Back button Galaxy S Vibrant GT-I9000M problem

Hello people. As you may know, when you want to take a screenshot in the Galaxy S Vibrant (Android 2.2) you have to press the back and home button simultaneously.
The problem with my phone is that sometimes when I touch the back button it turns off and gets into screenshot mode, I mean it waits for me to press the home button to take a screenshot, and sometimes the 3 buttons stop working because of this issue.

TL;DR: Back button problem, stops working when touched and gets into screenshot mode.

Is there any fix for this? Anyone could help?

Thanks in advance.

So far I've tried a soft reset and battery pull. I did not do a factory reset because when I bought the phone from Bell it came with 2.2

Ok so I went to Bell, they changed my phone AGAIN. Yes, this is actually the 4th Vibrant I get from them in less than 2 weeks. The first one just had a sudden death, one night I plugged it in for charging the next morning the phone died. The second one had this issue as well (back button) the funny thing is that when they gave me this phone, it was already screwed and I was able to show them before leaving the store, therefore they gave me another one (third one) which I had for a couple of days before the back button went crazy. So Today I went there again, the guy told me that probably I was causing the problem (yeah I raged!) but eventually they gave me another one. Let's just hope this one works flawlessly (fingers crossed)

Thank you for your help anyways, hopefully I won't be posting this issue again

All of them came with 2.2

Hopefully this is the one! anyway if something happens next time I'll send it to repair.

I had the same problem and I googled until my fingers bled and I found the solution.

Bring up your phone dialer and dial this in   *#*#2663#*#*

Update the touch key firmware at the bottom.  This fixed it for me and I'm in love with my android all over again.

I noticed you have the 1900m, so hopefully it still works for you.   It's a shame that they don't update this stuff at the time of purchase.   It only takes a few seconds.

Hi,
I had the exact same problem and was desperate about my new acquisition, but since my phone is model GT-1900M, I did tried the solution above, and it did solved my problem.

Thanks to who ever share this with us.

Ok, it's been a week now and I haven't had any issues with the back button since I did the upgrade.

So, I'm assuming it works! If there are any issues in the future, I will post them to you!

Cheers.

I confirm this issue. I have a GT-S5660 (Galaxy Gio) and I noticed this for the first time after I upgraded from Froyo to Gingerbread. However, I had only had my phone for a couple of days when I did the update, so it may or may not also have been an issue with Froyo. I have been worried that I have somehow wrecked my touchscreen so that the "back button freeze" is psychical. Fortunately; i found this thread, confirming that this is a very known issue, affecting different users with different phones. It can't be that many broken touchscreens, now could it?
