Touch Sensitivity

Hey is anyone elses GTab's touch sensitivity kind of off?
I noticed, compared to the iPad and Galaxy Tab, some times it takes me 2-4x of tryinng to press something to get it going.
Its almost like the screen cant pick it up sometimes. And sometimes when scrolling, it selects things, when im just Trying to scroll..
Also the top left HOME button on screen is always iffy, most times ill need 2-4 more times 2 press it to get it going.
I am using TNT 2.2.
Anyone else noticed this? i feel like its hardware.

Definetely not as responsive as my EVO. Maybe its the cheap screen. I wish it could be fixed via software, but fat chance. I guess not all capacitive screens are created equal.

You nailed it. IMO Samsung has been making the best color screens for years.

Have had absolutely no problems with touchpad responsiveness from my gTab... Just as sensitive and responsive as my Dinc.
Really does seem like this hardware is hit or miss... Some tabs have no issues some have many.

You guys are just plain spoiled. I've gone through Palm IIIx to now the gTablet, and it just simply has the most responsive touch screen that I've ever used, but I've had recent experience with the dreadful Augen GT and the slightly less dreadful White Pandigital Novel, both of which had worse touch screens than other devices that I've used.
One thing that I do, do for the gTab though is to clean the screen quite a bit. At a minimum I do so before every use as I find the fingerprint/body oils buildup to be annoying in fairly short order and it might have some impact on touch responsiveness. It's the worst fingerprint magnet that I've ever seen actually...

No issues here with single touch sensitivity, pretty good on that. Just as good as my Nexus One. Multitouch and pinch-to-zoom still a bit flaky. I am hopeful that will be resolved by software and/or driver improvements, as it was on the Nexus One.
The only issues I have are when the screen is too dirty or too clean. When I really scrub and clean the glass off entirely, at first it's a bit too "sticky" almost when my finger contacts it - maybe that's because it's winter here in the Northeast and my skin is dry. Once I've used it a bit and it gets some finger grease on it, it works perfectly. But if it gets grit or solid dirt on it, that can definitely interfere with the touch screen too, as with any capacitive screen.
I suspect the optimal thing would be a really good screen protector that's easy to clean and has that smooth finger contact feeling out of the box, like the iPad's glass does, for example, which I think has something to do with the oleophobic coating.

Typing this on my gtablet. The issue for me is the keyboard. There are parts of the screen that are unresoonsive making some letters not get tapped. The A key and l keys in particular. As a result I can't type smoothly or naturally because I will make several errors along the way. This does not happen onky iphone or my wires ipad.
it might bemy rrleason for sending it back as it takes too ongoing totyr correctly and I get tire d of all the corrections.

Well if your using the stock tnt keyboard, it sucks. We can learn from the ipad, with the size of the screen it has huge keys that cover a lot more of the screen then our stock tnt keyboard. I use smart keyboard pro with the key heights set to maximum and it works so much better, like 100x better. Even has voice to text.

Can people check their keyboard? I find that if I type most of the keys they type fine. However, the letter a key seems to only work when pressed offcenter which prevents. From typing properly as I must deliberately slow down and make sure it is correctly typed otherwise I get many errors. Could this be a defect in my screen?
Or is this a ui problem with tnt?
This could be a deal breaker as I misspelled every word if. Has h letter A

Letter A
I have the same problem with the letter A, and sometimes P. Otherwise touch is great

Figured why this tablet is driving me nuts. There are two dead zones on this tablet. Someone please do this test so I can figure out if this is just my tablet or all g tablets.
Download mulitouch vis test. Do rapid light touches in the area where the 'a' key is and delete key are. If I do this test in the middle of the screen it registers every single tap. But in those two areas I can sometimes tap 10 times in a row and not have a single tap register.
If this all g tablets then I think it's going back.
Also is there a keyboard with arrow keys? Trying to place the cursor can be a real pain.

Agreed bout the dead spots. The stock tap n tap western keyboard seems tominimize them due to the angles but if I try another keyboard I miss the a and the return button all the time

Downloaded the app as well because I, too, am having the same screen non-responsiveness issue. Lo and behold the area where the "L" key is is a pretty dead spot. It would register about 40% of the quick taps I did in that area. Is this is a software issue? If so, I can live with it and hope our wonderful devs release a software build that resolves this otherwise, this thing may be going back because it's driving me up the wall!

I do see the occasional missed tap here and there, but no consistent dead areas that I've noticed (the A and L buttons on keyboard seem fine to me).
Multitouch sensitivity is wayyyyy mis-calibrated though - you have to use very heavy finger presses to get multitouch to register. This is some sort of driver or calibration issue that should be easily solved.
I found a binary called TSCalibration in the /system/bin directory on my VEGAn ROM G Tablet. Tried running it from terminal, but it seems to be looking for a calibration.ini file on the SDCard. I'd be willing to bet we could figure out how to fix some of the touchscreen issues with some work, because I suspect they are principally software related.

If your issues with the touchscreen are anything like this...exchange it...
My new one requires very little effort if any at all to get the screen to respond...
However, if you're talking about the once in a while miss of a touch...yes, I agree with cutterjohn....you're spoiled. Return the device asap, so I could pick it up from an outlet...please?

There is a big difference between these dead spots and the occasional miss. I have no problem with the occasional miss. I just have to adjust to how my finger touches the tablet to get more consistent hits.
There are areas of my tablet that consistently do not behave like the other areas. Does that sound normal to you? I can't have a tablet where anything in the 2 corners is extremely inconsistent. If I have the tablet oriented a certain way the soft-buttons get put into one of the bad corners and that is really frustrating.
I don't think it is how I am holding it because the problem follows the physical corners and it is not relative to my hand. So that rules that out. And I washed my hands and gave the tablet a good cleaning so dirt/grease/grime is not an issue either. It could have been too clean but why only two corners?
I have many weeks to go on my 30 days so I will keep screwing with it to see if I can come up with anything that is a workaround or explains why it is happening. It is insanely fast and it's modding future looks extremely bright with such talented people. If I get fed up enough, I'll exchange it and hopefully get one with a even touch response for the whole screen or simply return it and wait a couple more months for Honeycomb tablets.

Whoa. That video was pretty bad. While mine is not like that (thank God), I just tried hitting the app drawer key and it only registered after the 13th tap?!?! seriously wtf. While it isn't a "dead zone" per se, that's still pretty bad. There has to be a software fix to recify this issue with the right side of the screen. (my "L" and "delete" button are pretty bad as well).

THAT is a defective product...
I'll do another video to compare with my new one...WITH funky assed salty sweat all over the screen. Works flawlessly...

Is your model that is working well running stock firmware and keyboard?
mine is tent lite and the stock keyboard is ok. It if I try to use the alternative keyboards then I get consistent misses on key presses especially on the letter a.

I'm always tapping *constantly*, like 10-20 times on certain spots around the corners and edges of the screen, I'm about to return mine because of this.. Believe I'm still in the 2 weeks with office depot, will have to go snag the $350 one over at sears and hopefully it will come with a screen protector this time (this one I have didn't come with one, wonder if that has to do with the dead spots)..

[Q] The display lights up if the sliding mechanism is even slightly nudged?

Hi, guys, have you noticed that if the right side of the sliding mechanism is slightly nudged, the display lights up? Here is a video:
http://www.youtube.com/watch?v=XNQ1nK3cutY
When answering, please share what phone and keyboard layout do you have.

Same problem with me.. (link)
Personally, I don't like the capacitive buttons.. and I'm becoming increasingly annoyed with the search button!
Also, I don't know if anyone else has this problem..
If my keyboard is slightly moved/nudged, it wakes the phone up. See video..

Oh, that's a relief, I thought I was the only one
Well, that's not a big problem, even if the phone is waked up, it's still locked and goes to sleep again in 3-4 seconds.

This is weird!
Mine's display light up after I slide it past the bottom keyboard row, it can stay locked while I can clearly see the spacebar!
How can the same device act differently like that? mine is a 7 Pro (not an Arrive), and I can see from your video that yours is a 7 Pro too.

If I push the sliding mechanism evenly, with two fingers, mine also lights up after the first row of the keyboard, just like yours. But try to push only the right side...

The screen is triggered based on a magnet I believe. So the amount that the screen must be moved to trigger the screen to come on isn't a precise thing.

Doesn't happen on my Arrive.

Hey, folks, do your phones light up when you divide the two halves?
http://www.youtube.com/watch?v=Yc6zNYu-La8
Please write what phone do you have - HTC Arrive, HTC 7 Pro, QWERTY or QWERTZ kejboard.

Mine doesn't light up if I nudge the right or left side. It also does not light up If split it in half like the above video.
It only lights up when I slide it over the first row of keys.

This is correct.
I don't have the manual for that phone. (it's similar to the mechanism shown for the TyTn however www.mikechannon.net or see here to get the general idea http://forum.xda-developers.com/showpost.php?p=2677085&postcount=3 ) HTC tightened their document security and it's almost impossible to get Service Manuals current devices these days.
However, as tiny17 commented, in HTC phones, the sliding keyboard activates "wake-up" by means of a small magnet which is glued onto the inside of the casing. As this moves past the magnet operated switch it wakes up the phone. You will see similar behaviour if you bring a magnet near certain parts of the case and in fact this is a way to locate where the magnet switch is located.
Also, using phone cases that have magnet clasps on them can also operate the switch and wake up the phone when sliding it in and out of the case/pouch.
So technically this is not a fault, but it can be annoying.

[Q] new tf700 screen imperfection ?

I notice a small (3mm x 3mm ) spotty blemish (four tiny dots arranged like the new windows icon) on the screen, probably in the actual LCD (cannot touch it).
It is only visible when the screen displays white.
I suppose this is a manufacturing defection. Anything else about the screen seems fine. quite solid build, except for negligible 0.5mm give on the left edge.
Anything else I should particularly check for? Shall I exchange it at bb?
There is really no anything else as big and as light as tf700, right?
Thanks.

Hello.
Not sure if we talking about same issue but I also have this white dot, almost like a dead pixel but it isn't. Its possible to be seen only when white background and easier to spot when viewing from side, not straight ahead.
I believe this is what is called hot pixel.
Bad thing about this is that I first had 1, then 2. Then I returned it. Asus said no problems. Now I have 4 and I am seriously considering to returing this. Just that I need my tablet for work and I know for Asus it takes over 2 weeks to consider what they would do.
Probably when not so hectic at work I will go and try returning again.
I have on right hand side some loosening. If I press the screen where is the volume buttons I can feel it moves. It is the only place of the tablet where this kind of movement can be spotted.
Yet 3 of the hot pixels are on the left side of the tablet. The newest one is close to middle but a bit more to right side.

I'll definitely return mine to Best Buy, but a bit debating whether I shall stick with tf700t after all.
Any clue whether there is any systematic difference between retailers / batches of s/n's ?

Fix Your Broken/Stuck Accelorometer

I've had a stuck accelerometer problem with phones, but also with my DJI Phantom drone. This problem manifests itself as:
- can't switch or rotate from portrait mode to landscape correctly
- camera won't rotate to landscape
- terrible VR performance, drifting
- bad gaming performance
- sensor readings way off
You're not going to believe the solution that has worked for me in both cases: you gotta bash it!!
Yep, your silicon-based accelerometers have fingers that can deflect with G forces, but when they get a big impact, they can get stuck at the extreme bent side. You probably dropped your phone recently, right?? Well, you can probably fix it by dropping it again in exactly the right way. It's like Fred Flintstone's amnesia.
You'll need to determine which side to drop it onto, and then drop it onto that side HARD onto a hard surface. You don't need to let it go, you kind of slam it with your hand. Do it at your own risk, of course, because you might break some other component!
Here's which side to whack it. For god sakes, don't just whack it randomly.
First, you'll need an accelerometer app. Install it and run it in metric mode. Set your phone on the table. Have a look at your values for X, Y, and Z. Two should be at near 0 and Z should be around 10 m/ss. The 10 reading is the table holding your phone against the force of gravity at 10 m/ss!
One or more of your numbers will NOT be as I stated, and that's the stuck accelerometer. It will be pretty much stuck and hardly changing at all, and it will be weirdly high, much greater than 10. ex: My X was at 167. (If you do not have one of your axis stuck on a very high number, you have a different problem, don't continue.)
If your X value is stuck sky high, hit the phone with the X+ (right) side onto the table
If your X value is a high number, but negative, hit the phone with the X- (left) side onto the table
If your Y value is stuck sky high, hit the phone with the Y+ (top) side onto the table
If your Y value is a high number, but negative, hit the phone with the Y- (bottom) side onto the table
If your Z value is stuck sky high, hit the phone with the Z+ (screen face) side onto the table (good luck to you)
If your Z value is a high number, but negative, hit the phone with the Z- (back) side onto the table
If you hit it sharply enough, you'll notice that the sensor is no longer stuck on the super high reading, and you're all fixed
Look on the bright side, it's not a drone. Since propellers etc get in the way of a table slam, I had to hit my $1200 drone - HARD - with a rubber mallet when it had the same problem. But it worked!

I have a Redmi Note 8 pro and the accelerometer was not working. The Y and Z axis were stuck at high negitive values. I was very frustrated as the camera app took pictures up side down. After searching the internet for a gud hour , I found this solution. I tried it and it worked like a charm. I had to hit my phone on my hand for both -Y and -Z axis. After both directional hits, the accelerometer sprung into action and everything worked smoothly.
Thank you so much. This solved my problem like a charm. This really worked.

Moved from Android Drones, because as the original poster tells me, this applies generally to devices with Accelorometers.
Mike

I still can't believe that it worked like it did. The Z axis on my Redmi Note 7's accelerometer was stuck, and it insta working again after throwing my phone on the floor. This is probably the least thing I would do (willingly) and worked like a charm. Thank you very much.

This post saved me. Almost wiped my Redmi Note 8 Pro. Worked fine just throwing it on the floor LMAO. Nothing like an armor case to protect hahahaha

MY HERO. the pockets in my sweats aren't deep enough so my phone kept falling out and must have konked itself into a hung accelerometer. A few drops on the bottom fixed a stuck negative Y axis. happy day!

[Q] Note 10/10+ Dynamic Screen

Cant seem to find anything concrete info about the display. Not sure if any of you got the s/note series prior to the note 10, but the screen on the note 10 is different. I noticed the screen color (especially on white backgrounds) shifts quite strong. What i mean by that is noticeable to the point i can see when it shifts color, unlike how iphone does it gradually on their screens. I thought the dynamic screen just means less bluelight?
so my questions are
is it just me who notice this?
is this part of the tech? if not then i have a faulty panel?
I have the note 10.

I usually notice stuff, but with Note10 I didn't or it didn't bother me at all. Color shift meaning when you tilt the phone or under different lighting?

99% of people says I'm just whining over nothing but I'm extremely sensitive to this color shift when I tilt the device a little bit. I love samsung amoled screens but I hate this color shift phenomena and it's usually a lottery. My first S10+ was awful but I had to do a warranty claim for other reasons and second S10+ has an almost perfect screen (only very minimal shift to blue).
I ordered 3 note 10+ to avoid this (and planning on selling 2 for profit) but all three had way worse screen than my S10+ in terms of color shifting, they turn extremely red/pink if I tilt them a little bit during normal use, they also have washed out, non uniform. gray (OneUI night mode) while on the S10+ it looks almost completely black and uniform, oh well.

I mean does the dynamic amoled screen shift colors or white balance like how it does on iPhones with their true tone display.
Cause I often find my self seeing the white balance shifting to red or green when I move to different lighting areas.
I assume its the brightness changing that may have resulted changing the white balance. Maybe my eyes are playing tricks on me. I sometimes see text closer to red than what or yellow (with blue light filter on)

Yea I was wondering is it a defect. Read above I don't think it's a feature. Again could be my eyes playing tricks on me. Funny how I didn't notice this on previous galaxy phones. Including the s10.

If it's only happening on the dynamic mode(I'm thinking your saying auto mode), why use it all. Dynamic/ auto means just that, it will and is going to shift depending on ambient light. Manually set it, and forget it.
But if you have set it manually(or even the auto) I would say it's more a situation that 'your eyes' made need something special(I don't know how iPhone shifts differ, as I haven't worked on one in a few years), and, it's not a fault of the device, as most people don't have this level of sensitivity or seeing.
