New Storm Touch Screen Observation
-
If it needed to be grounded none of the silicon cases(or otter box) would ever work, right?
Btw, my storm works fine when I press the screen while it's lying flat on a desk here at work03-02-09 04:37 PMLike 0 - there is no design flaw here. it doesn't need to be grounded at all. (although that's a funny theory)

What I find more interesting is that "certain" people on this forum seem to have not commented on this perticular thread or others about the same subject.03-02-09 09:24 PMLike 0 - Out of curiosity, I tried operating my Storm just now with the battery cover off. I held the unit by the top and bottom (fingers were on the "chrome" bezel, which of course is plastic painted with metallic colored paint), no contact anywhere with any of the brass pins inside the battery compartment or any other metal component nearby. Touch screen worked like a charm. Interestingly enough, my screen is working much better right now lying flat on my desk (an Ikea desk, consisting mostly of reprocessed wood fiber packed into the shape of a desk) than it did the other night when I tried it on top of a hard cover book.03-03-09 02:53 AMLike 0
- In order for a capacitive touch screen to work, you must have a slight charge in your fingers to use the screen. Your phone actually conducts this charge to you when you hold it in your hand. The reason that t doesn't work if you aren't holding it is because your natural change isn't enough to register. If it is working without you holding it, this is because you have a residual charge. The phone works in a case because the case still transmits enough charge to register a touch.

I do have trouble if my skin is unusually dry (winter time in the midwest), but i couldn't duplicate your problems with my storm. (many apparently have, tho!)03-03-09 08:37 AMLike 0 - Dev, you did the test all wrong. I never said anywhere in my posts that you should start with a dark screen nor that any clicking is involved. My findings is that if you use one finger and one finger only with the Storm (screen lit up) laying flat on fabric based materials (micro swade in my case) on a seat or a couch, that the screen selection via touch (blue highlight) will be very hard to register or not register at all. The instant any proximity happens to any part of the phone with another finger or body part (initially I thought it was just the door, but now it's anywhere on the phone really) the highlight touchscreen reaction is much better and back to normal.
This does not mean put the phone flat in your lap and try to use it, I think the issue here is that there must be a very small and singular disruption of the field generated by the screen in order for you to see this problem. Any time you have grounding proximity from something else to the body of the phone, it'll work fine. I just find it interesting and wonder what exactly causes this and wanted others to see if their reacted the same way and it appears that it does.
Yes I understand. But in attempt to get a consistant results and determine if the touch/"grounding" issue also affected the click I wanted to start with the screen off, which meant I had to click the screen to turn it on. In doing so I noticed I got a different result in in clicking the screen to turn it on using only 1 finger and not touching any other party of the phone, than if I turned it on while it was being held in my hand. Just like you described with just touching the phione with 1 finger.
After the phone was in the "on" state with the light fully lit I tested the touch aspects and found similar results to what you reported. I then tried to click the lit Icons to see if with the screen lit the click would register (still one finger)
I apologise if my posts weren't clear in this matter and also for the fact I left out that the lap pillow was on the desk for my tests as well.
I post form works and sometimes can only compose half a thought everty 5-15 minutes , Sorry03-03-09 08:41 AMLike 0 - I need someone else to do this to be sure it's not just me. But, have you ever tried to put your Storm flat on a couch or a surface that's not grounded and then tried to use the screen on the Storm. It won't work. The only way to get it to work is if you use another finger and touch the back metal door and then it works fine. I'm wondering if there's some kind of grounding needed in order for the screen to function properly to touch. Just never noticed this before.
Since its plastic, I thought my Arkon mount might have a static charge. Your couch might have a charge too. Such a charge might effectively "blind" my storms touch screen. When I get the ambition, I'm going to try spraying my mount with static guard to see if that resolves the issue.03-03-09 09:06 AMLike 0 - Whenever I am charging my Storm, it is normally laying flat on the desk. The desk is made of wood, so conductivity is minimal. My chair is mainly leather and wood, so I don't think will conduct a whole lot either. If I have to use my Storm at that time, I will keep the phone on the desk. And I don't have any performance issue. I also tried not to touch the casing of the phone and touched the phone with one finger only. And Still, it worked just fine. I wonder if it is because of my "electrified" personality? ha ha. =)

If nothing is selected, then the click won't work either because they work hand in hand. Also, trying to click on a soft background could cause the click to not register sometimes (depends on how hard you press), not exactly what this is about, but thanks anyway.03-03-09 09:43 AMLike 0

tested it out lying flat on any surface, hard, soft, it didn't matter. What mattered was to get the touch screen to work I had to:
1 - place my finger (lightly) on the back and then the touch screen would become responsive
2 - have the phone plugged into a power supply (i.e. USB or wall/car charger). The touch screen would become predictable again.
My lower buttons, phone, home, return and end would always work, but never the touch screen unless one of the 2 above conditions were met.03-03-09 03:20 PMLike 0 - JRSCCivic, I am on 0.76 (yes, I know, old but dependable). I noticed this a while back when I would use the phone in my Bracketron car mount. I then

Weird...03-03-09 04:13 PMLike 0

- These comments refer ONLY to while charging. Later this evening I will report on while not charging. I have not tweaked my mounting screws and I run 4.7.0.75. However, I have finally inserted a nickel-sized felt pad (maybe a dime in thickness) in the center of my phone on its inside cover.
While charging it flat, it works nominally with no hesitations.
(I did read about somebody saying that their Storm's ringing sequence is altered when flat. I don' t agree or disagree. I have always assumed that VZN controls this sequence.)
Well, after finishing up charging and waiting like 30 minutes, I lay my Storm flat and...it worked nominally with no
hesitations - that is, AFTER coaxing it into portrait view. (No amount of screaming or magic incantations while it was
lying flat seemed to make it go from landscape to portrait view - only picking it up, getting it into portrait view, and then
carefully lying it flat still in portrait view worked!)
