Please help saving my Nook HD+
The screen keeps flashing (especially during video playback.) Unlike most of the others, it is not really turning on and off randomly, instead it just goes dim and bright and then turns to the original brightness repeatingly.
I can spot a pattern for these flashings: usually when the screen is trying to display a dim or darker page, it tends to flash a lot. For example, when I am using it to watch True Blood, the screen would flash badly for those darker scenes, but when I watch the Big Bang theory, the flashing would only happen once or twice. Similarly, when I use android rom like Carbon or CM, the screen usually flashes when I go to the menu/setting (but it only flashes when there is a change of page or when a box prompts); however for stock rom when most of the time the screen is displaying white pages, this problem would get much less frequent. But still when i use the stock to play video, the issue is still there
I have tried to eliminate the possible causes for this:
- Not a ROM issue: videos flicker no matter what rom I am using. In fact when I go into the CWM recovery, the screen does flash for every page change as well
- Not a video issue: I have tried different formats of video, mkv, avi, the issue still persists
- Not a charging issue: it happens with or without charging. I tried to charge it on wall and my laptop as well
- Not clashing app issue: it happens before I try to install any new app.
- Not a player isuue: i tried on MX player, mobo player, dice player, with both HW and SW decoding, all have the same issue
What else can I try? Can anyone give me a diagnosis of whether this is a software or hardware issue? Exchange for a new one would be hard for me since I am an international buyer, the shipping cost is simply too much
It's my first time shopping in the US and I surely hope this would be a satisfying experience. If the issue isnt resovled I am afriad I would have to abandon the device since watching video is my main purpose of buying it. However it would be really sad for me...
Sorry for my poor english and if you dont understand any parts of my issue, please feel free to clarify with me

I hope I am not the only one with this problem, cause I suspect it must be a software/render problem with android mediaplayer/web browser. On all flash videos I get close to transparent greyish/blackish flickering, it is kind of subtle but very irritating, and it does not look very beautiful... I wonder is there any way to fix this problem ? I think I did read somewhere the problem is that screen is 24 bit...and android is 16 bit but yeah I certainly hope there is a solution, and that is not a hardware problem...
I can for instance tell you, the brightness lightness samsung video does not have this kind of flicker...
What are the sites your viewing?
for instance youtube,.
No flickering here. Youtube, engadget, embedded videos all play smoothly at 480p-1080p. Try updating your firmware to a newer.
This sounds like the problem I'm having. Flash videos play smoothly but the top half the screen has a very annoying flicker.
It happens in all flash videos, in all browsers. Other file types play without any problem though so it's very strange
Hey! My first post here on XDA! Just got my Note and I have the same problem as described above.
The strange thing is that the flicker on the right side (or top side if in horizontal mode), is really noticeable in lower resolutions up to 720p, but nonexistent in 1080p!?
For example, watch the first 15 sec on the Cars 2 trailer in 720 p. and see if you got it.
[I can't post a link as a new user apparently, but Google it.]
Do you guys think it is a software related issue that probaly can get fixed or should I return the phone?
Please give me some advice!
Same problem.. Does someone know what to do about it?
Hello guys,
I have some strange artifacts on my screen. First time I noticed this was on youtube. it shows some strange picture tearing on the left lower corner of the screen. First I thought it was some glitch in youtube app, but later i discovered similar glitch in some flash video. I noticed that it's most visible in Anomaly HD, where allmost entire lower left corner somehow flickers. no other games or apps seem to have this kind of problem, 720p HW accelerated video plays like a charm
Is this problem caused by apps, or is it faulty tegra 2? Can I try another display driver? Anyone else encountered this kind of glitch?
I uploaded video captured on my Galaxy W - it's most visible on Anomaly HD
Try a custom from. If it does not work, you might have a messed up GPU
I am currently using overcome 2.3.1, but i had this issue on stock as well...what's bugging me is the fact that no other app or game I've tried seems to be affected
for example shadowgun, zen pinbal thd, modern combat 3...all those games are working with no problem...might as well wait for official ICS update and see if it helps.
ok another funny thing: after installing latest AOKP ROM this happens when booting (same thing happens in CWM recovery after installing CWM suggested in thread)

here is the original video, seems i somehow messed up inserting the link

EDIT:
i'm starting to thing there's something really wrong with my tab...this iswhat i have after applying motley kernel (no screen shifting on previous kernel)
Could my problem be somehow kernel related?

I have this problem too. I see it in the lower left corner of the screen when scrolling through the video wall in the youtube app. If I turn the tab upside-down in landscape mode the flashing/tearing happens in the lower right corner of the screen. However, the problem does not seem to happen in the portrait mode at all.
I'm on stock unrooted rom.
Can you try flashing cm rom with latest recovery? I'm unable to flash latest build with my current recovery. If I flash recovery recomended in the cm tgread my screen starts to scroll from the bottom to the top. If I try to flash the rom with this new recovery same thing happens when booting...same goes with motley kernel as documented in videos above. Anyone else is having this problem? I can live with some screen tearing but that scrolling pisses me off...it makes newer cwm recovery unusable for me.

It's just as esqauw said...when i turn tablet upside down bug appears on different spot ( right lower corner screenwise, left upper corner tabletwise ). I believe tis has to He somehow related to software, because it appears elsewhere on the screen...might be completely wrong off course. Any oppinions?

someone has to know what to do about that sliding screen issue
Same here
I was about to link you my thread on this but I see you found it already. I have not looked into this for a few months.
For me the problem is inconsistent so it is difficult to test. Id think if it were a hardware issue then most if not all apps would be affected. Maybe the way the affected apps are writing to the screen is triggering it. Id also think more people would be reporting the problem.
Different roms don't seem to help which could point to hardware or some low level (lower than rom?) software cause. I watched your videos of the boot screens post kernal changes and I have not had that type of problem yet. But I have not rooted or tried other roms either. This may support the low level software cause.
Your information adds support to a software cause with the artifacts appearing in different parts of the screen when rotated. I think a hardware cause would mean a consistent location on the screen.
I cant find the threads now but Ive seen mention that Samsung's implementation of the screen and Tegra 2 on the 8.9 causes a performance lag in landscape that does not appear in portrait. The 10.1 does not have this problem. Maybe this is related to that. The lack of the artifacts in portrait mode would lend support to this.
I hope you find a fix but Ive resolved myself to living with it. Although, I should probably look at warranty options before it expires.
Good luck
What do the graphics look like on this free graphics benchmark app?

I get 2281 in quadrant. lt runs smooth with no problems or glitching. but it runs in portrait mode which does not appear to have the bug.
Given that bug does not happen in portrait mode I'm leaning toward the problem being the performance lag issue I mentioned above.
Same here

Ok, so I have to clarified couple of things about lag and stuff.
1. I was played GTA 3 v1.3 with all the in-game setups at max and with frame limiter disabled. It has lagged as hell! Then, I switched the game to "Zoom to fill screen" and the game runs very very very smooth but the screen resolution became low. This is applied also to Asphalt 6 and other HD games.
2. The tablet runs smoothly in Portrait Mode. The stock launcher from 3.2 runs perfectly in portrait for me.
3. I tried to overclock up to 1.5 GHz and tried again to play GTA 3 with the option "Stretch to fill screen" and it LAGS! Tried with "Zoom to fill screen", no lag at all but screen resolution problem. Otherwise, is playable
I think all it's related to software. Hardware is quiet good. Maybe if we change the DPI the lag will dissapear, don't know
Jellybean seems to fix it
Well I tried the AOSP 10 beta 8 build and CM10 latest build and they both appear to have fixed the problem. AOSP seems a bit better performance wise so ill be sticking with that for the foreseeable future. I guess it was software after all.
I have the exact same issue with newly bought tab 8.9 on youtube app. and I didn't use alot of other apps but the apps I tried never had issues with the screen. The tab is all stock.
so, what we have concluded here is that it is a software issue or some hardware issue that should be taken care of by the warranty?!
Well it seems that it's software issue,because after flashing CM10 preview, those artifacts dissappeared.

That's great news. But that leads to another question
Do all gtabs 8.9 have the same issue using HC 3.2? So that we can say that we have a software issue only? Or is the issue related to some faulty SoCs that may show these artifacts using stock software?
I just want to make sure that it is a software issue only as I think I can make use of the warranty at the moment if it is a hardware issue
Thanks for sharing the tip

Hey guys, need a bit of help...
Been using the Z a few days now, and I'm having 2 issues...
WiFi and Bluetooth won't work together at the same time, one knocks the other off whenever I'm browsing and listening to music on my Bluetooth stereo... In the ratio of about 5:1 for WiFi:Bluetooth like...
That's one issue that's a little annoying.
Another is that video playback over WiFi is broken... If I load up a video on the YouTube app, depending on video length, the video normally freezes around the 40 second mark. If I load a video up in my browser, more of the video will load, but never the full video, could freeze 3 minutes in, 5 seconds in, but never fails to freeze.
I've reverted to stock YouTube app, cleared cache, didn't solve a sausage.
I haven't gotten to the end of a single video since I bought the device.
EDIT: Above issue is most likelyan android wide YouTube issue, if the comments on Play are anything to go by.
And that's on top of the Bluetooth/WiFi clashing that I mentioned above.
Not what I expect from a quad core device with 2GB ram like! Any ideas? Faulty handset? Factory reset? Return the handset? I've never rooted or used custom firmware ;so don't really know how to go about it, open to any suggestions to get the best out of the hardware...
Thanks in advance guys.
WiFi/Bluetooth issue
Seems the YouTube issue is an android wide issue, sorry for bringing it up.
Just leaves the Bluetooth/WiFi clashing issue where they keep knocking each other off while they're both being used.
Greetings XDA users! As you can see, this is my first post on this forum. I have registered here in order to get some answers from other users of the HTC One concerning some problems that I have experienced. I have been using the device since more than a week now, and these are the issues I've come across so far, so please let me know which ones of these you are experiencing as well:
1. YouTube audio / video out of sync
I noticed this the first time I used YouTube on my HTC One. Lip sync simply looked horrible while watching some videos. To test if you have this issue as well, you should try something like this video where it can clearly be seen in action: Link (Since I cannot post links due to below 10 post count, simply search YouTube for "BBC HD audio sync test")
2. Simple games lag / do not play smoothly
The first game I tried on my HTC One was Doodle Jump. It's a very simple game, and before purchasing the One, I have read about other recent HTC smartphones having problems with such simple games because some HTC devices don't know how to properly use their GPU/CPU in situations where games don't have high demands. If this is still the case with the HTC One, and not just some issue with my own, it is simply unacceptable. After all, a new flagship smartphone should not have any issues when playing the most simple of games that any old android smartphone can do perfectly.
Note: I have already tried to cure both of these problems by doing it with / without power savings enabled. I have also tried with / without Beats, Bluetooth, NFC and so on. Nothing helps.
Please let me know if you are experiencing these two issues on your HTC One as well.
Other issues and annoyances I have noticed, that come to mind right now:
3. Blinkfeed share bar at the bottom of the screen is very annoying, and apparently can't be removed at all. It's doubly annoying because sometimes you can hit this bar when trying to use the back button.
4. 3-dot-menu bar at the bottom of the screen in some apps. There even used to be a built-in feature in the setting menu to get rid of this, but HTC seems to have removed this in the final software versions, for questionable reasons.
5. Video camera settings such as 60-FPS-HD or slow motion keep resetting themselves each time the screen gets locked and go back to "Normal".
6. Audio issues (cracks / pops) when using YouTube (maybe other apps as well). This happens especially often with Beats turned on, but I have also heard it happening with Beats off.
7. Odd volume jump that happens around 80% volume when increasing volume while streaming music via Bluetooth. (Volume actually goes down instead of up, and the next step after this sounds much louder than just 2 "clicks" more.)
8. Wifi reception gets a lot worse when covering the upper side of the device with my hand. And by covering I mean holding it normally in landscape orientation, I'm not intentionally trying to smother the signal. This is quite noticeable in areas where the signal is not that strong to begin with, as I've experienced multiple times that I've choked my wifi signal by simply holding it that way to watch some YouTube videos. The wifi bar can jump from 2-3 bars to just the dot by doing this.
I am rather disappointed to see this thread buried on page 3 already without any replies at all. All I asked for is a simple yes-or-no answer if your device also exhibits un-synchronous YouTube playback and/or unsmooth Doodle Jump gameplay.
So I guess this either means that I am the only one experiencing these problems and should promptly return my phone to get a properly working One, or it means people here simply do not notice these problems or accept to overlook them.
(By the way, the Bluetooth volume oddity seems to have been a randomly caused bug, as it was working fine again this afternoon)
I'm having the same issue with YouTube. It's basically unusable, the sound and lip sync gets progressively worse. Tried wiping the app data, re-installing YouTube, disabling Beats. Still no luck, this is the only beef I have with an otherwise excellent bit of tech. I tried the test videos and it looked spot on.
If I watch the same videos on my Asus Infinity there is no problem, so it's definitely the phone. I'm pretty much out of ideas.
YouTube audio / video out of sync
is indeed very horrible.....
ive never experienced anything like that, are you guys running stock rom?
For me, it's everything BUT YouTube. Games, apps, anything, there's about a 1/4 second delay between the on-screen action and when I hear the accompanying sound. Audio sync is one of my pet peeves, so this drives me absolutely crazy. I can only assume there's some kind of processing going on with the audio that's causing it, but damned if I can figure out what it is. The only audio switch I've seen to turn stuff on and off is Beats, and that has no effect on the latency.
I'm running stock ROM. Friend of mine with a ROMd unit says his doesn't do it.
I'm also having issues with the YouTube...

So I've had this phone for over a year now, used and all, and it's perfect for me w/ its replaceable battery and MicroSD support. However, this problem occurred very recently and I'm very puzzled as to what it could be. I'm on a custom ROM and this happens on all ROMs that I've flashed, including using ODIN to the latest version.
When I was watching a YT video, all that showed up was a green screen (though the screen works fine) and I've tried changing the resolution to no effect. It now happens on all moving images (such as gifs) and the only way I could get video to play was to use MX Player and use SW Decoding to play back any videos.
Is there any way to fix this?
