does sapphire have "real" multi-touch hardware? - myTouch 3G, Magic Android Development

someon says:
From what I've heard, the G1 phone doesn't not handle real multi
touch.
When there are several touches, it just indicates all the X and Y
coordinates, but you still don't know to which impact it is connected.
For instance, you can know that there are some impacts with this
coordinates:
X = 5, 10
Y = 5, 10
But from there, you can't decide whether the impacts are at ( 5, 10 )
and ( 10, 5 ) or (5, 5) and (10, 10 ).
You can still use for those limited things ( multi touch zooming ),
but definitively not for everything !
Still from what I've heard, it is a hardware limitation, so it won't
change !!!

that means , If both touches occur simultaneously, a program cannot recognized these two points.
as Dianne Hackborn mentioned multi-touch response latter in the thread, G1/sapphire has diffrent behavior from moto Droid. it seems sapphire has same screen hardware as G1. so does it means, G1/sapphire both not have real multi-touch harware? and what about hero device?

Touch Screen
No the touch screen is multi-touch however to enable it we need some software modding They probably did not enable it due to the fact of more money on htc hero and such. Most touch screens nowadays are multi-touch but have not been enable for reasons or software. However the quote "but definitively not for everything !" is correct in the way of not everything but that depends on the coding and software not the hardware.

You heard wrong. You can get multi-touch on both G1 and Sapphire. I've got Loccy's BetterBrowser from CyanogenMod, and I can zoom in and out with pinching.

it has a capacitive touch screen, which gives it the ability to have multi-touch through the use of software updates. If it had a resistive touch screen, like the Droid Eris does, then it would not be able to support multi-touch

please read my quote carefully, then you know that there has a possible situation:
when two or more touches occured, the screen hardware give out two X-values and two Y-values, but not two pairs of (X, Y).
in this situation, we cannot dermined if X1 are paired with Y1 or paired with Y2, the same X2: paired with Y1 or paired with Y2?
just think about how a capacitive screen works, if the manufactur designed the hardware works as this situation, then we cannot make a multi-touch action with two or more fingers SIMULTANEOUSLY.
so we still has some multi-touch functions, but not all of them.
Dianne Hackborn is a google guy, so i think the difference between our phone and moto Droid must be exists. but I don't know if sapphire or hero falls into the situation above.

hope everyone's views helped (wrote this because I could not delete post)

yeah i am getting confused with the tatto. That one has a resistive touch screen. I just checked up on it.
@xillius200 Though it can have multi touch using stantun's technology, it is too expensive to make it a cost effective phone that people will want to buy and it also makes everything a lot bulkier.

I have an HTC Magic running a Hero ROM and I have multi-touch, but rarely use it. It seems the more features I have the less I use them... including Bluetooth.

Although i agree stantun's current solution is bulky, it could easily be adapted to a mobile platform, with enough interest.

when i saw this info, i feel like yours.
but if it is ture, we still have some function like zoom, etc.
functions like zoom only care about abs(x1 - x2) + abs(y1 - y2)
and:
if a app supports that user put a finger on, then put another, and the app recognize it as both finger touch the screen at same time, we can use it normally.
considered that promise of act simulataneously EVERY TIME is not so easy for human being, maybe developer will think about it.
so i think even if the hardware design of G1/saphire are really so different from a iphone-like screen, we should not miss something really important.
but i still want to know, if the message is true.

Touch Pro - Touch screen much less sensitive than iPhone???

Ever since I got my brand new HTC Touch Pro I noticed the screen to be way less sensitive than my girlfriend's iPhone.
For example in the Contacts app, when I use my finger to scroll down or up I find myself many times opening a contact rather than the screen scrolled down or up. Same goes for many other presses on the screen with the finger. I find myself using much more force than I naturally would use with an iPhone
I wonder if my unit is faulty requirming more pressure to the screen or maybe that just the way it should be by deisgn? I assume only users who used both iPhone and Touch Pro could answer that. I don't know anybody with Diamond or Touch pro so I have no way of checking it other than asking you guys.
Thanks
Iphone and Touch Pro use different types of touch screen.
We have Capasitive screen on iPhone which doesn't require pressure, just a touch.
And we have touch-resistive screens on most of Windows Mobile (inc. Touch Pro) which are less sensitive than iPhone...
Here is a link that might help: http://www.rycom.com.au/capvsres.htm
by the nature of the technology involved to sense your touch, the pro is less sensitive than the iphone.
the iphone uses a capacitive touchscreen which senses the electrical signal around your finger whereas the tp uses a resistive touchscreen which senses where your finger presses the screen in.
resistive screens are designed for sytli, and the "gestures" and flick scrolling implemented on many htc devices are a kind of fudged system to imitate gestures on the iphone. i know on my wizard i could adjust the touch scrolling sensitivity through schaps advanced configuration tool, but i'm not sure if you can do that with the touch pro. its all about how much force/speed you use on the TP.
i know you can get used to it, and it will function properly, but it is definitely different from the iphone. good luck!
Thanks guys. Both of your replies are most helpful. I began to fear that my unit had a fault in it. Seems to make sense that is how it works after I understand it. I most appreciate the responses. Thanks.

You will get better results using software designed from the ground up to be finger-friendly e.g. touchflo3d works well with only light pressure, and for contacts pocketcm also scrolls with only light pressure.
http://www.pocketcm.com/
Surur
On the plus side, the Touch pro(and all other non-capacitance screens) are less picky. I noticed that if you use fingernails on an iPhone it will ignore you. you have to touch with your finger. Our screen will respond to anything that touches it...pen, fingernail, rock. There are +/- s to both. Just have to get used to the change.
yeah pocketcm is great for scrolling also there is pointui if you dont like touchflo that is a free app that redoes the interface all scrolling too
and i usually use my fingernail for most stuff instead of my finger

I used a metal key depth gauge, and though it felt smooth, it put a nice scratch on the screen. It was a new replacement, and I hadn't got the screen protector yet. Good thing I'm not an anal OCD-head
Stylus' (Styli?) seem to be out of fashion at the moment, but they are far more accurate for doing work in spreadsheets and other applications with lots of data on the screen.

agreed, i have no problem being a "geek" and whipping out the stylus, especially when it magnetically snaps back in
is there a way of using stylus in capacitive screens?
Our fingers eletricity shouldnt be conducted through the stylus metal and reach the screen? Why it doesnt work?
is it true that HTC G1 is capacitive?
G1 is capacitive
Its not so much conducting electricity, more of eminating an electric field. i know there are certain "silver fingered" gloves that let you use the ipod/iphone with gloves on, and i would guess that there are capacitive styli as well, but i havent gone searching one out.

I have been whipping it out in public since the Palm 3.
I sometimes feel that Windows Mobile doesn't make the best use of Stylus input compared to Palm OS (tap a time to create a new appointment for example) but both zip along compared to finger presses on the iPhone for most serious work.

it's due to the resistive touchscreen. it's less sensitive than the capacitive screen in the iphone.
but the touch pro screen is actually less sensitive than other htc resistive touchscreens such as the kaiser. it's much less sensitive e.g. near the edges of the screen because of the bezel underneath, you need to press harder at the edges to get it to register a touch.

Resistive vs Capacitive screens WT???

this is not a rant thread but what is what is what is the hype about capacitive screens?
for one i enjoy using my nails to click stuffs on the phone and wont this be more precise?
i do not have the fortune to have a capacitive phone before but i really want to know what is so good about this?
So many pple cant be wrong right?????????
(p/s I WANT A HTC TOUCH HD 2 NOW )
First post in a long time!!!!
Well, maybe some of you have noted that i was not posting haha. its because im busy at school.. all those knowledge things etc.
Ok, when i saw that title i was already thinking in something that could make a revolutionary change O:!!
Actually, you can fit a resistive screen layer on a capacitive screen surface.
Just with the needed configuration, driver and alternation between screens (ie: using resistive for pen works as writing programs and capacitive for multi-touching things)
Imagine, using the fingertip to scroll smoothly and writing with a pen at the same time ;D! (Just an idea... no one would do that, but anyone could do ;D)
Just with the right libaries, drivers, software and OS modifications.
cuff cuff M$ could try this on its phone or for the new wm7 cuff cuff...
Just an idea ;D!
See ya !!
The sensitivity!!! Can someone confirm if the HTC HD2 has the same sensitivity to the iphone? I know it will be much better than resistive...

leo... while your waiting on the LEO, just go to an at&t store and play with one on an iphonie
capacitive means that you can put a screen protector on it and it will be pretty much just as sensitive =]
but perhaps the best part is that you can just glide your finger over the surface and it will respond...resistive screens are much less sensitive.
I have read somewhere that HTC was working on a capacitive stylus though..sothat would be the best of both worlds =]
am i right to assume,
resistive = precise but not sensitive
capacitive = not precise but sensitive

Resistive screens work by detecting pressure, so you have to press on them, sometimes quite hard. Capacitive screens can detect the lightest of touches. So capacitive screens tend to be more responsive. If you're trying to type on an on-screen keyboard at speed then a capacitive screen is usually far better - you can actually type rapidly rather than having to methodically press. each. key. one. at. a. time.
Another important difference is that, for practical purposes, resistive screens cannot support multi-touch - they can only detect being pressed in one place at once. That means they can't do things like iPhone-style pinch-zooming which requires the phone to track you pressing in two different places at the same time. (There are multi-touch resistive displays but they're too expensive or difficult to use on a device like a phone).
The upside of resistive screens is that you can press them with almost anything. A conventional stylus won't work on a capacitive screen, neither will your fingernail - only skin. So you can't stab the screen with a convenient pen-top, and it won't work if you're wearing gloves. There has been some work done on creating special capacitive styluses - I'm not sure how well they work in practice and they're not yet widely available.

A capacitive one works like the touchpad of a laptop. Sometimes i would prefer a capacitive screen on my Touch HD but sometimes even not. Because you can get much easylier error inputs with a capacitive screen. It just needs that your finger touchs slidly the screen and a input is made. But with a resistive screen you really have to press on it.
A screen with both tecs would be nice, have read something about this, but donĀ“t remember who is inventing this.
Don't know if it's because it's capacitive, but the iPhone screen always seems more readable in direct sunlight compared to my Touch Pro (or Touch 3G, or Touch).
For me personally, I think the problems of cold hands or a stylus not being able to work the screen outweigh the benefits. I also can't get my head around pinch to zoom - I love watching iPhone users trying to demonstrate the feature with one hand, sort of juggling it around trying not to drop it. I prefer double tapping on the bit you want to zoom in on. I can't wait to play with a Leo and see which works best in a 'Windows Phone' environment.

Well obviously pinch-zoom is not designed to work one-handed, but then neither is using a stylus. One advantage of pinch-zoom is that it lets you pick which part of the screen you want to zoom in on and exactly how much you want to zoom in by. Using a zoom-bar doesn't give you any control over where it zooms - it'll always pick (say) the top left hand corner of the screen as a reference point; double-tapping lets you pick where to zoom, but not by how much. Other solutions require additional gestures or presses. Pinch-zooming is also extremely intuitive - non-technical people get the hang of it instantly. Other types of multi-touch gesture are often very intuitive too; for example, running Google Earth on the iPhone, if you want to rotate the map you simply take hold of it and twist.
I think it's interesting how many people were claiming that resistive is better than capacitive whenever they were trying to bash the iphone, yet now those same people can't wait to get their hands on the Leo's capacitive screen.
Personally, I'd rather have resistive. The difference in sensitivity isn't great (so many HD reviews said how close it was to the sensitivity of the iphone). Multitouch is overrated. You can easily zoom in and out with a circle motion on a resistive screen. For me, neither of those capacitive advantages comes close to the benefit of being able to select with a stylus far more accurately than you ever can with a finger. No need to pinch-zoom in to select that link on a web page, or to select a cell in a spreadsheet. That's what's important to me.
capacitive is not good for drawing precise pics right?
HP tablet laptops have some hybrid of resistive and capacitive screens. They have a switch on the side that flicks between them and so they support multi-touch AND stylus
HP Laptop
My mates got one and its dead impressive. Just a shame the screens only 12" If they had them on 17" laptops like the one im using i'd be well up for it!
Capacitive and pinch zoom are both well overrated!
I can touch the screen of my X1 and it responds - no pressure. And I can zoom in by double tapping. Can't see what all the fuss is about to be honest. Probably something started by iPhone fanboys!

I totally agree. I don't want to lose the accuracy of a stylus. Why should I have to zoom in to click a small link with a fat finger, when I can click it unzoomed with a stylus? Same with a cell on a spreadsheet.
Multitouch is just a gimmick that really doesn't add anything useful. Either double tap or use the circle gesture to zoom/unzoom.
RIM applied for a patent for a dual capacitive/resistive screen about a month or two.. so someone is working on it.

thats my laptop, did not know it had a hybrid screen. there no switch on the side, the pen works and the multi touch works (i think, if i press in 2 places it the marker goes to the middle) without press any switch.
People who say there x1, diamond 2s and so one are as sensitive as an iPhone, have not tried seeing how gently you can touch it.
I do like capacitives screens, but I will feel lost without a stylus.
Has anyone else noticed on the iPhone, it doesnt respond to a touch with a nail, but if you touch with you finger and then without taking your finger off put it so only your nail is on the screen it still responds!?
Hopefully HTC will soon release the capacitive stylus that isnt a joke like the pogostick one.
Shasarak does make a very good point though regarding the extra operation being involved after double tapping in a particular area - I guess I'm taking the 'scroll wheel' on my Touch Pro for granted and using it to do the second operation without even thinking about it ; )
As an aside, boy would I like to see physical scroll wheels with navipads underneath make a return, not to mention dedicated camera buttons!

this is why capacitive screen sucks!!

just got my Acer Liquid with android.
i cant use my finger nail to touch the screen or use the onscreen keyboard with nail!
it' so much easier with resistance screen to use nail and 1 hand use!
you could glue a small magnet under your fingernail
i dont understand all this hype about capacitive screen. it really hard to type onscreen with finger and not nail!
and i dont understand all the hype about htc hd2 with capacitive screen, i dont want no freaking capcative screen!
i thinking of selling my acer liquid, i really dont like capcative screen!
Get used to it. It looks like all the begging and hype for capacitive means its not going away any time soon. Instead resistive seems to be on its last days.
I have heard though that someone was working on a dual cap/res screen. Now that would be useful.

Assume this is the Euro version?
With capacitive screens you have to almost touch above where you want. Not just and edge of where you want. It's hard but you get used to it. I much prefer resistive though and that's why I won't buy the HD2 or the Hero. Eventhough I want Hero so bad.
I've havd plenty exprience with both types of screens and can do everything better on resistive. I can type so much faster and accurate and can hit the smallest of links.
Capcitive screens require large screens and buttons to work right. Why do you think all the icons and buttons on the iphone are big? Not cause your grandma wouldn't be able to see them if they were small but because it's more accurate if they are big. That way you don't have to be exact. You can be sloppy with the touches and still get what you want.

True but having that little pressure gives you more control of where you want to touch. And I like setting my thumb on the screen wthout actually pressing something unless I want.
Being able to press on the keyboard gives you a better feel and more control of hitting the right letter and faster because it feels more natueral.
But to each his own. Each has their pros and cons it's up to the individual to choose which combo of pros vs cons they prefer.
I would take accuracy and pressure presses over light presses and multi touch any day.
Resistive is getting more sensitive as the years go by. So I wouldn't call the tech dead. Resistive can also do multi touch. But Drivers and such have to be created and also the OS has to support it.
This is where I get confused. My fuze (Raphael) has a resistive screen but a capacitative d-pad. I have gscroll, which allows gestures and tapping on the d-pad. It may be a little less sensitive than using a finger, but it also responds fine to a nail. Maybe screen construction is different, though.
Yeah, and i got rid of my palm pre for the same reason, couldn't use it on my motorbike with the gloves on, went back to resistive with the acer f1, now biking and texting at the same time (NOT !)....
So far, I am underwhelmed by capacitive screen on Hero

I'm not used to it yet, but I've only been using my Hero for about a week... Right now it's stock from HTC, not rooted, so I have not even consulted the Hero thread here yet to see what tricks and rigs they've got going.
While I will agree it is smoother to touch and glide/slide your finger across screen to scroll or flip to next page, truthfully, even on my T-Mobile Wing, old tech but made golden by the ROM chefs and app developers, I have had no problem for years flipping up down in iContact contact list, and more recently on Nitrogen song lists, or through a long file directory via Total Commander. In fact, I have, so far, felt that on the resistive screen, a flick up or down can be done with different force or speed, and results in different speed of scrolling through the list and where the screen lands at stop... whereas on my capcitive screen Hero, when I am flicking up down a long list of Gmails, I seem to only get one speed, and it's very incremental, I can't flick it to get down to the bottom of the list as I have been able to do on my little old T-Mobile QVGA Wing.
Same with browsing a webpage, especially a long article, and wanting to flick to the bottom... Can't do it (yet, again, not sure what the rooted Heroes with XDA ROMS do there) on my capacitive Hero.
Likewise, take the newest UI app made for WM (resistive) devices: Androkkid from Simo -- It has a UI like the Hero/Android, and it is so easy to swipe the screen left to right to flick to next and previous pages. It glides, no resistance... on the resistive screen !
Now THAT move on the Hero's capacitive screen is for sure much smoother and requires the lightest of touches. So, win 1 for capacitive.
And with s2v (slide to view) and various photo apps including rescoe viewer, a quick rotational arc gesture of my finger on the screen flipped a photo from landscape to portrait -- not simply for viewing (which accelerometers arguably do simpler, but I have not found it the case yet; there's lag time) -- but also for cropping and editing a picture.
One of the big arguments FOR capacitive screens is multi-touch and the squeezing and pinching to control zoom levels. That myth got shattered with browsers like Opera mini 4.2 and skyfire, and Netfront and Iris, etc. Tap-tap to zoom is SO much easier, and less RSI (repetitive stress) on finger muscles just to perform these multiple pinch and squeeze actions. I have seen ZERO value so far in this supposed selling point of capacitive screens. And, conversely, the resistive screens handle zooms and size changes fairly effortlessly, and very intuitively. So, to me, that's a win for resistive.
I don't get it (yet)... I have found no gestures on the Hero, like swiping right to left to go BACK on a website, or in any app. As much as I absolutely love this new Hero, I didn't want this to be the case, but the ergonomics of holding the device, hitting the hardkey back button (which requires a serious push, not a soft touch), as well as having to push a manual key for MENU options? All really taxing on one's hands and finger muscles even after a short while like 15 minutes straight.
Please someone tell me that XDA has given the Hero, and its capcitive screen all sorts of really simple and smooth to touch gestures that I can program to replace any hardkey function, especially: Back key, Menu key, and even volume controls.... All much easier to control on the resistive screen. Slider control actions like a touchscreen volume control left to right? As many have said, the target area for the finger to hit the control is very unforgiving... I've had to try again several times in a row... vs on resistive screen, such controls are so easy to control , whether with my full finger tip, or with a fingernail, and the precise control of stopping and sliding is more precise on resistive, in my view. Again, win for resistive.
I much prefer resistive though and that's why I won't buy the HD2 or the Hero. Eventhough I want Hero so bad.

Are you paying attention? I can't quite say I am disapponted with the hero, because it is a stunning phone, with a great UI, and beautiful screen, and yes, shiny and elegant, with a great build quality. But if I can't discover gestures or ways to use touchscreen controls to bypass these hard-buttons, i can for sure say, no, it will grow tiring, I hate to say. Though again, i do not know what the new firmware will do, both Android's 2.1 and HTC's sense upgrade. (I know this has nothing to do with cap vs res screen, but I am really surprised by how stiff the hard buttons are on the hero. They feel like first generation calculators, vs the light touch keyboards from apple, for example.
I've havd plenty exprience with both types of screens and can do everything better on resistive. I can type so much faster and accurate and can hit the smallest of links.

Resistive wins HUGE here. I almost never used the hard keyboard on my wing. I have always preferred an on screen keyboard, for rapid entry, and composing longer messages. And the app I used this past year on my Wing is Finger Keyboard -- oh my god it is so more advanced than even the HTC soft keyboard on the Hero that is the makeover for the default android soft keyboard. From the UI and color differentiation of FingerKeyboard, to its multi-functions and programmable shortcut phrases, to the real petal to the metal consideration of my fingers hitting all the right keys -- FAR greater accuracy on the resistive keyboard with my finger, and, like you i do like using a stylus for tapping out longer messages, or for entering long passwords that are combos of numbers and letters, cap and lower case. The rapid tap sequencing on that resistive screen using a stylus to accomplish that is easily 3 times faster to enter a complex username and password for sites that require it. A big win for resistive. Not even close.
Capcitive screens require large screens and buttons to work right. Why do you think all the icons and buttons on the iphone are big? Not cause your grandma wouldn't be able to see them if they were small but because it's more accurate if they are big. That way you don't have to be exact. You can be sloppy with the touches and still get what you want.

But I will quibble: I don't think the decision tree of how to design the iphone began with -- oh, looks like we're going to need big icons because we're using capacitive screens. I think more likely it was Jobs swooningly saying "how do we fundamentally change the user experience of using a touch screen phone... And I'll bet that whole pinch zoom thing was more of the driver of "we MUST have multi-touch; therefore capacitive"... and the bigger icons were absolutely a usability design issue that solved for rapid selection of a large variety of items, even if the phone is mounted in your car near the steering wheel. I have to say, that was breakthrough thinking on their part, and the icon size issue should not be minimized as a "must make do with" reaction to the target accuracy of capacitive screens.
But yeah, I am with the original poster. But since I am new to capacitive all together, I am guessing there has been thread after thread of this same discussion 200 times over since the first iphone came out, and people were comparing it to WM devices.
So I hope someone can nevertheless explain to me: WHAT is the alleged advantage of capacitive other than pinch-zoom? I don;t get it at all.
Sadly
I think it is because WM is heading a a very very user friendly interface. Like the phone. There are trying to dumb the whole o.s. down and have the same things as the iphone has, to remain in the smart phone wars. Think this is all because of stupid apple
I agree, it's all a big trend to follow the iphone, a pity it's going to ruin whats great about WM in the process
I love my hero because of the capa screen, it looks so much better than the resistive ones, colour/clarity ect. i dont have to keep askin my mates " have you seen my stylus" lol and i dropped my ash tray on my hero the other day and not one scratch on the screen lol id hate to see the damage to my touch pro's screen if i did that lol

Just because it is a capacitative screen doesn't mean that it is made of glass...
And I just can't wait till the multi-touch for resistive screens gets ported over to the TP2. It's already been proven to be possible on a larger screen, but hopefully it'll work on smaller screens. Still like resistive more than capacitative.

Stylus enabled device list?

Capacitive screen may feature multitouch, but this seems to come with the price of losing the stylus.
As user coming from the age of Windows CE, (Cassiopeia 105), I really appreciate its use and I believe that there are many cases where it cannot be replaced by fingers (including typing where you can hit keys really fast with some practice). Fingers tend to obstruct what you want to see (try to play Bubble Breaker with your finger and you will know what I mean).
I currently have a Touch HD and I will be replacing it at some time soon. Do you know any devices at the level of Nexus One / Touch HD2 that will include a stylus or at least be stylus friendly?
Thank you very much!
Nothing that has a capacitive screen will include a stylus, but there are capacitive styli, and you can make one yourself:

Never tried that, because I don't have a device with a capacitive screen. I can say that winmo(uses winCE kernel) is still stylus friendly, and you can turn off touch flo, and change the keyboard if you want. Can't say about android, though. I actually still use my stylus a lot, as its much faster than my finger
By the way, do you think that you could live without the stylus? Fact is that capacitive screens do not allow fingernails and thus accuracy is further decreased. Big fimger friendly icons are fun but sometimes they are a waste of space.

Even if I make my own stylus (or buy one) will there be a possibility to attach it on the phone (even externally - as in Omnia I think)?
I am really concerned as regards this trend to capacitive screens which offer a rather useless multitouch and the tradeoff is the accurate stylus. I hope that in the future high-spec resistive screen devices will continue to emerge.

MultiTouch Tester App

I tried the MultiTouch Tester app on my Galaxy Tablet, and look what it shows. [See attached image].
I remember using this app on my ViewSonic GTablet, I believe it only read maximum 2 fingers.
Each circle is a touch, those are 5 fingers touching the screen at the same time, and the screen rendering/recognizing the 5 touches. I BELIEVE the Viewsonic only recognizes 2 touches.
- Now this could be the reason for Keyboard typing issues.
- Can anyone confirm how many touches the Viewsonic GTablet renders?
Tested on GTab.
Confirm only 2 points.
i new something was weird about this.
Isnt this a capactive screen? is there another module that recognizes touch? digitizer?
Keyboard typing issues are much much better now that we know how to calibrate the touchscreen - there's a thread on it in the forum here called touch screen sensitivity. The calibration out of the box is bad on a lot of people's units. Not saying I'd want to write an essay on here though.
But the touchscreen does still max out with 2 touch points at a time. We don't know if that's a hardware limitation or not, but its not much of an issue for me honestly, because sensitivity is awesome on my properly calibrated screen.

I remember that I have read a review, it stated the screen is two points multi touch. I think that it is the same for advent Vega and a7.
From my tests:
Two point touch screens: Droid Inc, Motorola Droid, G-tablet,
5 point: Evo 4g

Just tested Sammy Captivate: 5 points
Evos were mfg'd with at least 2 different panels/hardware. ROMs and Kernels can change 5 to 3 point, but not a 3 point sensor to 5. (I unfortunately have the 3 point )
Do you know what hardware the touch panel is in this tablet?
The Evo its atmel224 - 5 point and atmelc03 - 3 point from what i remember.
try "adb shell cat /sys/android_touch/vendor" and post results. (i dont have a tablet yet )
