@All the people with unresponsive page turns: Do you use the swipe or tap to turn pages? I've noticed some unresponsiveness in general with taps but no problems whatsoever with swiping. I tend to find swiping more natural anyway.

But, is there a particular location where it happens?

Remember that the touch operates on an IR detection system, so if you are reading under a strong IR light source, you could encounter problems. There is one particular incandescent light under which I have problems, but nowhere else.

Just curious as to how that works. I have heard of resistive and capacitive systems on modern devices, but never a light based system since very early days when they shone beams of light in a grid over old CRT monitors.

I notice a problem, when I open a new book it always opening on first chapter (first entry of toc file) not on first page.

There are also lot of pictures of book I deleted directly from the kobo (.kobo/image)
And lot of record in sqllite database.

I tried to test your theory last night. I have a lot of problems with missing taps. I read 95% of the time with a LED book light. I started a new book last night and changed the tap location for turning pages (through settings) and virtually no missed taps (maybe one or two for a hundred turned pages); The first time I tried going back a page, I had two missed taps in a row, but then none going forward. I tried both with and without an LED. I believe once before I changed the tap location (in settings), and it helped with missing taps, but the problem came back and changing the settings again didn't seem to help.

I did have one case of the touch stop responding all together last night. I tapped once, and a word highlighted; after this, touch stopped working completely. I got responses to the home button, but tapping/swiping would not respond at all. I had to cycle power. This happened at least once before.

This morning, it missed maybe three taps out of 50.

I've also noticed that if I use the fat of my thumb to try and tap, it will ignore the tap. I also have problems with page tuns using swipe.

My guess it is some combination of things that is causing the page turning problem. Could be some relationship with the ePub itself. The new ePub I just read was rather large (~10MB), where normally ePubs I read are ~(.5MB). I tend to switch hands a lot, so my tapping probably isn't always uniform.

I've used a Nook Touch in the past, and don't recall having problems with taps. I was going to try it last night for a comparison, but I was so in awe of the Kobo working, I didn't want to stop.

The problem is not that the KT misses taps occasionally. That's going to happen with any touch screen, and it's not a big deal as long as it's not frequent - you just tap again. The problem is that often the KT will then double-page-turn on the next tap, meaning you have to recognize the double page turn and tap again a third time to go back a page. That's annoying, especially since it's a bug that should be easily preventable by proper firmware design. What's happening is that the KT is getting half the tap, i.e., it clearly recognizes that you have put your finger down, but not that you have lifted it up. It's obviously waiting for you to complete your gesture, and only when you tap again does it realize that you're not making a gesture (an alternate theory would be that it's actually busy for longer than usual processing the page turn for some reason, but that's ruled out by the fact that you can wait as long as you like and no page turn happens until you tap again). In that case it should single-page-turn, not double-page-turn. That would seem to me to be an easy change, but maybe there's some problem separating this error situation from legitimate gestures?

I was thinking I had no issues. But I had a problem today with the pages not turning then a double page turn. Not sure if the touch double page turn was due to a delay in reading the tap.

The problem, for some/many Kobo users, is that pages aren't turning when they are supposed to.

I personally don't have a problem with double page turns (while reading). I've maybe had 10 (a guess) in 2.5 months of reading on my Kobo Touch. Meanwhile, I've probably had > 500 (this is a guess) missed page turns again on my Kobo. I'd gladly change my occasional double page turns for my frequent missed page turns.


P.S. And I don't mean to dismiss in any way that people are having problems with double page turns.

To me it looks like a software issue.
I didn't have any problems until one of previous FW updates, when I got lots of missed taps. After factory reset and fresh update, missed taps were gone, but frequent double page turns appeared
Waiting for the next FW release, hopefully it will fix all this stuff.

Look around the edge of your screen - there's a very thin shiny strip between the case and the screen itself. That's sending an infrared beam across the top of the screen both horizontally and vertically, and being caught on the other side. When you 'tap', the sensors within the beam projector/receiver register the x,y coordinate of where the break in the beam occurrs, and depending on those coords, and whether it was a single break or a moving break (ie, swipe), the device performs the appropriate action.

It has nothing whatsoever to do with actually tapping the screen, nor how hard you tap, all you have to do is break the infrared beam.

I don't know for sure, but my best guess is that the problem with non-responsive 'taps' is probably due to the sensitivity setting of the beam-break sensors. They have to be set to some threshold above a single (or small number of) pixel(s) of the beam breaking, otherwise bits of dust or fluff sitting on your screen would cause havoc. So if you 'tap' lightly, and have relatively hard skin or pointy fingertips, the 'footprint' of where you finger tap breaks the beam could be small enough and the beam-break sensitivity set large enough that the sensors don't see this as a 'tap'. That's probably why swipes work better. And some kinds of lighting surely will lessen the sensitivity of the infrared sensors too.

That's my guess. If I'm correct, I wish they would include a 'tap sensor sensitivity' setting in the user prefs that we could adjust ourselves to suit our own needs.

Cheers

The idea of IR touch screens isn;t new and the company that supplies (I believe) the system used by Kobo has been around for a while, they even used to make a mobile phone which they used to showcase the IR technology.
I had one and it used to compensate for changing light levels and was certainly up to writing text messages at a reasonable speed. It also had swipe to unlock before Apple used it.
I've also seen them used in industrial settings so the screen wasn't affected by gloves, oil on hands etc. and they were built into a removable bezel which made maintenance/swap out easier.

Living close to beach I have to sometimes brush sand off screen to solve no touch response problem. I brush with screen down so gravity helps.

I just made my first purchase from Kobo since 1.9.16 came out and need to know how to downoad my new book from my Kobo Desktop to Calibre or directly to my Kobo Touch without syncing through WiFi because I don't want to instal this version.

I'm sure this has been dealt with before but I'd appreciate it if someone would be so kind as to tell me where to find the answer.

1.9.16 is no longer current. It's at 1.9.17 since Friday. To get it onto your kobo without using the desktop app or wifi sideload using ade which means you'll have to download the DRM epub from your purchases on the website (should be a blue button right next to the book). To get it into calibre it will have to have the drm stripped or be drm free in the first place. I can't tell you how to do that per forum rules but there's always google.
