Stylus not working on part of the screen - Eee Pad Transformer Accessories

hey,
i bought a stylus to take notes on the transformer but it's not working on the hole screen.
i have attached a screenshot for demonstration.
does someone have an explanation for this phenomenon?
EDIT:
i just wanted to prove it works perfectly with fingers, but i found out it doesn'!
see the screenshot draw_thumb.jpg, i actually wanted to draw straight lines and one circle.
btw, his is the same in ubuntu and android!
EDIT2:
updated screenshot
EDIT3:
i restored everything to stock, and like i was afraid the problem persists.
i have to return it.

Looks like some sort of grounding issue. I know the Evo 4G had issues like that on its earlier 2.1 versions. If you hold the tablet in your hands and try to use the stylus on the bottom half of the screen does it still not register?

i retried it, and it really seems to be a dead-part in the touchscreen
is there any chance this is a software issue?

Got a lemon?

Haven't really seen any posts on this, so maybe I just got a lemon...
Got my Flyer last night and first thing I noticed was that I had some light-bleed at the bottom of the screen in portait mode. 2 greenish blobs to be exact. Also some more slight bleed along the right side from top to bottom. I cranked up the brightness to just how bad it was, and lo and behold, found 3 stuck pixels.
Examined it a bit more and noticed a slight gap with light passing through along the bottom edge, where the screen meets the bezel. And last but not least, also a jaggy scratch on the aluminum itself.
I'm going to take back to BB and exchange for another, was wondering if anyone else had flaws like these? HTC build quality is usually pretty good, so I was surpised to see this on mine.

There seems to be some different issues depending on which version people have bought (EU/US/other, Wifi only/3G+Wifi).
I have EU 3G+Wifi,32GB version, my screen and the exterior was perfect, but the touch sensors are totally irratic. Sometimes the far most left edge doesn't respond in portrait mode, some times it seems to respond to nothing at all, just flicking the home screens around, pulling the status bar down, launching shortcuts, or typing random stuff, even the soft keys are buzzing and active when this happens.
It actually did this from the first time I powered it on, and it took me 30 mins to get through the first few steps to get it up an running because it kept pressing the wrong places and quite often hitting the back soft key. I tried a factory reset, it helped slightly, tried recalibrating the keyboard, tried various hacks found around these forums, nothing helped. It seems worse in landscape mode than portrait.
I am getting it replaced by Amazon, which is quite nice since it also seems to acquire scratches very easily, even using the capacitive end of the pen has left tiny tiny marks. So, I ordered some screen protectors just to be on the safe side.
No issues with mine, sounds like you just got a dud.
No issues with my and is 16 gb wifii
Ok, just exchanged and got my 2nd one at a different BB... more problems.
This one also has some light-bleed at the bottom, but not as bad as the 1st one. Also has 2 stuck pixels, you can see them perfectly using one of those screen tester apps. And lastly, the volume rocker is loose, when I pick up the tablet, it makes a rattling sound.
Also weird, when I first booted up, had a default wallpaper of a blue skateboarding Android on a dark background... was not the normal default HTC wallpaper, wtf? lol. The box was sealed shut, had never been opened. Weird.
So back to the store again tomorrow, gonna exchange.
Edit: Tried out one of those stuck pixel fixer apps and didn't work. The stuck pixel is red, can see it perfectly on a dark background. I'd be willing to keep this one despite that, but the loose rattling vol rocker is driving me nuts. Argghh!
Ok, I guess 3rd time's a charm because I got Flyer #3 today and seems to be perfect - no dead/stuck pixels or rattling vol rocker! Everything seems solid.
Interestingly, on #1 and #2, the 3d carousel effect never worked at all. But on this one it works fine. Really surprised I had to go through 2 bum units first to finally get one that wasn't defective..

wavy lines

I am an artist, who loved sketching on his ipad, but had to sell that one cuz of its restrictions being apple ..
Now I have an Galaxy tab 10.1 gt 7500 ..
But I seem to get those ugly wavy lines when ever I try to draw diagonal lines
The slower I draw the more wavy they become.
But if I draw it in a quick gesture, it does not show any problems
Have put up a screen grab of me drawing straight lines in Sketchbook Pro
( this problem happens even in other Drawing Apps )
Please do help
Cheers
I checked on mine (in sketchbook) and it works fine. I'd guess there's something wrong with the touchscreen. If it's new, I'd go exchange it, or get warranty service.
I, too have used this app and don't notice wavy lines like that, unless I want wavy ones. I usually use a tablet stylus or brush instead of my finger.
same problems
got a new replacement , yet the problem persists. Drawing with a capacitive stylus too does not give accurate results
Also when taking notes, a lot of words and letters get skipped and the letters dont come out fully
Any of you guys actually use this for note taking ?
Is there any solution ,workaround for this digitiser inaccuracy ?

There's a thread in the apps and theming section that has a list of compatible widgets and apps that work on our tabs. Look for SuperNote. It's perfect for taking notes. For your drawing problems, maybe it's the type of stylus you are using. I have one from Samsung with a rubber tip that works great. I also use a nomad brush for more realistic brush strokes and feel that works great.

The super note app is great !
Its got a faster response time ,
Though is it possible for you to just post a screenshot of you drawing diagonals or circles slowly using a stylus , just want too see if the batch of tablets in the store are having problems
Ok, I've got exactly the same problem!
I guess most ppl won't notice this until they try to actually draw something.
Any luck finding solution?

Ok, I tested the stylus on friend's htc desire - same thing. Using finger does not produce waves, at least not that big.
Looks like the problem is related to the contact spot size, small spot - problem.
I guess the problem is the interpolation between the sensors.
I dont know if anything can be done here... But if someone has an idea, please share it!

Stylus marking too early

Hey, I'm currently on HC for the Flyer and having trouble with my stylus. It'll start writing/marking the page when its about 2-3mm above the screen. This is pretty annoying since thats my natural holding position. Is there something I'm missing?

Your stylus must have a stuck tip, because it isnt supposed to write until you put pressure on it. In fact I can move my stylus on the screen and it wont mark it unless I apply slight pressure.

Try replacing the battery. I've seen other threads where this behavior was associated with drained batteries.
I had this happen too. It occurred shortly after I installed Quil with the Lenovo app mod I don't know for sure if it was a strange combination of the two or the maybe a stuck pen. All I know is that I did cleared the data, caches (a hard reset if you will) and then reinstalled everything but Quill and I no longer had an issue.
My stylus has a same problem.
It has occured since I bought my flyer.There is always same problem on stock GB, stock HC, cool3D HC, and leedroid HC.
It seems to occurs especially when my hand attatch on the screen...but I'm not sure.
Because of this problem, I can't use non-pen pressure app like tabnotes
Quill is better to use because there is pen prrssure so that stroke is narrow and faint when I can draw a few milimeters above the screen.
Sent from my HTC Desire using XDA App
I have also had this issue and it seems to clear when I hold the erase button and clear the markings made when 2-3mm above the screen. After that it seems to work normally again. That's just in the Notes app, haven't come across the problem anywhere else.
Hi all!
Please tell me who know....!
Htc Scribe Digital Pen D500 (from Flyer) is compatible with the HTC Evo View 4G ???
I remember when I had this issue, someone in the apps thread advised me to try using the stylus with the buttons facing up. I haven't had a problem since.

Anyone having issues with unintentional S-pen actions

Picked up my Note on Sunday from Best Buy. Yesterday afternoon I started having problems with S-pen causing inadvertent actions without me touching the screen. At first I thought maybe I touched the screen without realizing it, but at this point I can hold the pen 1/4 inch or more away from the screen and it still occasionally clicks the screen (or draws a line in S Note). Not constant, but often enough to be easily demonstrated.
I'm planning to exchange it but wondered if anyone else is having this issue or knows of a fix.
Digitizer performance continued to deteriorate over the next few hours and using the S-pen became nearly impossible. It was clicking everything it came close to. Did a factory reset to clear any software issues but the problem persisted.
Best Buy staff was great about exchanging the phone... and I got the last blue Note they had in stock. I was surprised they still had their one white Note available; no one had bought a white Note at that store.
Yeah I noticed that on mine. It lasted a short time but was pretty bad.
This is rather unbelievable as it's a Wacom digitizer not some Samsung hack, in spite of the S-pen moniker.
I imagine it's possible Wacom didn't want their name associated with it just because of something like this. I hope not at least
Anyway, I never noticed this with the international version, and I had one for a while.
Unacceptable if it would occur often.
update: It just occurred to me that this may be a pen issue. It's an ultra small pen, and this issue might not happen with a regular Wacom pen.
I will keep an eye out for this.
Not just S pen
I'm experiencing the same issue with my galaxy note, but not just with the S pen.
After upgrading my software, the lower-right hand side of the screen just went dead every time the note was placed on a flat surface. very annoying issue.
I was forced to downgrade my software just to get it working right again. the thread regarding this issue can be found here:

touch issues

Im so frustrated by the touch screen on my ZU, its so Sensitive (or under Sensitive ) that i always accidentally select items or make phone calls when i scroll through lists. I've updated to latest firmware already but same thing
Is no one else experiencing this? I only see a complaint occasionally. I brought the phone to Sony of Taiwan and they said it seems normal and dont recommend i send it in for repair.

Things like this are always a double edged sword.
On 1 hand people will see this as an issue and dislike it, or others like myself will like it as it makes the screen effortless to interact with.
I can see your point though, especially if you are coming from a device with a screen not as sensitive.
I come from an iphone, and have played extensively with a S 3,none of which have these issues,and are just as effortless

I had this problem with the Sony Tablet Z and it drove me crazy.. a software update fixed the issue but I returned the tablet anyways. But I have seen no issues like that with my Ultra Z.
Yup, updated this morning hoping for a fix but seems the same. ..trying to do factory restore right now to see if that helps
.475 seemed to have fixed that issue on my phone.

A factory reset DID help ! The touch still has occasional issues but much better now ... Finally can use the phone properly
Sorry, it didn't help. problem still exists and Sony is telling me this is acting as suggested. I guess I'll have to wait for someone (hopefully) come up with a sensitivity adjustment.
Did you apply any screen protector as certain bad screen protector will affected the sensitive issue.
Other wise, did you a iPhone ex owner. No biased on this, but base on what I had seen so far, certain iPhone owner can't proper use Android phone due to the touch & scroll method is different. Android only need to slightly touch not like iPhone need much pressure on it.
I've removed the screen protector, same thing.
It can't be an iphone vs android thing, the problem doesn't exist on Samsung devices I've played with or my Nexus 7.
It feels more like the screen is not sensitive enough? It isn't registering that I am still scrolling and so it registers a finger "lift" and selects into an item. Same thing if I try to hold a key on the keyboard to access secondary letter (holding down on a key to select comma, for example) it'll repeat hitting that key. I have to exert a lot more pressure and be very sure my finger doesn't move to properly access the secondary key.

The repeat-hitting when tap-hold is very abnormal. Why your service center didn't recognize that as a problem when they examine it? I think you should request for replacement.
I also had the same problem... touchscreen is a little bit buggy.. but the latest patch did fix a little bit.. but its still there. still far from my ip5 , s3 s4 note 1 note 2... hope they will fix these soon.
I have exactly the same problem on mine, sometimes is really hateful but for sure when rooted we will be able to change that value.
I also have major issues with the screen.
The best way to illustrate the problem is by holding a finger on the screen on the lockscreen.
It just flickers a lot like I'm tapping repeatedly on the screen.
I've updated and factory reset without it fixing anything :/
I was wrong, I still have issues. The newer firmware just made it overall a little "better" but I am going to send it in for repairs...this is ridiculous.

should I wait for next update?
I'm having the same issue with the screen sensitivity. It also skips when using a pencil as a stylus, which is the main reason I bought this phone- to draw and take notes. I don't like amoleds, need pentaband and can't fit anything bigger than the z ultra into my pocket. It has become very annoying, and I'm wondering if I should hold out for the next update or send it in now...I have no backup phone.

I've sent it in yesterday.
The Sony associate said he can see the issue as being "screen more sensitive than usual" but can't promise anything. He said he will demonstrate it to his colleagues as the repair form lists the symptoms vaguely as "screen erraticly jumps" which doesn't describe the problem accurately.
I will know within 2 weeks and post the results here. I am not holding my breath, though, as I think Sony has pointed out that the specialty feature of the ZU using a pencil to control the screen is produced by turning up the sensitivity of the touch screen. Kind of like Samsung Galaxy S4's feature of allowing users to use the touchscreen with gloves on. At least Galaxy users can turn the damn feature off!
Interestingly enough, while in the repair line I met another user who has a ZU and I asked if he had the same issues. He said no, he didn't have that issue at all.
Sony Taiwan sent it back to the repair shop stating they updated it to .475 and there shouldn't be any problems. Problem is, I already had updated it to .475 when I brought it in for repairs. Problem still exists and I have them send it back. If this doesn't improve I can only blame myself....should have bought a samsung!
Apparently Sony Taiwan refuses to offer any fix for this as they stated this "sensitivity" is needed for the pencil stylus feature.
Very unfortunate, very lame.
Anyone want to buy a 2 week old Sony ZU in Taiwan?
