 보고 이해를 못하는 사람이 상당히 많네요..;;;
메탈케이스를 장착후와 탈찰후 다운로드 속도가 엄청나게 차이나더군요.
제가 설명하고자 하는 내용은 일반적인 메탈케이스와 알루미늄케이스를 착용했을경우 LTE다운로드 속도가 급격하게 하락했습니다.
그래서 다운로드속도와 업로드 속도에 민감한사람이라면, 되도록이면 메탈케이스와 알루미늄케이스를 구매하지않는게 좋습니다.
제가 테스트해본케이스는 총두가지입니다.
하나는 일반적인 금속형케이스와 실리콘형케이스. 대신 두개다 두꺼운케이스입니다.
일단 모든 케이스를 탈찰했을경우
다운로드속도가 20회실행했을시
MI9와 MJ7 의 다운로드 속도차이는 변화없음. (MI9보다 MJ7이 핑속도가 더좋음 그리고 업로드 속도약간향상)
메탈케이스를 장착했을때 LTE 다운로드속도는 20회테스트로 평균 1메가 내외로 급격하게 떨어졌습니다.
또한 실리콘케이스를 장착했을 경우와 탈착했을경우 속도는 같았습니다.
하지만 메탈케이스를 장착했을경우 다운로드 속도가 1메가내외일경우
실리콘케이스나 케이스를 장착하지않았을경우 다운로드 속도는 5~6~ 12~mb 까지 엄청나게 향샹됬습니다.
테스트횟수는 각각 20회씩 번갈아가면서 3셋트 테스트했습니다.
결론은 금속케이스는 LTE다운로드 속도에 영향을 준다입니다. 확실히 체감으로도 차이가 나는정도이네요.
단 Liquid Metal 일경우 이론상으로 전파에 영향을 주지않으므로 Liquid Metal로 제작된 케이스는 착용해도 큰 변화가 없습니다.
제가 말하고자 하는 요점은 이것입니다..ㅋ

Sure it is. You just need a couple of electrical engineers and embedded software engineers to help out.
A budget of about 1-2 Million would be nice, too.
When you are finished, though, you might want to call it something else besides an Eris - maybe something snappy like "Erris".
Maybe hire a marketing guy and a sales guy, to help recoup your losses.
Oh crap, I see where this is going...

I remember when some guy took some processor boards for SGI workstations and had them solder faster processors on them
http://forums.nekochan.net/viewtopic.php?t=1071
But the eris processor is likely more specialized.
If by "faster processor" the OP meant "better speed bin of the same (msm7600) processor", the answer is "yes, with big risks": in general small processors are not socketed, but rather surface mounted (especially for cell phones, where space is tight). So even swapping a processor which is "identical" without the right equipment is both tricky and risky too. You can find videos on the web showing people doing this - on a cell phone - using a heat gun, some aluminum foil, and a vacuum pick-up tool.
If we're talking about a different processor, it is highly unlikely that it would share the exact footprint of the msm7600 - in which case you are talking about a new circuit board design, which is close to the same thing as starting from scratch.
Short answer is "No!".
^^ =\ I read that halfway through my answer and now I wasted all that time lol
Covered.
Thanks.i might try some of that stuff once I won't need mt eris anymore

It's pretty simple. Using a standard pocket knife, shave each battery down flat to the width of the Eris battery. Line them up parallel and hot glue the two side by side (duct tape can be substituted if desired). Cut open a 1' section of 14/2 AWG wire purchased from Lowes or Home Depot and use the ground wire to wrap around the now affixed batteries (very important to use ground wire as we don't want anyone getting shocked). Hot glue or duct tape to make a permanent bond and your finished. Oh, and dont forget to wipe battery stats before starting.
It's a good idea to have the phone plugged in the first time you boot. For increased affects, hold the phone over the toilet.

I've ripped it apart a few times, no fin, but there is enough clearance to do so, I might give that a shot just because.
Not sure of the potential interference to cell signal though..
Good idea regardless, even aluminum foil at that close proximity with maybe thermal compound or a pad would do more than nothing, in theory.

(edit - all that tape covers areas i didn't want to short, antenna connections mostly. )
View attachment 2220069
So I actually went for it. This is 8 layers of aluminum foil stacked, by folding on of the precut sheets on top of itself until it almost exactly matched the internal dimensions of the LGOG.
This picture is slightly dated, The red+blue borderd box indicates more material I had removed and is no longer present in the rear cover of the phone. The WiFi antenna is located in the backplate for our phone, I thought it wouldn't be affected by the foil but there were two seperate issues.
1.) The contacts themselves didn't always make contact, effectively leaving no antenna.
2.) wireless signal sucked
Also, directly under that area on the opposide side of our mainboard is the LTE antenna. Again *should* is the key work that in theory it would run with no issues, able to radiate out the front of the device.
1.) LTE signal was dramatically impacted. Disabling LTE and using 4g showed fantastic signal. So if you don't use LTE or have LTE in your area this foil can stay, maybe increase the cutout around the contacts so WIFI antenna reattaches correctly.
Also note the cutout area on the bottom. That is our main antenna block attached to the speaker.
1.) Every part of the antenna areas has to be taped to try and use this area.
2.) Foil by itself with no thermal interface material is very unlikely to be sponging or collecting any heat at this relative distance from the hotspots anyway.
3.) Overall signal sucked, not worth it.
Take note of the two metal shims on the top and right of the battery. There is an almost entirely metal "basket" that houses every bit of our phone on the front side.
1.) This is in place to transfer some of the heat that the foil picks up from the transceiver module (metallic thing that is NOT taped over above the top right corner of the battery)
2.) This yeilds a very nice increase in thermal "density" overall. It is a much increased area over which has to heat to reach thermal equilibrium.
In the end I've been running this for about a week now. Placebo effect over and done, testing here and there and I can report.
It makes a dramatic impact on overall temperature regulation of the phone. It does not completely eliminate the hotspot on the back but it does spread it very effectively.
The phone can still reach "thermal saturation" as it were, and will given enough time. There is a weird tradeoff now involved, and I'd have to go back and test this separate to draw any definite conclusions, thusly;
1. You now have more material that can eventually heat up to the point where the phone throttles, this naturally takes much longer to occur (which is good)
however, in theory, this added material still has to find a way to radiate its heat, which might take LONGER to do so.
However, however: ..You also have a greatly increased the surface area that this material can dissipate heat over, so it could take LESS time.
Needs to be tested, but subjectively I can say it is better overall.
Most dramatic increases I get for my personal use case that made this worth it,
repeated restarts from multiple flashes and validating startup tweaks, voltage settings, governer advanced settings properly all taking and setting, etc. Much cooler overall, verified by constantly checking CPU and Battery temps during and after.
Running the phone on LTE, with bluetooth and GPS on, while actively navigating with maps, while actively streaming audio to my car stereo via bluetooth, while hooked up to car charger.
Does NOT hit the point where the screen is impossibly dim and refuses to charge because of how hot the phone gets doing this.
If you've used your LGOG as navigation while docked to a stand on your dash you know exactly how hot this phone can get. It also cools itself insanely faster after this.
Ultimate tradeoff: I have slightly less signal for LTE overall, and it's very slight. I could continue customizing my cutout, and will eventually, but this is working very well for now. It's almost much cleaner than the picture indicates, as once I finalized what worked I trimmed all the edges and cutouts around the backplate fasteners, etc.
Good luck and have fun if you're feeling adventurous.

Yes to all these things, except thermal compount, not yet anyway. I wouldn't mind updating and trying to do with comparisons, but in my ADHD world right now I'm trying to get ubuntu booting under chroot on my phone to see if I can compile source, for the hell of it.
dont feel like opening my phone up at this exact moment but I will, eventually.
lol, awesome. I'm too poor to take my phone apart, but if it needs a battery replacement before 2015, I'll definitely try this out. If you could machine a solid piece of aluminum, or even better, copper, it would work even better. :good:

I remember you mentioning his on the BeanStalk thread. Didn't think you'd make a post. Well as an update for you, I go my dad to re-solder the battery connector, so it's like new i'm thinking i'll give this a try. I keep LTE off due to battery drain anyway.
You must live with spotty lte service. I get plenty of battery on lte with excellent signal strength. Your drain likely stems from frequently switching between lte and hspa

- Technically possible; Yes
- Is it beneficial; Not really
- Does it require system level tweaking; Yes
- Would someone be willing to spend hours working on this so you can lose the signal; Ask around
If you're concerned mainly with the radiation, avoid keeping it in shirt pocket and use a high quality casing that "might" reduce the effects.
You could also try an aluminum casing but it interferes with the network esp in low coverage areas.
If you really want to get off the radiation grid: use good old letters (and lose trees ) JK

I've had the Z1 and Z Ultra before and now I have a Z2 and Z2 tablet.
My current Z2 has a less than 1mm gap on the upper right corner and bottom left corner.
I noticed that the tablet also has some very tiny gaps.
Is this something to be concerned about? First I thought maybe it has to be that way and I googled about it but could only find those extreme gaps.
I guess there's no phone that is 100% fit around the whole frame.
This is pretty much just quick thread so I can stop thinking about it.
Thanks !
I strongly believe it must be like this because of extansion/extraction issue. This phone is made of glass, metal .......

There is no proof in that, it does reduce reception, but this will depend on the location and where the transmitter tower is located, where I live even with any aluminum bumper or case, I get full bar status.

You're probably on the low-range frequency, then. (850/900). That range is easily capable of penentrating reinforced concrete, aluminium isn't an issue.
Anything above that will degrade very quickly, down to the point where it will kill the 2100 frequency reception (used for 4G in most countries, 3G is usually near 1800.) even if you stand next to the tower.
If anyone thinks aluminium doesn't affect signal strength, go research Asus' blunder with the TF200. They had to replace all the casings with a plastic bar just to get WiFi to function.
And before anyone suggests just sticking to low frequencies, no. Higher the frequency, higher the data transfer speed, but also the weaker the signal.

With 3G we have 900 and 2100, 4G it's 1800 and 2600.
Since I'm not using 4G then it's. 900 and 2100, I'm using 3 different networks and only one of them supports the 900 and 2100 frequencies, the other two are 2100 only.
Hope this can determine your results.

Yeah let us know ! I dropped my note 3 a couple of times. The frame isn't in the best shape, I don't wanna look at the damaged frame and a frame replacement is hard so I do hope to find a good frame !
