[Q] Signal dropping during calls - Desire Q&A, Help & Troubleshooting

Hi guys, got a strange issue here. Whenever I dial a number the phone will ring a few times then the signal bars will jump from whatever they are on to nothing with an x and call will fail. However; the phone will still be ringing on the other persons end, and if I redial then it will jump into the call I tried to make previously. The same could happen again during the call. Strangely, this only seems to happen when I bring the phone up to my ear, if I use hands-free it only happens 1 time out of 10. Anyone have any ideas?
I'm using SuperNova Xtreme ROM, any more info needed?

Same peoblem here with stock... Heard it's a bug with proximity sensor. Does your phone drop the signal when you lock the screen?

Unfortunately, I have also read that there is no fix for that bad luck for us, I guess

Well, I've just done a quick Google and found that sometimes simply taking the back off the phone and hoovering everything out can help, as well as blowing/hoovering on the line between the earpiece and the screen. I'll try it out and post my findings.

Hey, I've managed to fix it, but only by flashing with an entirely new ROM/RUU. It's the only thing I could find to fix the issue.

This is a long shot, but is your Wifi and BT turned on when you are checking for the MAC addresses?
If its off, it will show as unknown/unavailable in Settings/About Phone Menu.

My previous rom was stock android (sense) on a Bell HTC desire Z.
Any ideas at all? I'm thinking I'm going to rewrite my bcm4329.ko with someone else;s if I can find a copy. Maybe they'll fix my wifi. Found out that in the logcat it wasn't loading the WiFi drivers.
I am currently having the same issue with a Desire... tried everything apart from unrooting... there has to be a fix for this!
Has anybody figured a solution for this? I am currently having the same issue. Cm7 nightly 171
It first appeared 2 days ago on cm 7 nightly 168. I have done a superwipe, reinstalled radio and all that good stuff.
same issue
I got the same issue. Any one has solved it?
Go to your home screen, turn on Bluetooth, wait 4-5 seconds, and get to Settings and check it again

Cm7 blank screen and no response

Hi all,
I tried cm7 and switched to leedroid because I had problems with answering and making calls (black screen when phone rings, no way to interact with it).
Anyone else had this issue and knows how to solve it?
It's Bravo device.
Cheers,
J.

Do you control the cpu speed in any way?
If yes make sure you have at least 245Mhz when screen is off.
Sent from my HTC Desire using XDA Premium App
No, I do not...unless CM guys coded it in their ROM. This problem happens on plain installation without any tweaking afterward.
Anyone? Come one guys!
Are you in CM7 Hboot ?

Did u do a full wipe before flashing cm7? Did u install the recommended radio for cm7?

Nope, Brovo sense Hboot.
Everything else works perfect...only wnen receiving calls and sometimes when making calls screen goes blank, notification bar visible but not responsive, buttons lit, but unresponsive. All of that for 30 sec or so...
Both when receiving a call or when making one this behavior is completelly random as I could have figured it out.

Yes and Yes
Followed the instructions by CM team. Also, as mentioned in previous post, this behavior is random. 10% of outgoing calls and 40% in incoming calls. Another thing: happens only when locked, or when locked during calls by proximity sensor.

In that case do you use a screenprotector?

I have the black screen issue. Just done a full reflash again. I get the black screen on a lot apps actually but its very random.
I think it might be due to s2e app that is used for ext3 partition.
Black screen
Ive been getting this alot lately too. My phone rings and it shows who calling but no sliders, or completely black screen with just notification bar. If I swipe where it would be though it still answers. Also when im in settings nothing but the notification bar, but if I tap the screen it brings up what ever option would have been there. getting kind of annoying.

Few connection issues with my brand new Desire

Hi there,
Ive got a problem. My brand new Desire shows 2-3 bars of network but i cannot make calls sometimes. Text messages come like sometimes up to 3-4 hours LATE. Its frustrating. Changing Network mode didnt help. Restoring factory default setting didnt help neither. What can i do ? sometimes it works but mosty it doesnt ...
Ahh and very often when i try to send a text message i get "Unable to send text mesage...." Its like it shows i got network but i havnt :/
Please help,
Thanks
I assume your Desire is completely stock? If so, might be a service provider issue rather than a software/hardware issue

[Q] No sensors working after reboot.

Hi, Im currently on the stock JB with a CID 001. My problem is that once I flash a rom none of my sensors work, after a few times holding the power button for a reboot they will start to work again. Im able to calibrate the G sensor in settings while they work but if I turn off my phone they will stop working.
This started happening after I updated to JB, I have tried using ARHD and Maximus with no difference. Each time I flash a rom they work but after they phone turns off they stop working, not just a few its all of them.
Any suiggestions please?
Just in the middle of updating my hboot to 1.39 so hopefully this helps
EDIT: after re flashing with maXimus 11 and hboot 1.39 the sensors didn't work. I restarted the phone holding the power button but that didn't help, done it again only holding the up button when the htc screen appearing when rebooting.
Any suggestions would be greatly appreciated. Thanks
Also im going to install the two OTA updates here and see if the sensors will still work after these.
Installed the first update and the sensors stopped working and then installed the second and they started working again. I think once I turn off the phone I won't be able to get them to work again. Sorry about all the posts but I'm trying to give as much information as possible.

My phone ran out of battery there for the first time since I flashed the rom so was the first time the phone has been rebooted since the updates. Now the sensors have stopped working again. I have tried rebooting several times, Killing all tasks using the task manager then rebooting but nothing. The only way to get them going again is to re flash the rom. Any help please?

I lost my gyro/compass/orientation at one point a few months ago... I tried several full wipes and different ROMs, nothing changed. However, what did fix 'em was when I relocked and flashed a stock O2 RUU to return it via my operator. Its been fine since.
So your saying the only thing to do is to send the phone back to O2 for a replacement? I opened my phone so I take it that's my warranty void anyways? But suppose I could always try. Thanks, also just compared my loud speaker to my brother phone and mine is awful compared to his

So after booting the phone into recovery and wiping the two caches and fixing permissions I was able to get the proximity sensor working after two reboots but after another it stopped working again. Any idea's?

No, sorry - I didn't send it back to O2, I flashed the RUU with the intent of doing so and that's what fixed it! Sorry for being confusing!
System problem,don't mention that.Flash another rom .That will be fixed.

If flashing an actual o2 RUU didn't work (I was a bit confused by your previous posts as you can't flash an unbranded RUU on a branded handset...) If that didn't work then its a hardware fault. Or at least a software fault that can't be fixed without the software they use in an hTC service centre.
My phone isn't branded but I got it of O2. I might just re lock it and send it back as I don't seem to be getting anywhere with this. Thanks for all your help but.

So after I rebooted my phone tonight all my sensors have started to work. I don't know what's happening here at all and I don't want to reboot or let my battery die incase they stop working again. I also noticed compared to my brothers one x his screen is alot brighter than mine?
Sent from my HTC One X using xda app-developers app
So I flashed the stock RUU and sent it away for repair and they just sent it back saying there was physical damage, Im assuming this is just that I have opened the phone. So there still isnt any sensors working, any ideas please?
I am experiencing the same problem with the sensors... still didnt find a permanent solution. I rebooted like 100 times, eventually they worked, then after a reboot they didnt.
I came across this topic, maybe it will help

[Q] Wifi not working with 2g Network Sim

Dear Experts out there
I also have HTC One VX - I don't live in US therefore I had to sim unlock the device, which I did.
I was able to successfully S-Off the device and changed the Super CID to 22222222 and flash CWM Recovery.
Everything works fine except the wifi on my 2G network Sim.
Note: Wifi works without sim, wifi works with AT&T sim but wifi does not works with my country network sim. Only 2g network is available in my country.
Workaround: I use AT&T sim for wifi to work and quickly swap it with my Network SIM and wifi works until the phone is switched off or restarted.
I need permanent solution for this if anyone can help or know what is the reason behind wifi not working with my 2G based Network Sim

This sounds odd. Are you running a stock ROM or custom? And would you be able to pull a log for us?
Using custom rom, tried many roms same response, what logs u want me to pull

Sorry, a logcat. Just download catlog from the market. Make sure to reproduce the problem. Then go into catlog, press the menu button, and hit save. Then upload here so we can have a look.

I have but I'm not quite sure what it is associated with. Trying to do some research on the subject. For now, do a nandroid backup and try flashing a different ROM if you haven't tried already to see if it helps.

This is what I found odd:
Unable to open connection to supplicant on "wlan0":No such file or directory, retry 0
I want to say it has something to do with the WiFi driver? Which has something to do with the kernel I believe? Don't know too much about low low level things.
