starts vlingo and goes to car mode

Hi
my sgs2 goes in car mode and starts vlingo "tap to speak" all the times.
Sometimes it thinks its on "charging"
Pls help.

I had this for 2 days. I unnistalled ADw launcher and no problem ever since. Are you on a rooted device?

Im on a rooted device.
I have wiped my phone and tried different roms.
The problem aint going away.

Option 1) Do you have a casing with a magnet in it, or any other magnets (wallet, bag, etcetera) (dunno for sure if the SGS2 has magnet-activated-carmode as well...?)
Option 2) Shortage in your usb connector? - does it charge correctly, does it connect well to your pc?

Thanks for the answer.
I have no magnet nearby. So that cant be the problem
it has happened a few times that it dont sync with the comp its just starts to charge the battery instead.
When i charge the phone. There is no problem.

first post, reading allot
i have this problem to, since a few days.
wiped al data. moved to stock firmware, but the problem is still there.
also causing extreme battery heat and drain from 60% to 0 in like 15 minutes
had adw launcer installed for a week or 2 but no problems.
it seems to me when you wipe all data this cant be a problem anymore.
will try diffrent firmware now.
if anyone has a solution for this problem please post

Anyone sorted this? Mine started doing the same a few days ago. Really annoying...?

I just noticed my SGS2 doing the exactly same thing today! I'm fairly sure it is related to dirt or dust in the microUSB port, since my friend dropped my phone at the beach (not gonna borrow it to him again!) and it got covered in sand. Few hours later, sporadic car and PC modes, sometimes the phone even thinks it's charging. I tried blowing into the USB jack but to no avail... I hope I won't have to return it!!

I think there might be bad microUSB port soldering. Try connecting your phone to pc and wave/move your phone, or tick the cable with your finger. Does it sometimes looses connection and reconnects right after (might not happen every time)?
Bad port soldering does happen for other phones too. But I'm not sure if this will be covered by the warranty. Service might say that you bend the cable/port too much when connected or something.
Anyone tried to bring the phone for the service because of this issue already? If this is the case service should be able to fix it easily.

Last night my phone wouldn't even start charging, so I decided to take matters into my own hands. With the smallest screwdriver I could find, I carefully 'lifted' the tiny PCB in the USB jack while blowing in at the same time. Sure enough, some sand particles fell out, and I haven't gotten carmode'd in nearly 13 hours now. Previously it would do it once every 15 minutes. So far so good, it seems.

I'm absolutely certain the warranty would cover this fault, if I pay $675 for a mobile phone I definitely don't expect it to stop working after I insert the USB cable the wrong way!

Thats why I think its soldiering problem. I did the same thing at it helped for some time, then it started vlingo again a few times, then again is ok for several days.
Does your phone do reconnects to PC when moved? It happens for me from time to time and it is scary that for example ROM flashing can get interrupted.

Yes, it did that once or twice, but I thought it was due to the fact that I was trying to remove other USB cables from my computer and accidentally hit the SGS2 cable. If it is actually a problem with the phone, it could actually be dangerous to flash a new ROM!

What we learned so far:
Problem:
1) Vlingo (car mode) starts sporadically (most often when connecting USB).
2) Phone shows "charging" or just "USB connected" even when it is not connected.
3) Sometimes starts "kies mode" without cable if "USB debug" is not enabled.
4) When connecting USB to PC, phone reconnects if moved.
5) Sometimes charging do not start when connecting USB.
6) Sometimes when trying to reboot, battery image with thermometer appears and phone do not start to boot when power button is pressed. It will boot into recovery (Vol Up + Home + Power). Go to the recovery and reboot from there. t
Reason:
USB got polluted or bended. It also happens if you forced to connect USB cable upside down. My guess is that soldiering of USB PCB gets damaged.
Solution (at least makes it happen less often):
Shutdown the phone, take the battery off. Clean the usb port. If it doesn't help then carefully bend the usb PCB a bit downwards.
If anyone brought his phone for service with this problem, please let us know the outcome.
Edit:
stevee1953 got his phone replaced because of similar issue: http://forum.xda-developers.com/showpost.php?p=15925236&postcount=7

Anyone fund a proper solution for above problem?
EDIT:
I cleaned the USB port with a toothbrush, and the problem is gone.

After cleaning the the usb and bending back the usb problem never appeared again so far (almost a month).

Hi all,
had the same problem (starting Car mode). After reading that some of your guys think it has something to do with dust, smut, etc. I remember my jogging during heavy rain.
I`m absolutely sure, that was my reason for the behavior. The usb connector has been wet.
After some hours (it was dry), i never see the problem again.
So be careful with your usb connector.
Tregobad

I've cleaned out the USB port a bit, and the problem isn't as bad now.
Still happens a bit though.
Just to be sure, people say to bend the USB PCB down? To me, it seems like it's very close to making contact with the bottom of the port, so I lifted it up (by putting a thin flathead screwdriver between the PCB and the bottom of the port to lift it up).
Is this right? Or should I be pressing it down even closer to the bottom of the port?
(I'm saying up = towards the screen, just to make sure )

Got the same problem, I wrote it down here:

Sometimes bending is needed, because this problem will occur if you accidentally plug USB cable upside down or have bend it with cable. USB PCB has to be very near bottom of the socket.
In your case you probably just need to clean it. What I did, I took a matchstick, sharpened it with a knife, then crushed the end (I did with my teeth ), so you get like a small brush. Then I carefully cleared socked with it (might need to make a few, but matchsticks are cheap here )
Be sure to take of the battery before cleaning, because if you just turn off, cleaning USB with something wet will make your phone to boot.

I'm posting my solution in a couple of threads hoping to help somebody out. This problem was driving me crazy:
I fixed it on my phone:
Reading http://forum.xda-developers.com/showthread.php?t=1132588 gave me the idea of cleaning the microUSB port. Of course with the battery removed. I also saw someone having the same problem with a HTC-phone so i guessed it couldn't be a software issue.
I used a non-conducting spray for cleaning electrical wiring (ask for Contact Cleaner), that removes oxidation from electrical contacts and such. I guess one could use Isopropyl Alcohol (from a pharmacy) as well, but i think the contact cleaner is better at removing oxide (reminds me of a less oily wd40).
I used a sharpened toothpick (soaked in spray) to clean the microUSB port but i guess you could soak something like small brush as well (toothbrush?). Once cleaned i let a small droplet fall inside just for good measure.
After a couple of minutes letting the liquid evaporate, i booted my phone to see the bug completely GONE.
The phone has not been in direct contact with water, more than regular humidity, and once or twice in the bathroom while i took a shower. This proves to me that regular use could in fact produce this bug by messing up the microUSB port. And that Galaxy S had an excellent solution by providing a sliding cover.

Touchscreen freeze... ! Help please

Hello guys,
Around a week back, my MT3G slide touch screen got unresponsive for a while. I rebooted around 2-3 times and thankfully the touchscreen worked fine.
Now, I am getting this unresponsive touchscreen more often and I have to pull out the battery from the phone and turn it on again. The last time this happened I had to do this about 8-10 times before the touchscreen would respond. I have no problems with my keypad, 4 buttons or the trackpad, just the touchscreen
I also did a factory reset and erased all the data that I had on my phone and SD card.
EDIT : I just figured that the touchscreen sometimes starts working if you slide out the keypad. But once the keypad is slid back in, it's back to being unresponsive.
My phone is out of warranty so I can not get a replacement I think.
Does anyone know what could be the problem for such frequent touchscreen unresponsive behavior. After a couple of reboots, everything returns to normal.
Any ideas ? I would appreciate any help..
Thanks a lot...

you got a broken ribbon

Hi there,
Do you mean the slide rail flex cable or the digitizes flex cable ?
Thanks

flex ribbon cable
I would say it's the flex ribbon cable which connects the motherboard piece to the screen and home button piece. I've purchased several "broken" my touch 3g slides from ebay that had either the screen shift problem when the keyboard was slid out or screen that was unresponsive/wouldn't come on. Both problems were fixed by purchasing an inexpensive flex ribbon cable like item 170747702766 on ebay. I watched a video and followed along on youtube /watch?v=-jgFHuVWlig (stop at 7:27 and reverse the process). However, my most used mt3gs is now starting to have the screen shift problem again and needs a new cable... it didn't last as long as I had hoped.

Did you try any custom roms?. reflashing/updating the device?
I guess it must be some driver issue!..

i have the same problem.
Could you fix it?

Seems to be a common issue. I've described the process of replacing the flex ribbon cable here - it's not a rocket science. Or just bring the phone to a serviceman who will do the same (if you lucky enough he could even have a spare cable, but I'd advice you to have your own bought from ebay to be sure).

Thank you for the information but another questiion that I do have is where would one get a serviceman that would repair or help repair a phone, usually the technicians are attached to the different cellular carriers and if one dosen't have a contract with them they are not likely to help repair your phone even if it is for a fee. Do you know any serviceman?

[Q] Xperia play noob

HTML:
First time poster in the forum here. Basically I opened up my xperia play to replace the screen which was successful.
Unfortunately there was a spec underneath the screen bothering the hell out of me and so I took it apart again to clean it.
This time however once I put it back together it won't boot up and the only signs of life are a red flashing light.
I have tried swapping batteries and sockets. Still no change.
I hope there is a genius out there who knows the solution to me being a perfectionist.
Cheers.

You need to make sure all the connections are intact:
-the connection between the screen and the motherboard on the top right
-the small connection between the gamepad and the motherboard
-the flex (main) cable between each half of the phone, you have to press the motherboard down into the connector and hear a "click" to snap it in place

It was the motherboard hadnt got that click this time round. Unfortunately i think i have done something to the digitizer as the screen isnt responding to touch now.
The phone is destined for the bin unless there is a way to unlock the screen without the side swipe, as i only use for emulating.
Cheers for the previous help

[Q] LG G3 display not working

Upon power up flashes green then blue, no LG logo or anything else. If i plug USB connection to the PC the PC recognizes the phone any suggestions? By the way this happened after the phone was dropped, no visible signs of the screen being cracked.

Try holding power button for like 30 seconds. Or pull battery

Was this ever resolved? My friends phone did the exact same thing the other night, you can still feel it vibrate across the unlock pads and it makes noise and everything when receiving texts, can even answer calls if you know exactly where to push accept call.
It's the strangest thing.

Looks like a broken mainboard from the drop. Or perhaps cracked screen near the connection to the mainboard.

Replaced the bazel/Screen/LCD, still same issue.

As I said: broken mainboard....

Same friend I was talking about earlier, exact same issue, he had his old phone he was using and just recently we found the issue, it had mild water damage from snow getting in his pocket right around the display connector inside, so we cleaned it up with alcohol, made some colors at the bottom but then would go black again, we took the logic board out, reflowed it in stages on each side so everything was good, tried it again, exactly half the screen (right side) worked perfect, so finally, brought it in, they said the display was faulty and replaced the phone under warranty.
So, conclusion, we didn't touch the display, Bell said the display was broken and just replaced his phone.
We only touched the logicboard and we got it half working, if we knew a better method of reflowing a mobile logic board (chips on both sides so you can't reflow the same way as laptop motherboard) so it was a lot harder but we probably could have fixed it if we kept at it and knew more about what size of the logic board needed the reflow the most
We used a bunch of clay if anyone is wondering, worked it in out hands till it was very plyable, make a pile slightly bigger then logic board, push board flat I to clay so it holds the underside chips pressed and in place, reflow top, repeat once cooled, it got half the screen working from a phone that had physical water damage and corrosion on the display connector so, this will probably work for you.

ZenFone 2 stuck in Asus Cover Mode with no haptic feedback after dropping on floor

I'm adding this thread to document my recent findings, in hopes that it may help others recover from similar issues.
I dropped my ZenFone 2 (ZE551ML) on the kitchen floor the other day. When I picked it up, it was stuck in Asus Cover Mode, even though I don't have an Asus Cover. I was unable to get into the phone, so I forced a hard-reboot. After playing with it for a few minutes, I was able to get the home screen, though Cover Mode would intermittently kick on and off every few seconds. I got into the settings and disabled Cover Mode, but I soon realized that I had lost vibrate and haptic feedback functionality.
I took apart the phone to inspect for internal damage, and I noticed a small hairline crack on the flex cable connector that resides on the charger port board (see attached photo for details). The now-broken connector allowed the flex cable to shift laterally from its original position, leading to connectivity issues and causing the problems noted above. I was able to temporarily fix it by disconnecting the flex cable and reconnecting it to its intended position. As a permanent fix, I ordered a new charger port board from a vendor on AliExpress that ran me about $5 USD. I just installed it yesterday, and it seems to work as well as the original.

May I know how you played with your phone to go to the homescreen? I had the same situation but mine is vibrating. I'm just stucked on cover mode.

I hit it against me hands a few times. It seemed to be enough to allow intermittent access to the home screen and settings.
If your device is still under warranty, my recommendation for you is to let Asus repair it. I purchased my ZenFone with a broken screen and repaired it, so I have no warranty coverage. That said, I'd be willing to bet that you can't fix this without taking the phone apart. If I were you, I'd open up the phone, disconnect the battery from the motherboard and the flex cable, antenna, and vibrator from the charge port board, and inspect for damage. If everything looks good, reconnect everything, reassemble it, and try it out.

Glad I could help!

I got the same problem this morning. Tried the strong magnet mtd recommended in the asus forum but it didn't help. In the end, I found that by removing the cover, and then using your finger to flick on the magnet sensor (near the back button, bottom left of screen) works! After exiting the cover mode, quickly go to settings to disable it.

Thanks a lot
I had a similar problem , but my connector have gotten wet, and wasn't broken. When i cleaned it, the mobile got out from cover mode
