Hello. I just bought the Nvidia Shield K1 tablet. It is fine for the most part. However, I don't know if it is lag or touch sensitivity or what, but it seems to me that whenever I am scrolling, it is jumpy and erratic. When I let go of the screen, it suddenly scrolls faster. Sometimes even a full page down, even if I barely scrolled. Should I try to get a replacement? Thank you.
First make sure that your Shield power control settings are set to max performance. Or at least to optimized. Also try rebooting it. I have occasionally had that issue with my St but almost always its when I have my Shield power control set to my own setting which is at 50% CPU level or whenever it just needs a good reboot.
I know that mine behaves like this (worse actually) when I'm charging it with a 2.1a or faster charger. I chalked it up to the screen being less conductive while receiving a lot of power. Does it occur all the time?

I solved the issue by recalibrating the screen. hitting model number: shield k1 or one of the items in the about system like 10 times gets you to the calibration screen.
then hit calibrate. don't touch screen. then when it asks to reboot. reboot

What's the difference between Max performance and Optimized?

I just got the 32G version transformer. There is a very annoying problem with the touch screen: sometimes it is not registering my touch at all, sometimes it seems that you have to push hard.
I am not sure if this is the touch screen problem or the system is busy with something else?
Anybody else having the problem? Any ideas to solve it?
The firmware is the latest version.
I too have noticed this issue from time to time. Not sure what it is though.

The touchscreen does seem a bit insensitive on my 16GB TF. Not necessarily unusable, but sometimes I have to touch a button a couple times to get it to respond. Most often the menu button that appears in the top right corner of some apps.
I am pretty sure this is a software related problem. Sometimes, the touch screen feels quite responsive.
What is the official way to report problems to ASUS?

Indeed. The touch digitizer and even it's driver works flawlessly - start Fruit Ninja HD and you can enjoy most responsive multi-fingers (4 or maybe more) touch ever.
But everything except games is considerably less responsive to touch.
The touchscreen on mine just completely died. Completely not responsive. I wish I could blame it on a faulty app or something simple but I put it to sleep and when I woke it 20 minutes later, I can't do anything with it. It responds to all the physical buttons just fine and the screen rotates and everything but it just doesn't respond to any touch.

I just installed Fruit Ninja HD. Although I am a newbie in cutting fruits, I am pretty sure the touch screen just doesn't register sometimes, even in Fruit Ninja.
My firmware build number is: HRI66.US_epad-8.2.3.9-20110423
Coming from Xoom, although the TF's IPS is much better than Xoom, but the touch experience of the TF is much much worse.
Sometimes you have to press hard and longer to register, I am wondering if there is a way to change the touch screen's sensitivity?
Whatever reason it is, it should be very easy for ASUS to reproduce the problem and fix it!
Try the app Multitouch Test in the market. It seems to be a lot more sensitive than some of the other apps are (or even the OS) regarding touch sensitivity. (Or at least it seems to be)

Thanks. Downloaded and tried.
When it's normal, it can track 10-finger touch easily. However, the main problem seems to be the response time for repetitive touches. The system seems to be not able to keep up with normal typing speed touches. It will register several touches, then non-responsive for a while. If you wait a while, like several seconds, it will respond again.
Is there a good APP to check CPU settings and utilization ratio?

What do you mean by cold reboot? I have reset it a few times by holding down the power button.
Interestingly, this thing is mentioned in Engadget UK's review (http://hartantolestari.info/search/asus-eee-pad-transformer-screen-is-not-working)
A lack of responsiveness is also evident throughout the Android UI. Aside from a delay in activating the function you’ve selected, there are also troubling instances where input isn’t registered at all. That leaves the user with no less than three potential scenarios when she doesn’t see an immediate response — she could be looking at lag, an unregistered tap because of software, or an unregistered tap because the physical input was too light. Such uncertainty doesn’t build a great user experience and the Transformer, unfortunately, doesn’t offer a great user experience. Much of that is, regrettably, down to Honeycomb itself. It’s not a finished product yet. It’s actually a fair distance away from a finished product. Some apps are done to absolute perfection while a lot of the “glue” bits, the stuff that goes between the apps and basically makes up the OS, is either confused, not responsive enough, or broken in some other way. Let’s take these things in turn, starting with the good parts.

I would reccomend against pressing hard. That is a good way to damage the lcd panel and the digitizer hardware. Capacitive screens dont register pressure just electircal conductivity from skin touching the screen. I would say any lag you are seeing is most likely software based as others have said.

Hmm, I have tried rebooting the device many, many times and still no change. I wiped user data hoping it would help (nope). I just don't understand why the touchscreen would stop being responsive to any input. It wasn't jostled around or treated badly in any way. I just had it in my backpack, which I was carrying by hand and the Transformer was in a padded compartment.
Overall, I am rather disappointed and disillusioned with Asus. The Transformer's terrific when it works but I've had to deal with the deep sleep issue at least once a day and then to have the touchscreen go dead entirely is terrible. The first I can see being a software issue that can be fixed but the second is probably shoddy hardware.

Cold reboot is holding power button until TF shuts down, ignoring shutdown dialog.

almost seems as if they didnt test the xoom. it feels faster than the tf bc its screen is more responsive.
i wonder if the screen could be calibrated manually with the config.ini lie the nook color.
Here is some update: after the TF slept for a night, I pushed the power button. The touch screen is just not responding at all on the lock screen. I let alone the TF for half an hour or so, pushed the power button again, now the touch screen worked fine. Unlocked and into the home screen, no problem with touch for about 30 seconds, then it becomes intermittent again.
I will call ASUS support tomorrow. Hopefully there will be some firmware update very soon to address this, otherwise, I will have to return it.
The weird thing is that if this is a software/firmware issue, lots of people should have reported it.
OK, I have created a case at vip.asus.com/eservice/techserv.aspx
Looking at some Youtube clips reviewing TF, their touch screen seems to be fine. So this might be a bad unit. I will return it next week (bought from local Fry's) and hopefully they have replacement units!
I have created a vote regarding the TF's touch experience.

Good luck! I got mine from Amazon and they are completely out of stock. The only option is to get a refund since they don't have an expected in-stock date so the CSR can't put a replacement order in for me. Every online retailer I've looked at is also OOS. Hopefully more come in soon.
I also spoke to Asus and they are willing to repair mine but not to give me a loaner or just outright replace it. That is really too bad. I was hoping they would be more like HTC, which has great customer service in my experience and gives out replacements at the drop of a hat. If the Flyer wasn't such a POS, they would have had my business.
Hey guys,
messing arond with my new transformer at the moment. Keyboard delay and power drain on the dock suck, but the overall performance and usability are more than enough to let it stay.
Next week i am going to a small local festial, the wacken open air, and i am currently thinking about using my transformer as an external battery for my iphone. It should at least be able to charge my phone for two more times, so i can use 3g and the cam the whole festival long instead of killing those features for sqeazing out the battery up to 4 days.
I tried charging it at home, but at the moment the display turns off, the Iphone stops charging.
I could start playing music on the tab to keep it from going into standby, but that feels like cheating
Is there any way to just activate one (or all) usb-ports without turning on the display or even better: without turning on the whole OS?
Thanks in advance and sorry for my bad english.
most festivals have cellphone charching stations
If you really must charge your phone with the dock, I'd turn off the auto brightness on the screen and turn it all the way down, then set the screen sleep to "never".

I have a suggestion: dump that I-****e and get an android phone with a user replaceable battery....just saying...
I dont know of any method of doing this, but I would be interested in one.

What does your TF do when closing the dock? Will it stay off and asleep?
I just got my B40 dock back after RMA (timeline and replaced parts number summarized here). I didn't really pay attention to how it was before I sent it because I only had it for a few days, except that it didn't sleep even when MobileDock Battery saving mode was set. Now after the RMA, it stays asleep correctly, but when I closed it in a darkened room, I noticed a light coming from the gap. It woke up!
In short, opening and closing the dock would behave like this:
1. While open, press the power button on the tablet (or the lock key on the dock). Table would go to deep SLEEP and would not wake up with a keyboard tap. However, as I close the dock and it approaches about 5 degree angle, the screen would turn ON and, worse, it stays on. Pressing the power button would not turn it off.
2. While ON and not asleep, close it. As it approaches 5 degree angle, the screen would turn OFF. It would turn ON as soon as the dock is opened again (regardless of how long I left it closed).
FWIW, the TF is B50 on Revolution ROM 2.1.0.
Edit: reluctant of another RMA, is there a microswitch inside the dock that detects the open/close position? If so, I might just disconnect it unless there is a software fix.
There is no switch. There's a magnet right beneath the - button that tells your TF to go to sleep when you close it and wake up when you open it. Don't put it to sleep before you close it. I have b60. When I press the power button before I close it, it would still stay asleep and wakes up when I open it. It's not a dock issue. It's a TF issue. May be the b50 is built differently. Don't know.
I uninstalled "No Lock" and now the screen stays off in scenario 1 above. But looking at CPU Spy, it wasn't deep-sleeping and instead it stayed at 216.
Not doubting you, but how did you know that your B60 was deep-sleeping for sure?

I don't. All I know is that my battery lasts forever. Besides, if it doesn't go to deep sleep, then fine. I don't care. Like I said, as long as the battery lasts me the whole day without me worrying about charging, I'm good.
Why are people so anal about this sleep thing? Get an ipad if you want your device to deep sleep that badly.
I think there is a difference in being anal and trying to be sure about what our device is donig -- especially after one has just received it from RMA.
Being in XDA already makes us more attentive about our devices than the regular population, so can't blame someone for checking.

Actually, no. I think it's the opposite. If you're here in xda then chances are you are fine with some of the imperfections that come with our devices. That's why we mod.
It's the ipad users who expect things to be perfect. Myself and many others have pointed this out many times. iOS devices crash just as often as everything else. The only reason people think they don't is because when they do crash there's no error message. One moment you're in an app and the next you're on your home screen. iOS is built that way. It's like sweeping the dirt under the rug to give the impression that the place is spotless.
why are we even talking about iPad? Geez...
It feels like the phone takes way too long to recognize and respond to touch commands.
I don't know why but it feels like touch responsiveness is getting delayed somehow, It's not about processor power or even overall hardware performance I can literally touch the apps launchpad move my finger off the screen and still have time to see the animation and the vibration take place which isn't true for the galay S3 running touch-crappy-wiz, Why is that? Isn't it supposed to be more responsive?
Have any of you guys noticed or experienced this issue with yours Moto g?
That doesn't sound sound normal. Is it the same when yuo boot up in safe mode? Hold the power button down until it offers to switch off, hold down for 3 seconds and tap on reboot to safe mode.
If its running smooth in safe mode, then that means that there is a bad apple in the list of apps you downloaded and it would be best to weed out the apps.
Cheers,
Nicole
I tried booting in safe mode And even though it feel quite a bit less delayed doesn't feel that much different either! I will wipe cache and unload some apps.. Thanks for helping!

/** this method was discovered empirically, which will help us to eliminate approximately 80% of the ghost touch , the touch ghosts appear in boe panels **/
step one:
reduce the scale of animation in .5
developer settings.
Step Two:
disable Motorola gestures minus the ambient screen and the fingerprint sensor lock.
Finally:
go to screen, color mode and select standard.
Congratulations!!!:victory:
this will drastically reduce the ghosts touch.
comment if it worked.
this solution is a speculation (it worked for me):good:
Not work for me, The only thing that works for me is to have the brightness to a minimum.

Yes, I have noticed that outside in the sun, when brightness is at max(if auto brightness is enabled), the screen likes to press on its own lol
In my case the ghost touch issue only appears when i plug my device into a <1000mAh charger, a common case is when i try to charge it with an old sony 850mAh charger, the ghost touchs appear here. Other daily case is when i plug the device in an USB port (500mAh), it automatically fail.
My device never failed when it's not plugged to an energy source.
I charge my device with a LG Nexus 5 (1.2 Ampere / 1200 mAh) charger and i never faced any ghost touchs with it. The stock TurboPower works well too, but i prefer to not use it.
So, in my case it's amperage related.
Mine ghost touches no matter what. Even when not plugged in. Not very happy for being a 4 month old device.
