ill give that a shot. its ****ing pissing me off

from tmobile regarding the "loose hinges":
After investigating various hinge tension settings to find the best user experience, HTC engineered the T-Mobile G2 in such a way that it can be easily opened and closed with just one finger. While this tension level may let the phone open on its own if held in an inverse position, this does not represent a defect in the hinge mechanism.
regarding the random restarts:
As for the phone randomly restarting this is a known issue and is being researched for resolution. I would need to transfer you to our Technical Care Department for further assistance.

On a side note, I OC'ed my phone using the VISIONary temp root and and I am running @ 1.42 Mhz, and this this thing is not only flying, but I no longer have reboots, or at least as frequent. I had one today, but it was after it had dropped back to 800 Mhz, and the batt was somewhere around 25%...this maybe due to the profiles I have set....as the batt dwindles down, I am gutting down on the power requirements to conserve batt.
2nd side note....my first G2 got stuck a few time on reboot on the G2 screen as you mentioned.....they replaced that one without any objections.
As for the OTA, Tech Suppoirt does not ahve any news nor knowledge that one is coming out. They actually referred me to TMONews.com to see what is developing....lol...they refered me to a blog!!! SAD!!!!

I think I figured out the random reboots with the help of some others.. here out my story. So me and my best friend both have G2's. Love the phone btw. he has never had a random reboot until this day and I allways get them. I live in a basement and he lives in a house with perfect reception. I am pretty certain it has something to do with the reception going in and out. he came over the other day and we were hanging out at my house and his phone random rebooted for the first time ever.. and I allways get them because most of the time I am down here. But when I am out and about for the day above level lol.. I never get them.. or RARELY get them. Hinges have been fine for the both of us also. Other than that I love the phone.. HOpfully with the OTA update I heard about will fix that because I hear the update includes a new radio update.. and last time the radio update REALLY Fixed my reception issues with the G1 in my basement.. SO can't wait for that. Thanx a lot for reading

Better 3G and Reception Modification.

I'm only sharing this to give those with intermittent 3G data to improve theirs as well since I had such good success with it. I know it's strange, and if you don't have any issues with your 3G signal quality than there is no purpose in trying this.
To those of you who have done the hardware GPS fix, this is very similar.
There is another metal tab on the opposite side of the phone, it looks exactly like the one you bend up for the GPS fix.
I was having very spotty and slow 3G covereage, so was my fiance. It would just hang when trying to load websites or using the XDA app. The download arrow would take FOREVER before finally lighting up and going somewhere.
So I opened the phones and bent up that other metal tab, assuming it is the antenna for the phone. I have found out, apparently, it is the WiFi contact. But strangely enough, this has had a huge impact on my 3G consistency.
DarkSandz93 said he noticed two more tabs near the bottom of the phone. You might also bend those a bit to make a better contact. I don't have any pictures of them but With some looking you should find them. I can confirm this fix works without bending the ones on the bottom, but it Wouldn't hurt to try as it will only improve the weak contacts.
When I put the phone back together me and my Fiance's phone both have great consistent 3G and reception went up a bar or two.
I've been testing this for two days and it has definitely helped!
***PLEASE BE CAREFUL WHEN BENDING UP THE TAB, IT MAY BE FRAGILE*** Take it slow, Its almost flat when you start but you need to bend it up a bit to make a good contact with the antenna.
I'm not responsible for any damage you do to your phone.
Thank you AndroidMonkey for the pic.
Labeled is both the GPS on the left and the Antenna on the right. The one on the right in the one I bent up slightly to improve the contact and get better signal.

Here is a video of my phone browsing AFTER the mod was performed. Before I could barely surf at all, it would take around 5 minutes to load ANY web page. The download arrow would hardly ever light up. These pages are not cached and are using my 3G connection.
I just want to clarify this fix did not improve my actual download speed (kb/s), but made my connection more reliable and steady. Fixed the hanging and having to reload constantly to try and get a connection.
Also, thank you Plato56, who came up with the original Hardware GPS Fix. I would not have ever tried this if it wasn't for KWKSLVR's thread.

UPDATED: I've tried this in many different areas now and it works great. No more waiting on the download arrow to light up.. kicks on and stays on

I Thought that was the wifi contact and the cell antenna was on the bottom of the phone.
In any case.. I'll prolly give this a shot since the GPS fix worked so well for me. Instead of trying to bend it up though I think Ill follow the lead of some people in the GPS thread and place a small piece of rubberband under the contact. Dont wana have to solder due to breaking the contract a second time lol.

You might be right. I wasn't 100 percent sure it was the antenna. But In any case it definitely improved my signal quality on two seperate phones.
Please let me know if this works for you!

sorry to go off topic, but is this real? - http://i305.photobucket.com/albums/nn210/imitebewrong/storm.jpg

Haha yeah that's real. I took that picture I think in 08. That storm produced a tornado that killed a few boyscouts near Omaha nebraska. I was driving to visit a friend in Omaha and I got hit with 80 mph winds while in my car! It was nuts.

I can confirm this, when i did the hardware fix i noticed 2 of the same tabs at the bottom and the one on the left that the OP is talking about so i decided to bend ALL of them up and voila getting pretty good signal ever since

haha *sigh* I guess I'll give it a go! Taking the phone apart is a real B*[email protected]# though. I'll report back when it's done

Thanks for sharing, I'll post the option of bending the other tabs in the OP. Doesn't hurt to try.

yea sounds good but don't forget to mention in big giant bold letters to take EXTREME caution so as not to snap any of the connections off, don't want anyone coming back here to ***** at everyone because they made a stupid mistake.

Haha, good point. OP updated.

man i want to try this because i don't have 3g at my place when i'm holding the phone on the bottom. I'm just scared, really scared.

Alright I just tried the hardware fix and I can report that it has not improved my 3g connection dramatically. I'm not sure if I'm under placebo effect but I think it is helping a tiny bit with keeping the connection strong; could be wrong. Report back after some more testing.

I just want to clarify this fix did not improve my actual speed, but made my connection more reliable and steady. before I could barely browse, now i can very consistently go from page to page with no hanging or having to reload many times.

yupp...so the unthinkable ,while having a very heated discussion with girlfriend on instant messenger via computer ,i broke the little copper contact ,,,,
if your as dumb as me (argueing with girlfriend )while bending the little tabs, all hope is not lost i stripped some copper wire out of a phone cord and looped it through the little hole where the copper is attached to the phone twisted it together tight snapped the phone together and did some intense browsing ,seems to be working great

Unless you're using wifi this shouldnt do anything. The tab you are bending is used for wifi only. The tab that is used for cellular is on the bottom.

I tried this, and now my phone is out of commission. Might be a coincidence since I have been doing some modem changes but any thoughts on the matter would be appreciated. I posted in the Vibrant Q&A forum:
http://forum.xda-developers.com/showthread.php?t=949089

If everything is in place inside the phone and its just the screen you can get it into odin (Plug in USB and hold volume buttons while booting.) and then flash back to stock and warranty the thing. You dont even need to see the screen to do it, your computer should tell you if the phone is connected.
My instructions suck, try these

I did this too sometime last month and saw an improvement. I decided to take it a step farther like the a couple guys did in the GPS thread did. All 4 of the contacts now have a small drop of solder on them, filed down to the right height, and I am seeing improvements across the board (nothing dramatic, but more of consistency). I need to file 1 down just a hair more though.

Dropped my HD2 and now it gets horrible reception :/

So an irresponsible night of heavy drinking and dancing led to my phone making a crashing debut on the dance floor. I lost my battery cover, and I figured that's why my reception became so horrible and couldn't get data ANYWHERE.
I got a new cover, and still I get horrible reception. SMS won't work sometimes, I drop calls like made and data is terribly slow (Edge) if it even works at all. Sometimes 3g, gprs, or hpsda (is that right?) will work but only when I'm really close to a cell tower.
Anyone know wtf i did?

Sounds like you damaged the phones radio on the inside when it hit the ground.

Yes... purely on speculation you broke one of the two brass clips that make attachment to the radio antenna on the rear case.
Nothing a quick look inside can't fix...
Good luck..

I like the sounds of that
I'll crack it open tomorrow. THX!!

WOOHOO!!!!
Turns out due to the soft case, i one of the antenna tabs was bend down. Bent it back and voila!
Thx guy! I give you internet wines, 12 internet goats, and i shall dance at your wedding!

Great to hear of your success. Glad my speculation turned out to be a validation.
Awesome

hmm, my gps stopped working a few mths ago when i dropped it, , , hope my repair goes as well as yours! (when i get around to buying a new screen)

Really Disappointed

I have recently bought a Desire Z and have to say I am hugely disappointed with it thus far. I am finding that the battery life is poor and more worryingly I am continually losing my network signal. I had an HD2 previously and had none of these problems. Just wondering if the way forward is to go down the rooting route, will this improve things. I am currently on stock rom/ radio on t-mobile UK.

Never had these problems since day one... if you got dz just recently, you should get it replaced, may be it is a defective piece of hardware which is why you are losing signals and battery won't last long enough. I never had a problem with dz/tm g2's battery or network signals even with stock rom. after i flashed different rom, battery time goes up and down but never seems to be bad.

Yeah I honestly have not had any problems with my G2. I love it. My only gripe is the loose hinge issue...I took mine apart and stretched the spring to help, but it's still a little loose. Never had any issues with connectivity or battery life.

If the only real problems are battery drain and signal loss, it could be an issue with the radio. You can certainly root it and flash a new radio to see if that helps alleviate the issues. If not then there are guides here on how to put it back to factory conditions, which I would do, and see if you can get it replaced.
Or just get it replaced first and see if the next one is any better. I haven't had any issues with mine. I got it in February of this year and this is by far the best phone I have ever owned. My fiance has an HD2 which is giving her nothing but problems (kinda the reverse of your situation).

Thanks for your replies. Wondering if there is a network issue, as my wife has an HTC Wildfire which is doing the same signal loss thing, don't know if the DZ and Wildfire have anything in common which would cause this problem? Just seems odd that we have both upgraded to HTC Android phones in the last 2weeks and both now have issues.

May be it is an issue with network? Sometimes I have strange issues with Rogers, it usually happens around same area and the same time of the day, each time it happens. I wouldn't be able to do anything with my phone during the period of time if I am in the area...
Speaking of HTC, they make a very nice piece of hardware, I have seen pictures of HTC phone saves a life of a person hit by a bullet... So far, this is my 3rd HTC phone, never am disappointed, may be you just having hardluck.

You're not suppose to stretch the springs.. compress it or get stronger ones

How do you hold you phone? The bottom half inch on the back of the phone is your antenna, and if I cover that with my hand while holding my phone my signal goes to ****. I have adapted and now hold it with my left hand thumb and index finger.

Also I have taken to putting the phone in my pocket with the screen facing my body. That way it has better signal, doesn't use battery searching for signal. Also, a good failsafe to protect your screen.

GPS Problems? Poor Reception? Accessories to Blame?

Just a heads up to anyone experiencing GPS and or reception issues, if you have any aftermarket accessories, be conscious that they may be the cause of your problems.
I've had GPS not been able to lock for a while now, and it turns out that the sole cause of this was an aftermarket metal battery cover. As soon as I put back the stock plastic one, I got a full 8 satellite lock within 20 seconds.
Any metal case, cover, bumper, etc could be having a negative impact on your reception and or GPS. This was definitely the case for my I9100

Yes! can confirm this I had the same issue a while back.

Yup, general thing.
Had the same thing happening on the HD2 just like alot of other people who bought the rubber like protection things when they just came out.
Actually it just not only blocks GPS but also wifi and mobile signal a bit which results in a bigger battery drain too.

It was quite annoying to realize that I've gotten lost a few times the past few months all due to an accessory I paid money for
Makes sense why early iPhone 4's had problems with reception, due to the metal housing

So it's just the metal cases? I've a gel case for my SGS2 and it works great with it

It's not the iPhone's fault brother, like 'he' said; "You're holding it wrong."
On a serious note, the case definitely have impact to signal and heat dissipation. Once upon a time, my HD2 was plagued by signal+heat issue due to some crappy case.

I get you cand send e-maild but sms', no. . Since I don't know where you are from, go to your local network operator store and ask someone to give you the right number for message centre. This should be stored on your SIM card but it seems to be a little problem.
