When in call and placing the phone face down on a surface, the speaker phone should get activated. In my experience it only seem to work like this on the odd occasion, the green icon comes on every time on the back of the phone but the speaker doesn't turn on all the time.
I presume it is a firmware issue as the speakerphone works o.k when activated form the screen and the G-sensor works fine in other applications and when you try to calibrate. Also on the occasions when it did work, there was an annoying lag (around 3 to 4 secs) before the speaker phone turned on.
Anyone else experiencing this?
In my (short) experience with the phone it has worked well as long as the device is completely flat on a level surface, I had a single sheet of paper on my desk and placed the phone down to make a speakerphone call and it kept cutting in and out... once I moved it off the paper and onto the desk fully it started working properly.
it all seems a bit too fickle for my liking but when it does work it is pretty amazing.
I've had one call when I think the second microphone didnt cut in as the caller was complaining that they couldnt hear me at all until I picked it up again.
Apart from that it has been quite good
I think you might be right, I had only tried this feature by holding the phone face down in my hand. When placing it on the computer desk, it seem to cut in and out, obviously not level enough. They must have done this to prevent the speakerphone coming on accidentally (which could be embarrassing).
It's worked fine for me I've just tried it on slightly raised cardboard CD cover which is on top of a USB drive, which in turn is on top of a desk drawer unit, which in turn is on top of an old carpet. It's a feature I didn't think I'd use, but actually I do.
I tried it also, but in my bedroom (on my bed).
the led on the backside glows green, ans sometimes red (when i move the phone?).
but it doesnt go on speaker... realy annoying..
i didn't try it on a realy flat surface, like a table or something. should that do the trick?
is their a way to adjust the threshold of when the sensor activates the speaker? perhaps a rom hack in the future?

I've been doing some experimenting using a level table and hard place mat
There is a very low tolerence for the tilt of the phone - approximately 5 degrees from true level (any direction) within which the speaker-phone will activate.
Any thing outside this "envelope" and the speakerphone deactivates.
I thought that the proximity sensor maybe involved in the decision making - but it doesn't seem to be!
IMHO Something like having a slightly wider tilt tolerance and using the proximity sensor would have made more sense.
Hey guys,
I was talking with a guy from my bank the other day, and the guy was mumbling something which I couldn't hear, and after asking him what did he say, he said I was pressing some keys on the phone which was a bit annoying..
but in reality I was just holding the phone to my ear and my cheek was dialing.. too embarassing.. :/
I know theres this proximity sensor on the Samsung Galaxy S, but I dont know when it is used exactly.. So if it isnt used specifically in situations like this (during call) then I think there must be a mod...
Can a Mod be built such that when the phone is held against the ear during the call, the phone gets locked, the keypad gets tucked in and display brightness gets dimmed and when its moved away from ear it gets unlocked by itself (even if there's a pattern lock), the keypad comes back on the screen and display brightness goes back to normal?
is this cool or stupid? you decide...
The proximity sensor works like this. When you cover the sensor, usually with your ear or side of your head while talking, it turns off the screen. Maybe yours is faulty? Mine is working very well, a lot better than on my previous device.
Are you female? Or do you have long hair?
My moto milestone too had that issue with long hair. It was a bad proximity sensor.
I have not had any such issues with my galaxy. : touch wood :

You can NEVER HOLD A PHONE WRONG(well unless that phone is an apple)
Try asking someone else who has long hair to make calls and see if the sensor works or not.
Then do the same thing with someone that has short hair, i.e. no hair over the ears.
If your tests are inconclusive, download the sensor test from the market and see what happens when it is placed near your palm first.
If it works as it is supposed to then next try your ear and face...tuck you hair in once. If it still works then try it without tucking your hair.
I really hope samsung did not use those defective moto sensors.
tl;dr version download sensor test from the market and ask a bunch of people to check the sensor.(You will see everything on the screen. You dont need to make half a dozen calls)
Get back and we will see what happens next
All the best

Try pushing the screen lock button during the call.

LOL NO! I'm a guy.
I have tested the proximity sensor, and I started observing when I made a call.
the screen locks when I hold it to my ear and unlocks it when I move it away.
guess I didn't enable pattern lock earlier..
problem solved
(I posted this first in the Desire Z forum. I didn't realize there was a separate G2 forum. I even looked for it.)
I've had my G2 since the 9/29 and on several occasions I've noticed the trackpad triggering itself when my finger is no where near it.
Once, I was in the market looking at a list of apps. Normally, when you swipe on the trackpad in there it selects an application and highlights it orange. This randomly happened all by itself. If I touch the screen the selection goes away, but then it would suddenly appear again a few seconds later.
In Subsonic it even jumped around between a few controls.
Another time I was playing Wordfeud and it spontaneously highlighted the Pass button. This time I grabbed my old G1 to shoot video of it happening. I must have shot at least 10 minutes of video and it happened twice more, as I recall.
Update: Here's a video of it happening on the home screen: http://www.youtube.com/watch?v=b9-Yu4DSimw
Anyone else have this problem? I can't reproduce it at will. It seems to happen randomly while I'm holding the phone.
naw, but i've noticed my trackpad will occasionally bring my display back to life when it's timed out - will not do it predictably, but 2-3 times out of 10 tries, it will
have no idea what's going on, but would love to be able to use it to wake the phone up - much easier than using the power button
Hmmm, I have my phone plugged in via USB right now. I have debugging turned on, and "keep screen on" enabled. So it sits there dimly lit after 2 minutes. I was going to leave it alone and see if the trackpad spontaneously moves when I'm not holding the phone.
So far it has not, but just now the screen lit back up to full brightness all by itself. This normally happens when you touch the screen, a button, or the trackpad.
In all previous cases of my bug, I was holding the phone. I heard that the trackpad is capacitive, just like the screen, so maybe holding the phone a certain way can mess with it, but sitting on a desk it won't. If I let the phone sit here long enough, maybe I can refute that idea. If a home screen icon suddenly becomes selected, I'll know that it can happen even when I'm not touching the phone.
In any case, I can't explain why my screen woke back up from being dim.
Yea the touch stuff is set off by heat so maybe it felt some heat from somewhere and thought that you touched it. Thats about all i can think of on that one.
I'm pretty sure it's triggered by electrical capacitance, not by heat. It's either optical or by capacitance (and I heard it's not optical). I don't think any sensors like this use a heat detection mechanism.
To test this, you should be able to hold something cold with a similar capacitance as your skin, like a cold hot dog, and operate the trackpad using it.
See: http://en.wikipedia.org/wiki/Capacitive_sensing
Yes , I noticed mine doing the same thing. If my finger were to hover anywhere near the trackpad it would flash and move around. It doesnt happen all the time but it has happened. I also have had some issues with the sim card and memory card not being read. The memory card I had to put it on my pc transfer all the data, re format and scan the card then reinstall my data to the card. Which has fixed the issue. I suspect a download from the market may have corrupted my memory card.
G2 running stock 2.2

rooted
2.2 Cyanogen 6.0 kanged
As promised, here's a video of it happening: http://www.youtube.com/watch?v=b9-Yu4DSimw
So, at first I thought the trackpad was optical, but someone on reddit assertively said, "no, it's capacitive." So I believed him. But now I think he's wrong.
I believe that if the trackpad is capacitive like the touchscreen, then anything that can interact with the trackpad can also interact with the touchscreen. I used a piece of cloth to interact with the touchpad and it did not interact with the touchscreen.
Here's a video I just made: http://www.youtube.com/watch?v=zYaSzwZGlvY
(Shot with my G1) The cloth easily moves the trackpad around, but it's impossible to get it to register a touch on the screen.
Also, the trackpad is perfectly usable even when your finger is completely covering it. Try it with your thumb even. You can completely cover it then still move around your thumb and your selection will move around. I do not believe a capacitive device would detect the difference between full contact on one place on your thumb and full contact on a different part of your thumb, and especially not the direction of change as you move it. Capacitive touch screens rely on moving the point of skin contact, which never happens if you're touching the whole thing at once. An optical sensor on the other hand would be seeing your fingerprint move.
Thirdly, when you look at the trackpad in direct light, it looks like dark, transparent, purple plastic. I believe it's transparent yet purple because the wavelength of light it emits can go through the plastic, but is not visible light. Infrared maybe? Ultraviolet? I think it's very similar to the "black" CDs for the original Playsation gaming console. They were actually very, very dark purple but that was completely transparent to the CD player.

Fourth, I can't get this bug to happen if I hold the phone perfectly still. It only seems to happen when I move it around in my hand. I think the sensor is "seeing" movement when I do that.
And here's the proverbial nail in the coffin: http://www.youtube.com/watch?v=GOQukQxwajg
Electrical tape doesn't stop a capacitive touch screen, but it renders the trackpad useless.
It's probably a simple IR LED and photodiode operating in much the same way an optical mouse operates. One way you could check is to point an old camcorder at the trackpad. Old camcorders tend to have weak or no IR filters.

My old G1's camera has no problem seeing the IR from my TV's remote, but it detects nothing coming from the trackpad. However, the remote is designed to reach a lot further than the trackpad, so maybe the trackpad's LED is just very dim.
I don't have anything else to test it with.
yes, i have had this problem!!...it did it on my home screen, just starts switch home screens left and right...this was like two days ago...it hasn't done it since,still debating if i should get a new phone
The trackpad is optical/IR. It responds to infrared. If you go out on a sunny day, your trackpad will go wild. The new blackberrys have the same problem. I really do not think there is a fix, and it's pretty annoying. I've owned a Blackberry 9700 since January and I never could find a way around this, no matter what sensitivity setting I had it on or how much I updated the OS.
I've noticed the same thing with the G2.. in sunlight, the cursor goes crazy.
If there were ever any sun in Rochester, NY I would test this. I assume It's only a problem if the phone itself is in direct sunlight. Is the the case? So, if I shield it with my own shadow I'd be ok?

I just noticed this with my G2, kind of annoying, ha. So I experimented and found that nothing happens while holding the phone still or while it sits on the desk, or with the room's light off. But, if I tilt it around with the light on, it acts up.
I think it's detecting the light behind me.
i think its kinda cool. doesnt bother me cuz it makes my phone feel.... alive in a sense. but it is very light sensitive. im freaking loving this phone. not a single complaint
Roughly a week ago I'm laying in bed playing Candy Crush. My girl comes in and ask me to come help her with the pool. I leave Candy Crush up and running, but turn off the screen and slide the phone into my back pocket. I dumped a few chlorine tablets in the pump, and we move the ladder to the other side of the pool (above ground pool). I come back in to finish my game and all of the sudden, S-Voice and Task Manager continuously pop up while I'm trying to play. I ODIN my phone and reset the flash counter getting it ready for warranty replacement, but it stopped afterwards. So of course I write it off a software bug / glitch.
So this past week I would go and put my phone on the charger at night, and wake up the next morning to find that my phone had stopped charging throughout the night. Now sometimes I can't even get it to start charging. I've actually sat there and seen it stop charging, Also, the last time I ODIN my phone, was the last time I was able to get any computer to recognize my phone. I've also had my phone randomly pop up and say that it is "docked" when it's not plugged into anything.
The only part I don't get is in the beginning why it was randomly acting like I was hitting the home button. Is it possible that the charging / data port could cause this type of behavior? I've never used one, or even read about one...but I assume the dock has features / buttons that would also be like hitting the home button. So I'm assuming that it's possible to emulate the home button being pressed through the charging / data port?
Thanks in advance.

Could it have gotten wet at some point? Sounds like that kind of effect, but I'm sure you would have mentioned it...
Maybe the home button got pressed and stuck while in your back pocket?
Can you still return it?

i don't know why people would put the phone in their backpocket. or WHY they even bring their phone when they're helping with the pool.
you didn't state if your phone has a case, if it was a tight sqeeze for your phone when you put it in your back pocket, but chances are, your board is damaged. you COULD try and if they ask, you can alway hope they don't check and just probably replace it. mention that your charging port failed and if they tried to charge it and it didn't work, they MIGHT accept your warranty.
I put it in my back pocket verses my front pocket because it's NOT a tight squeeze. I also carry everything else in my front pockets, keys, lighter, flash drives, ect... Things I wouldn't want pushing against my phone. If I sit down I remove it from my back pocket and sit it in front of me on a table or something. I do have a case and it covers a good portion of the phone, including the charging port, headphone jack, and stylus. The chances that it got wet is slim to none. The reason I took it with me is because I have a very sick family member, and if they happen to call for whatever reason... I don't want to miss that call. Regardless, they did replace it under warranty.
I have enabled Pocket mode and 95% of the time it works great.
But every once in awhile, I'll pull my phone out of my pocket and go to unlock it but it brings up a screen that says "Pocket mode is on" and wants me to press randomly appearing spots on my display to prove that I'm trying to unlock it.
Is this a known bug or do I need to try a factory reset?
My screen is clean and my case is a semi-minimal case and I've rebooted. It's been going on for a long time now.
This happens to me also sometimes with the original carbon bumper case. It happens when i pull out my phone quickly while pressing the power button, but the top of the phone is covered with my pants.
You can trigger that if you cover the ear piece with your hand an try to unlock it.

So, maybe I need to be slower to press the power button after removing from my pocket? hmm okay thank you.
