NOTIFICATION BAR scrolling down without touching it: Static Electr & Capacitive Scrns

NOTIFICATION BAR scrolling down without touching it: Static Electr & Capacitive Scrns
I would like to know if anyone else has experienced this at least once. I didn't post here as a thread til I got confirmation from one other DESIRE user that this has happened to him as well.
I don't know the exact triggers or even the exact scenarios, but this has happened several times to me already:
I am using the phone in horizontal mode and tapping menu items or inputting text, and my finger is nowhere even close to the Notification Bar at top of screen -- and yet suddenly the Notification Bar will auto-scroll down, interrupting what I was doing. Repeated times. It would happen again, with no accidental slippage of my finger or anything. My finger would be nowhere near the bar.
I am wondering if there is any kind of static electricity effect with capacitive screens that can set off a menu action.
So I am asking the experts here. Is that possible? Is it anything that was reported with the Nexus One?
RELATED (1): After this happened a few time in ONE SESSION using the phone -- it happened to be while uploading videos to YouTube, I wanted to test to see if I moved my finger close to the Notification Bar would this perhaps trigger this auto-scroll-down. So I moved my finger just slightly above the surface of the glass at the Notification Bar, and it didn't make it scroll down, but on this occasion, it set off a kind of jumpiness whereby the notification bar was rapidly shifting up and down a few pixels, as though it was receiving input. Has anyone seen this happen? I have not yet been able to get this to repeat from that session of using the phone a few days ago. I was lying down on my bed, and I'm pretty sure sheets produce a lot of static electricity, so this is my layman's question. Is there some causal effect here?
RELATED (2): A variation on this problem would be where I am actually trying to select a menu choice, and instead of my finger-press activating the menu item, instead the menu item jumps up slightly, and does not get selected.
This, again, happened when I was in ALBUM MODE, watched a video in horizontal display, then tapped-and-held the video to bring up the context menu that includes various SHARE options. One of those options is YouTube (the last item of the menu). I would try to select "YouTube" but the menu jumped upwards slightly, and wouldn't get selected.
I have been able to reproduce this one (Related 2) today, days later, in totally different environment .
So, a bunch of questions:
1. Is there such a thing as a static electricity effect that confuses the screen?
2. Are there other kinds of known screen-response problems that could be at play here?
3. Is this something that sounds like "it's defective so return it", or is this a somewhat common experience, sporadically?

the only time I've had that happen to me is when I use a cheap charger I've got and yeah the screen just skitses out. I am using a hero tho but this is the first time I've seen anyone else encounter this so I thought il'd churp in.

I had something similar only once.
The notification bar went mad. It was flicking up and down constantly without me touching the phone at all.
I had to pull the battery to fix the problem.
Hasn't happened since.

Happened to me also when loading a ROM in Nesoid.

So I'm not sensing any concerns re; any defect... but still wondering, since I don't know the physics of capacitive screens... Is static electricity the culprit? Never happened once on my GSM HERO... so something is at play here.. or is it an intermittent defect that rarely shows up?

The capacitive touch screens work by detecting a disturbance in the EM field on the glass surface. There's a few ways to do it, I think the way mobile phones are doing this is to put a field of their own over the glass and detect fingers on the surface based on what levels of the field they'd expect to see at different points around the screen, and doing some comparisons on what levels are actually detected.
Please someone correct me if I'm wrong BTW.
I've noticed this notification bar problem today and yesterday. Lucky I at least saw how I caused it. My finger was to close to the top right of the screen because of the way I was holding the handset. That combined with the lacklustre multi-touch support on this handset made the phone detect it as a finger swipe that rapidly moved downwards.
I've always had similar problems with capacitative and inductive touch technologies. I don't actually need to touch the desires screen to activate a touch. The worsted was the Zen Micro with the touch controls. I could activate that thing from about 10-15mm away. The touch on-off-dimming lamps too. I usually cycle those through all their light levels with a single touch. Where as my brother actually struggles to activate those, really has to press his hand down hard on them.

Brilliant, Alex... You got right inside my head and answered exactly what i was trying to ask.... the physics of the system.
I'm okay with little glitches here and there, and I am sure I will learn to avoid proximity issues that tend to trigger these mis-fires... just as I learned to adjust my tap-key behavior in typing on the on-screen keyboard on capacitive screen vs all the resistive screens I had used before on Windows Mobile, where fingernails could & would engage the resistive screen -- vs learning that the bottom surface of the finger has to make contact on the keys on capacitive screen... (sorry i am USA and we still resist the world's metric standard, so i don't know the equivalent distance in cm,)... but it's over a 1/4-inch of an upward shift in the position of one's fingers above the capacitive screen from the tip of the fingernail.
But once you train your senses to activate the keys sensors properly, the finger impact behaviors of resistive screens goes away after a while (at least for me)
(oh, btw, I ordered the new HTC capacitive stylus which is a couple of months old now, but is an official DESIRE accessory, so that will be an interesting experience... the thing i miss most about the resistive screen and stylus was being able to scribble notes really fast, way faster than i could ever type -- and draw pretty detailed images or maps and directuions for people. so it will be interesting to see the granularity of control the capacitive stylus will give)
So thanks very much for giving me the exact level of detail I can process as a lay person.. and for assuring me, as the rest of you have as well, that this apparently comes with the territory of this phone -- and therefore should not be seen as a defect. Because i sure as hell didn't want to go shipping this phone back. I can live with an occasional spazzoid misread of intended impact spot on screen...
And, fnally, this was funny -- re the different degree of touch we all consider "normal" --
The touch on-off-dimming lamps too. I usually cycle those through all their light levels with a single touch. Where as my brother actually struggles to activate those, really has to press his hand down hard on them.

I was thinking it is softwarerelated. The bar remains halfway the screen, is in the layer below the active app, and jumps to front upon touching the screen.

I have the Problem, too. And that since Monday. I went mad since yesterday evening so i tried to go back to stock, unroot and all.
But the problem is still there.
How can i fix it? Or is my Phone damaged?!
The Notification Bar scrolls down without touching the display and then freezes the phone. so i must lock the phone and relock it and then i can use the phone but after a short time the same problem came back!!

So I reckon you're an undertaker for a living?

Sorry but i don't understand what you mean
The problem makes me crazy because i have now the stock rom because i thougt it was an issue due a custom rom or a kernel or something.
If you can help me please do that, this problem robs me to sleep
But i havent the Desire. I Have the HTC EVO 3D GSM

Sorry but I do not understand the background of your information which is in context with my problem of the notification bar.

@19Marc89 He meant that you responded to a an old (dead) post. Listen, I'm trying to recondition an old Motorola Milestone (Droid) with a crazy touchscreen problem, whose cause I believe I've narrowed down to static electricity - can you do me a favor and try stroking the glass side of the phone lengthwise in one direction down your sleeve, preferably if you have a wool sweater on? Call me crazy, but this works for me, at least temporarily. I posted more here:

I know I am many years late but did you somehow manage to solve this problem?

SMS showing on lock screen

Is there anyway to remove this & the missed calls? Kind of hte purpose of locking the phone ya know...

Yeah, exactly what I thought!

If you use Handcent SMS, which is much better than the stock app imo, you can enable, disable popup over the lock screen.
You can also tell it to show the popup so you can see who its from but not show the text contents.

i actually think that option is quite useful, being able to see if you have new mssages with one click

I like it alot too, i can see if it's worth unlocking the phone accoring th who did the missed call/sms or mail. It's the main reason why i like senses lock screen over androids stock!

Sense lock screen? How do I enable that....This is my 1st android phone so i know nothing about the OS

if only it did it for emails too!

I realize it has been a while but no body came up with a solution.
I'm don't like the fact that anyone who picks up my phone can see the actual text message on my screen. Having the sms icon on the notification bar is enough, is there way to remove the text from the lockscreen?

Use pattern lock?

Even when using pattern lock, when you wake the phone you will first see HTC lockscreen. So it doesn't help...

No solution to this? It is the most annoying thing. I can not believe that there is no options to disable sms preview on the lock screen. I would make great donation for someone who can fix this

Buy widget locker from market. It replaces the while lock screen with a customizable one

I see no reason why its causing problem. Its only showing a little right?

yeah, it only shows the number (or name) and some words of the message (maybe the first 3?), not more. Don't see where it is such a huuuuuge problem or is your phone always in other people's hands?

well 3 words can make a huge problem, and yes my phone is very often in other people hands But I found a solution. with chomp sms there is a setting which disable this notifications...It is pain in the ass to use two different sms clients but it is better than nothing.

Well I guess a small option could've been included, but I can't see any real issue here really. Every tentht user here doesn't have a Facebook with hundreds of unnecessary people who can take participation in your private lives, and it is not considered a privacy issue, but three small words and a name on a lock screen are??
The real issue here is that your phone should be holstered in your pocket when not used, and not in other people's hands.

well IMO, the issue here is that, when you use a different app from stock one, the unread SMS count does not disappear when you read messages with a non stock app...
That's annoying!

[Q] TouchLockPro or PocketShield Impressions

Anyone using TouchLockPro or PocketShield?
What are your impressions, pros/cons?
Thanks

Touch lock pro is really good but i removed it because some major features weren't working, maybe its just the ROM i used. But its great!

I was using s2u2, but kept having issues, probably has more to do that I don't use a stock rom, versus the program, but I switched to pocket shield and have no issues with it. I don't use all the features, just mainly the screen lock.

hmm good to know...I was about to ask about S2U2 too...it looks great...but I was reading the threads on it and it seams like issue after issue that people are talking about...maybe just the users/roms/or devices...idk

I downloaded the trial version of Pocket Shield...which you can use for 10 days before having to buy it.
Noticed some issues...probably things that just I would notice ...
(1) It enables the ability to select Repeat...under settings>Sounds&Notifications>Notifications>Reminders [I thought this was great...since this feature disappeared after WM 2003]
(2) in the same area...under Voicemail, Missed Call, and Text Messages you can now enable "flash light"...although these options are no available for New MMS...or ...New E-mail...or Reminders
(3) When Reminders go off...the light flashes anyways...until you dismiss or snooze... [I thought this was annoying cause I usually associate LEDS with missed e-mail, text, voicemail, not reminders...]
(4) You have some boost alarm options....where you can choose snooze options....this is basically an alarm to tell you have unchecked e-mail, text, voicemail, reminders etc... BUT the SNOOZE options don't actually work...this seams to never stop...just keeps going and going...even after the reminders and all missed calls are answered :x Edit:OK, so apparently...when this alarm goes off on the lock screen...you click on the item on the lock screen, then slide the screen...where the snooze options are revealed! yaay! ...but no dismiss button :X Ok, figured this out. For Boost alarm options you have a time setting for when you want it to work, plus you can check what you want it to work for, mine kept going off because I had it checked to go off as long as there was something on "today & tomorrow's Agenda" haha oops
(5) After a call...the screen locks...even if this feature is turned off on pocketshield...
(6) strange thing...i think is a feature of pocket shield...that we can't control...the phone screen turns off when you hold the phone up to your ear...even if the feature..."protect screen during call" is off....sortof like the iphone proximity sensor...not sure if our phone already did this...but I don't remember it doing this...before....
...if anyone knows that this is a normal feature...and how to turn it off...that would be great...
(7) For some dumb reason...the TouchFlo3D Slide to Unlock Screen is gone again....and it has defaulted back to the old WM Unlock...if I hold End key down....yaay! (sarcasm) ...this happened strangly the other day too...without this program...and I had to hard reset to get it back :x
(8) No clue why...but after a call...the phone decided to vibrate without stopping...until I pulled out the battery....when i turned it back on ...it went back to vibrating...but stopped after it finished booting...no clue why this happened...but it only took place once...wasn't a reoccurring problem
maybe this is all happening because it isn't the full version...idk...I thought it would be full...just minus access to the skins and it would just disable in 10 days...but idk...
This is all on my stock Rom too....which is nuts

Another annoyance...when you hit the power button...it turns of any media player you had running...so you can't turn the screen of and play music at the same time...unless plugged into external power.
I found that I can turn the screen off...and keep the media player running if I push the PocketSheild Lock button...this gives you the option to turn the screen off...or go to the lock screen...which will turn the screen off too and keep the media player running.
Major annoyance...should just be able to hit the power button and have the screen turn off and lock...with the media player still playing...what if I want to save battery by turning my screen off while listening to music...or put the phone in my pocket with headphones...

Yeah, I don't fault S2U2, it's a good program. I hear from a lot of people that use it and like it, but I was having issues. It's funny to show iPhone drones the S2U2 lock screen with the battery showing (the default iPhone screen?), and they say "hey, when did you get an iPhone" swipe it unlocked, and they say you can't have iphone on a windows phone LOL....priceless.

at least people don't mistake your phone with a nokia,
it's driving me crazy

I used TouchLockPro for a long while. Generally, I like it. I locks well and the unlock with light feature is great.
Recently, the unlock with light feature was added to PhoneAlarm. I use and like PhoneAlarm, so I just updated and now have a single program with my alarm profiles and screeen locking plus a slide to unlock. Handy.

[Q] Next Track while locked

Hi,
I believe this question has been asked tons of times before. However, neither Google nor the search here did return any usable results.
When I have my Desire in my pocket while listening to music, it is a giant pain to guess where the "next track"-button is on the lock screen. It would be terrific, if I could just press one of the buttons which are out of use anyway. As an alternative, I could think of an app which makes the lock screen controls more usable (bigger? gestures?).
Thanks

Notification pulldown not as responsive during phone calls?

I posted this on Android Central, hoping to see if anyone on here has any information regarding this.
So I've noticed that anytime I'm on a phone call, it requires a little more effort to successfully pulldown the notification shade.
Usually I just quickly flick from the top of the screen with my right thumb (and I mean a very quick flick), but anytime I'm on a call, that same motion doesn't fully register. Instead I see that the notification shade looks like it will come down but it retracts as if it was an accidental gesture. In short, it seems like it wants more effort before being pulled down. Once I slow down my pulldown gesture, then it registers and pulls down.
Funny though, tapping the top of the screen registers.
It's almost as if the sensitivity of the screen drops or they've got some logic that makes you use more effort.
Anyone else have this problem. I can't decide if I should return/replace the phone over this. It's really infuriating though.

I think I have experienced the same thing on the 10 and my M7 as well, but I wouldnt call it an issue just yet as it appears to be intentional.
