No reboots here either, but as with all roms including stock, random lag when activating apps- It can be near instant, or nearly ten seconds later to register. Two apps that show this are Dolphin and Tapatalk. Others do as well, but I use them more than others. Dolphin seems the worse though, from the point the app is activated, to the point anything can be done. Still seems weird how pressing an icon can take many seconds to register. Edit: Pressing an icon and watching the actual gray background reponse take place seconds later is wild. Not even the infamous Gtablet did that.

No rom yet fixes this, so must just be the way it is. Still odd how GTA Vice City locks the device up now and you have to hard restart with the power button. GTA 3 does not do this, nor any other app tested so far. Just Vice City.

At least CM 10.1 does not have the awful stutter in games that stock has :)

Erm, it wasn't intended to be rude, I was just pointing out that you shouldn't expect a Nook HD to be as fast as your Optimus L9, you gave the impression that you were surprised it was slower - I was pointing out why you shouldn't be. Sorry if that caused offence...

Were you using the correct build for the version of the ROM you were using? Because nonmatching versions cause all manner of hell to break loose - although the result is usually a bootloop. Carbon's TabletUI (mode, not mod, it's AOKP based...) works perfectly and is my daily so that might be worth a go if you want to use it.
[Nook HD, HD+ Android Development] Jack45:
FWIW Dolphin opens, and executes tasks rapidly on mine. Mentioning this because it's apparent that there are factors specific to one's device environment that affect performance, rather than a particular anomaly being universally experienced. And so, the hunt for the interfering culprit(s) begins.
[Nook HD, HD+ Android Development] robertchow:
an app perfect for testing the performance of your device

for anyone wants to test the performance of his device, ebookdroid is a perfect app

https://play.google.com/store/apps/details?id=org.ebookdroid

ebookdroid 2.0 can open several pdf ebooks simultaneously.

In the app performance setting( under all setting) ,set pages in memory to 1 ,then open three or more pdf books, quickly switching and scrolling among these books can easily crash the app.

to be able to switch among these books, pages in memory must be set to 0

or you can only manipulate two books simultaneously.

Can someone manage to manipulate more than three books simultaneously using .this app?

you can easily manipulate more than three books using nook hd ,but not nook hd+

Was on 7/12, all was fine except weak wifi; moved to 7/19, did nto sense wifi difference but had spontaneous reboot and stuck at cm circle issues; went back to 7/12, no reboot yet (knock on wood).

I only do light-duty stuff so cannot tell performance difference. TO me the bottleneck is network bandwidth. WIFI seems on the weak side (at places where my laptop gets half strength, the HD+ would often fail to find a signal) but that's probably mostly hardware.

The thing that bothers me the most is standby power consumption. I have turned of as many apps as possible from launching at start-up, disabled GPS use (still allow wifi locations, just to make the map apps useful), etc., but as the most recent sample, I fully charged it at around 10pm last night, checked (ES task manager) that only 9 tasks (system stuff + Y!Mail) running and closed the magnetic cover (Nook official) to put it into sleep (with 100% power); then 7am today I opened it and the power is at 93%! The only performance setting I've changed is to allow bitmap purge; the governor and I/O schedule remain default.

What did I do wrong? :confused:
[Nook HD, HD+ Android Development] cuoreesitante:
I read that the latest version of gmaps was updated to fix the no bug on devices that have no gps chips.
[Nook HD, HD+ Android Development] dbrickg:
Hmm, that seems about like mine... I don't watch it that carefully, so I might be getting a bit more or less. I'd just assumed that 7% loss overnight was about normal. I'll try to remember to keep better track of my battery next time I charge it.

Edit: Looks like I was wrong. My overnight power consumption is more like 2 or 3 percent. I watched it last night, had it charged to 99%, this morning it was at 97%
[Nook HD, HD+ Android Development] janky_hanky:
EDIT: Nevermind. I ran Play store updates for Google Search. Voice Search is now working.

New questions.

Long press on the PIE magnifying glass button does not work. (But longpress on home does.) Is there a way to fix that?

PIE control seems to be missing a lot of customizable features I've seen on youtube. I only see basic settings for trigger spots and size of the pie buttons. Are those other features not available on the CM version of PIE?
[Nook HD, HD+ Android Development] conan1600:
I'm not. Sounds like the driver for your mic is wonky or something is wrong in your mic hardware system. Did it work pre cm? If it worked before I'd wipe and reflash personally.
[Nook HD, HD+ Android Development] howlep:
i have noticed that mine reboots every 6-12 hours, but the uptime does not reset. :(, so the uptime may not be a valid indicator of a reboot.
[Nook HD, HD+ Android Development] old_fart:
Mine is working also... . com.google.android.googlequicksearchbox version 2.6.7.721924.

hmmm. go into 'rom manager' and do the 'fix permissions' step.
[Nook HD, HD+ Android Development] janky_hanky:
Thanks for the help. Voice Search ended up fixing itself.

However, has anyone gotten longpresses to work in PIE control? Only the Home button seems to accept a long press. I'd like to longpress on the magnifying glass to do a Voice Search.
[Nook HD, HD+ Android Development] dbrickg:
I just noticed mine do that "soft reboot" thing this morning. I thought we'd gotten rid of that a month or so ago. Last time it was due to google maps constantly trying to use gps for location. I seem to recall we were getting thousands of calls from google maps in logcat output. Now I'm not seeing that. In fact, I'm not seeing anything remarkable in logcat. As far as your observation about uptime, that's right. It doesn't really reboot. It's more like it just logs you out of your current session and starts another one. The only way I could tell that it was happening, aside from actually catching it in the act, was to look at "recent apps". When the soft reboot happens, all your previous "recent apps" disappear.
[Nook HD, HD+ Android Development] joe.stay:
Is it normal when you boot up your nook hd+ that it shows the nook screen first (for about 1-3 seconds) and then it switches over to the cyanogenmod boot screen?
[Nook HD, HD+ Android Development] MechaGen:
Yes, that's normal.
[Nook HD, HD+ Android Development] spartan4585:
yes. boot nook screen, off centered cyanogenmod logo then correctly centered logo and lock screen.
[Nook HD, HD+ Android Development] conan1600:
Hey guys I have a question. I can't remember from install so maybe one of you guys can check. Is zram enabled or disabled by default on this ROM? Thanks
[Nook HD, HD+ Android Development] MechaGen:
It appears that it is at 18% by default.
[Nook HD, HD+ Android Development] sqs1shu:
It happened to me but it stopped after I did a 'clean' install: format /system, factory reset, install 7/19 ROM and GAPPS. Only issue was that google restoring my apps threw some error, but that was due to old google play store app, I believe.
[Nook HD, HD+ Android Development] renthispace:
In case anyone here is interested like me in having a working SD card reader with the nook, this guy at amazon got my car reader to work properly (previously dmesg reported that it was asking for too much power) http://www.amazon.com/gp/product/B00A81ISJ6/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1
[Nook HD, HD+ Android Development] timboroks:
Any fix to random reboots?
[Nook HD, HD+ Android Development] DeathEvil:
did you messed with performance settings? from what I gather this rom is stable, and should not produce any reboots
[Nook HD, HD+ Android Development] dynamorphic:
My voice search isn't working either.

Hi, I've also experienced the same problem. When I press the Voice Search app it says "Unfortunately, Google Search has stopped". Do I get the apk you mention above? Lastly where is rom manager you mention? Thanks for the assist.

Update:

Scratch that. It looks like the google search update fixed it
[Nook HD, HD+ Android Development] timboroks:
Not at all. I dont touch anything that I dont know lol. Mostly happens when i listen too music too.
[Nook HD, HD+ Android Development] sn4nook:
Could you elaborate? This does not seem to have a power source.
[Nook HD, HD+ Android Development] renthispace:
If you look back to a post I made regarding my card reader not working, verygreen responded that a non powered USB hub to 'hide' the card readers power requirement. Its odd that the card reader says that it needs a lot of power when it really does not. Not sure what the limit of something that actually will draw too much power. For me, a card reader is all I want to use.
[Nook HD, HD+ Android Development] dbrickg:
This seems to be happening regularly again.... Maybe I'll try reverting to an earlier build.
[Nook HD, HD+ Android Development] rushless:
That explains some things. I thought you all were talking about hard reboots and not that. I have noticed recent and current apps purged. Still, the main issue is the sometimes insane lag. I have never had an Android device sometimes taking almost ten seconds to react to pressing an app icon.

I have used other 4470 tablets, so not a normal issue. There is some funky bottleneck and seems to be at a lower level and is systemic. I have tried with a clean device and a few apps. It does not matter and was with the stock 2.1 as well. Stock 2.1 also had the "bonus" of a LOT of stutter in games- at least that is gone with 10.1.- No game stutter, but still the app start/stop lag.

If it were the 1080p, it would do it almost always, but does not. It is almost like the device is in some form of semi random sleep state.
[Nook HD, HD+ Android Development] soshite:
Cannot boot?

I followed verygreen's guide to the word, I'm always sure to follow instructions accordingly as they are given, I never stray based on previous knowledge. However, I am apparently stuck at the CM10.1 spinning logo, and another thing, the internal CWM provided in this thread does not seem to be able to format /data , I have to use the SD CWM in order to do that. I have not formatted /factory or /rom, since trying this guide, I have tried different CWM versions (SD) and different methods to wipe /data and install the ovation build. Still, no luck. It is stuck on the spinning CM logo. This is on the 7.19 build, currently, I am downloading 7.12 build to test that one instead

EDIT: would it be possible that I did not try verygreen's new SD card format? Where you manually build the partitions? I used `dd` for the process

EDIT 2: It appears the 7.12 did not work other... not sure what is stopping it from booting, I used sdcwm to make it wipe /data and everything. One thing that may help, the spinning cm logo does not appear to adjust its resolution, it remains skewed and enlarged..

EDIT 3: Tried TWRP. Did not work either. I don't understand what could possibly be happenning here. Never had this happen before. The odd thing is it happened on the Carbon ROM as well so it is something to do with the installing process. I managed to wipe data with a different version of CWM (early7.2) but otherwise TWRP and CWM cannot mount or unmount data. Does anyone have any idea what it could be?
[Nook HD, HD+ Android Development] howlep:
let me know if you find a version that doesnt suffer from the soft reboot syndrome as much. apart from that, i am not sure that i see the lagging that people talk about :). but now that I have said that, i am sure that it will start happening.

thanks
[Nook HD, HD+ Android Development] renthispace:
And I find it odd that with the same hardware and rom version, people can have different experiences. No soft reboot issues here and no odd lagging.
[Nook HD, HD+ Android Development] dbrickg:
Installed the 7/12 version yesterday, but I've had at least 2 of the soft reboots since then.

And, like you, I haven't noticed the lag that rushless mentions... certainly nothing like 10 seconds between touching an icon and having the app start.

---------- Post added at 12:28 PM ---------- Previous post was at 12:27 PM ----------

I imagine the differences are caused by some conflict of apps and/or rom
[Nook HD, HD+ Android Development] foolforfood:
For the people having sporadic lag and soft reboots, have you tried changing the minfree settings to something stricter? I had the soft reboots until I did this.

As for the lag, I've only encountered this in one app, the Kobo app. In any other e-reader page turning is smooth, but in Kobo it's crazy laggy and stuttery. I've changed the scheduler to noop and off seen some improvement, but still quite bad. Anybody else seen something similar?
[Nook HD, HD+ Android Development] cuoreesitante:
Can you please elaborate a bit on how to change the minfree settings?
[Nook HD, HD+ Android Development] foolforfood:
I'm not sure how to do it manually, but I use autokiller from the play store. I use the optimum preset and haven't had an issue yet. Mine's been up and running for 3 weeks now with no soft reboot
[Nook HD, HD+ Android Development] MechaGen:
I'm on 0716 and haven't had a problem with reboot, but the lag issue was driving me Nuts! My wife's NHD+ is running 0613 and she has not complained once, so I started looking into her settings. Main deference I noticed is that 0613 doesn't have zRam options and her I/O scheduler is set to CFQ. I set mine to the same, zRam to off, I/O scheduler to CFQ and things are much better.

If you change I/O scheduler remember to check "set on boot".

That seems to be the same issue I am getting with bokbokan's hybrid ROM. Several "Too many open files" entries in logcat and then a soft reboot.
[Nook HD, HD+ Android Development] NicoleC:
Any known mitigation for this?
[Nook HD, HD+ Android Development] jbbandos:
Unfortunately nothing yet. The fact that it is happening in two CM10.1 based ROMs with a different implementation might point to a basic issue of CM10.1 and the Nook HD+, possibly some kernel option.
[Nook HD, HD+ Android Development] old_fart:
.

With the release of Jelly Bean 4.3 ( and the dev community is working on CM 11.3 ? ), there is talk about TRIM and FSTRIM. Our fantastic rom cooker, verygreen, is probably reading all about it . . .

How did you get this to work in USB mode? I'm not having any luck. Tried the sixaxis app as well as USB/BT joystick center.

Using the Nook charging cord with the USB female to female adapter and forced USB mode.

Enlighten me if you can. :) thanks.
[Nook HD, HD+ Android Development] dbrickg:
I grabbed a logcat just after mine did a soft reboot yesterday evening, but I didn't see any "too many open files". Not sure what's going on with mine. I tried removing both Maps and Earth, thinking they might be doing stealth gps lookups, but that didn't help.
[Nook HD, HD+ Android Development] dbrickg:
Agreed. I'm not too terribly concerned about any problems with 10.1. since I'm sure 10.2 will be coming out soon. And then we'll have a whole *new* batch of problems to worry about :-\

media draining battery

I too am having major issues with this and battery life has anyone figured out why media is using so much... I thought it was basically a download manager and media scanner, it isn't downloading anything and I don't have any media on my nook for it to scan...
[Nook HD, HD+ Android Development] cuoreesitante:
Interesting, I'm not seeing anything like that. Did you try starting from scratch as far as apps go? It's more than likely that it's a specific issue with what you installed.
[Nook HD, HD+ Android Development] spoonman326:
Thanks for the suggestion, using CPU spy I realized it was on the wrong governor somehow and it never went into deep sleep. It still doesn't explain the media app using so much battery however. Maybe I'll do another clean install if the battery is still bad now that I switched governors.

What is the host OS ? For Linux, the solution is to install dvfs with mtp support. For others, I don't know, but you might try to search the answer for stock Nexus device, the answer is usually valid. As far as I remember, it is intended design, cause USB mode might lead to data corruption. Another solution is to use the free airdroid

lagfix to compensate for lack of TRIM

I haven't been able to find anything concrete on this issue, but seeing as google just added TRIM support in 4.3, I imagine cyanogenmod hasn't had it either. The OMAP4470 doesn't appear to be on the blacklist of the lagfix app, but I have not yet tried it myself (chicken). Has anyone looked into lagfix as a potential solution to lagging devices?

This would account for the wildly different experiences with lag on this device. you don't have to fill your storage to see the issue, just rack up enough flash storage I/O and you'll use up the unused blocks on the eMMC and start to slow down as it has to reclaim old ones. The more I/O you do, the sooner you see the lag.
[Nook HD, HD+ Android Development] leapinlar:
All I know is I helped a user try to recover his bricked HD/HD+ after using that app. Use caution.

Sent from my Nook HD+ running CM10.1 on emmc.
[Nook HD, HD+ Android Development] SCWells72:
This definitely seems to have helped on mine, at least after a short time trying it. There are still apps that consistently cause lag including Flipboard and Zinio, and it seems like they didn't on earlier builds, but for the most part things seem improved. I'm still convinced that while we probably won't be able to eliminate lag entirely with only 768MB of free memory and a GPU that's intended for a 720p screen, there's probably some resource leak somewhere plus some system settings that will make things much better for everyday use across a wider range of apps. That's my hope, at least!

I'm still getting a ton of soft restarts. Today I went to pick up my tablet, and it was burning up, stuck on the CM boot animation. When I shut down and brought it back up, it had chewed through the entire battery (was at 98% when I set it down earlier this morning). It seems to restart randomly -- I haven't found any consistent cause. Yesterday it restarted when adjusting the volume while playing Candy Crush, the day before that it restarted while flipping a page while reading an issue in Marvel Unlimited.

I'll install logging tools to see what's up. Tried turning off GPS (saw that was a suspected cause in earlier posts). Anyone else having issues still? I'm on the 7/19 build.
[Nook HD, HD+ Android Development] rushless:
The CFQ setting and limiting background tasks to three has seemed to have made things less laggy. I had two freeze events and one resulted in the need to hold the power down to turn off the device.

I have had that happen with other roms as well, but seems random.

In spite of this, performance is MUCH better than stock. Such perhaps the price is mainly the 768 ram and older gpu pushing data to 1080p.

That said, hi def video in general plays back great on this device. Very's and other dev efforts are greatly appreciated :)
