Pressure Sensitive Digitizer - Asus Eee Pad Transformer Prime

Have there been any reviews on the digitizer for note taking? I had read that the digitizer had a pressure sensitive display for note taking/handwriting but I can't find any reviews about it.

I'm pretty sure there is no active digitizer on the Prime, just a standard multi-touch capacitive touch screen. If you have a look at the following Youtube video (starting at 2:35), there's a demonstration of SuperNote which is the same note-taking app that came bundled on the original transformer in later firmware updates.

[Q] best small tip stylus?

What is the best stylus for the capacitive screen we have? I am looking for something with a fine point, let me know your opinions, thanks in advance!
Not how capacitive screens work
That's not how capacitive screens work. No matter how fine a stylus is, the screen will recognize the same thing. This is because a capacitive screen does not measure based on pressure, it measures based on current (At least, that's what I've been told).
If you wanted a finer tip to do finer things with,I'd go for an active digitizer display or resistive screen based phone (Which are basically obsolete now due to active digitizers and capacitive displays.
Hope that helps a bit.

Yes it is true that capacitive detects current instead of touch, that does not mean that it is less accurate when discussing location of touch. The underlying grid determines this, but in todays screens, I would think it is as accurate as a resistive screen.

thank you but i am not looking to exchange this phone for a resistive phone, so given this new information, what is the most accurate stylus that isn't too thick
I was looking for the exact same thing, and ended up going with the "Newest Generation Slim Capacitive Stylus" by A Young Life (AYL). Got it off Amazon, but it might be available elsewhere as well. Works great, slides with minor resistance, and has a much narrower tip than other pens I've used.
While point width doesn't make much of a technical difference, it certainly affects usability. All capacitive stylus models I've seen use a round tip, and the point of contact at the bottom of that little semispherical nub is what registers as a touch on the screen. No matter the size, a sphere is going to converge to a single contact point (with a little give due to material and pressure). But, since you can't see through the pen, you have to estimate the center of the nub when touching it to the screen. The smaller the blind spot created by the nub, the smaller the margin of error.
I bought one off Ebay for .99 delivered from China. It's a small cute collapsable pen with a thin point. I haven't tried it yet because while the tip is thin to allow precise pointing, it is also made from a hard material and I'm scared it may scratch the screen. Is that possible?
If the tip is made for capacitive screens, it should not harm the Atrix gorilla glass.
Could anything sold for under a buck from China possibly harm....Anything?
Youbetcha. As Bush and Mao both said "Trust but verify". Even a gen-you-whine Palm stylus could scrtach Palm screens, so why trust the cheapest stuff from a no-name vendor in China to be any better?
Put on a screen protector first, much cheaper than replacing the screen.

I just received the one armathrillo is describing a couple posts back and I've got to say this thing is nice. The tip is actually a soft hollow bubble. You couldn't scratch a screen if you tried. It's nice and heavy but not too heavy. It feels like a nice solid pen. The little lanyard attachment is a nice touch. It detaches from the stylus and plugs into a 3.5mm headphone jack for storage. when you're done with the stylus just clip it on and the pen stays with the phone/tab/pad.
i know this is old, but I just recently heard about the jot stylus which seems to be fine point...

Stylus Problems

I've tried 4 different Capacitive Screen styluses on my Tablet S, with no screen protector, and it requires me to push much harder than on any other tablet or screen I've tried it on.
Can anyone test this out on their Tablet S for me?
Is this normal? Or is this just a defect in the one I got? Give it a try and let me know please.
Ive never tried a stylus on any other tablet than the Sony one I own so I didn't know it was just an issue on this one but yes, the performance of the stylus is horrible.
The stylus didn't work very well for me either. The Nook color I have also didn't work very well. Pretty sure the capacitive touchscreens work differently between iOS and android so this may just be a "designed for ipad" kind of issue.
The problem I have is that I used it on the Xoom and ALL the other tablets they had over at Best Buy on display, and they worked flawlessly. Some of then better than it did on the iPads on display :-( damn it SONY, I think it's just a screen sensitivity thing... if anyone figures out how to increase this, let me know.
Why do you need a stylus anyway? If you really do need a stylus, you should have gotten a tablet that supports an active stylus by either Wacom or N-Trig for actual precision, and quality when writing. I know at least the HTC Flyer and one of the Lenovo tablets support this.

Hi,
A friend of mine recommended the Griffin Stylus, although he has an iPad2 he said that after trial and error with several brands, this one was near perfect.
I'm also looking into this, so that I can use the tablet as a notepad for classes - I have the apps installed already, all I have to do now is find the proper stylus.
Dunno if you guys didnt realize that there is a factory installed screen protector over the glass ( yes glass, mineral glass in fact). thats causing sensitivity issues.
If you read the manual it will tell you NOT to use a stylus. The Tablet S is not meant for anything other than your finger tip.

Not according to the link below
http://store.sony.com/webapp/wcs/st...10151&langId=-1&productId=8198552921666381663
I searched all the leaflets and booklets that came with the tablet and could not find any evidence supporting your claim, I also went online to the Sony Forums and nothing about Stylus Pen issues - but it's still possible, as stated, that due to design/build characteristics, stylus pens work badly with the tablet.
So far, according even to my friend's experience on the iPad and the information at the Sony Store, I'm still hoping that maybe the Sony Tablet is just picky when it comes to Stylus Pens and we just have to do our homework before buying one.
I hope that's the case, as I'm planning on using this device for classes and so far, software-wise I'm all set, so all I need now is a suitable stylus pen to write with.
I'll let you know how it goes, but please if anyone else has any successful results on this, please share as well.
Hi, Maybe I am "mis-remembering" it. I believe if you click on the Sony Help Icon it will take you to a website with various tips and information. In there it will tell you not to use anything on the screen except for your finger tips. I should confirm this for you but I am tired and lazy. Anyways, I don't see the point in using a stylus with this tablet. To me, this is the kind of tablet you leave beside the couch or your bed. In my opinion it's not a travel / work tablet.

Couldn't disagree more, this tablet keeps surprising me, in a positive way.
Work is always relative, travel is just not so as this seems more and more as THE partner to have, but opinions come and go, of course.
As for facts, check the image below - and hopefully the stylus drama dies here.

I'm still to put the screen protector, will report back as it is done.

I picked up the Griffin stylus GC16040 and it isn't working well with mine with the Sony screen protector on. I still had to give in a good amount of pressure for it to work.
Has anyone tried the stylus sold on the Sony store website?
I'm going to assume it'll work because Sony is selling it, and it says specifically that it is for Sony tablets. I'm going to place an order to try it out.

I got my screen protector from amazon today - not the official sony one, and another set of stylus pens - Groov-e, GV-CP2
Both stylus packs work ok, but with screen protector I do have to apply some little pressure, but I have to say that for me, it's basically the same as when writing with normal pen and paper...
I do notice a slightly more diffuse image due to the protector, and the griffin stylus is alot softer to use than the Groov-e ones.
Both work ok, but the Groov-e just seemed slightly rougher, when typing I get a subtle scraping sound...
I also noticed that not all apps behave the same with this, personally I liked genie writing best, whereas hand writing HD didn't feel so precise in capturing my strokes.
Sample 2 in attach.

Which screen protector did you get exactly?
Drawing in supernote is the same with your finger or stylus, not great. It misses some inputs when drawing. I'm sure with future updates it will get better. I'm using a targus stylus.

Stylus on Sony Tablet S
I bought these TOUCH SCREEN STYLUS FOR Huawei IDEOS S7 Slim Tablet
on ebay and tested them on my Sony Tablet S and Galaxy S phone.
It works 100x better on my galaxy s phone than on the sony tablet.
They do work on the sony but the sensitivity isn't there, a fair amount of pressure is needed in order for it to respond.
I'm also interested to see if anyone else gets a better result with the targus stylus that sony sells.
I created a short video to show the problem. Go to youtube and search for AntMoore23, go on my channel and watch.
I think for the Sony it has a special resin that allows the screen to have a better black response. I think maybe that's the reason why the stylus response is bad. Just something to keep in mind.
I use a griffin stylus (GC17125) with sketchbook pro every day and it work just fine.
I also tried to build my own stylus with a sponge and some other crap (try a search on youtube) but without success.
did anyone try using the Stylus used in the video here, they call it a Wacom Active Digitizer
http://youtu.be/oty4ukjSIjg
The active digitizer is not the stylus, it's part of the screen technology inside the tablet, similar to the Galaxy Note.

Touch screen responsiveness enquiry to those who have the Prime

I have seen multiple mentions about Prime's touch screen requiring 'stronger touches' to react. Is that true?
I would like to use the tablet for sketching, which is done with capacitive pens (like the one made for iPad 2 by Bamboo) which have a sort of an 'air pad' on the tip, making every brush quite light. Does anyone have such a pen and has tried it on a Prime?
It will be frustrating if I cannot use the pen at all if Prime does not react to the less-prominent touches. I also prefer light touches for actions such as swiping across the screen in galleries or on Google Maps instead of making the swipe very prominent.
If you have Prime, could you share your touch-screen experiences with it?
Or is there a video that demo's Prime touch screen with a multitouch app with varying touch stroke strengths? If you have the Prime, could you record such a video? I am sure many would appreciate it
I dont have a pen but it seems that sometimes it takes a harder touch to select anything on the home screen but for.example when im using the browser a very light touch will scroll just fine
Sent from my Transformer Prime TF201 using Tapatalk
yeah i'm interested in that point to. I have the Bamboo stylus but not the prime.
Asus stated that the touch screen was more responsive (faster) than the average Android tablet and I 'd love to see how that goes compare to say...the original Transformer !
I get my tab tomorrow I have like 3 different stylus I can test out.
Got a rocketfish stylus, cosmonaut, and a dagi. (hoping to get an adonit jot soon too)

Do any of them have an air-pad type of build? Bamboo stylus looks like an 'eraser' from one end, but it is actually an air-pad of sorts, so it is very light. I know that many capacitive pens are like less-friction erasers, completely filled. These are easier to make taps with on less-responsive screens. But they are not as smooth and light for writing naturally.
I am especially interested in the air-pad type of capacitive pens like the Bamboo is, since they are better for sketching and natural handwriting. I wonder if such pens have issues with Prime (they work perfectly on iPad 2 which reacts very well to light brushes).
The cosmonaut and the rocket fish are both air pad type

Great! Do let us know how they perform, it will play a huge role in my decision whether to buy the device or not.
I hope it works well with my Jot Pro stylus, too. It's really nice on a borrowed iPad 2.
my jot pro is coming today so i can report back then.
but as another poster said, some times selecting items seems to take a harder press than my xoom did but scroll in the opera browser is almost too senstive.. the slightest touch scrolls the browser..
i think you will be fine with your pen.
My touch screen is very responsive I feel no need for a stylus but it wouldn't hurt
I don't have a pen device, but can give a point of comparison...
The touch screen on the Prime is much less sensitive than the one on my Xoom. I wouldn't call it bad, but I definitely have to press harder to register inputs.
Jason
my touchscreen seems very responsive. seeing this thread made me back out n test it again. on my prime, the slightest touch barely touching screen will have it scrolling up, down, left, or right very smoothly. I mean literally the slightest touch and the prime will react. I have a capacitve pen also that I used sometimes on my Ipad for drawing apps like Sketchbook n such. I can't remember the brand of pen. I think its the Targas one. I bought it at best buy when they had their sale on them for cheap. the end of pen is more like half a spongy rubber ball of sorts. if you press it too hard against screen it'll mash down end of tip. so end of my pen tip is not solid. more like hollow rubber end that flexes with pressure. I haven't tried it out on my prime yet. I will though after seeing this thread.
That's weird..Do someone have the original transformer and could give us a comparaison between it and the prime, maybe in a touch screen test apps (wich should not be limited in speed by the software optimisation)
I was looking forward to what Asus called a faster responding touch screen but it seems like they forgot about this one. Or maybe the xoom was very fast. Or it's a software thing or it needs more indepth test to tell
The thing is, I don't NEED a stylus but I'm using one to draw in sketchbook and it's already not always perfect on the Transformer (still good though) but I wouldn't want it to be even less sensitive. It's hard to draw correctly when you have to press the screen like a mad men.
When I first got my prime, I had issues with the touch screen. Typing was especially a pain because it wasn't recognizing key presses. I then used the cleaning cloth that it came with and cleaned the screen really well. Since then I've had no problems.
I'm guessing that the protective plastic left a film.

The firmware updates helped alot too
The cosmonaut words terribly with the prime.
The rockfish works pretty good when writing, but for delicate touches when drawing it its a bit jittery. Looks like I'm making dotted line instead of solid lines. Needs a fair amount of pressure, but not super hard.
However when using fingers to draw even light touches work great.
Waiting on funds to get a adonit jot pro bc I hear that is the best stylus

No it will connect to the Prime via Bluetooth, thus allowing for pressure sensitivity and greater precision. The buttons are for the app devs to implement so that you can change from things like pen to eraser to marker without going in manually.

if its actually shown to improve accuracy on the prime's digitizer id spring for one, but not until i can see some actual screen tests
I liked the video.. People using their iPad to draw etc. It's a nice concept.. Not sure how much other use I would have for one.. I bought a prime with a keyboard because my handwriting is so bad!
Really want to know if it would work well on TF201. I am looking for something i actually can write some notes on the pad. It is what the pad is missing now for me
I don't see the point unless ASUS fix the wavy diagonal line issues. What good is a pressure sensitive pen if I can't even draw a straight line with it or any stylus?

This is using antipaper and my finger.. Running on AndroWook 2.1 on my tf201
The Jot Touch won't improve the accuracy of the TF Prime's digitizer. It uses the standard Jot Classic tips therefore it will be just about as accurate as the Jot Classic stylus. It does introduce a pressure sensitive switch and bluetooth in order to relay pressure information to applications that can read it but these won't have any impact on overall accuracy of the drawn lines.
TL;DR: The Jot Touch won't be more accurate than any other capacitive stylus on the Prime, but it will have pressure sensitivity for those apps that can make use of it.

LCD replacement?

First, I am not sure the LCD can be replaced individually from the digitizer or if it just my disintegrated LCD that indicates this.
Anyone that know the LCD type in the TS?
Is it LH154Q01-TD01, LG display supposedly in iPad Nano gen 6, found on AliExpress starting from $7.50.
The product number on the back of the screen is partially lost: xxxxx820-V6A44046x
My screen is toasted, looks like this:
http://forum.xda-developers.com/showpost.php?p=51140410&postcount=10
I have used the TS when running, no submerging. . The screen started tearing. I opened it and tried to save it with electronic cleaner. Marginally less sparkling, but the cleaning solution is seen now.
The LCD was dissolved by the cleaner so dismantling and cleaning did not improve...
All kind of expected...
The Alu version is usable after KitKat update. I cannot really motivate replacement in time and the waterproofing is hardly better after this. So $7.50 is probably a questionable investment, I have to file this under "unmotivated expenses".
Or should I get a real training watch instead?
