No sound, no sync

Hello,
If there is a thread about this subject, please direct me to it because I couldn't find it.
I have an XDA Cosmo running on WM6.1 (ricky's)
All was reasonably fine untill this sunday. All of a sudden it doesn't make any sound anymore and there is the headphone symbol displayed at the top. When I plug in a headphone, I can hear to that offcourse.
It is also very hard to sync it with my computer. I have to try dozen's of times.
I'm guessing that there is something wrong with the connector. Do you have any suggestions?
The strangest thing is that when I reboot my phone, it doesn't occur untill i plug something into the mini-usb connector.
Another strange thing was that it changed the colour of the homescreen automaticly overnight. I don't think the two problems are related, so any suggestions for this one?

yesterday, completely out of the blue, my phone had the speakerphone all the time on. I couldn't get it normal again. Then, later that day, the headphone symbol reappeared, so I couldn't make a call anymore.
When I connect it to my computer today, it keeps on switching between connected and not-connected for 2 minutes and then decides to be not connected. Even when I leave the room and there are no noticeable vibrations that could cause a bad connection.
Anyone has an idea? Because the phone is useless right now and I can't flash another rom when I can't connect it to my computer.
Greetings and thanks a lot for any piece of information.

turn off bluetooth

Bluetooth hasn't been on the last couple of months, so I don't think that that is the problem

[Q] DHD screen turns on with no reason

Hello all,
Since this morning I have a problem with my DHD. When I turn off the screen, it is supposed to stay of until I turn it on again. Since this morning it starts turning itself on over and over again. Everytime I turn off the screen, it switches on in a few seconds. But once it's on it doesn't go off by itself. So I doubt if it is a problem with the on/off switch. What else could it be?
Edit:
This seems not to happen when the phone is connected with an USB cable. Either on my PC or on the regular power charger.

Have you installed anything new at all. Also have you restarted the phone since it began exhibiting this behaviour. Make sure it's a proper restart aswell by turning off fastboot i settings, it's under power settings I believe.

Thanks for your fast reply.
I have not installed anything new since two days ago. And the problem really started this morning. So I guess it is not caused by a program I installed a couple of days ago.
I have indeed restarted my phone. Also turned it off, toke the battery out and waited a couple of minutes (just to make sure it was really really really turned off) but this did not solve the problem.
The thing I find very weird is that it does not happen when the phone is attached to USB...

Maybe USB debugging, or possibly a short on the mini USB connector. What firmware do you have on the phone?

Android 2.3.3
HTC Sense 2.1
I also think it might have something to do with a short in the micro USB connector. Have cleaned when the phone was of. Seems to have solved the problem, but that's only for the past few minutes...

Hopefully, that's the problem solved.

Darn! The problem still isn't gone. It appears to be less frequent than an hour ago, but the screen still turns on every couple of minutes

This is happening to me as well. The phone screen keeps coming on and then going off after a bit. This and randomly going into car mode and whenever I make or receive calls, the phone speaker is switched on automatically.

Indeed! I just noticed that too. I received a call and my speaker was turned on without me turning it on manual..
Update: my phone stopped switching its screen on automatically, but the problem with the speaker still is not gone.

My DHD has started showing both of these symptoms, ie, switching itself on from standby and the speaker phone being activated on incoming calls .. ever since I upgraded to Android 2.3. I'm not sure if this is something to do with 2.3, the DHD or T-Mobile (my provider) .. or a combination of all 3.
And an app called Car Panel keeps launching ..

I have this problem, too.
Before the last update of my DHD the backlight turns on in standby for some milliseconds. I saw only a short flash in standby.
After my update to version 2.3 this happens everey 7 minutes.
And the backlight is on for about 10 seconds, then turns off for the next 7 minutes.

DHD light off on
I had the same problem going to settings/dock and turning off auto launch and then power setting turning off fast boot appears to work so far

Bluetooth stops working intermittently

I just got my Sprint GN a few weeks ago, and love using the bluetooth to connect to my car audio, but every 3rd or 4th time I get into my car I notice the bluetooth doesn't pair, so I take out my phone and look and the bluetooth icon is gray (instead of blue, indicating it has connected), I toggle the bluetooth off, and then when I try to turn the bluetooth radio back on it just sits there saying "bluetooth is turning on...". Bluetooth stops working until I reboot my phone
Does anyone have any incites into this or anyone else experiencing this?

I have the same issue. It's no solution but you can enable/disable Flightmode to get Bluetooth up and running again (but quicker then reboot).

I'll give that a try (again) next time.. I am 100% certain I had tried that, though, unfortunately.

Yeah, I tried your solution again, and it just keeps saying "bluetooth is turning on..." even after I've turned *on* airplane mode.

Need some more information to be able to help you properly >_>
Stock ROM or Custom?
Rooted/Unrooted?
Or alternatively (Because it sounds like you're running a stock Galaxy Nexus...) ave you tried unpairing, and the repairing the devices?

Hi Zach,
Completely stock & unrooted (so far)
I actually did a complete factory reset a couple days ago, and the problem has yet to resurface, so I'm crossing my fingers and hoping it's gone, but the issue was intermittent so there is no way to be completely sure it won't show up again.
If it does, I'll try your suggestion, thanks

[Q] Bluetooth Won't Turn On

When I try to turn on bluetooth, the icon and text indicates that the system is trying to turn it on. However, it never actually turns on and after a few minutes reverts to indicating that BT is shut off. This problem used to occur sporadically and sometimes seemed to be cured by rebooting. However it is now at the point that it just won't turn on no matter what. I did the requisite googling and found nothing very definitive. It looks like I may have to do an exchange on the unit but I would rather not go to the effort of unrooting this unit and rooting the replacement.
Any suggestions of things to try beyond what I have indicated above?

Are you using an experimental ROM or stock rooted?

Jedi Mind Trick XI (although the problem has been growing worse and has happened across the last several JMT versions). I will give a stock rooted ICS a try.

I just tried a stock rom and the problem persisted.

I have the same problem
I have scoured the net looking for an answer, any answer, to this problem. It seems that a few people are having the same issue. But before it is ever answered, some dip$#!t always jumps in and says "I have the same problem, my phone won't connect to my car." Then the conversation goes off into other people that can't connect their bluetooth to their car or their headset- or their cat... That is not the same problem!!!
I cannot turn my bluetooth on unless I soft reset the phone. Even after I've gotten the bluetooth working, if I restart my phone the bluetooth turns off and when you try to turn it on, it says "Turning on Bluetooth..." It cycles for about a minute and a half and then goes back to "To see devices, turn on Bluetooth."
I bought this phone on Amazon for what appeared (at the time) to be a reasonable price. Since then, I believe that I have read at least one of the seller's post about bluetooth not coming on (no proof, just an educated guess). The seller probably got rid of the phone because noone could or would give an answer to this problem. Heck, it's possible that every post that I've read so far is by someone who owned this phone at one point or another. :silly:
I am sending this post to XDA because even the adminstrators on android forums say that you guys are the smartest and most responsive forum available. (Okay, they didn't say smartest- it was implied). Please help me resolve this issue.
I rooted this phone the moment that I pulled it out of the box. In other words, I don't know if the bluetooth issue is caused by the root, or if the previous owner didn't root the phone and also couldn't get the bluetooth to work. I believe that, because the phone is rooted, I should be able to remove and reinstall the app that bluetooth is based upon.
I am not a techie, the only reason I know anything about root is because I was complaining to someone about my old phone and how all of the bloatware that seems to constantly run eventually kills my battery. He told me about rooting, and it was easy enough - the rest is history. In other words, if you ask me for more information- I promise that I can give it to you. Yet, have patience with me if I ask you a question that you believe that any person that has rooted their phone should know.
I really hope that you guys can help me without bricking my phone. I truly appreciate any suggestions or thoughts on this matter.

I may have figured out what is going on, although I can't understand why it is (maybe someone more versed with processes can help me figure this out).
Using Titanium Backup, I first froze the two bluetooth items (Bluetooth Share and Bluetooth Test). Of course, that didn't remove anything, but I wanted to make sure that I could. Then I wanted to see how Bluetooth Share would react without Bluetooth Test. I unfroze Bluetooth Share.
I was then able to turn on and off Bluetooth fine. I restarted the phone and Bluetooth came in just like it did on my old phone. I guess I want to know:
1) Is the Bluetooth Test the cause of my problem?
2) Why is it there?
3) If I uninstalled it, would I experience a major hiccup?
There is still the possibility that this was simply a fluke, and very soon I will go back to the old bluetooth soft reset problem.
There is, however, one distinct difference between this phone and the last and may be the "drop out" that everyone else seems to be having. I have a Chevy Malibu with bluetooth in the stereo. On my old phone, when I started the car and got going, the word "Bluetooth" would appear on the digital display for about 10 seconds, which means that the vehicle detected and connected the bluetooth pairing. Yesterday, as I was driving in the car, every 5 minutes or so, "Bluetooth" would appear on the digital display.
This leads me to the conclusion that Bluetooth is dropping out and being picked up continuously by my vehicle. Does anyone have any thoughts on this? I'm okay with that as long as when I am talking to someone for more than 5 minutes I don't have to keep calling them back. I simply want to know what you guys think about this issue.

I am beginning to think that the problems I have had are related to the condition of the battery contacts.I have several third party batteries with contacts that are somewhat damaged from the pins on an external charger that came with them. I seem to experience a variety of problems when I try to use them.my original factory battery seems to work most of the time. I have several new Samsung batteries on order and will post again if they seem to solve the problem.

i had the same problem and it started with JMT so I switched roms countless times and the problem kept coming back. It would work for a little bit but when i turned it off it would not turn back on. I decided to go back to stock to see if the problem was still there and it was gone. Since then I have rerooted and once again flashing diff. rom every other day and bluetooth works just fine.

Well it seems no answer was found. I'm having the same issue as stated above. In my case, my bluetooth (custom ROM) keeps trying to turn on with the message "Turning On Bluetooth" until I soft reset the phone, after that it works fine.

Was having bluetooth crashes for months using CM 10.1 on a T989 (no custom kernels)
Would crash anytime I tried to connect to car BT audio, or would simply not start up.
Flashed this yesterday.... and no crashes!
http://forum.xda-developers.com/showthread.php?t=2174100
For flash: Wiped dalvik/cache, flashed, fix permissions, reboot, start BT, deleted all devices, re-add.
No BT crashing of any sort for 36 hours now.

Hey thanks! I switched to JMT JB4 and it's not happening (much) now, I'll try to flash it and see if it fixes something :good:

Question Bluetooth turning on?

I don't use Bluetooth that often so I decided to turn it off. First I used the quick tile, but it came back on by itself an hour or two later. So I tried doing it in settings. Same thing, came back on.
Bluetooth scanning and wireless scanning are turned off.
Anyone else seeing this happen or have any ideas? Not a big deal but off should be off.

I noticed that too. I feel like there's Bluetooth scanning in the background and turns on when it is around a device it's connected to in the past. I notice when I get in my car, it's already on and connected to it.

yes it drives me crazy. It turns on after each reboot.

I unpaired it from the car and it still does it. But it knows I am in the car because it suggests I plug it in for Android auto. So I suspect you are right, it is scanning even if turned off and turns itself back on when it sees a know device.
