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.
Fon22

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?

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

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:

[Q] Gyro sensor not working

I've just discovered that my gyro sensor doesn't work. I am running rooted stock 4.1.1. The phone can not detect tilt movements. And under Settings->Motion->Sensitivity settings->Gyroscope calibration, the blue dot does not move from the center, no matter which orientation the phone is held. All of the options under Motion don't seem to work. I just want to see if anybody else has the same problem before calling TMobile.

Firstly, this should have been posted in the q&a section.
And the blue circle isn't supposed to move. You lay the phone on a flat surface and it calibrates itself.

Moved to Q&A

Sorry for posting in the wrong section. You are right about the blue dot not moving. I downloaded a few apps that detect sensors and all built-in sensor seem to be working as they are supposed too. I have problem for example of taking screenshot with a palm wipe or zooming picture by tilting the device, muting phone by turning it over, etc. None of these features work on my phone. Will try to explore more to see what the real problem is.

Before you go off the deep end, run the test on the sensor.
in the stock dialer:
Quick Test Menu
*#7353#
select the accelerometer tester and ilt the phone whatever way you want. If the arrows don't change, then the sensor isn't working. If the Arrows do change, then all good, no panic necessary...
Good Luck
Aloha

Thank you for your help. I ran the sensor test and the sensors work. I also turned on the Motion switch but the Motion features still don't work for me. Maybe this is a software issue. I will continue to explore and will report back if I've found something.

Hi,
Please do the following:
Pull the top notification bar down by using a downward swipe.
Tap on the Toothed Wheel in upper right corner
scroll down till you see the System divider (below the Add account line)
is Motion ON on the right side of it? if not, turn it on.
Tap on the word Motion
Are any of the options you want to use set with a check in the box?
if not, put the check in whatever you want to use by tapping on the box on the right of the function.
Example:
If you want to use Palm swipe for screen captures, tap on the box on the right of the option.
the boxes toggle these options so if you want the option off, then tap on the checkmark and it'll go off.
When you're done, click on the back button on the right side of the menu bar below the screen till you get back to the homescreen.
You are done, and the selected options should now function.
simple huh?

Thank you, bobolinko. I've been doing exactly what you described and no motion feature works for me. I begin to think that my software has a problem, because it does crash occasionally and software upgrade check hangs forever in the "checking for software updates..." screen and never comes back, no matter if I am on wifi or on 4G. Let me reinstall stock firmware and report back.

Try it like this:

Thanks for the video. I did exactly as shown and nothing happens. I never tried Motion before until I needed to capture my screen and discovered that it doesn't work for me. In the mean time, using PWR and HOME button at the same time does allow me to capture the screen, so I don't really need Motion feature working for me. I am just thinking that my software has a problem and I will need to reinstall stock. Thanks a lot for your help in any case.

Turn off knock on?

Hi guys, does anyone know how to turn off knock on on the G3? Tried looking for it in gestures settings like in the G2 but can't seem to find it. The g3 keeps waking while in my pocket making it feels constantly warm. Anyone else experiencing this? I don't mind just using the button at the back to wake it. The placement for the button is quite comfortable actually.

I'm sorry to hear this is a problem on the g3, I have this problem on the double tap to wake code on my Nexus 5 and so I just turned it off. I know for the galaxy 2, sorry g2, voice dictation, they released firmware fix for this I think

Can you tell me how you did the wake code on the nexus 5?
And to the op, isn't there a setting in the screen gestures section of the phone to turn it off?

You can turn it off in the hidden system settings menu
Dial 3845#*855# to access it.

It is the very last setting in the list, just scroll all the way down to the bottom.
If you have the Korean model replace the 855 with 400

I turned this feature off as it will save battery life too as it needs to keep the screen driver awake happy using the back button.

we don't have that functionality by default, it's patched into custom kernels and eats 2-3% battery per hour (another reason I turn it off)

Just so you know, I had issues with Knock On unlocking my phone in my pocket so I turned it upside down and the issue is 100% gone !
I think it's due to the light sensor not being 100% in the dark then the taps on the lap unlocked the phone. When it's upside down the light sensor is kept in the dark

I just can't find that setting... Ive looked everywhere. My phone is rooted with towelroot. Is that the problem?

Is it really the light sensor? I think the proximity sensor would make more sense in this case! Otherwise you wouldn't be able to use the knock on feature in the darkness...

Screen wakes in my pocket whichever way up I put it in and I don't want to have the screen face outwards. This is very annoying and didn't happen on my G2 - The screen is clearly very sensitive. I don't want to turn off knock on and I don't really like knock code.

Same here. Upside up or Upside down makes no difference for me. Display from body away seems to be the only real solution...

Looks like a few of u are experiencing the same problem. I have been facing the screen away from me as a solution but it feels so awkward when I m so used to have the screen face in. And I can't find the hidden settings to turn knock on off. They really hid very well I guess.

[Q] Strange issue with touch detection at the top of my screen

I noticed after upgrading to Lollipop that it was difficult to navigate menus near the top of the screen in some apps. I turned on the "pointer location" option and sure enough I found very strange results.
i.imgur com/tPdVowo.png (you'll have to add a period after the domain name, new user status prevents me from posting links)
This first screenshot is me running two fingers all the way to the top of the screen, and once i reached the top i ran them towards the edge of the screen. As you can see there is an area where the pointer location bugs out.
i.imgur com/bh5hWeV.png
This image is just a single finger running horizontally across the top of the screen. The top line is where my finger actually was, but the phone also registered extra touches as you can see from the line below. There's even a section where the top line didn't register at all.
This is a Verizon phone, never been rooted, and hasn't been dropped or wet. I noticed while making this post that the area i am having issues with aligns almost perfectly with the top part of Sense's notification menu.
Is this normal or do I need to exchange my phone?

I am having the same issue with my phone. When I turn on show touches in developer options or install a multitouch test app, it'll show an extra touch just below where I'm touching but only when I'm touching at the top of the screen. Stock lollipop, never rooted, no water damage.

Bottom edge of touch screen not responding

So, last week I bought the P2. So far I'm very pleased with the device. Next to the known audio sync issue I ran into one other thing that still bugs me after a week of use: the bottom edge of the touch screen doesn't seem to respond to touch. When I slowly slide my finger from above the screen over the edge of the screen, it immediately picks up my finger, even when only a small part (maybe a millimeter) touches the screen. When I do the same thing at the bottom of the screen, it will only start registering my touch when I'm about 6mm in.
6mm doesn't sound like a lot, but it's enough to make me miss-touch the space bar half of the time. I thought I'd get used to it, but it is still quite annoying... Is this the same for all P2's? I'd like to hear if anyone can confirm this.

Same problem here, it seems that when you hide the on-screen buttons that area is effectively useless. On 6.0.0 and 6.0.1. I have no idea how to fix, but you definitely aren't the only one

i too had experienced same problem, while playing Asphalt extreme, it doesnt let me press the NEXT button

Well, I'm glad that my phone isn't broken. Let's hope it's a firmware issue and not a hardware one!

Check your keyboard set up. I have hidden buttons and the whole Spacebar is active to touch. Right to the bottom of the visible Spacebar. There is a gap slightly narrower than the Spacebar beneath it at bottom of screen. This does not respond to touch. My advice would be to be a little more accurate with typing . As there is no way to fix this and keep hidden buttons. Gesture home button, hidden navigation buttons and big battery are best features of this phone!

I wouldn't even have noticed this issues if you hadn't pointed it out. It's present, but it doesn't really bother me too much. Especially since I switched from my G4 which had me miss the spacebar and hit the home button way too often lately for no particular reason. Not having those softkeys is still an upgrade for me ^^

i am sure its definitely a SOFTWARE problem, official lenovo forms also has a thread about this problem..
so lenovo would patch up in their next update

It is software, but it won't be patched. There needs to be a certain amount of space at edge of screen (dead zone) to allow swipe up of navigation buttons but also avoid unintentional swipe ups. They could tweak the size of the dead zone I guess, but I don't see it happening. Alternatively they give an option to totally deactivate on-screen navigation buttons and accept some apps may have issues.... I guess it is a trade off. As I say, I cannot see Lenovo changing it.

The last option would work for me I guess, although you do need the navigation buttons sometimes for older apps that still use the menu button.

Ah, found it. They say it's required for the "swipe up" gesture... Seems strange to me, but let's wait for another reponse from Lenovo...

I have the nav bar enabled all the time so I didn't noticed this issue.

But why there is no option to turn the swipe function off, because we can use the full functionallity with the home button?..

When I slowly slide my finger from above the screen over the edge of the screen, it immediately picks up my finger, even when only a small part (maybe a millimeter) touches the screen. When I do the same thing at the bottom of the screen, it will only start registering my touch when I'm about 6mm in.
6mm doesn't sound like a lot, but it's enough to make me miss-touch the space bar half of the time. I thought I'd get used to it, but it is still quite annoying... Is this the same for all P2's? I'd like to hear if anyone can confirm this.

Have u checked through Lenovo app in the phone? Run diagnostic through the app, if any point in the screen doesn't register the touch, you should be able to claim warranty with Lenovo. I had the same problem, and Lenovo service centre gave me a new unit....

That is not the problem. And if you try the touch screen test in the Lenovo app you see the the bottom area of the screen is white and it cannot be tested. What he is talking about is not a hardware error, it's just a poor implementation in software.

Is there anyone in here that have root that have tried Immersive mode? There are apps in Play store that lets you activate this. Does this help the bottom of the screen to register touch?

Is any custom rom resolve this problem? Because I will unlock my bootloader and root my phone to increase the headset volume.

I understand that there's potential issue with the software as many has reported as well... However it's good to confirm that it is not a hardware issue... In marshmallow, you should be able to test it, it won't be whitish... I tested before when I'm claiming warranty for my previous unit... Same issue, space bar does not respond...
