Capacitive screen works with stylus-like objects? - Optimus One, P500, V General

I've discovered that my Optimus One screen responds to pens, pen lids, fingernails and other random objects. This makes no sense to me as doesn't a capacitive screen need a conductor such as human finger to operate. Or is LG just being dodgy?

hammers fix everything. sometimes permanently.
I got similar results from a homemade stylus (using a metal pen holding a saltwater-wetted tiny piece of sponge wrapped in a piece of a thin grocery store style plastic bag) and a cheap commercial stylus with conductive rubber at the end.
I thought that something was wrong with the homemade since I had to press hard to get it to work and it wouldn't slide well, but the commercial model has the same problems.
Also had things like wet towel activate the screen, but my woman complains that the screen doesn't respond to fingernails (not mine or hers) and she prefers the older resistive touchscreen type.

So it doesnt work with anyone else's fingernail either?

I know from the LG GT540 device (i have had that thing before my P500) you can use
both finger and finger nails - but its nothing for me, sometimes the display doesnt responds correctly.

I had the swift, official legend of a device now,
and I've had it work with a t-shirt will wiping the screen and if it rains and the is a little water it i'snt as precise

capacitive stylus?

Has anyone tried the capacitive stylus from Boxwave? I've used a Palm for years, and find I miss the stylus. So, anyone????
I'll probably buy one this week, unless someone else has made the experiment
If so, I'll report back. Amazon has 2 versions, regular and mini. The mini even has a cute little tether that plugs into the headphone jack.

I am curious if this would work. I kinda dont think so, but I dont know much about if there is anything inside a stylus to make it be recognized by a touch screen. If it is just plastic then doubt it will work.
Capacitive stylii (I'm thinking that's right, but I really don't care ) have a method of conducting electricity from the hand to the screen. Most are made of metal and have a conductive foam tip that transfers the current to the screen as your finger would.
Any *capacitive* stylus should work fine on the Slide's screen assuming you're directly holding the stylus (so no gloves in the winter).
I thought they used magnets to produce a magnetic field.... Didn't think about something to conduct from the hand tru the tip... Very interesting.

i heard something about using a wienie (sorry if misspelled) as a stylus on capacitive screens works. just that it'll make your hand and phone smell like wienie.
ive used it but i still prefer my fingers

Yeah, I read about the hot dog stylus and using anti static plastic (from a hard drive, ram, or video card, etc. (Sensitive computer parts are wrapped in) rolled up in a stick formation. I guess you could wrap a pencil in the stuff too. But heck, mini styluses are sold for $5 and up to $30 for a high end model. None work perfectly, I hear. I might try a mid range model for 15-20 and see how they are...

[Q] Decreased screen response with official Malata Case

Hello all,
I purchased an M1 Official Malata Case for my Gtab. I ordered it from it2steve, received it yesterday and it looks and fits great.
One problem...
It now seems that my screen is less responsive. I specifically notice it around the corners and around the right edge (same edge as home keys). Its becoming a problem with ADW as it is difficult to hit the onscreen button to open the program launcher and difficult to hit the Home button located at the top taskbar.
When I take the tablet out of the case there does not seem to be a problem. I have tried recalibrating using the took by gojimi and it does not seem to make a difference. I also have a Skinomi screen protector on, which I do feel had reduced the response already slightly, but it is now much worse with the case. I am also running Vegan 5.11.
Let me know what you think.
Maybe,Magnet will affect the capacitive touch screen.
I have noticed that the right hand side of my screen is a bit less sensitive than the left, but I had not associated that with the use of the case. (I have an m1 case as well). I also remember this being mentioned in another forum by a frequent contributor here.. (the lack of sensitivity, not its associated with the case).
It is a bit annoying to have to hit a button twice (and sometimes messes me up in angry birds) but it is not that severe in my case.
Dan
I too have chimed in on a couple of these posts adn I origionally thought it was the case as well, as it just seemed to be in the upper right hand corner. However I still have that issue and noticed last week (when I actually started typing more) that I was having an issue with anothe spot, right around my 'A' key.
I know that this has nothing to do with magnets or the edges of the case as now I'm playing around in the CLIP. I use Gojimi's calibration app but I'm personally leaning more to 'it doesn't like to wake up properly' as it seems to go away when I reboot?
I am pretty sure this is because of the case (to be precise, it is the part that wrap around and infront of the tablet)case.
I have an apad case and had the same problem. My tab has no problem outside of the case.
To solve the problem, I had to cut out the leather part that wrap around the tab and use a piece of velcro to keep the tab inside the case. I had no prolem now.
I am with you steve, that A key gets messed up.. and it does appear to be software, because it appears (my subjective opinion) that you can improve the sensitivity by doing simple things like hiding and exposing the keyboard. It also seems to be different depending on what you are doing.. for example, you would think that if it were a dead spot on the touchscreen, it would interfere with typing when you held it vertically, but it does not seem to.
BTW, is the clip case any good? I am debating whether to buy a dock from you
Dan
Maybe its just me but since i've received my M1... which i love. My touch screen seems too sensitive... i'm click stuff when its suppose to be scrolling... I'm going to say its not the case... Because my is doing the exact opposite.
on a side note when i originally got my gtab sensitivity was awful... i switched to the gingerbread rom and it seemed to fix itself.
All the more reason for making the switch once it pops into Beta!
I have one of the M1 cases and the Skinomi screen protector and just did some tests with and without the case. I can not discern any difference at all when the case is on.
The main problem is that your fingertip is less compatible than your finger pad due to calluses, etc... With the case on you cannot get a clean shot at the extreme most corners. You can only hit it with your fingertip. This will vary by person. A construction worker will have a harder time than a surgeon. When you take it out of the case, you are hitting the area square with your whole pad.
Is anybody else still experiencing this with the M1 case? I'm trying to decide between the M1, P3 and the Clip and decreased screen response would be a huge deal breaker for me.

Yea, I did but not sure I totally follow what you're saying. Why would a person use only fingertips with a case as opposed to their whole finger pad without one?

The case is not flush against the device. On the edges where it covers the screen there is an ever-so-slight upward curve (just the nature of dealing with this material). So, when you try to press the edge of the screen where it meets the edge of the case your finger is partially blocked by the case. That means that sometimes only the tip of your finger makes contact and sometimes that is not enough to trigger the action you desire. So, I think people were experiencing this occasional malfunction and blaming it on the case. The case is sort-of to blame, but it does not reduce screen sensitivity.
Do that make more sense?

Yea, I think I got it. Thanks for the clarification.
Maybe I'll opt for the Clip since it doesn't seem to cover any of the screen.

I am looking to do the same, eventually. However, even if I didn't buy the M1, I still can't justify $50 for a case. That is almost the price of 2 M1's.
Yea, the price is making me think twice about it.

Accessories for N2E

Placeholder post!!
Well, there is not much on accessories side for Nook STR. Cover, screen protector, external light and SD cards.
I'll stick with my cheapo cover from amazon.

Jrec,
The cover is the Casecrown one. Was cheaper a couple of weeks ago. It fits snuggly, blocks only SD cover, and it makes a little harder to hit the button savior arrow on the right side. Besides that, a winner.
Casecrown cover
Thanks! I trust that in time we'll see lots more after market stuff for the N2E.

A Great Light For N2E...
I just bought the Kandle Ozeri II light for my N2E it works great. Amazon has it for $25.00 (not able to post links yet). It runs on the button batteries two for 20 hours. At first I was against this but you can by 25 for $5 on Amazon. It also has two settings for brightness however the lowest setting works great for me with no dark spots on the screen. Some of the reviews stated it looked cheap and some of the clips have broken on them. Mine seems good so far but I'm careful putting it on and taking it off.
Mine even goes on with the nook cover (Lautner Case) I just got at Barnes. When I slide the light on I still put the clip in between the cover and the back of the device. But I think it would fit over the case also.
Also one more thing it does block the power button when you clip it on top of the N2E but I turn my device on before I stick the light on.
Hi,
Has anyone insights about stylus ? (cf. "Simple-Touch-Reader-Generation-Accessories" on Amazon)
Thx !
Have a Verso Arc Rechargeable reading light, and it fits perfectly on my nook.
USB keyboard
Would love to buy a working USB keyboard/dock, once it exists.

There will not be a stylus for the Nook STR that will offer any sort of precision because of the IR touchscreen. IR touchscreens aren't extremely accurate and require a large contact area on the screen to reliably pick up the touch. It's not capacitive, so a capacitive stylus won't do you any good, and neither will a typical stylus for a DS or palm or other device sporting a resistive touchscreen (resistive touchscreens can essentially be poked with anything and that anything can be used as a stylus)
Simply put, it's because of the IR touchscreen needing such a big contact area that you're not going to see any effective stylus, ever.
However, a finger and a whiteboard widget does result in an effective notepad.

I picked up an iFrogz stylus from Staples for my phone it works great on the Touch too. It's got a soft tip so it's not going to mess with the screen and it's accurate enough to work or write with.
I use the rubber on the end of a pencil to hit chromium browser tabs while in vncviewer... seeing as it's not a capacitive screen
rather good...

Magic pen upside down

Hey, have I just noticed this last night. If you use the top of the magic pen on the screen, it works just like your finger does. More specifically, it works like a capacitive stylus would! This wasn't advertised as a feature, was it? If not, I'm glad I figured it out. It makes it so I only have to use my fingers sporadically.

It's an old trick to use the negative side of a battery on a capacitive screen for a makeshift stylus. Since the negative side of the battery is cap side, it takes advantage of said trick.

Actually it has nothing to do with a battery..
It's just a metal conductor touching your fingers with a large contact area, you could use a frozen sausage!
Use the back of a teaspoon on the screen and it works just as well!
Take care though, the metal can easily scratch the screen.
Best thing to do is attach a small piece of conductive foam (the soft black kind that delicate IC's are sold in) to the top of the pen.

I will somewhat disagree.
While the pen may act as a conductor, holding the pen with a pair of insulated pliers and using it upside down also works. Thus, it is the battery as well
Sometimes I shouldn't be allowed to play with stuff when I get bored.
Regardless, it is a neat unintended feature

Agreed, it will work this way due to negative charge on capacitive coupling but we always look at MISS (Make it simple, stupid!)
If i can explain to readers, a better use of their pen with a nice bit of conductive foam on the top (EVEN if the battery is missing or completely flat) then that is the best option in my opinion, no need for confrontation.
Oh, BTW, your choice of pliers will have an effect on your experiment! If they have any metal content, the capacitive coupling pick-up from your hand is increased, just try it with non-conductive plastic tweezers/forceps and it won't work... We ain't talkin miiliamps here, were talkin nanoamps...

Neat that those things work and all, but how cumbersome is it to use
some hulking monstrosity as a makeshift stylus that is intended to be used for delicate/precise touches such as drawing? Wrap a leaf blower in foil and connect that to 300 feet of copper wire which is spun around your body and leave a length of wire as long as your finger coming off the top of your hand and you don't even have to hold it!

Yep this is a little old-- New news is that when Honeycomb drops it's supposed to have support for the pen tip to be used as the stylus.

Fingerprint reader sucks when wet

Anyone else come from another phone such as the LG v20? I noticed the fingerprint reader on the LG v20 was much better when wet. At least with the lgv20 I could unlock my phone but with this phone it does not respond at all forcing me to use the power button and my unlock pattern.
Even the smallest amount of water or wet finger makes it not respond.
Yes wet fingers and also cold weather seem to affect fingerprint readers on lots of devices. Usually I can rub my finger back and forth on my shirt for a while to get the friction to sufficiently dry it.
Right. Little wet and it doesn't work.Not big of a deal for me though.
My LG V20 would work when wet. The Samsung doesn't even want to work even after I seemed to have dried my finger. It pretty much wants nothing to do with a rainy day.
