For everyone having YouTube HD problem:

The lag and stutter have been there since Samsung's crappy ICS update, and for some reason, every single custom roms also have this problem (at least for me). ONLY honeycomb based Roms have smooth YouTube. So it's not Rom related. And you may not have experienced this issue with previous versions of this nightly, but it was probably that you watched different videos, which don't lag that much, as every video is different on this tablet. Some lag horribly, some ok, some smooth. Videos like music concerts where the camera pans around a lot lag really bad. But for videos where the camera is still and objects are moving are less leggy. And very weird thing is that action movie trailers, which move super fast are smooth as butter. So we don't really know the problem.

I don't think you guys should blame this Rom for the YouTube HD problem. I have had it in every single Rom (ICS, AND JB) EXCEPT for honeycomb roms.
[Galaxy Tab 10.1 Android Development] pucelo:
Sorry, but I can´t agree with you. Since 02/15 nightly something is going worse, same videos and same channels in YouTube, at least in my case.
[Galaxy Tab 10.1 Android Development] nakedninja42:
I've seen this stated a few times before that Honeycomb seems to be the last working OS with YouTube....

My thought here is (since it has been awhile for me on HC), does the YouTube app update to the same version as ICS or JB, or is it older build that only works on HoneyComb and below... If the latter is the case, maybe pull the apk for others to test.

It kinda makes sense because ICS and JB brought new upgrades to the application. If Google has already dropped its support for our device, it could be why some see the choppiness (its all depending on what type of video you are watching)...

Pure speculation with no actual proof....
[Galaxy Tab 10.1 Android Development] Ackoman:
Totally disagree with this post. The 13th Feb nightly has got perfect playback of YouTube HD.
[Galaxy Tab 10.1 Android Development] the^one123:
Same here definitly. This problem exists first since updating to 4.2.2.

Edit: updated to nightly 18.02.2012 and CPU is now throttling down fine for me.

So now the tab isn't so laggy at all how on nightly 16.

On weather, toggle the metric button on and off and reboot and it should show Farenheit temp.
[Galaxy Tab 10.1 Android Development] MichaelMcC:
Thanks

That worked. I did have to tap the weather after rebooting once before it switched from C to F but after that it stayed on F between reboots.
[Galaxy Tab 10.1 Android Development] Ackoman:
Strange - I've just tried 18.02.2013 and it's still bad for me, CPU never lower than 1000MHz on interactive, and YouTube HD videos and tab in general running worse than ever.

I'm back on 13.02.2013 for now........

Hi

I've been on CM10 for a while now because of the 3G battery drain in CM10.1. Does anyone know if this bug has been fixed? Thanks!
[Galaxy Tab 10.1 Android Development] alladdin:
First I must thank you pershoot and cyanogen team for your excellent work.

I done a full wipe (I deleted even sd card content) then I installed Stock UK ICS ROM by oddin. Over it I flashed CWM, CM10.1 and gapps from first page and everything works fine. I have no issues described here. HD video plays smoothly. Battery life is awesome.

Mabe I'm lucky person with good piece of hw:)

[Galaxy Tab 10.1 Android Development] oysteivi:
It hasn't. At least for me, l2_hsic keeps the tab from entering deep sleep most of the time.

(I just charge it every night and try to ignore the problem).
[Galaxy Tab 10.1 Android Development] volja1971:
I agree with you guys, the video was working fine until the 4.2.2 update was introduced.
[Galaxy Tab 10.1 Android Development] trackloading:
Pershoot, do you have plans to fix this? I'll be glad to test if it's needed... :)
[Galaxy Tab 10.1 Android Development] pershoot:
l2_hsic is supposed to be there. this is how you are able to have mobile data work properly. to make it better so it doesnt take a longer then usual wakelock, so much, we'll see. have other stuff to sort first.

[Galaxy Tab 10.1 Android Development] volja1971:
That is interesting, but what i really experience now that the videos that used to play fine on February 13 dose note play smuthly on the latest 4.2.2 updates.
[Galaxy Tab 10.1 Android Development] monkeyhybrid:
All the nightlies I've used over the last couple of months or so have been very solid. Go for it!

---------- Post added at 04:56 PM ---------- Previous post was at 04:48 PM ----------

Do you have a specific HD video you could link me to, to try on my Tab? I've not seen any lag or stuttering but maybe it's just the particular videos I am watching (they are HD though).
[Galaxy Tab 10.1 Android Development] volja1971:
Sure, i have not access to them now, but will post a link as soon as will get back home.
[Galaxy Tab 10.1 Android Development] Ackoman:
Yes, I think that pretty much sums up the main issue.

Could I also add your fix for using the HDMI adaptor with TVs that don't support deep colour and flicker as a result?

I tested a short while back ( OEM kit) and the flickering is present.... I also have seen some one else mention it too.....

Big thanks for all your work....

My tester has no issue with this.

I don't have a HDMI adapter on hand at the moment so wouldn't be able to look in to it, currently.
[Galaxy Tab 10.1 Android Development] ccsnet:
I'd be happy to contribute if you tell me what you need?

I have 1 screen that supports it and 1 that does not also tested with a blueray player with the same feature but can be on or off.

All kit is branded and the adaptor is Sammy original.

[Galaxy Tab 10.1 Android Development] _strauch_:
I have the P7310 but i have the problem like you since Android 4.0.4 i installed the us version, maybe i have to install a newer Stock ICS. But the original ICS (Hungary) for my Tab isn't out :(.
[Galaxy Tab 10.1 Android Development] tomorrowmanuk:
Just to add to the YouTube performance discussion. I've been regularly installing CM10/10.1 nightlies since they 1st became available several months ago and have had no performance issues (though there was a slight but manageable drop in performance when initial 10.1 was rolled out, I believe due to inability to use the native Samsung nvidia2 graphics libraries bundled with their ICS release or some such thing).

Yesterday upgraded from the 20130211 (4.2.1) to 20130218 (4.2.2) using the built in update function and the overall performance degradation was very noticeable with increased lag between pressing a key on the virtual keyboard to it's display, through to YouTube videos being being unwatchable (my demo clip is the latest Star Trek Trailer).

Wiped the tab and reverted back to 20130211 and the problems are gone and the performance is back in the 'usable' area again.

Thought I'd mention it as there seems to be some dispute about the validity of the various 'My tablet has slowed down since 4.2.2' claims. Just want to add that as a regular CM10 user I am also experiencing these issues and as such will have to refrain from further upgrades as it makes my tablet unusable :(:(

Should add though I am extremely grateful to Pershoot and the Cyanogenmod team for the work they are doing with this tablet, without which I would not have the joys of Jelly Bean and Google Now of which I am a great fan.
[Galaxy Tab 10.1 Android Development] Vertumus:
Hi guys,

I just installed latest built and everything is fine, but my sound is very, very low when I am watching movies or listening the music. Notification volume is fine.

Can you help me?

Thank you in advance
[Galaxy Tab 10.1 Android Development] monkeyhybrid:
I'm not disputing this is an issue, there's enough people reporting this that there must be something going on, I'm just wondering what the cause is because I'm not seeing any problems here on my Tab, running the latest nightly from 18th Feb. I tried playing the latest HD Star Trek trailer in YouTube and it was silky smooth, as are all the other HD videos I have tried. Also no problems with keyboard input (although I am using Hackers Keyboard - have not tried with the default one).

So I'm wondering if there may be an app or configuration setting causing these problems? The only thing I can think of I have altered from stock is to turn off the screen change transitions (transition animation scale set to off in developer settings). Other than that, just some pretty standard apps installed.
[Galaxy Tab 10.1 Android Development] C-o-M:
I described the cause already 7 pages ago. Something in the init process / usb handling (usb debugging?) changed that causes a lot of CPU load:

Where do you see that?

Don't see it in logcat. Also don't have issues with beeing laggy on 16th Feb nightly

sent via Tapatalk
[Galaxy Tab 10.1 Android Development] C-o-M:
It's in dmesg.

From what I've seen in the last 10 pages here (and the tab 8.9 thread), this problem occurs only if you update a system where USB debugging and/or MTP was disabled. But some people tell that it's there after a factory reset.

So actually it seems to be the other way: you always have the problem unless you update from a 4.2.1 where USB and MTP is enabled. I'll have to verify that, but I don't have access to my tab before Saturday.
[Galaxy Tab 10.1 Android Development] pershoot:
pick up this change and you shouldn't have that issue any longer: https://github.com/CyanogenMod/andr...mmit/dd1f3a89972fc814d0c590be62897ae10f430c58

make sure the drivers on the pc the tab is connected to is in good standing. failure to do so will cause instability on the tab (when connected). i linked drivers some pages back which work well (for windows).
[Galaxy Tab 10.1 Android Development] pershoot:
+1.

all works ok/decent to date (aside from the issues i listed which are being worked on). youtube HD has always been **** (since ICS). on the list to try and make better (ive tried some back with some minor tweaks which helped a lil, but not as much as i would like).

turn off the anims so it doesn't give the 'illusion' of lag wagon.

some more performance tweaking/tuning to be done in the next few days as well.
[Galaxy Tab 10.1 Android Development] Ackoman:
Hi Pershoot,

I certainly would not describe Youtube HD as **** on the 13th Feb nightly, in fact I would say it was perfect.
[Galaxy Tab 10.1 Android Development] pershoot:
lucky for you. cycle through some videos and it will become apparent that it is no where near the level it was on honeycomb (with regards to HD viewing within the app).
[Galaxy Tab 10.1 Android Development] tomorrowmanuk:
Hi tried the upgrade from 20130211 (4.2.1) to 20130221 (4.2.2) after ensuring MTP & USB debugging where enabled (on my tab they where disabled previously).

Can confirm your suggestion works. Performance is fine input lag gone and can watch the aforementioned Star Trek clip without any stuttering etc

Thanks for the suggestion.

P.S. Do I need to leave MTP & USB Debugging enabled for future updates ?
[Galaxy Tab 10.1 Android Development] pershoot:
MTP is always on by default from here on in. you cannot turn it off (you can switch to PTP if you like/need to though). make sure your drivers are in good standing (check above) or you will have issues. same for ADB if you use debugging (you may need to wipe your local keys (in ~/.android) when updating just in case, if things dont work when whitelisting)). you do not need to leave it (debugging) on.
[Galaxy Tab 10.1 Android Development] C-o-M:
Hi pershoot

I have included this change in the latest build. But there are people claiming that the issue hasn't been solved (and there are some in this thread here as well). I would try to test if the problem is there after a complete wipe (as those people say), but I currently don't have a tab to test.

OT: who do I have to contact when I want to become a device maintainer for the GT8.9? I don't think that kallt_kaffee will come back in near future.
[Galaxy Tab 10.1 Android Development] Snorchblapp:
MTP is having issues on the Feb 18 Build. Everytime I check it on, it turns off. The setting wont stick, I dont even have to leave the screen, simply changing the orientation unchecks it again. Turning Android Deubbing on then off reboots the tablet.
[Galaxy Tab 10.1 Android Development] pershoot:
no idea on your tab, but i had the same exact issue (someone else i know did as well), solved by not forcing the adb config (since i had not even been able to whitelist it yet at that stage), and instability attributed to it (that and the drivers/platform were not up to date as well on my local side).

also, there have been modifications to cortex/bionic being done, so builds may have been used in the middle of that. i still need to review their impact (if any) on this non neon platform (im not sure currently if any non neon enhancements were done (i haven't looked in there in a few days)). looks ok currently though.

Please PM me your contact information, and will see if i can get you added in there.
[Galaxy Tab 10.1 Android Development] pershoot:
you have a driver issue on your pc. if on windows, remove SAMSUNG drivers from device manager, and reinstall from the driver set i uploaded (check date on the driver folder files; not the file with P4 in it but the other one), and you will be fine.

MTP works; confirmed. USB debugging works (with saved and not saved whitelist from local pc); confirmed.
[Galaxy Tab 10.1 Android Development] pershoot:
Use the build after 18th. I'm not sure if my change made it in to that one.
[Galaxy Tab 10.1 Android Development] Snorchblapp:
Except Ive done that 3 times already, uninstall, reboot, install. No dice.
[Galaxy Tab 10.1 Android Development] pershoot:
Its a driver issue. Use usbdeview and purge it. I battled it myself just recently.
[Galaxy Tab 10.1 Android Development] Snorchblapp:
Alright, I'll give it a shot. How about the Android Debugging issue? It happens if its connected or not.
[Galaxy Tab 10.1 Android Development] pershoot:
as ive stated, use the build after the 18th (21st is up), because im not sure if my 'dont force adb config' made it in to that one and you 'shouldn't' have an issue.
[Galaxy Tab 10.1 Android Development] Snorchblapp:
Sorry to report, it's still there after a dirty flash, and still there after a full wipe (factory reset & format system) and flash. Still sorting out the drivers.

Another thing I noticed the last few full wipes I did, the bluetooth address keeps changing. What's up with that?
[Galaxy Tab 10.1 Android Development] pershoot:
i cant reproduce. all works over here (with regard to mtp/adb) and for others. fix your drivers.

im not setting an explicit MAC on BT. it should get it from the chip once connected (not sure if macloader can do BT as well or I may need to add something else in; it should work regardless of that).
[Galaxy Tab 10.1 Android Development] Snorchblapp:
Thanks for the tip, it worked.

[Galaxy Tab 10.1 Android Development] recoil1911:
So here is where I am.

SCH-i905

2/21/13 Nightly

MTP is off. If I toggle it on it will automatically toggle off as soon as I leave that screen.

MTP was off, android debugging was off when I went from 4.2.1 to 4.2.2

"dmesg" lists repeating "android_usb: already disabled" messages

My PC won't recognize the tablet any more when I connect it.

I played the Youtube videos posted earlier and the first one has choppy playback.

Do I just need to factory wipe, format /system and install 2/21/13 to clear all of this up?
[Galaxy Tab 10.1 Android Development] pershoot:
fix your drivers. follow the posts right above you.
[Galaxy Tab 10.1 Android Development] recoil1911:
I used "usbdeview" to uninstall any Samsung mobile drivers from my PC and rebooted. I downloaded the Samsung USB driver for mobile phones v1.4.6.0 from droidbasement.com and ran it as administrator. Nothing comes up after executing the binary. I am using Windows 8 Pro 64-bit.
[Galaxy Tab 10.1 Android Development] pershoot:
windows 8 you might be on your own. windows 7 those drivers work.
[Galaxy Tab 10.1 Android Development] recoil1911:
Windows 7 32-bit, 64-bit or does it matter?
[Galaxy Tab 10.1 Android Development] pershoot:
I use 64 bit so I can only vouch for that.
[Galaxy Tab 10.1 Android Development] pershoot:
I also run Ubuntu 12.10 64bit (in a VM) and it (mtp) just worked in there as well.
[Galaxy Tab 10.1 Android Development] recoil1911:
I installed the USB drivers on a 64-bit Windows 7 system which was successful and rebooted. The tablet is still not being recognized. If I enable MTP it will just automatically uncheck itself when I navigate away from the Storage -> Connect As page.
[Galaxy Tab 10.1 Android Development] pershoot:
keep trying, youll get it.

with tab plugged in, identify which entries are being used. delete the entries in device manager (SAMSUNG). unplug, and delete using app (must be run as administrator) if they are still there. reboot. install drivers. plug in tab, when it starts to install driver, quickly go to dialog, and abort searching windows update for it. it will then install locally found drivers. unplug, replug, and it should work.
[Galaxy Tab 10.1 Android Development] recoil1911:
USBdeview and Windows Device Manager are not detecting anything new when I unplug/plug the tablet in. I have tried multiple USB ports. The MTP setting is flaky. I can't manually disable it. If I navigate away from that screen or the tablet goes into lockscreen it will automatically uncheck the MTP setting.

I am ready to punt on this one, factory wipe, format system and reinstall 2/21/13. If it clears things up I will post my findings so that someone else may benefit.
[Galaxy Tab 10.1 Android Development] pershoot:
MTP cannot be unchecked. there is nothing flaky about it. you can however select PTP. windows drivers are a pain. not really the tab's fault.
[Galaxy Tab 10.1 Android Development] Snorchblapp:
I ended up deleting everything I didnt recognize. I figured worse case, it'll reinstall itself later if its something I needed.
[Galaxy Tab 10.1 Android Development] ccsnet:
Hi pershoot.... was going to do a video for you on this so using the latest build I plugged in the HDMI adaptor and powered the tab up. It hung on the spinning logo. I tried again.... got the same... tried a third time but booted first ( did not unlock) ... the tabs screen went black and nothing happened ... after thirty secs I unplugged and it rebooted the tab again.

This did at least work a couple of builds back even though it was flashing....

I know you have a tester already and don't have a HDMI adaptor your self but I really like to help....

"dmesg" no longer repeating the "android_usb already disabled" messages but now repeating "mxt 0 p", "mxt 0 r" and various "mif: usb_resume" "mif; usb_suspend" messages. Not sure if those are normal.

My PC instantly recognized (Windows 8 64-bit) and connects to the tablet now

No change on the Youtube playback
[Galaxy Tab 10.1 Android Development] pershoot:
good.

you should not have to wipe from .1 to .2. it was a driver issue in your case which was causing it. it happens (more so for me since im constantly going in and doing wierd stuff, hehe).

as stated, youtube hd is hit/miss (depending on the video/content) and has not been up to par since ICS. its on the list to try and make better (on top of what i have already introduced to try and make it better). i hear its worst on stock ICS.

you should most certainly not base the performance/operability of the tab on youtube HD performance. turn off all anims so it doesn't give you the 'illusion' of lag (since the anims operate a bit slow due to slow GPU/legacy HW). other HD video content (in an external player) should play fine (depending on how it was encoded, etc.).
[Galaxy Tab 10.1 Android Development] C-o-M:
AW: [ROM][P75xx][JB][4.2.2] CyanogenMod 10.1 Nightly Discussions

This means a wrong USB driver (on PC side?) can cause the Tab going crazy? I still don't get what the root cause of that "android_usb disable" bug was. I thought it was because of the new usb debugging security features. You said it should go away if the early start of usb debugging is disabled. Users say it isn't. (I still didn't have the tune to reproduce the issue at all)

Nevertheless, this was not an illusion of lag. It was not just "YouTube isn't smooth". It was "the CPU is at 100% at 1GHz all the time and video playback has gaps of 2 to 5 seconds".
[Galaxy Tab 10.1 Android Development] pershoot:
bad drivers can cause the tab to become unstable. it happens more frequently against the VZW model.

this is exactly why i said, one should not look at youtube HD as a benchmark to how the tab is operating. hitting a menu item and waiting 3 seconds, that's an issue or swiping and waiting for it to do something, that's an issue. looking at youtube hd and it pausing for a second or two, that's pretty much always happened (depending on the content and/or network speed (less so)). usually just micro stutters tho.

AW: [ROM][P75xx][JB][4.2.2] CyanogenMod 10.1 Nightly Discussions

Crazy. Another good reason not to use windows...

I accept your explanation, but I guess I will never understand it. Something like this should never happen. Because this means I could just connect the device once to a manipulated PC to make it unusable.

Normally I would totally agree with you. I never care about youtube performance issues. But this time the reason was the high cpu load and not network or content. I've seen the log files. Hopefully this is fixed now.
[Galaxy Tab 10.1 Android Development] pershoot:
In that particular instance, one may see it more readily via that specific app, but when the app experience is already sub par to an extent, its hard to make judgments based solely on that.

Not the app's fault by any means, just more work to accomplish to try and keep the legacy tab operating decently (where one day I dream of finishing up and moving on to bigger/greener and more modern pastures, hehe).
[Galaxy Tab 10.1 Android Development] kmaq:
i too was facing issue with USB driver all i did was (windows 7 32-bit):

- uninstalled kies & samsung usb driver

- reboot the pc

- installed samsung usb driver from xda thread

- reboot pc

after that so far i did not face issue related to MTP connectivity for SGS2 or GTab P7500.

may be some kies services causing these issues (not sure), give it a try.
