HTC EVO 4G wifi antenna problem - EVO 4G Q&A, Help & Troubleshooting

Hi guys the past week I've bought HTC EVO 4G(used = no warranty).. it have the problem with wifi/bluetooth/fm radio ...
I was searching in a lot of forums and many people have this problem too but there not a specific fix, so I've opened the phone and watch for myself just to see if there's a problem with the hardware.... and I've discovered that my phone doesn't have the external antenna connector...
so I think that maybe I can fix the problem if I reemplace that part (antenna) but the problem here is that the part is not comercial.
so searching and searching I've discovered that this antenna is like that the phones have (it's a external connector but I've read if this connector get damaged the signal reception will fail) ... so maybe I can take from a old phone and remplace. or maybe do a bridge with other antenna on the phone(evo has about 6 on the mobo) like antena of gps. but really I don't know if this connector has especifications or if later this mod will give me problems.
Really I want to know if this is the problem... I thought that xda-developers is the place for my question get cleared.
ote: this is not software problem, because I have done: wipes, restores, rom(RUU too), kernals, radios... but no luck
other thing is that sometimes (randomly) the bluetooth/wifi turn on but the bluetooth doesn't scan and the wifi shows "unable to scan networks".
now logcat just shows "wifi driver load error end 2" (obviously there's more log about it)
this is the image of what I'm talking about (is not my pic but is edited)

Thanks

wow
i wish there was a fix, mine comes on but the fone has to be like 3 feet at max from the bluetooth device. and with wifi. the phone has to be in the same room as the router.im suprised xda doesnt have the answer. so many people have this issue

Problem with Skype

Has anyone been using Skype lately on their Qtek 9090? I'm having a problem using it. When I make a Skypeout call it will suddenly hang up the call, and although the Qtek says the Wifi connection is still active I can no longer access the internet on it. If I close down the wifi connection then try to reconnect it can't do it anymore, I get no connection at all unless I soft reset and then it connects fine.
Anyone know if there is any kind of problem with wifi on the qtek 9090?
Thanks,
Dimitri
I have your problem
Yay, finally someone suffering the same issues as I do!! I have this on an XDA IIs which is based on the same HTC Blue Angel as your 9090.
Have you tried skype what stood next to your AP? In my case I dont get the problem with max signal, but with anything less it shows its self.
Not alot of help of course, if you have to stand next to the AP you might as well sit at a PC and use that version!
Have a look at:
http://forum.skype.com/bb/viewtopic.php?t=12511&sid=c7678729e0141ce3db97a475731b419a
And please add a 'me too' comment to the end of said message. The skype devs pick up stuff from their forum and 2 people with the same issue might mean they fix it.
To be honest, since skype hangup kills wifi for *any* application (soft reset required), it is likely microsoft's fault - skype is simply uncovering a bug in MS's software. Put simply, no app, no matter how badly behaved should be able to take out your internet connection. I have a suspicion that this problem is initiated by some kind of malformed packet. I have seen the same problem with bluetooth. I think it takes out the IP stack, rather than just yr wifi.
Anyway, here's hoping for a fix...

Hi veletron,
I saw your reply just after writing a post on the Skype forums. I'm sure what you think is wring is pretty right but I'm really hoping that it's a Skype problem as I don't see any fixes for the problems that exists with the Blue Angel being forthcoming.
After reading your post on the Skype forums I realised that I had already had a full conversation using skype when I was sitting at my desk but as soon as I try to get more comfortable futher away they cut out. What's strange is that even when I'm next to my AP, I don't see any difference in the signal bar.

Hi
WiFi reception on the blue angel is known to be sh1te. I wish they had included a dell style bluetooth/wifi antenna on the top!
I played around with some units in PC world, alongside mine. They were getting a much better signal from the BTopenzone AP than my XDA did.
The other HTC devices saw several updates during their lifetimes, hopefully the blue angel will get fixed. I have so far encountered about 25 bugs, some of which are pretty serious ones.

Intermittent GPS Problem

Hi there.
I've searched for this problem and hadn't found much information, maybe some of you had this problem.
The problem is: The GPS software don't receive signal from the GPS receiver, sometimes 1 (to a max of 3 bars) on the satelitte options of the GPS software go up, but no fix. Other times with no apparent reason it works correctly until it goes out again (from some minutes to some days).
I've tried with this softwares, and the same results:
Tom Tom navigator 7
Garmin XT
Ndrive (don't know the version)
and
NoniGPSPlot (it's not a navitation software but should work to test)
I've tried several ROMs, same results.
I've tried to clean the internal antenna contacts and bend them in a way to make a best contact.
Any guess?
Best Regards.
Have you tried updating the quickgps to get a better fix?
Also where are you running the gps from? (home, outside etc.)
Hi, thanks for your reply.
I've tried that, but I think it wouldn't make wonders anyway. One of the times I was able to put it working, was after updating QuickGPS, but now I see it was a coincidence.
I make most of the tries at a balcony I have in my apartment where I can see about 70% of the sky (it already worked there before).
Any more guesses?
Best Regards.

Depending on the location, i have realised you have to move around to get a good fix.
If you move around, say around 2 square meter in you balcony you wont be able to get a precise fix as the satellite will think your are still in the same place. Try walking around with it on the road and see if you get any improvements.
if you still have no luck and since you have tried various roms i would suggest you send it for repair?
I thought that it would be better to be still to get a better fix... It seems I'm wrong.
I'm now trying the original ROM from HTC.
BTW, "as the satellite will think your are still in the same place", I thought the GPS system only receives information from the satellites, am I wrong?
Best Regards.
Sorry i meant the gps reciever
Finally I solved the problem.
Sent my Artemis to service
The main board was replaced, now it works as a charm.
Best Regards.

GPS Problem - all of a sudden it won't fix

Hi all,
I have some sort of problem with the GPS. Last Saturday it suddenly wouldn't get a fix at all. I tried taking the battery out and rebooting and still no joy. Then suddenly on Monday it started working again. I was on a flight on Wednesday and it worked on the flight too. About 2 hours later, I was on a train and again, no joy but put it down to maybe some strange coating on the glass. However, I tried again yesterday while out in my car and not a dickybird.
It sounds like a loose connection in the phone or something like this. Does anyone have any photos of where the GPS unit is or how to dis-assemble it to check the firmness of the connection ? Or is there any program that I can load on my TP2 to check what the GPS is actually doing ?

Having the same sort of issue with GPS on WM6.5... HTC are (well should be) working on but they have so far sent a gps test cab in the last month... which was useless... like you it will work great one minute then 'acquiring satellites' for ages... unless you have dropped and damaged radio would put the tools away for the moment as looks like software related (how WM6.5 manages GPS lock) that is the problem
I've never had a problem before and i've used it both at home and abroad. I'd use it a couple of times every week.

People have said upgrading the radio helped or used the GPS hotfix from HTC... Did this myself recently and must admit it seemed to fix the problem...
I'm running Energy ROM 23557 Sense 2.5 Maxmanilla.

Thought the GPS hotfix on HTC site was for 6.1... so it works on 6.5 as well?...was going to flash the lastest europe 6.5 (with sense 2.5) it has a later radio but have read messaging is slow for some people, as waiting for HTC to fix on Telstra 6.5 is painful

When you say you can't get a lock, is this in just one particular app, or have you tried multiple GPS-enabled apps? You may need to determine if the device actually isn't seeing any sats, or if your app just isn't playing nice with the com port anymore.
THIS LINK is for Chartcross' GPS Test (free), it can at least tell you if your hardware is getting a lock independent of any nav apps.
Excellent - exactly what I was looking for. I'll test the Chartcross software on the way home tonight.

OK, I've got a Yellow circle and it says "GPS Starting up" so obviously doesn't even start to pull down data
Any ideas on what I can do ? Could there be a loose connection somewhere inside the phone ?

Did you see it scan through the com ports when it started up? The next thing I would check is the settings (settings-all settings-system-external GPS) and see what it says on the "programs" and "access" tabs
The GPS hardware is a chip that's soldered to the motherboard, so I doubt that's come "loose"...the only other hardware connection that comes into play is the one to whatever antenna the GPS utilizes, but I honestly don't know if uses the same one as the phone/data, or if the chip itself is just a fully integrated receiver
It scanned through the ports and identified it as COM4 and set the speed to 9600. I assume the circle should go green even if the antenna was weak but would be going through the motions of acquiring data.

If it was seeing any sats, there would be bars in the screen, like the screenshot on their site...so yes it def looks like the phone isn't locking at all. Just to be sure, is your QuickGPS data up to date?
I'd say the next step to try before trying to crack your case open would be to follow ultramag's suggestion and flash to a different radio...some users report drastic improvements in GPS performance after taking that step

How long did you wait? I've noticed that it can take up to 10-15 minutes before it'll lock all of them in and turn green. Are the bars moving at all?
Was running over 30 mins and stayed yellow. Bars never budged. I've had the same radio for the past 6 months at least so can't see why it would suddenly become a problem now.
Looks like my only option might be to open it up and check the connections. Everyone drops their phones now and again and I'm no different so there's every possibility of something having come loose.
Has anyone got a photo of the inside so I know what I'm looking for ? Where is the GPS ?
C
com 4 is correct as is 9600 baud. Likely the issue is with the radio you are using. T Mobile radios seem quite touchy. Try a new radio and see what you get. Start gps test first, get the gps running and locked before opening any program that needs gps to work and you likely will have better performance.

mine was working fine and like you was doubting my hardware... seems strange as my issues started with a software update ...some telcos (Telstra in AU) software conflicts with GPS... I installed a HTC rom from Europe yesterday and GPS is now working great... even now locks while car is in garage.. the HTC Desire just released in AU is also having GPS issues on Telstra 6.5 rom ... so have you tried a rom update? as sounds like may be your issue as well...
I'm running Deepshining Rom X6. I had the previous v12RC running since it was released with no problems. I had radio 4.49.25.17 running all the time but just decided to up this to 4.49.25.77 but still no change. It still says "GPS Starting Up". I must have some sort of loose connection since it wouldn't work last Saturday or Sunday but then worked fine on Monday and Wednesday. However, it hasn't worked again since last Wednesday.

I just opened up my TP2. Is the GPS chip just to the left of the Camera ? (on the right is the Speaker)

[Q] Getting crazy with "wi-fi error"

Hello everybody.
I've read thousands of post about the matter, but can't find the solution. So here I go:
I received a used HTC Desire HD as a gift: It was an Orange UK, but as for today I managed to root and S-OFF it. I've tried several ROMs (right now I have Android Revolution HD 7.4), but the problems persists. Whenever I tried to turn on Wifi, after a few seconds it shows:
"Error"
So I'm thinking it's a hardware issue. BUT, as a last resource, I'd like to try some old ROM to see what happens (as I have read that some Orange DHD got troubled after updating). Tried on SHIPPED ROMS (Ace model), but every zip I download is faulty.
Any ideas or suggestions would be higlhy appreciated.

WIFI antenna is in battery cover.. That could be your problem!
Please check my post about covers: http://forum.xda-developers.com/showthread.php?t=2368435

Thanks! I'll check that.
However, It is very difficult for me to access to new covers, as HTC isn't very popular in my Country (Argentina).
Do you know if GPS shares antena with Wi-fi?
The manual states that Wifi and Bluetooth antena are located "behind battery cover". However, Bluetooth conection works just fine. Besides, I tried to activate both GPS and Bluetoth with the cover out of the phone, and they worked.

Well the GPS antenna is under the flash cover. I'm not sure about the Bluetooth antenna as I rarely use Bluetooth. Have you checked to see if there are any black spots on the battery cover contacts. If there is, that is the plastic showing through the gold conductive paint, and then you will have problems. Other than replacing the cover, or painting some conductive paint on the contacts, I really can't think of much else to try. Do you know anybody with the same model? Perhaps you could swap the battery covers to test. If it doesn't work after that, it may well be another hardware problem.

GPS problem

Hello everyone,
I have à problem with my gps. It's not working since i changed the motherboard Last week. I unmounted and reassemble 4 or 5 times the motherboard for see if a connector wasn't good connected but all time i see nothing bad.
I also tried different roms but it's the same
I checked with GPS test, and i have more or less 20 satellites on view, but 0 in use.
I look on internet but can't find the emplacement of this antenna. Some of you have à picture where we can see this antenna.?
I read on a forum that most of time when we change Motherboard we have this problem, had you already heard this?
And can we change this antenna? ( on internet i found Bluetooth, nfc, but not gps...)
Thanks for your help.
So i checked with my old motherboard and like most of time with this problem, it's a hardware problem. When i saw 20 satelites it was because of internet. When i booted without internet i had 0 satelites in view.
And it's mean also it's imposible to change the antenna.
Bad new for me but i have my answer.
