I've had the focus flash for a few months now and love it. I had no major issues until a few days ago. I've looked through many of the threads and none quite describe the issue I've been experiencing so I hope this isn't a double post.
Sitting idle, my phone's touchscreen will become completely unresponsive randomly without being touched, without receiving a text, or anything else. The phone still responds to every button outside of the touch screen area: the back, home, search, camera, power, and volume buttons. On top of becoming unresponsive, the display will not shut off. If I press the power button, the screen will go dark for roughly half a second then turn back on and I'll have a lovely view of the locked screen.
That should sum of the issue I've experienced. I've tried several things to resolve it but nothing really works. First and most obvious, I tried hard rebooting it (hold the power button down for however long until it restarts). The phone would boot back up and do the same things mentioned before.
Second I tried yanking the battery then restarting it and still no success. I tried leaving it off without a battery in it for about 2 hours then booting it, still the same thing.
What does clear the issue though is plugging something into the mini usb. If my usb cable is connected to the phone it works beautifully, like the day I open the box. This is however, only a temporary fix as I don't really want to walk around with a cord hanging from my phone nor do I want to cut one of my wires to create a dongle in order to use it/ not kill the battery in a few hours.
EDIT:: Plugging in a mini usb has a tendency to, but does not always work. However actually charging the phone does resolve the issue while it is charging.
I apologize for the lengthy post, but I hope I covered most, if not all, of the necessary information for debugging purposes. I appreciate any information anyone has or if you need more info on my part just ask.
Thanks in advance for all the help.

Question are you using a screen protector or how often do you clean your screen. I noticed that if I do not keep a clean screen. It does get a little unresponive and I have to press a little harder. But after I clean the screen it goes back to like new fast and responds.
But nothing like you describe where everything is locked, which sounds like a hardware issue
It is random or does it happen every hour or few minutes..?
How long has been since you have done a full reset of phone like it was brand new..?

Hey sorry for not responding sooner, got caught up at work.
I do use a screen protector, one from AT&T. However I'm 99.999% positive it is not because of the screen protector.
It does happen randomly, sometimes not at all during the day and other times it could last an entire day. What really confuses me is why charging the phone makes it responsive.
I talked with samsung technical support and we did the standard procedures so my phone has had both the soft reset (through the OS) and hard reset (holding camera and volume during boot up).

Sounds like it could be battery related or sensor related..
if does not happen when plugged in via charge, does it happen has well if plugged into pc or does it happpen only when on battery..
Doubt samsung would do this with you. Last time I spoke to a samsung rep they where only trained in android. They had to transfer me to Windows Phone Tech..
Have you tried built in diag yet..phone: ##634# - then *#0*#, then select touch, what happens..First test post results Spec Min and Max then select next, now start at the top of that screen and follow the boxes around drawing a line, then middle, then open boxes. Does it pass the test..?
Else checks these has well..Post your battery settings..Sorry for having you do this..but I would like to compare your's to mine..

As long as the phone is charging the touch screen works, either outlet or pc. I experience this only when it is running on battery.
Thanks for the diagnostic codes! I never knew about them. After running the test for touch I received the following info:

Second test I was able to draw around all of the boxes and pass, but I learned I cannot draw a straight line on a touch screen for the life of me.

Interesting reading those diagnostics. I didn't expect to see 0's for almost all of them. There are also 2 options at the bottom of the screen, Qstar and LOG ON.
I don't know if I'm going crazy or not but it seems this happens most frequently around 80% battery life. I usually charge the phone to upper 90's at night and by morning it is around 83%ish and decides to act up. I let it sit for a few minutes and it decides to work fine again. Could just be coincidence, but it does make sense that it could be the battery.

I noticed that the phone screen was on in my shirt pocket. Took it out and the screen was unresponsive. Held the power button down to force a power off and turned it back on and the screen worked initially, but then became unresponsive again. My battery down to about 20%, so when I got home I plugged it in and the screen was working.
Got up this morning and unplugged it and it seem to be working OK. Drove to work and as I got out of my car, noticed that screen was on in my shirt pocket again. As you mentioned, all of the button work, but as soon as you push the power button the screen goes off and then comes right back on to the lock screen.
Performed a hard reset this morning and the screen was still unresponsive. I could not even press the Setup button after the format system. Once I plugged the phone it, the screen became responsive and I was able to enter Setup and get the phone configured.
At this point it functions just fine as long as it is plugged in. The minute I unplug it the touch screen becomes unresponsive. Taking a trip to AT&T at lunch time.

Hope you have that same kind of luck.

Sorry did not respond sooner had a busy weekend..
Else if "no contract" you will have call Samsung and ask to speak to a Windows Phone Tech..And try to explain to them. Even better if you could take a video of the phone in unresponsive state and upload to youtube for them to view..
Glad they replaced it at the store and hopefully this one does not have the same problems..

I should have my new phone around Monday. If it's an issue related to the battery then I think I'll experience it with the new phone as well using the same battery. If that's the case then at least there will be a solution to this problem, if not then I feel bad for anyone who runs into this after their warranty expires.

Glad to hear that you got it fixed, and it was not the battery, hardware itself.
Since you sent it in for repair to Samsung you should have gotten and email stating what they replaced, at least I did when I sent mine in for repair that will give you some idea. But I am guessing PBA aka motherboard..

After I had AT&T replace mine on the spot when I had my issue, I found this post on the AT&T forums:
Samsung Focus S screen malfunctions unless plugged... - AT&T Community Support
On the last post that user has a suggestion that may have some merit if the problem reoccurs. Just an FYI.

I'll keep that in mind when it happens again, thanks tpbklake!
On a side note, do either of you know of any cases that protect the port and might possibly delay this from happening again?

Weather Resistant Cases would offer best protection..
OtterBox 2000 but it is bulky..
I use a this Belt / Pouch Camera Case - fits perfect no movement of phone in case and has room for extra battery has well. found it at best buy.

Have you tried cleaning all the button, usb port, and sensor areas ?
When did your purchase your phone ? do you have insurance ?
Noticed Nokia announced the 610 which looks really good..
