After reading a few pages my screen background gets darker. Old text is vaguely visible. I have to turn it off and restart to get back to normal. Anyone else notice this? Solutions?
Edit.. I read that pushing the N button twice will fix ghosting..I'll try that
If that is on an unrooted Nook, BN reader has a 5 page refresh (consumes less energy, but sometimes screen gets to be clogged with ghosts) system. If it is on a rooted one, with any other reader, it shouldn't happen at all, as most programs refresh for every page...
IT is rooted,but it only ghosts when using the nook reader

Does it do a full page refresh on each 5th page. Also do you mean the core nook reader or nook reader installed from the market?
I'm going to guess he has a problem similar to what I see occasionally.
I am familiar with the 6-page refresh, and if I look very closely, I an see cruft accumulate, mostly leftover around the edges of prior text, and on the sixth page the whole screen cycles to reset the background to pure clean white. This is normal and it doesn't bother me.
Once every couple hundred pages, the screen gets stuck in a kind of negative-ghosting mode.
Basically, the cleanup cycle resets the screen to a light grey, like 75% brightness, instead of 100% white. The other 5 pages work normally. That is, they erase the old black to 100% white, and display the new text in black. So you build up 5 pages of negative-image ghosting.
Then on the sixth page, everything gets reset to solid light grey.
So far the only solution has been a full power cycle.
This has happened three times since I got my nook on the sixth of August.
This is on an unrooted nook. If I remember correctly, every time it's been while reading a DRMed PDF, but I don't know if the type of book makes a difference. I haven't read a lot of anything else on it so far.
Here's an example:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I get the same thing as iunius. I don't think the type of book matters. I get it while reading retail B&N epubs too. It seems to happen most often when I'm navigating menus or decide to share something. Something about those menus popping up and perhaps not doing a full page refresh but a limited area draw. I don't know. But it's annoying. I'm glad it's not more frequent than it is.
Yeah, I finally finished reading that page PDF and started on an epub book and had it happen again about 100 pages in.
well, I have a question

you will be able to change back and forth, but you can't install honeycomb on the nook touch.

My Xoom is getting replaced for some cosmetic damage (weird dent in the back rubber out of the box). Anyway, I have been playing with it a lot while waiting on my replacement to get here...only thing is I have spent some time customizing my homescreens the way I want them. Is there a way to backup my current setup or will I have to reorganize it again when I get my replacement? Thanks for any help.

Some people are saying that your apps and settings will be restored automatically. Not sure about the home screen configs though. I will not know until middle of next week when I sign into my new Xoom that will replace the one I have now (twenty-five percent off lucky bastard).

If you backup your contacts etc. to your google account, you will get them back on the new device when you sign into your google account. you will also be able to re-download your apps as well as they are tied to your google account also.
Your homescreens/widgets won't be saved. On phones when you're using a custom launcher like ADW or Launcher Pro, you can backup your homescreen locales, but as far as I know there is no way to do that with the stock launcher on 2.3 or 3.0.
well crap...the homescreen config is what I cared about, that sucks.
Maybe someone can help me then, because here's my main problem:
I sync my Xoom bookmarks with my Chrome bookmarks. The problem is my Chrome looks like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Notice all the favicons with no text? Well, when I sync them with my Xoom, it just shows a bunch of blank tabs without names (because I remove them in Chrome). So I went through and added most of my bookmarks as icons on one of my homescreen pages, so I can see the favicons relevant to each. It took FOREVER to do. Is there an app or anything that will let me see my bookmark favicons correctly?
I mean I'm sure it took you some time, but it takes no time at all to get rid of that text in Chrome.

Right, and I don't want the text in Chrome because I know what the site is based off it's favicon, but the problem is on my Xoom it doesn't show the text or favicon, so I just have a bunch of blank bookmarks. They work when I click them, but I have no idea which one I am clicking. The only way I can see the favicon is by going to +/More/Bookmark and adding it to the desktop manually. I need a way I can see my bookmark favicons on my Xoom to know what bookmark I'm clicking.
AFAIK there is no Android phone with an eInk display.
eInk Display swap:
I wonder if there's a device out there with a modem that would be a good candidate to replace the screen with an eInk, or at least, sunlight readable display?
The last time I looked into this the graphics driver itself would probably need replacing too, making it much more difficult than a simple screen swap. Also I was unable to get find a donor phone with a screen size to match off the shelf eink displays and also sourcing an eink display was difficult too. I need to learn more about how displays work and how I can search to get a phone and screen to match. Any ideas on this?
Kindle:
Perhaps I need to come at it from a different angle? The old kindle is eink and Android... and it has 3G... but it's hard to hack with... it wouldn't be easy to turn into a proper phone. That I will have to investigate. Any other ideas?
NookTouch:
The NookTouch would be a lot of work to turn into a phone but it's technically possible. You could go hostmode, usb hub for mic/speaker/headset and add a USB modem but that's going to be messy. To do this neatly you'd be cutting up the Nook and would at least want a low profile way of connecting into the USB port. Plus charging might then become difficult, especially if trying to do the induction charging hack. I think other avenues are better to try.
I don't think that the old kindle is android based, and besides it wouldn't be ideal as it's not touch-screen
or you could go down the 50/50 route and follow this guide:
I use a matte screen protector and using an app like Cool Reader (since I'm on Android). I change the background to a moderate to light grey and the font to a dark grey about 25% -30% lighter than black. Turn down the screen brightness to about 75% outside and 45% in doors. Then change the font by adding fonts to the system fonts to a more soothing type face like "antipasto". Increase line spacing to about 125%-150% and margins to no more than 10pt on all sides.
See the above image for what this looks like. It isn't exactly like E-Ink, but it is nicer than staring at a bright white screen. This trick should work with any app that lets you tweak the text and background colors, on iOS or Android.

I have major display problems on any CM based ROM with crazy jumping and unreadable screens.
I have tracked the problem to the display of white lines. A screen shot is OK, so its hardware - either the Adreno200 GPU or my screen.
Problem Description:
Lines (pixel lines that is) containing a significant amount of white randomly do not display. As a result the display "scrunches up" with a gap from the bottom. Any background to the app, and sometimes the desktop will display in the gap at the bottom as it has not been written over.
Note the "bottom" in this context is the button end of the phone, thus rotating the phone leads to different screen areas being affected.
Affects all the CM ROMS I have tried, with the latest CM10.x ones being the worst. There was no issue with the stock LG ROM.

Coloured triangles produced by "OpenGL Demos" app are OK
2.
White Triangles loose lines and scrunge up. I used the Demo prog as the code is the same, just a color change!
3.
Screen shot, so not a software issue. What they should look like!
5.
Google Play. Unusable. Note hte white background is OK. It just seems to be items that are layered onto the screen.
Apps with black backgrounds and grey/coloured text are fine.
What have I tried?
I have tried messing with OpenGL HW settings with no effect.
I have messed with screen brightness.
I have tried various ROMS.
I tried moving processing from the GPU to the CPU, but that completely messed the display, and I had to re-install the ROM
I haven't tried altering the refresh rate from 60hz, but cannot find if this is possible. I think its a refresh problem, but not sure. Its almost as if the white lines are sent faster than the screen can handle and they are missed during the display phase.
The other theory is that the GPU does some special acceleration cleverness for white areas the screen can't handle.
Any ideas?
Any Adreno200 settings I could try?
Any bridges nearby I could jump off?
p.s. Photos taken from the Optimus Nexus Me port here:
http://forum.xda-developers.com/show....php?t=2397696 not that it matters which ROM it is.
Obviously, it's not "soft" problem, it's a "hard" one, replace the screen.

That was kind of where I was heading, but I was concerned that an aftermarket screen would have the same problem. This screen was fine with the stock ROM, so was hoping for a magic setting change.
Thanks for the response. Really wanted to run your Zoe ROM, but that was worse.
To be honest, I wouldn't replace the screen on this phone anymore. It isn't worth it anymore.

So my galaxy s5 has been working great for the past month or so that I've owned it. I have rooted it and done some adjustments with the xposed installer, but I haven't flashed any custom roms yet or anything. So then today out of nowhere, this little stripe appears on my screen:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",

"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
So that's annoying. I took a screenshot on my phone and then moved it to see if it was the actual screen or just the picture being displayed on it. However, the screenshot shows no black stripe when zoomed and moved around so that the would be screenshotted black stripe wouldn't be on top of the actual black stripe. Then I restarted my phone, still there. I booted into recovery mode to see if it still happened when not opening the actual normal use, it was still there. Then finally I tried pulling out the battery and putting it back in, still there. I'm a little frustrated and a bit scared that I've already voided my warranty by rooting it and disabling knox. Also, the line turns sort of white when against a dark background and goes away when the screen is off. It's not the worst obstruction in the world, but the phone is less than a month old, so obviously I want it to be perfect. Any help that can be offered is appreciated.
I'm on verizon if that makes any difference.
Edit: I haven't dropped it, exposed it to heat or magnets or anything of the sort
It's unfortunate that you didn't post a full size, full resolution image. We can't make out any fine detail in your reduced resolution image. It would also have been good to know if the band is invariant in size as you make screen adjustments or display primary colours on screen. Or if it shows up in downloaded photos?
We are of course seeking a pattern or otherwise trying to narrow down the potential causes. Since we don't have much to go on yet, we can only guess, it looks to be a hardware defect. But there isn't enough information to be certain.
It would still be useful to look for a pattern in whether the band varies at all with different colours and brightnesses on screen. You can also use the dialer code *#08# and display red only, blue only, white only, black only, etc screens to get a better sense of which pixels are apparently contributing to the band.
Also try backing up the phone (to save your user files or installed apps), then revert to 100% stock firmware temporarily, followed by a factory data reset. If the problem persists it is all but certain to be a hardware issue. Claim it under warranty then if you can.

Hi Guys,
Im looking for some help on a strange issue. Ill try to provide some history.
I had a P10 plus and everything was going great then after about 6 months it would periodically just reboot as i was using it. I did think much of it as it could be an app bug. Then i was using it one day and it turned off when it rebooted the loading "hauwei" and associated boot-up animation has a purple/pink tinge to the screen. See pics attached. The phone loaded fine as normal when arriving at the home screen the again the whole display had this color tinge to it. Strangely whenever i launched any app the screen would go black. The phone would be working as i would here notifications etc and the home button would return me to the home screen but i would need to reboot. same result after reboot.
I thought i would try a factory reset to try to resolve it and now the bootup screen it the same ( pink tinge) however now it loads to a black screen. I assume it the the initial setup screen as i can here things happening when i touch the screen but cant see.
The fact i see the loading screen and the screen its responsive make me think it it not a screen issue. Also it is strange the device loaded but only went black when launching an app. Also device appears to be working behind the black screen as I can here volume up/down tone and notifications etc.
Could this be a motherboard issue?
Thanks

After doing some digging it seems i can't upload images as i am new. Whilst i understand this is to stop people just leeching i also disagree with it in situations that a user could have found a potential issue that could be affecting a lot of other. By not allowing to upload images of what they have experienced other cant be sure it is the same issue. If anything it just encourages people to go and make posts about arbitrary topics to increase their post count. More than likely if wont be helpful. Any how i appreciate communities like this so ill persevere and hopefully get my images uploaded sometime soon.
Thanks
