I have persistent issues with the touch screen.. it is unresponsive and inaccurate (I touch one part on the screen.. it "ghost" touch another region instead)... I am getting really annoyed by that... It's due to dirt around the sensors I think (cuz when i clean it, it's better) but I can't prevent dirt from getting on the sensors! Are all ebook touch screens like that?

You are correct, this problem is happening due to buildup of substances (dirt, sand, dust, etc.) around your Nook's screen sensors. If you cannot prevent these substances from getting on your screen, try putting your Nook in a case with a pocket cover. You can carry a microfiber cloth in the pocket to clean the screen when needed.
And yes, all eBook reader touch screens which are eInk act like this.

Actually most newer e-readers have a capacitive layer for the touch screen instead of the infrared sensors along the edge. I would recommend that anyone experiencing these issues search for and download Renate's app for testing your NST screen, It'll show you exactly what sensor is having problems and allow you to try and correct them.

Thank you for the FYI!
Would you care to link/attach the app you mentioned? I'd like to try it.
EDIT - Nevermind, after a fair bit of searching I found it. Here's the post with the latest .apk, and here's the post with instructions.
Download Touch.apk in the signature.
Also UsbMode.apk now shows touch coordinates too for a quick check.
It will also work with non-Nook-specific stuff on any Android devices (up to Lollipop).
The screenshot below was with a Nexus 9 using 10 fingers.
The number of points your device can follow may be anywhere from 1 to 10.

Here's a screenshot of what my NTG displays when using 2 fingers - strange that it still displays coord's instead of "2 points" like the Nexus 9 shot you attached does (except with 10, of course).
EDIT - By the way, @Renate NST, don't you think it's probably time to put com.temblast.reader.apk into your signature?
I didn't think there was enough room to show 10 sets of coordinates.
That's why you only see the first two sets.
After that, it only shows the number of touches.
Um, about the Reader, I have to see what the latest version is.
The development has gone off in a direction that probably is not useful for most users.

You haven't updated your thread on the Reader in a few months. Would you mind PMing me about the newer features that "probably are not useful for most users"? Or, better yet, update your thread about it?

So I bought one of the cases recommended over in the accessories forum, which holds the tab propped up at an angle. It really helps with typing and all around use when you set the Tab on a desk or table. The way the case works, the camera is on the side closest to the user. Whenever I open any game (Angry Birds, Vendetta Online, etc) it flips the orientation so that the camera side is on top, instead of on the bottom. This has made it unusable! The case designer had the right idea, since putting the tab in the other way would expose the charging port (It's a folio style case). I've tried turning off the automatic screen orientation setting, but it didn't help. Any ideas?

Here is a link to the case I bought.
Pics here & here of how the case folds.
Regardless of all that, the real question is... How do I run games and such with the bottom of the screen being the camera side? I thought the whole point of doing away with all the physical buttons was so that it could be rotated any which way?!?

Total guess here, but maybe it has something to do with applications that need to track orientation (like Vendetta) and/or programming decisions by the developers (Angry Birds?).
If its a programming thing, maybe theres a way to send a bug report to the developers about the orientation issue and they could roll it into a future update.
Or ... just learn to play Vendetta with the thumb controls and Angry Birds must be a whole new experience upside down ;-)
I saw a youtube-clip where a guy demonstrated that u could use a pen (or other objects) to control the screen. Was going to try this in a meeting today, but the function seems to be deactivated. I have browsed through the settings and can't find the option to active this.
I have tried the setting enabling the use of phone with a glow, but it wont recognize any of my pens.
Anyone know?

Any chance of a link of the YouTube clip to see? I'm pretty sure those pens would've been a capacitive type for it to work on the screen. There are even some that look like a ball point pen, but is actually capacitive.

Under display settings all the way dow youll see a box for high touch sensitivity. Maybe that one will make it work

Wow! I stand corrected and humbled! He definitely mentioned "conductive", but all the objects he used were everyday objects! I even tried with a pen and it worked! Didn't even have to enable the extra sensitive function. Gonna get a milk bottle next to try, haha! :laugh:
Are you using any screen protectors (film or glass)?
I know on mine, it's a matte finish, but they say that gloves and capacitive pens would still work.
Hi...new to this forum, so advanced thanks to all the tips, allowing me to give my encore new life.
Running CM10.1.2, stable build. Downloaded a stylus writing app (Papyrus), since I thought I could use my Nook to take notes at work. Issue here is that the stylus I bought works fine on my friend's Ipad, but I can't write worth a damn on my screen.
I have read a lot of threads on capacitive styli, and have some on order, but I also started looking at screen calibration and the sensitivity of the screen as well (this really could just be a hardware problem).
Question...I'm looking for the RTFM on shell commands to see if there is any way to improve the sensitivity, as well as calibration (I know there's an app on Play, but I don't need an app, do I?). Seems as if I can't find any info on either, and it's been a long time since I've worked on Linux. Only got one hit on "calibrate", talking about adb commands, and renaming the
Are there any settings to help this out? I booted into TWRP, and there doesn't seem to be anything in there, and there's a bunch of settings in "developer options", but I have to start googling those, to see if any fit the bill.
If anyone can point me in the right direction, I would be extremely grateful. Perhaps this belongs in the developers forum?
TIA...Eric
There is the nook screen recalibrate app but on my nook a stylus had never worked well. Just the hardware they used.
Sent from my ADR6410LVW using xda app-developers app
Thanks for the reply...I'll look into that app, but I have a funny feeling it's the hardware as well.
Funny thing is when I use my finger, the writing comes out better than when using the stylus. More capacitance in my finger, I suppose :laugh:
Hi
I have a nook simple touch - 1.2.1 firmware not rooted yet, I only want to use it as an e-reader but the ghosting is awful compared to my wifes kindle of the same generation (non touch).
I've been trying to look around and find out what I can do, is there a way to force it to refresh every page, some searching seems to suggest the issue was better on older firmwares, why B&N didnt include an option like amazon to force refesh every page who knows (that's not enabled on my wifes kindle) - the Kindle is just much easier to read in direct bright sunlight but I'm sure theres some tweaking that can be done to improve it
I have to say I am surprised by your description of your NST. I've been paying close attention to mine today while reading and I may be losing my vision but I can't see the ghosting you are describing. I've always felt the native Reader and its default settings worked really well. In some other apps there may be issues with ghosting, but not in the reader.
I'm running FW 1.21 also and while I have rooted and altered my device a lot, to my knowledge I haven't done anything to the functioning of the Reader app. Are you sure you don't have some kind of hardware issue?

It could be a hardware issue but it's well out of warranty, I do notice the ghosting on the kindle too so maybe im just susceptable to spotting it and having it irritate me, just wondered if there are any tweaks to control thow often it refreshes as its ok once it refreshes the screen

Seemed to be very complex, so I went for root and under there is the option for how many pages before full refresh
also installed cool reader for good measure and very happy - problem solved

Excellent! Your rooting method must be different from mine but now we're both happy
Good job, @nmyshkin!
Thanks everyone, my main concern was rooting would stop it behaving like an e reader but relaunch I a great launcher and the default options for home and library mean I have best of both and importantly control over the refresh as my nook does appear to ghost far more than a friends on comparison, for the £29 paid over a year ago the nook is awesome
Comparing my nook to a friends the contrast looks really different so maybe this unit wasnt calibrated right - i'm now looking for a contrast adjuster to see if that solves me needing to fully refresh the screen so much as that will be using more battery
Is there any way to increase the screen sensitivity on the T280? I've only found one mention of the issue after thoroughly searching Google, with no suggested fix.
I'm comfortable with modifying system files such as build.prop and such, I just have no idea where to start!
The issue:
This screen is really slow to pick up touches, especially from a stylus.
When swiping (eg for pattern unlock) contact is often broken.
Even using my finger, when selecting text it's difficult to move just one letter at a time.
In handwriting/drawing apps, resulting text is extremely angular and jagged.
Here's what I've tried:
Changed "mouse sensitivity" in the settings (minor improvement)
Used 2 different screen calibration apps (minor improvement)
Installed debloated ROM (only one available; no improvement)
Removed some unnecessary system apps (will be removing more to free up space....)
Disabled settings that affect device speed such as animations
Several different stylus types (the most expensive work worst )
So, is anyone else finding this an issue? Is there a fix I don't know about? Is/are there a kernel tweak or something that will speed up screen response time?
I bought this tablet in part so I could use it for handwriting input using a stylus on a larger screen than my teeny S5. Unfortunately, the screen response is far too inconsistent and ...well, slow than I'd expected.

Unfortunately the drivers or the touchscreen hardware itself for the T280/T285 is not that good. I have a drawing app that I created myself and the touch event update rate is so slow it creates jagged lines. Best case is that it is a driver issue and we can fix it in the kernel, worst case the hardware just sucks and it is what it is. On my OMNIRom 6.0.1 SM-T285 device touch response is actually ok, it is the update rate and precision of the touch which is a problem.
Thank you so much for the quick reply, and for understanding what I mean.

Congrats on getting most of the bugs out of that ROM! It was SO disappointing to read the "fine print" on your OMNIRom and discover I couldn't use it, as it looks pretty sleek, but you're helping others immensely with your work.

Hooray for drivers being a possibility! There's something can be done about that!!
Do you find that the lines aren't quite as jagged running OMNIRom as with stock?
How would someone find out whether it's the hardware or the drivers?
Are the differences between 280/85 so extreme that I can't try anything on my own?
Is there anywhere I can "sign up" for testing any new tweaks or ROMs or kernels?
(Update on the issue: I ran the "screen calibration" test again and it says it's taken another 10ms off the response time. Not sure if I'm imagining it but it feels as if it's actually faster...)
I was also thinking, would the DPI have anything to do with the jagged appearance? Between this tablet and the 2 others I was looking at (both Galaxy - previous 7-inch and 9-inch) those had much better DPI ...or am I thinking of resolution? Those aren't the same thing, are they? In any case, it's worth checking into whether fiddling with the DPI might do any damage.

We will need someone to tinker with the kernel sources to found out. For the SM-T280 someone is working on making the kernel sources work. Unfortunately, though annoying it isn't really on the top of my list right now.

Based on the software codepath, DPI shouldn't really affect touch performance.
I wound up returning it and picking up the 7" Galaxy Tab E Lite (SM-113), which seems to suit my needs much better. While it's much more limited in some ways - no custom ROMs, limited to KK4.4.4, same small internal storage issue - the screen response is WAY better and I can get around the annoyances (largely - no, SOLELY - due to all the things this forum has taught me over the years. :highfive:

Similar issue
Hi,
Was wondering if anyone with these issues also experienced this: While the tablet is on, when watching something for instance, if the touch screen isn't used for a bit (say over 30 seconds) when I first press it it doesn't respond at all, to get it to wake up I have to press quite firmly, usually several times, before it starts working. Once it does respond I can use a much lighter touch so it doesn't seem like a screen protector or overall sensitivity problem, it's as if the screen goes into some kind of sleep mode becoming much less sensitive.
Anyone know about this/how to fix it?
Much love,
Tom
