What do we have here? A discovery I made on BriefMobile.com about an extreme loss of signal while using the HTC EVO View 4G. As sad as this is, it is true. I have embedded a video I made describing and detailing this problem.
Can anyone duplicate this issue? If so, please explain in detail what is going on, and then go ahead and send you complaint to HTC and see what they have to say. I have already done so and am waiting on a reply, but if anyone else wants to join me, please send this video along with any others to HTC and mention where you found it first.

Keep the tablet in portrait mode?
I can confirm it on my View.

That's dumb...heck honeycomb can't even be used in portrait mode.
I have ordered a tpu case for mine. It is supposed to be here on Wednesday. Once I get it, I will put it on the View and see if it helps resolve the issue.

Huh? You tell him that's dumb but then you make a dumber statement? Honeycomb does work in portrait mode. The only native app I"m aware that forces landscape is Market.
(Owner of an HTC View and Acer Iconia)
I was able to reproduce the problem with the bars on mine, however it didn't really seem to cause a performance hit for the most part.also, except for one hiccup, I have stayed consistently in evdo on the 3g side since my last reset.
Also, I have the official htc case from sprint, and in the case I don't really se e the signal drop. However, in a stupid design flaw the case hinders the speakers.
just curious. why would a case make it better? wouldnt it make it worse? I see this on both the flyer and view.
Just ran speedtest in portrait mode with around 950K download and 640k upload Average over 3 runs. Land scape had a 400k average download and 300k upload. Then back to Portrait with a 950 k download and 670k upload.
It is Def a performance Hit holding it with 2 hands in landscape. Holding with 1 hand in landscap with hand supporting bottom of tablet has no effect. That is the way I use it as I'm using my other hand to navigate. Only time I use 2 hands is when typing or reading. But it is an issue, though probably won't be able to be resolved. Your hand isn't the best conductor. There Just needs to be a label like on several of my other phones that say, "Holding in this area may reduce signal strength." This really isn't a big deal and can probably be found in some sort or another in every device out there.
Yes, Placing your hand over a wireless antenae may result in reduced signal strength. This is nothing new in wireless devices.

If the issue was similar to the one on the iPhone 4 then I was hoping the tpu case would act in a similar manner as the bumper did on the iphone 4 thus improving reception.

Indeed. Antennagate was such a big deal because it was Apple making a large design mistake and was causing dropped calls. Two things we certainly don't have to worry about. Thanks to Korey for noticing the issue and bringing it to our attention.

The problem with the Iphone was Pressure, adding a case fixed the problem as there was no longer direct pressure. There is No Such Issue with the View. It is not a case problem or lack of one. Having or not having a case won't make a bit of difference. My View acts the same wether the tpu case is on or not. It is an interference problem caused by covering the Antennae with you hand. Could be a crappy antennae, but it's not the same issue Apple was having.
For instance I can place my hand over the tablet in that area without touching the tablet and the signal strength will decrease. This IS NOT an Apple Like issue.

With all the praise for the solid construction of this device I was surprised to hear mine rattle slightly when setting it down on the sofa.
Try holding your phone in your right hand and tap the top edge at the rear with your right index finger.
Does yours rattle too?
Dont have the device yet, but its not surprising to hear that. Although Samsung has done a wonderful job with utilizing space to the maximum, it is plastic after all.
Its surprising to me. A top end device like this should not rattle!
i'd bet any amount of money its the auto foxus mechanism in the cmaera lense. every phone i've owned does this when i set it down on a hard surface. my n1 which is solid does it as well.
only way to prove it is attempt to take a photo and shake the phone to simulate the rattle. while the camera turns on the auto focus mechanism, it is no longer "loose" and the rattle will briefly go away. once the photo is snapped the focus mechanism goes back to idle/loose position, so it will then rattle.
Only rattle i have is not a rattle just the noise of hitting hard plastic .Same noise on SGS1
jje
I couldn't hear anything on mine aside from the sound of my finger tapping the plastic. Could it be your back cover? It might not be fully on. I carried mine around for a few hours before realising one of the plastic clips wasn't fully in place.

I think you're right. I've done what you suggested with varying success in changing the pattern of the rattle when constantly tapping the phone whilst touching different areas of the viewfinder.
Ok, maybe this is the auto focus mechanism but is it right and if it is why does it affect some and not others?

I get the same with the back cover off. If I apply gentle pressure to the camera lens it does lessen the rattle a little.
I know we don't go round tapping our phones as a rule but I'm not happy at this.
Just checked mine and no rattle here

More than likely (as with nearly all audio / visual imperfections people find) is that some people have better eyes or ears, or a much quieter environment. Try going to downtown Tokyo and even hearing your phone, let alone a rattle. Meanwhile up in the Drakensburg mountains here, I could probably hear a stone dropping at over a kilometer away.
Less likely is that your phone has a looser camera than others - there are always imperfections in manufacturing, and you might have hit the bad end of the spectrum with the lenses being too small for the holder. If this is the case, a replacement would definitely fix it.
But more than likely it's the first case.
I appreciate what you are saying Ryan but in all honestly, I think it my case it's the second scenario.
I don't go looking for faults but I do expect a premium device with a premium price tag to feel like such. This rattle totally spoils it for me and with a few other niggling little doubts I had about the phone (mainly personal preference) this was the push I needed to prompt me to return the handset.
I won't be getting a replacement. Don't get me wrong, the phone is a very nice phone and is probably the best Android out there currently but again, personal preference and a few little niggles means it's not for me.
Great for those that have no rattle, enjoy your devices as I am sure you will.
It was fun while it lasted anyway

Sorry to hear about this 'rattle' on your unit...why not try at least another unit to see if that 'rattle' is also present there, especially if you think you might have gotten a defective unit...
You seem a bit to be quick at dismissing the device. Almost like you just waited to find a reason to get rid of it.
In any case, I hope I don't have that problem on mine.

well to me its normal since i've explicitly noticed the rattle in every phone i've owned, and learned a while back that it was the auto focus mechanism. so it all depends on your personal opinion i guess, but my hunch is that if exchanged every other one would do it as well. who knows though....

No not at all. There are a few things that I don't like about the SGS2 that had me considering returning it before I even noticed the rattle - this is just what cemented my decision to return it. As said previously though, the annoyances I have with it are down to personal preference and comparison to other devices I have owned.
I'm not in the 'business' or picking faults with something for the sake of it, regardless of brand, I just want quality when I pay a quality price and to me at least this rattle makes the whole thing feel cheap.
Remember those two important words, personal and preference!

I guess I see your point.
I was hoping it was a defective unit rather than a general problem with the SGS2 since I hadn't heard about the rattling.
If I noticed something like that on mine, I probably would be bothered too.
yes i agree too. if it's a defective unit, just exchange with another one while it's still under warranty.
just keep that in mind. there are no other devices out there that can match with SGII at this point. What is your second choice, if I may ask?

Get a gel case off Amazon or eBay for +/- $3 if your worried about the cameras , also the screen could crack if you dropped it. Better safe than sorry.

For some reason on the evo 3d, the youtube app is **** (wifi, 3g, 4g) and nothing loads very fast. So I use the browser and go to youtube. It loads instantly.
Oh and just root and install a rom that allows you to tether (Read as:ALL roms here)

Do a profile reset.I just did a speed test over 3g right now and got 1300kpbs.... I get anywhere from 1-1.8 mbps depending on where i am in Orland Park.
I also have lots of problems with the 3G, and it seems to be unique to the Evo 3D. It sorta just goes out sometimes.
" *Any way to protect the camera lens Im worried about when I put the phone on a table..."
I use the case from tpu-cases.com as it protects the camera (see pic below). FYI it also fits in the HTC Car Dock with the insert removed so for me, it works and looks great.
Wow thanks guys for all the responses really appreciate it, any one notice that if you hold the phone with your right hand the service immediately goes down to like 2 bars is that were the antenna is?, an nice case up there bro how much bulk does it add also have a pic of it on the phone if its not to much trouble
The top half of the phone contains all of the electronics while the bottom half is pretty much all battery. With how many antennas this phone has it is easy to block them, but most of the time just sliding your hand down a bit is enough to get a full signal back. 4G on the other hand... it's always temperamental unless you are lucky enough to live in an area that is completely saturated with it.
+1 for the TPU case too, I got one to hold me over until the kick stand case came out but I'll probably end up sticking with it now. If you check in the Accessories section there should be a thread in there with a bunch of info about them
I can't even put my right hand near the in a heartbeat lessens the signal bars to 2 smh anything u can do?
(getting frustrating really fast smh)
Cool thanks^^, it may be just my phone but i am tethering as we speak when i send a message the 3g logo turns invisible an I lose allvmy bars for just a sec is thus normal?
It may be dropping down to 1x to send it, I don't know why it would need to but if it treats it like a call then it has to drop 3G for a split second so it can connect.

I get .3 if I'm lucky. Luckily, 4G is pretty good around here.
Here's a pic of the back of the camera area with the tpu-cases. There's plenty of height above the cameras so that when you lay it flat on a table that it will be protected. IMO, it is as thin as your going to get and it will hold up for everyday use. It was never intended for the high impact stuff so obviously you have to go with the otterbox/Seidio Convert-type cases for drops and abuse.
BTW, I'm up on a hillside (L.A. area) notorious for bad reception but calling and 3G works great, when 4G is available it's incredibly fast on my EVO 3D. As you probably know, it's like that with all carriers, cell service will work better than others depending on where you are. If it's bad maybe you should consider asking for a Airwave/Airvana.
Hope this helps.

If there really was a serious reception issue, like excessive dropped calls and such, Id expect HTC would address the problem and either push out an update or offer to repair the phone, not just deny or say "your holding it wrong" like another company would.
I'm currently on 1.11.651.3 a message popped up saying that I should upgrade to 1.13.651.3 but im hesitant to do so as I dont know how that would affect my signal since I've heard some people say that upgrading their software messed up their signal, any insight on this?
Well it appears this is a design flaw!
When they where designing it they should have used some plastic! Using all metal backing makes the signal weak as hell!
Even if they can fix this problem idk! It would still be really weak!
For an example if you look at the ipad there is plastic for the Apple logo behind this is the wifi anttena!
Hopefully the back really is plastic and they did not overlook that problem! And it's just imperfections in the antenna!

I am pretty sure the Asus tech guys aren't totally dumb. I think they know about problems with WiFi and metal...
I guess the antenna is somewhere in the bezel. Anandtech (i think they were the ones) said that with their new unit wifi was okay, but it depends on the holding angle of the prime.
So it seems we DO have to take some comprises for having a full metal back. But I think I can life with that

Anandtech said the new unit was better, but not as good as the original Transformer in terms of WIFI.
Don't assume that ASUS is not capable of making such a stupid mistake. There have been lots of cases of top tier companies shipping out products with such design flaws, and I don't think ASUS is in the category of top tier company. I work in a fortune 500 company, and we get the first batch of a lot of laptops, and we test them before the workers get them. Sometimes I'm amazed at the lack of basic quality control when these devices first come out. It's like they ship out beta hardware.

There is not one doubt in my mind Asus wasn't aware that the WiFi was wearker than the TF101. However you have to realize unless the performance literally was unacceptable by whatever QC standards they have, they are able to pass the design, build the product, and ship it. Fact is only because a couple top tier reviewers recieved units that weren't up to the standards of the rest, they decided to handle the situation the way they did. In fact if they weren't aware of it, they probably would've let the stock stay as is, launch as normal, and say that "there are a small number of reported cases" as companies usually do.

This happened with Apple and the Iphone 4. The antenna was located in the bottom
right of the phone and signal was lost when you had your hand over it.
http://www.anandtech.com/show/5178/an-update-on-transformer-prime-battery-life-wifi-issues
"Using Ookla's Speedtest.net web app I get a consistent 34 - 37Mbps on the original Eee Pad Transformer (our actual WiFi performance tests involve downloading a file from a local server, but Speedtest was a quick and easy way to verify the problem). My original Prime review sample averaged around 0.5Mbps, while the replacement Prime got around 10Mbps - all in the same test location. Fiddling around with location I could get the replacement Prime up to 16Mbps. My test area is riddled with challenging interference so I setup a separate test area in another room. Even after buying the same Netgear WNDR4500 wireless AP that ASUS verified 31Mbps+ operation on, I wasn't able to break 16Mbps.
I have four other APs covering my house, I turned all of the radios off as a last ditch effort. Boom - 36Mbps on the Prime.
The culprit appeared to be either my 3rd gen Time Capsule or 5th gen Airport Extreme, with those radios off and using the WNDR4500 I was able to get performance competitive to the original Transformer. Here's where things get interesting. The original Transformer was made out of plastic, through which RF travels quite nicely. The Prime's metal construction makes things a bit more finicky. Indeed this is exactly what I saw, where depending on tablet and AP orientation I'd see anywhere between 10Mbps and 36Mbps downstream (average speed tended to be in the 15 - 20Mbps range). "
I also think it's a mistake to assume that other reviewers would necessarily notice this problem. Other reviewers might not have tested WIFI performance at all.

No one is doubting the performance isn't up to par with the TF101. It's obvious it's not. Again Asus was well aware and thought it would slip by well because of something called everyday use. If it wasn't noticed by other reviewers it's for a reason, they tested it under normal use circumstances and found it to be quite acceptible. I am in no way making excuses for Asus or the design but it is what it is. Anandtech however doesn't test like that and which is why they were able to find such a flaw. It's all about a matter of usage.
I'm about to dump my pre-order. This whole release date debacle pissed me off, and now if there is possible WIFI issues...it might be a bad investment. I've been asking myself if I really need a tablet anyhow, and the answer is probably not.
please dump it.. saves it for the people who want it.

I'm glad I didn't do the pre-order thing. I don't want to be first in line for this. I'll wait until it is generally available, and there has been time for reviews of retail units. Let other people be on the bleeding edge
I have not been close to cancelling my preorder up to this point but if this wifi issue is confirmed I may be tempted to buy the original TF. Especially considering they keep showing OOS open-box Transformers for $185 on a particular website we all know and love. If I see one in stock I think I will go that route until this issue is worked out.
I wish some more reviewers would do in-depth testing on this issue.

Haven't you ever seen a proper Wifi antenna? They at least as thick as your finger.
So they NEED to make it a lot thicker.
Otherwise we'll never get a proper Wifi signal.
You may better get a different device.

So it seems we DO have to take some comprises for having a full metal back. But I think I can life with that

They were dumb enough to test the Wifi after they've mass produced the thing instead of before. What makes you think otherwise?
Folks, let's tell the whole story here. What Anandtech also said:
I have four other APs covering my house, I turned all of the radios off as a last ditch effort. Boom - 36Mbps on the Prime.
The culprit appeared to be either my 3rd gen Time Capsule or 5th gen Airport Extreme, with those radios off and using the WNDR4500 I was able to get performance competitive to the original Transformer. Here's where things get interesting. The original Transformer was made out of plastic, through which RF travels quite nicely. The Prime's metal construction makes things a bit more finicky. Indeed this is exactly what I saw, where depending on tablet and AP orientation I'd see anywhere between 10Mbps and 36Mbps downstream (average speed tended to be in the 15 - 20Mbps range). Apple gets around this issue in the iPad by putting the WiFi antenna behind the plastic Apple logo, however it's not entirely clear to me where the WiFi antenna is on the Prime (I have this policy about not taking things apart until I'm done testing them).
As to why performance was lower with the Apple APs active, I'm not entirely sure. Chasing down RF interference issues can be a severe undertaking. One thing is for sure, the Prime is going to be far more finicky than its predecessor when it comes to reaching peak speeds over WiFi.

I know that the folks at Anandtech are smart people, but it seems like the reviewer conflated some things here. I don't know how much testing he did AFTER turning off the Apple AP's, but it sure seems to me like the fluctuating results he's talking about were from before he did so. Perhaps the Prime is fine in general but just had an interference issue with the Apple APs that actually resolved itself just fine once they were turned off.
Why would there be this kind of interference with the Apple APs? I have no idea, except that it would point to something in software and not hardware. But until we have someone who does a really good job of detailing precisely where a non-defective Prime has wifi issues, I'm personally writing this off to something being broken in his first unit.
True, he did say he could get it to 36Mbps "depending on tablet and AP orientation I'd see anywhere between 10Mbps and 36Mbps downstream (average speed tended to be in the 15 - 20Mbps range)"
This, along with:
ASUS feels the WiFi range does not currently meet their standards and has delayed all shipments worldwide. At the moment there is no ETA and noinformation on available quantities on the first batch.
http://forum.xda-developers.com/showthread.php?p=20155626
As a comparison, AnandTech shows the Kindle Fire's WiFi maxes at 15.2, and I couldn't get close to that in my own tests.
i posted in multiple threads my concerns about the wifi issue when the anandtech and cnet reviews came out. i've canceled my preorder at jr but will keep my adorama and bestbuy preorders for now though. all hype i had for this thing is completely gone. now i'm like whatever.
If Anandtech was able to get full WIFI speed turning off other AP's than that points more to an interoperability issue that should be correctable through firmware/driver rather than antenna/hardware design.
I can repeat these results over and over again on my Prime. A good distance from my router (through 2 indoor walls, 1 outside brick wall) I get the top 4 throughputs on Photo 1. I cannot stream video without an awful lot of buffering and everything else is slow. With some testing I found if I put that little piece of foil on the face of the tablet(Photo2) then I get the bottom four throughputs and I can stream video until the cows come home with no buffering. It seems simple and works well on my unit. And again, I can repeat the results. I've been using this for three days now and am really happy with the improvement. I'd be real interested in knowing it this affects anyone else's unit the same way. If it does let everyone know and this may be a quick and easy way to help with your WiFi without having to result in disassembling your Prime or doing an RMA.
I'm planning on painting it black and taping it the the face.
See post 99 for details of my installation.
That is quite impressive. I'm game to give this a try. How far down the back of the Prime does the aluminum foil go?
I remember the little antenna earlier model iPhone users stuck on their phones. Perhaps something like that can simply be stuck on the Prime's glass? But, in your situation, the foil going over the top and down the back may also have an influence. I'm going to see if this improves GPS, too! My wi-fi is decent, but my GPS in non-existent at this point.
Thanks for the post...

Holy Crap. I'm going to try this when I get home -- I've got a dead spot in my house where my WiFi drops off almost completely. If this works, I'm going to 1) laugh, and 2) think about all the physical damage that some people have done to their Primes in the hardware modding thread, and then 3) be sad for them, and then 4) laugh again, but bitterly.
Keeping the fingers crossed.
Next thing is foil hat!
On a serious note, quite interesting to see results.

Also, have you tried putting your prime in a portfolio-type case (like the Minisuit) with the foil on it? If so, does it still work? If so, that would be excellent, because the case would hide the foil.

Wow so cool! Even though we shouldn't have to do this lol. Brings me back to the days of my modded wifi dongle with tin foil upgrades to "borrow" my neighbors connection haha.
Damn I'm out of tin foil, I'm gonna run to the store and report back! Even though my new C2 serial get almost identical speeds in my living room in my apartment. Let's see how far I can go!
What about some copper conductive tape? A thin strip of it.
Interesting......simple yet effective, it seems
What happens to your GPS signals if you move the foil over to the left a wee bit (above the GPS antenna)?
I don't have a problem with Wifi, but I certainly do with GPS, so I'd be interested to see.

lol very cool. Looks like you are reflecting your wireless signal into your primes antenna. Forcing it down the throat so to speak
Cool Parabolic effect. Aluminum foil is great for that.
Even seems to work somewhat with anti-static bags.
WTF!!!
If this is really true then i'm even more glad i returned my unit. So for my 600€ toy to work i gotta get a 1€ foil-roll, ASUS are you kidding me?

It doesn't have to go down the back. I have it taped on now nd it goes from the top edge of the screen down. You have to move it from side to side to get the best signal. Again it does not need to go down the back, but to find the best location I originally had the foil going over the back.

Very cool PolishPoet. Yes I imagine if you had it in some sort of Parabolic shape. You could increase / direct the signal even more.
hahahah i love this.
Make a plastic frame with aluminum in it and you can clip on top of prime. Sell them and you will be rich!
It appears to block/degrade GPS signal. I'm getting 0 now instead of 2-3 by the window with the foil on. But wifi definitely improved.
Works particularly well holding a DVD in place. I guess they are super smooth and reflective so it makes sense.
Mixed result for me. 1.2MB/s with the foil then 5.8MB/s without the foil and then 6.4MB/s with the foil again.
If I use Wifi analyzer as soon as I hold a DVD in place I suddenly see about four other networks that disappear as soon as I take the DVD away. Happens every time without fail. Signal goes from ~70dB to ~55dB

What lg could have done, was put an aluminum heatsink that had a thin fin that spread to all four sides of the phone that would dissipate the heat from the center. Then again, I haven't ripped my phone apart. It may have that already.

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've humored the idea of taking the much cleaned up foil template i made out, tracing it on paper, and getting a copper shim machined to the same size and similar thickness, believe you me

Definitely gonna do this if i need to swap the battery anytime soon.
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
