black screen & freeze after reboot

So the only problem for me is that I get a "black screen" issue 5-7 times a day, so I have to reboot the device. And after it boots, it freezes while showing SD mounting icon in the upper left corner of the screen. May it be caused by the SD? It was absolutely fine before I flashed JB. Also have anyone got rid of driving-crazy issue with not being able to wake up the phone's screen?

Thanks.
[HD2 Android NAND Development] Fox_in:
I agree that this issue is not appears with all devices, seems it depends on many params. However, JB now looks like very earlier alpha. Yesterday I went back on ICS 2.7 and it is very fast comparing to JB (ohhh, before JB I thought that ICS is slow [comparing to GB] but now I know what is really slow:D). Imo version 2 of JB will be fast enough with any set of params. But not now.

Do not forget that CM10 is beta now and it may contain a lot of issues. I like JB interface but when I reverted on ICS - I dont see any problems.

Totally, I think that the main problem is that we are storing on SD whole /data directory. This dir contains not only apps but a lot of small files. Ofc, plain speed from sd card is pretty fast. However, on small files this speed falls down in lot of times. Imagine, what happened when 2-3-4 (or even more) apps at the same times tries read/write a lot of small files? I thought that it is the main problem of DataOnExt type of install. It can be solved by placing on sd-ext not the whole /data but only some subdirs of it which contains heavy-weighted apk's and other large files - this will save space on nand and provide us to get the real speed improvement on r/w files on sd-ext partition.
[HD2 Android NAND Development] circuit85:
Hi tytung, just as a suggestion, for DataOnEXT, i would suggest the mounts be created on the linse of sumthing like,

1. move all GAPPS + max possible stuff to EXT out of ROM so that we have minimum SYSTEM partition size and a bigger NAND data is available.

2. Only DALVIK-cache to be mounted on the AVAILABLE on NAND data.

3. I dont know if it is technically possible with INITRD to create priority based mount points, where, dalvik uses NAND until it is full and then if required, start using EXT for dalvik as well.

with this, we can probably get the better of both options.

Also on V1.1, i faced a lot of lags and ANRs with DataOnEXT (second option) on EU HD2. I have a Class10 16GB.

as a solution, i did try to reduce the SD-CACHE to 256K and deadline scheduler on SMARTASSv2. and lags have reduced largely. So may be a larger CACHE was creating delays to manage bigger chunk of data and resulting in a bottle-neck when multiple apps try to access SD-CARD.

my 2cents to add if it helps in development in any way. Thank you for keeping the Beloved HD2 alive and rocking.

Formatting with SD Formatter, 32K clusters and a 16K read-ahead buffer did away with 99% of the lags in my case.

Very stable and fast but interrupt load?

Thanks for this awesome rom!

But I have to report a strange "bug":

Sometimes I get a huuuge lag when switching apps / using the device.

When this happens the IO interrupt load goes to full (Developer Tools->CPU Load->Blue bar is veeery huge).

I installed the rom with NativeSD and my SD speeds are 33MB/s read, 20MB/s write according to SD Tools.

Any Help?
[HD2 Android NAND Development] NYLimited:
You know, somehow I really doubt that would fix his problem (but eventually it will wear out his NAND memory). :cool:

Huge lag when switching apps

+1 I started having this issue a day after switching to Native SD mode. I tried fixing permissions, freeing up more apps memory (> 180M)

I noticed 99- 100% CPU loading @ 998MHz, even several minutes after a cold boot. I've had to switch back to the Tytungs's last CM9-ICS build for my daily use.:crying:

Has anyone else noticed that if you have a headphone plugged in that Google Search will start all by itself? Like it was getting a microphone input trigger? I've tried multiple headphone cables and they all do it. The same phone running ICS does not have this issue...
[HD2 Android NAND Development] kcfong2:
I have flashed between the three options of this rom since Tytung released it, and I've found the NANDs (option 1 or 2) to be the fastest (from a UI experience). NativeSD has proven to be a bit more troublesome. At first (from a reboot), it runs very smooth, and very fast, but after a bit of heavy use, I notice that it really starts to lag, and the "load" as you put it, is unbearable (hitting home key queues up, and then blam, they come all at once). I can almost always get it to "die" to an unbearable slowness by going to settings->apps. It takes a long time to load the contents of downloaded (albeit, I have a lot, but NAND is really fast), and swiping over to ALL takes forever.

As for the wired headset triggering Google Search... I do NOT get that. In fact, I use my HD2 at the gym daily, and have a set of Bose earbuds plugged in... never had a problem with Google Search coming up. I'm on a TMOUS HD2 in California btw, but it looks like you're in the states too, so I'll assume you also have a TMOUS HD2.
[HD2 Android NAND Development] hutc:
my partition size

my partition size is 400mb system. i mean to say is the bug active due to activation of the app2sd function or is it due to the

sdext4 partition altering something,you have no idea i was not able to hear anything when some one called me thought my speaker gone wrong and then i read tytungs post about this and flashed the zips he recommended they worked on his ics and jb rom,but not on sense 3.5 roms so had to flash data2sd zip for eclipse beta rom.then correct permissions,this made it right i checked the sound and it came back.

i wonder what was common between those roms other than both using ext4 for data.is it compatibilty for the ext4 or is there a bug thats the reason why google went to complete nand without sd card
[HD2 Android NAND Development] adell_:
I think Google has never used SD-Ext. Also, if there is a bug, they are supposed to fix it.

NativeSD vs. NAND

Thanks for your reply.I do have a TMOUS HD2. I switched to NativeSD from NAND because another user said that another issue (HOME h/w key stops working] was fixed by going to NativeSD. BTW I noted a BIG difference in boot-up time 1:15 for NativeSD and >2 Min for NAND. So I guess for now I'll stay with ICS for daily use and wait for 1.2 JB...

I am currently running Nexus-HD2-ICS-CM9-HWA-v2,7 which runs great, so I have flashed using the same process as before i.e flashing a CWM ROM. my sd card is not partitioned as the previous install did not require this. I gave given it plenty of time to boot up 20mins plus.

Again you dont tell me which way you choose in the Aroma installer the 1. nand 2. nand-dataext 3.nativesd which one ?? The 1. nand need a big partition 350mb on your phone (not sd card) that you can do it with Hd2 Tool kit http://xdaforums.com/showthread.php?t=1090783. the second 2. Nand-dataext it needs an 4ext partition on your sd card that you can do it with mini tool partition wizard (google it) and for the 3rd Nativesd you will need the 4ext partition on your sd card but as primary one. You can look at this tutorial http://xdaforums.com/showthread.php?t=1881205.

[HD2 Android NAND Development] davidgiga:
Thanks for your link.:) I already tried different cache sizes. My SD card has a read speed of about 80 mb/s (rom toolbox), 60 mb/s (sd tools). The write speed is also very high.

But my HD2 is still very slow (e.g. I swipe to the left in the app-menu and the device freezes for 10-20 seconds. In this time the io interrut is high but the cpu load is not high at all)
[HD2 Android NAND Development] NYLimited:
It was worth a shot - I don't know what the difference is but at this time I have nearly no lags using the DataOnExt option.
[HD2 Android NAND Development] jinharry:
Still really laggy

I tried a few changes to the cache and tried a couple of the preset Memory Manager settings - no significant change. Thanks for the info!
[HD2 Android NAND Development] kcfong2:
I have found NAND to be very stable, and I use it as my daily (and I'm a heavy business user of this device)... mail, word processing, music (at the gym), camera, contacts, phone... all in a typical day.

I can tell you, I've NEVER had a problem with the Home key not working... in fact, I haven't heard of such a thing (but I didn't search for it in this forum). I have a Sandisk 64gb Class 10 card I got off of Amazon, and found that it just didn't cut it for me as a NativeSD install... it just got too overwhelmingly laggy. But NAND with either Link2SD, or NAND+SDEXT (option 2) work fine, and it's smoother (more responsive) than Tytung's ICS (at least for me).

I'm not sure why you're having problems with this ROM on your TMO HD2. I've got a couple of spare HD2's that I've flashed, and they all work identically. In fact, one of my employee's also has an HD2 (we bought them en masse), and his works acceptably with this ROM too. What brand, speed and size is your SD card? And when you flashed to NAND, did you partition the recovery correctly?

Here's a partial list of the "major" apps I've got installed: Apex launcher (also Nova), OfficeSuitePro, FancyWidgets, WidgetLocker, MissedIt, MXPlayer, Pandora, Ubermusic, Maildroid Pro, TEAM Battery Bar, Handcent, Calengoo, MuteOMatic, HideCallerID... all business related, and all memory hogs, and this phone works fine with Tytung's ROM.

Send me a PM, and we can take this topic offline if you want to continue to pursue this ROM on your device.
[HD2 Android NAND Development] MTN_HD2:
i had this issue too (home button not working) . it doesn't happen all the time , some times it doesn't work

i had to switch back to tytung's ics . i have a class 4 sdcard and it says my read speed is 7.1mbps ... idk
[HD2 Android NAND Development] kcfong2:
ny_limited,

That was a good write-up. Very informative. Just FYI, I've tried tweaking the SD cache size using SD Booster. My default was set to 2048. I tried caches from 512 to 4096kb on my Class 10 64gb. I wasn't getting astounding results, but I did find 2048 or 4096 proved to be the fastest (when measured with SD Tools). I got on average, writes of about 15mb/s and reads varying from 24.9 to 45. From a UI perspective, I couldn't notice any change in the ROM's responsiveness.

I share the same problem that another poster here experienced, that is, when going to settings->apps, it really lags to bring up the downloaded apps, and lags even more swiping to the right to see running, or ALL. I just gave up and went back to NAND+sdext (opt 2). Option 1 with Link2SD also works fine. Both opt 1 and 2 are smooth, and so far, I haven't experienced the lag of NativeSD. Since NAND+sdext only writes the data to ext4, I guess I don't get the lags from read/writes of the system component on the SDcard that nativeSD would be doing. Also, backups, flashing, etc are easier with NAND, so, aside from not being able to dual boot into WP7, I find no advantage to nativesd for me at the moment (other than knowing that I can do it ;) ).
[HD2 Android NAND Development] hardav:
The penny has dropped, checking the ICS installation, guide uses a 170mb partition so yes I need to change this to 350, how will this large partition affect the phone performance.

Cheers

Dave
[HD2 Android NAND Development] NYLimited:
Thanks, but that post was the short one, the abridged version, so to speak. Not sure how many read all of posts 1-3. :laugh:

As for the buffers - the 64 GB card should be at least once formatted with SD Formatter (yes, that will wipe everythig from the card!) I am assuming it will assign 32 KB clusters to it (I don't have one so cannot say for sure). With 32 KB clusters try a read-buffer of 16384KB for a day or so - you may like what you find though I don't have any current benchmarks on it. Anyway, the UI feel is more important than the benchmark result.

I have not played with NativeSD thus far but some functions, such as the Android Apps function, take their sweet time scanning all the apps on the device. Some other apps, like ROM Toolbox, build a database and load extremely fast. Another performance hit comes from the Android browser (and most Android browsers) because the storage schema used by the browser consists of the cache as the unstructured web cache storing image and media files and two SQLite database files; webview.db is a database for application settings and preferences and webviewCache.db stores an index to manage the web cache. The database files are much smaller in size compared to the cache but the web cache writes are mostly sequential with reuse of the same address space over time; SQLite exhibits a high degree of random writes and updates to the same block addresses. Since by default the database writes are synchronous, each write causes another delay. We need more 'considerate' programmers. :)

Apologies for the off-topic!
