Re: [ROM][4.2.1] My Android 4.2 for Xoom Wi-Fi - Stable Release (20130127)

Strange GPS behavior. Turned on for a few minutes to test lock time, then turned off. Battery history shows GPS continually on and using battery resources. Even went into location settings to see if the quick song didn't turn it off, but the box was not checked. Did another toggle and still no luck turning it off.
[Xoom Android Development] dreamcwli:
I think previous kernel may be the reason of your Photo Sphere camera but it is fine to try it. I will upload kernel with overclocked GPU frequency later.

Can you try other apps using GPS to see if them work even GPS is turned off? I have tested it with Google Maps but seem fine so far.
[Xoom Android Development] Winesnob:
Re: [ROM][4.2.1] My Android 4.2 for Xoom Wi-Fi - Stable Release (20130127)

I used GPS test, and GPS registers as off when it is off. Still shows the blue indicator in battery that GPS is on. Odd thing from before is that I only had Maps and GPS on for a few minutes, but the battery stats are showing more than 26 minutes of GPS time.
[Xoom Android Development] dreamcwli:
Does reboot help? Sounds weird and I have no idea about that...
[Xoom Android Development] arielp:
fortunately i dont have that GPS issue, GPS locks in 4-5s, and stay off if quit the app.
[Xoom Android Development] Winesnob:
Re: [ROM][4.2.1] My Android 4.2 for Xoom Wi-Fi - Stable Release (20130127)

Reboot makes the indicator in battery disappear. At this point I'm not even sure that battery is actually being used, but the GPS on time is being recorded as if it is.

GPS does lock stupid fast when it's on, so no issues there. Just deceptive battery stats.
[Xoom Android Development] dreamcwli:
Maybe there are some small bugs in battery history so it doesn't show correctly. If you have strange battery consumption please let me know.
[Xoom Android Development] GuiPoM:
One hard reset occurred during night :(

http://pastebin.com/i3z4337m

But when my xoom is used (game or youtube) it is very stable ...
[Xoom Android Development] dreamcwli:
Do you have SD card in your Xoom? Looks like there are some problems with SD card.
[Xoom Android Development] guitmz:
ROM looks good here so far :)

Quick question.. Is there a patch to get back the UI of 4.1.2? I mean the navbar on the bottom right instead of the center, etc

Thanks

Re: [ROM][4.2.1] My Android 4.2 for Xoom Wi-Fi - Stable Release (20130127)

Its on setting -> interface -> use system bar

---------- Post added at 11:58 AM ---------- Previous post was at 11:53 AM ----------

Maybe not specific this rom,

I notice on xoom with tegra 2 and my droid x2 which use the same tegra.

Why on some 3d games, such as Trail Extreme, and some other titles, bumb mapping seems not enabled on xoom.

So the texture seems flat as opposed when bump map enabled like on droid x2. The texture become good, overall 3d image improved.

Onject reflection (specular light) also missing, made object kinda dull

Is it driver issue or what, any idea?

I will post comparison sccreenshot soom
[Xoom Android Development] GuiPoM:
Yes. I will remove it and try again. Thanks !

What kind of problem ? File corruption ?

Because to my understanding this was more related to tegra frequence management or memory management. But I'm not used to read kernel dumps.
[Xoom Android Development] dreamcwli:
I think you can test it with stock Android 4.1.2 to check the problem. There are too many differences between your Xoom and Droid X2 now so we should at least test it on the stock ROM.

I see some error messages about the reboot with I/O on storage. I don't actually know what is the problem but I think it is fine to start from removing the SD card to check it.
[Xoom Android Development] arielp:
Re: [ROM][4.2.1] My Android 4.2 for Xoom Wi-Fi - Stable Release (20130127)

Nah.. Still the same. Stock, eos, this, the same,

No its not about this rom in particular, seems on all rom (never try on HC though)
[Xoom Android Development] dreamcwli:
Maybe developers dropped some effects to improve the performance on tablets.
[Xoom Android Development] egrus:
I apologize if this is off topic. First of all I'd like to thank the developer and all that contribute with their input, this is by far my favorite ROM. I used to own an Acer A500 and on custom JB ROMs I noticed that the audio latency was low. I used a music making program called "Caustic" and on the Acer the latency was lower than 50ms whereas in this Xoom ROM, it's 93ms. I sold the Acer because of its microphone issues and inferior speaker audio, I am much happier with the Xoom! I have searched for answers regarding the larger audio latency on the Xoom, after I heard that on JB 4.2 the latency was much improved. I can not find any answers to my question, and don't know what part of the ROM this issue is related to. I am pretty technical with Android but don't know a lot about the variables that make certain things work better, e.g. the audio. Btw, I flashed EOS4 previously and the latency went up to a whopping 293ms. Any help would be greatly appreciated, again, I am sorry if this is off topic!
[Xoom Android Development] GuiPoM:
I am running my device without SD card. I rebooted just in case the sd card was not properly unmounted.

Almost 2 minutes after, my xoom went through an hard reset.

http://pastebin.com/uHG28t8H

What I notice is that the device reboot only when it is in sleep mode or going into sleep mode. Not when it is alive.

Hope you will have some ideas where the problem could be located.

I will keep the rom to make some tests then revert to stock rom to get back a stable OS.
[Xoom Android Development] grey.ghost:
Re: [ROM][4.2.1] My Android 4.2 for Xoom Wi-Fi - Stable Release (20130127)

Are there user controls for the quick settins panel? I.E. Adding or removing buttons. I'd like to add a volume button, and remove the user button. I've been through the settings but haven't been able to find any are where this can be customized. May not be possible...just asking.

Thanks - gg
[Xoom Android Development] kinder771:
Have to say that the release is really excellent, didn't notice any bug !

How do you unmount a usb drive ?
[Xoom Android Development] dreamcwli:
Re: [ROM][4.2.1] My Android 4.2 for Xoom Wi-Fi - Stable Release (20130127)

I will test it on other devices with Android 4.2 to see if it is common problem. Does CPU overclocking make it better?

EDIT:

After checking the introduction for Android 4.2 I think low-latency playback is a feature required hardware support. I don't know if Xoom is capable of the feature but I will check it later.

Looks like the same problem. I will build a stock kernel with only required changes for Android 4.2 to see if it helps.

Have not implemented it yet so not possible in current version.

You have to go to settings => storage => unmount USB storage.
[Xoom Android Development] kckingc:
Re: [ROM][4.2.1] My Android 4.2 for Xoom Wi-Fi - Stable Release (20130127)

Best release, yet! Thank you.

One small issue I noticed is that my Xoom's lock screen won't unlock with the pattern when it is plugged into power and is fully charged. It is just unresponsive to the pattern I draw. Then, when I disconnect the power, it immediately starts responding.... Very strange and certainly not worth spending much time looking into, but I did want to mention it in case there are other related symptoms.

Thank you very much again for keeping my Xoom in supply of a good new OS!
[Xoom Android Development] dreamcwli:
I will check the problem, thanks for reporting!

I see low-latency playback requires hardware support here. Although Acer A500 is a Tegra 2 device it may have different sound chip with Xoom that make the difference. I will check it but if it is something related to proprietary drivers I can't do anything to improve it.
[Xoom Android Development] GuiPoM:
Ok. You can contact me when you will have time to build it and I will test and report. Thanks!
[Xoom Android Development] dreamcwli:
I have tried it last night but works fine. I think I had this problem in the early stage of this ROM but it seem resolved to me for a while. I can't remember what I have done but maybe you can test this problem with clean system?

Does anyone have the same problem?
[Xoom Android Development] AlEsC:
Re: [ROM][4.2.1] My Android 4.2 for Xoom Wi-Fi - Stable Release (20130127)

One thing that used to work on this rom but does not work anymore is the ability for application to ask fer complete fullscreen (hide soft buttons + taskbar), eg while playing a video with DicePlayer.

Again, it used to work, I think (but absolutly not sure) it stoped working when the swith for phoneui/tabletui didn't require a reboot anymore.
[Xoom Android Development] dreamcwli:
Re: [ROM][4.2.1] My Android 4.2 for Xoom Wi-Fi - Stable Release (20130127)

I will check it. Does the problem remain after rebooting?
[Xoom Android Development] AlEsC:
Re: [ROM][4.2.1] My Android 4.2 for Xoom Wi-Fi - Stable Release (20130127)

No it does not.

Would be cool to have this possibility in tablet ui, or something like on EOS3 a power menu to toggle bar visibility.
[Xoom Android Development] dreamcwli:
I think I have found the problem. If you booted with phone UI the fullscreen feature will be functional. I will try to fix it in next release and thanks for your reporting.

Hiding navigation bar is a nice feature but it may be confusing for some users. Since it can be achieved by some apps I have no plan to implement at the moment.
[Xoom Android Development] guitmz:
really nice rom!
[Xoom Android Development] kckingc:
Re: [ROM][4.2.1] My Android 4.2 for Xoom Wi-Fi - Stable Release (20130127)

Tested it in detail again today. Everything works fine right up until the charging light turns green. At that point the pulsing message light continues pulsing when I wake up the screen via the power button, and the screen won't react to the pattern I draw. Then, when I pull the power connector, it immediately starts working. Again, not a big deal, but strange.
[Xoom Android Development] mohamed_moscow:
i have no problem like that on my xoom wifi ( build 27.01) and no problem with the screen while charging
[Xoom Android Development] Winesnob:
Re: [ROM][4.2.1] My Android 4.2 for Xoom Wi-Fi - Stable Release (20130127)

I think there may be an issue/bug related to the interactive cpu governor. Still having app freezes in Angry Birds, so started playing with settings. No issue with other governors, so moved back to on-demand and over clocking to 1.5 without issues.
[Xoom Android Development] dreamcwli:
How long have you played to get the app freeze and which version is it? I want to test it for getting some logs.
[Xoom Android Development] Winesnob:
Re: [ROM][4.2.1] My Android 4.2 for Xoom Wi-Fi - Stable Release (20130127)

Usually only takes a few minutes of play to get the result. Angry Birds Space premium, most current version of stable ROM.
[Xoom Android Development] crisisinthecity:
Re: [ROM][4.2.1] My Android 4.2 for Xoom Wi-Fi - Stable Release (20130127)

I'm on a the newest version. It was perfect until I tried to go into developer options and overclock. I changed to 1.5 and got a few freezes and reboots. Changed it back to the default settings and rebooted and haven't had a lock up since. Tried on demand scaling and it was lagging. Great ROM!
[Xoom Android Development] PearlMikeJam:
Re: [ROM][4.2.1] My Android 4.2 for Xoom Wi-Fi - Stable Release (20130127)

Mine froze when my son was playing Angry Birds Space too (free version) after about 5 minutes. We were able to use the home button and get to other apps, but AB Space would not respond. Seems to be specific to that app because Angry Birds Star Wars worked fine for quite a while.
[Xoom Android Development] Winesnob:
Re: [ROM][4.2.1] My Android 4.2 for Xoom Wi-Fi - Stable Release (20130127)

Solved this issue by changing cpu governor to ondemand. Some say it causes lag, but I'm overclocked to 1.5 GHz and really don't notice.
[Xoom Android Development] dreamcwli:
Re: [ROM][4.2.1] My Android 4.2 for Xoom Wi-Fi - Stable Release (20130127)

I think overclocking doesn't work on every Xoom and maybe you can try to use lower CPU frequency like 1.2 or 1.4 GHz to see how it works.

Got the same result here. I will try to see what I can do for this problem.
[Xoom Android Development] PearlMikeJam:
Re: [ROM][4.2.1] My Android 4.2 for Xoom Wi-Fi - Stable Release (20130127)

For what it is worth, I have not tweaked anything. I am running your stock ROM with tablet UI.
[Xoom Android Development] sabbathmaniac:
Thank you dreamcwli for this ROM i've DL and flashed it yesterday and since then i haven't seen any bugs other than mentioned in your post.

fast and smooth and i love it, but i do have a question for XOOM owners:

IF Motorola says they stopped supporting Xoom wifi and now we have the 4.2.1 thanks to you, will there be Roms or moded stocks served in future of the fellas Xoom owners ?

The device is old but still its damn good piece of tech and its very sad seeing others enjoying the new releases while Xoom Wifi still behind.
[Xoom Android Development] Winesnob:
Re: [ROM][4.2.1] My Android 4.2 for Xoom Wi-Fi - Stable Release (20130127)

[Xoom Android Development] AlEsC:
Re: [ROM][4.2.1] My Android 4.2 for Xoom Wi-Fi - Stable Release (20130127)

Maybe out of topic but is there a hardware reason we do not have wifi-direct on Xoom or is this because of the wifi driver ?
[Xoom Android Development] dreamcwli:
The Wi-Fi driver. I have seen Broadcom demonstrate Wi-Fi Direct with Xoom but the proprietary binary isn't available for customers. I tried to ask Broadcom for it but had no luck.
[Xoom Android Development] alex94kumar:
Hey Dream, any chance you'll ever add the CRT off-animation to the rom? It's on eos 4, and i was just curious if you'd ever add it to MyAndroid. It's a cool thing to show off to iphone and ipad users ;)
[Xoom Android Development] dreamcwli:
I will try to see how it works.
[Xoom Android Development] alex94kumar:
Sweet! If you want, you could send me a test version of the rom if you dont want to release it to everyone just yet
[Xoom Android Development] tumpy:
In my opinion I think you should leave the ROM as is, both team oes and cm are good coders but they Xoom ROMs cannot compare with yours both lag real bad, stick with your motto pure and simple, adding what all are requesting will make the ROM act like cm and eos laggy..
[Xoom Android Development] sabbathmaniac:
Re: [ROM][4.2.1] My Android 4.2 for Xoom Wi-Fi - Stable Release (20130127)

I'm 1000% with trumpy
[Xoom Android Development] alex94kumar:
CRT animation isn't some system consuming feature lol its one of those cool things exclusive to android, and looks awesome on a tablet. Its not like he's changing the entire design of the rom
[Xoom Android Development] sammyroot:
I have to admit, I jut picked up a used xoom about a month ago. Flashed EOS and CM10.1 etc, but didn't like the nexus 7 look, i guess people call it phablet. I went back to rooted stock, but missed some customization.

Just tried your rom and so far its great!! Its exactly what I'm looking for. Just a couple quick questions. Besides for putting this on "tablet ui" mode (which is awesome!) is there any way of gettign the stock 4.1 look of the Google search and app drawer, upper left and upper right of screen. Just curious. Great job!

Joey
[Xoom Android Development] dreamcwli:
Re: [ROM][4.2.1] My Android 4.2 for Xoom Wi-Fi - Stable Release (20130127)

That is the reason why I said I will try it instead of I will add it. If it doesn't feel good I will not add it in the ROM.

I have tried it but I think it doesn't work well on Xoom. Truely it doesn't affect the system performance but it is a bit laggy when turnning off the screen. I prefer not to add it if I can't find a way to make it better. If you like it you can use apktool to add it as described here.

Currently there is no way to change it unless you use another launcher forked from the launcher used before Android 4.2. I would like to bring it back but I am busy now and have not much time to work on it. You can try Apex Launcher and Nova Launcher to see if they work for you.

[Xoom Android Development] dreamcwli:
Re: [ROM][4.2.1] My Android 4.2 for Xoom Wi-Fi - Stable Release (20130127)

Xoom has 5 MP rear camera from the spec.

[Xoom Android Development] notbrodie:
I tried searching but got no results: can this rom hide the nav bar, but keep the phablet ui?
[Xoom Android Development] BorgCymru:
Great ROM, working good on my Xoom

Is there any way to get the 9 dot App draw shortcut in the lower centre of the screen back though and move the return/home/used apps buttons to the side

Also, although it may not be needed, why can't I move any of my apps to SD card ?

Thanks ( Not that 'jargon' savy so be kind.
[Xoom Android Development] Lothaen:
Re: [ROM][4.2.1] My Android 4.2 for Xoom Wi-Fi - Stable Release (20130127)

For some reason I always thought it was 8 :P

It always seemed better than my Desire and Evo till I got my Nexus4 anyway.

Thanks guys.
[Xoom Android Development] russtyd:
Hi @dreamcwli great ROM, but one request,can a file manager be installed as part of the base package (something like OI File Manager)? It would be really helpful if you could include one.

Having quickly tried this (having been exclusively on EOS roms since getting my Xoom a year ago) its very smooth :)
[Xoom Android Development] tumpy:
Settings -user interface -user system bar...
[Xoom Android Development] BorgCymru:

I've seen elsewhere that you can switch between phone and table UI . Is that in the same place?

Re: [ROM][4.2.1] My Android 4.2 for Xoom Wi-Fi - Stable Release (20130127)

[Xoom Android Development] BorgCymru:
I use ADW launcher because I hate the way all the 'apps shortcuts' are bundled together so I have sections for them by type in a tab system.

Can I also do this with apex ?

Dream, any idea about a Stingray version? I really like your work but need to use data on mine.
[Xoom Android Development] dreamcwli:
No, but I think there should be some apps can do it.

I think the app drawer is on top right before Android 4.2?

Since everyone has his own choice on file manager so I prefer not to add it. I have once considered to add CM File Manager but found it is still not good enough to meet most usage. I think we can have several flashable packages for people who need a built-in file manager.

I have been busy for a while and have not much time for working on it. I will make an experimental build next week so please help me to test it at the time.
[Xoom Android Development] russtyd:
OK, no problem - I created my own flashable zip using the Aroma App Package Creator.... don't know why I didn't think of that before :)

[Xoom Android Development] PearlMikeJam:
Has anyone been able to play Where's My Valentine by Disney? My son downloaded it yesterday. It opens, but then freezes halfway through the opening. The app continues to play it theme music, but the Xoom is unresponsive to any touch. A Power + Volume Up reboot is the only way to get things functional again. I believe we have a similar issue with Where's My Perry by Disney. If either work for you, what are your settings? I am running stock and have not tweaked the clock speed or the governor.
[Xoom Android Development] Winesnob:
Re: [ROM][4.2.1] My Android 4.2 for Xoom Wi-Fi - Stable Release (20130127)

Shot in the dark since I haven't tried either of these apps, change the CPU governor to on-demand. This solved freeze ups with the angry birds series.
[Xoom Android Development] PearlMikeJam:
Re: [ROM][4.2.1] My Android 4.2 for Xoom Wi-Fi - Stable Release (20130127)

Good suggestion. I gave it a try after a reboot, but same result. I will keep the on demand governor since the kids like Angry Birds.

Where's my Valentine is Working over here. I did get the launcher to force close one by try to click on both presents at the same time.

Dev settings> force gpu rendering is checked

Max 1500 mhz interactive governor.

This game is actually 2 apps wrapped in a kludgy holiday ad wrapper. Uninstall Valentine and load them separately

*Where's my Perry

[Xoom Android Development] PearlMikeJam:
Your setting worked for My Valentine. I have not tried it with Where's Perry. Strange part is Where's My Water works with the stock settings. I may experiment to see if lower clock speeds work. The clock speed is necessary. Just forcing GPU did not work on stock settings.

Thanks for the help.
[Xoom Android Development] dreamcwli:
I am trying to solve the problem but still no progress yet. I think there may be something wrong in the graphic system since the problem seem to happen in games. Has anyone tried another ROM and got the same problem?

Yes, after the source code of 4.2.2 released I will merge them.
[Xoom Android Development] mohamed_moscow:
i tried this kernel and all the games played good (http://www.mediafire.com/?p0hw9u8aggq6rev)
[Xoom Android Development] lepa71:
Where did you get this kernel? It looks like EOS3(which is 4.1.x)?
[Xoom Android Development] dreamcwli:
Don't use kernel not built for Android 4.2 or you will get random reboots. I think EOS kernel use another governor as default so it should be fine if changing governor can solve the problem.
[Xoom Android Development] mohamed_moscow:
i tried it without over clocking and changing governor and i didn`t have any reboot. it is for android 4.1.2. but it works not bad.

maybe you should look on the gpu oc.

And with you kernel i got faster working when i decrease the frequency to 912. But i don`t know why is that.
[Xoom Android Development] dreamcwli:
You can keep it running for some time and I think you will get random reboots.

In fact I just reverted GPU overclocking in last build to reduce instability and battery usage. To make the ROM stable for more users I have to avoid some tweaks. Maybe you can ask other kernel developers on this forum to build kernels with GPU overclocking?
