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:

install gravitybox. go to >statusbar tweaks>disable peek. click it. problem solved!

I know I am many years late but did you somehow manage to solve this problem?
All of a sudden I'm having a strange problem with notifications in the notification bar. It use to be till today when I got an email and I could read the top line then two finger pull down to reveal more. Since today it's the opposite all the notification is showing and I have to two finger push up to get it back to one line.
Any help on getting it back normal would be appreciated
I've noticed this behavior as well. I thought it was just me.....
Its very odd can't find any settings for it. Tried disabling and re enabling notifications but still happening
by default the first notification is expanded, might be you had other notifications before
that does make sense and could very well be the reason then usual do have a pile of emails as well as texts, but binned an email account as it was mostly junk. thanks for reply
I have 2 very specific happenings with my Note 2.
1) At (seemingly) random intervals, my phone's screen will fade on and off displaying some sort of notification screen that I can't find anywhere. I must have hit this in some settings menu but don't know where. It has big white notifications for missed calls, emails, and texts, all of which are always 0 on the screen. Again, this screen fades in and out in under a second. I even tried a screenshot, but haven't been fast enough.
2) At one point I noticed the RETURN button from the keyboard was replaced with a smiley button. Now it's gone. How can I get it back or to stay?
Also... I love ellipses (three periods in a row). The stock keyboard auto punctuates after one period and puts a space in there which drives me crazy.
Any fixes or suggestions on any of the above things I've noticed?
Edit: Screen Just flashed at 9:30 - Maybe this happens on the half hour or quarter hours. I'll keep watch
Edit2: HAHAHAHAHA... It just did it one minute later. I've got no clue.
Ok, so I figured out how to activate it.
It's sensor related. I have my phone under a lamp. I move my hand over the sensors and I get this notification screen.
I don't mind it, just want to know where it is in the settings or if this is something you can/can't disable.
My guess is that its for when you take your phone out of a pocket the sensor can show you any missed notifications.
For the record, it's missed calls, missed texts, and battery level.
Found my answer in the General Section for the Note 2
The feature I'm describing is the "Quick Glance"
Now... onto figuring out how to get that smiley button back instead of the return! :laugh:
I know this is an old post but I am so glad I found this. It has been driving me nuts seeing that screen come on and go away. I tried everything to replicate it. It happened 5 times over the last 20 minutes while I was watching a movie so I googled it and found this. Anyways...thank you!
Has something changed with Oreo, or is this something OxygenOS does? I can't find an option to hide this. Anytime I have my bluetooth headset on (pretty much all day), the Qualcomm aptX thing shows up. It's even more frustrating as my brain keeps seeing the "X" in the notifications area as an error or something that really needs to be closed (bad marketing!).
I can hide the "notification dot" (no idea what that is), but that seems to have no visible effect. I want the whole thing gone, like I could do in Android M/N. Any ideas how?
Until someone comes with a better solution, you should be able to hide the icon from the statusbar by changing the priority in the Categories from medium to low.
Unfortunately, that option is grayed out.
**EDIT**
Figured out I had to tap the words, not the toggle. I was able to set it to "low", but it's still there. Googling finds a lot of people very irritated by it. Looks like it's been retroactively added to the OP3, also.
Thid weird issue started today in the morning, first I noticed that the clock widget had changed size, and that the led me know ring around the cam hole was out of place, but, when trying to write in whatsapp, I no longer could make the keyboard to appear by taping the wrinting field, in fact, nothing located in the bottom worked, what is odd, the bottom gestures worked, as I hid the nav bar since day one, tried everything, changed dpi, changed keyboards, retired the screen protector, wiped cache, to no avail, reluctantly, I updated to android 10, but no luck, after digging more, I found a work around, I changed the resolution from quad hd to full hd, now all is normal, but, this is just a work around, not a real solution, somebody have an idea of what would be the reason for this?
Did you have your phone linked to windows, your computer online and the phone screen displayed at that time? In this case, if you chose to use your computer's hardware keyboard in Your phone settings on your computer, then, when trying to write something in whatsapp, the virtual keyboard on your phone is not displayed or it is partially displayed. In my case, using the AI Type keyboard, only the top row of the keyboard was displayed because the app thought I'm using my computer's keyboard.

Thanks for your reply, but no, in fact I have never used the phone in that way, something else caused the issue

Was your phone charging at the time by any chance?
I found the solution!
I had the exact same problem with my note 10 plus, the gestures worked, and I tested the bottom part of the screen to make sure everything was working and it was, but the buttons in apps like instagram at the very bottom of the screen still were unresponsive most of the time. The solution is to ho to your settings, switch the navigation bar to the other gesture variant and then back to you preffered one and it should work. It worked for me.
Thanks man, I just found what triggers the issue, as odd as it seems, changing resolutions from qhd to fhd id what causes the issue, odd, because I used a bixby routine to save power at nights, by setting medium power saving, which among other things, lowered the screen resolution to fhd, when the routine ended, it should reverse to qhd, and that precisely triggered the issue, I used this routine for months, until, out of the blue, it started to cause this problem
