[Galaxy Note 10.1 General] JuniorGG:
Personally, I've noticed that the s-pen digitiser, when it is switched on, drains a considerable amount of energy. So do not expect extreme battery life if you use a lot the s-pen. Anyway, do check that the energy saving option under "Options - S Pen" is ticked. This way the digitiser will be off when the stylus is in its receptacle. This will save a good amount of battery when you're not using the pen (provided you insert it in its receptacle). Of course, this setting will have no effect whatsoever while you're using the pen.

In any case, a tablet like this is full of features and components that are potential battery killers, so how long the battery lasts, it's really up to how the owner uses it, and not only how much. For instance, I may be surfing the internet and checking emails all day long without using the pen, and consider it heavy use. How long will the battery last in such case? 15 hours? Ok.

Now, a seemingly opposite case could be this: I may have the tablet constantly standing by, but with the pen off its receptacle. Since I have never used the tablet, I have full right to swear that my usage of the tablet is extremely light. Well, only because I've left the pen out of its receptacle, my battery will run flat in just about 13 hours or so. And what's more confusing, is that if I go checking the battery stats, I will see no trace of the pen being the responsible for such a high drain, so I probably will end up getting the (wrong) idea that the battery life of this tablet is extremely poor.

Another case, among the many, is when the tablet tries to sync using the 3G connection, but gets no answer from the network because of problems of the mobile operator network (server not responding). This causes the 3G radio to remain constantly on and drain the battery very fast. Again, it is very difficult to understand the reason for such a quick discharge. Such an issue happens in certain areas of my city with Vodafone, for instance. When I go to that areas, I have to take care to switch off 3G data connection, or else my battery will be empty in a matter of a few hours.

IMHO the problem is, that android os is very incomplete when it comes to providing information for analysing power consumption, and this has always been the cause of big confusion and frustration.
[Galaxy Note 10.1 General] XenomorphXx121:
Ah think that was it thanks had the battery saving in pen unticked, wasn't sure whether to tick it or not.

I only have the wifi as got 3g on my phone so don't need it.

Main purpose bought it for was the pen but now have that ticked when not using it should make a difference :D
[Galaxy Note 10.1 General] asdfuogh:
Ah, I came from the original Asus Transformer, so I was a little nervous that this might not last long enough compared to the keyboard combo, but I haven't had a moment of "****! should have charged it!" in my daily usage so far (browsing reddit + drawing + taking notes).
[Galaxy Note 10.1 General] banderos101:
Im surprised no ones made a faq thread on sqeezing as much juice out of this thing, for newcomers, and oldcomers who may have missed one or two like

The aformentioned disable wacom when pen not in use

The obvious screen brightness level(would be nice to get an average indication on certain levels i.e. low, medium, high)

Disable/freeze/unistal unsused sometimes battery hogging stock apps

General global settings that compliment battery life

-i have an app called auto airplane, to make sure that as soon as the tablet goes to sleep, wifi turns off

-i generally only go above medium brightness rarely, and mostly stick anywhere between low and medium depending on how bright or dark the room is

-powersave surprisingly runs things pretty well, ive not had any slowdowns from any app

-bluetooth/gps off, unless needed

-i have sync on for xda/gmail instant notifications of posts, so syncing has always been a factor when i test my battery, result, sync no drain

Theres probably more out there, please feel free to post em
[Galaxy Note 10.1 General] chookmeister69:
I've had good battery life out of mine but can hardly call it phenomenal when comparing to other Tablets. Ipads are extremely good for that but I would never buy one. Basically if I game on it all day with portable hotspot running, bluetooth and downloading torrents it still easily lasts the day and that's all I can ask out of a tablet so I'm very happy with the battery life but I wouldn't rave about it compared to Tab 10.1 or ipad for example. It can do a whole lot more so for that I'll take the battery hit.
[Sony Xperia P, U, Sola, Go] xxrahulxx:
While trying to replace my stock lock screen with a custom one.

I deleted the UxpNxtLockScreen.apk file placed in the /system/app folder.

This should make my lock screen go away. But instead what happened is that now there is a new lock screen (see the attachment) instead of that.

Im confused as to how this is happening.

Anyone who has also experienced this?
[Sony Xperia P, U, Sola, Go] Me‎:
you removed sonys lockscreen and allowed stock ics lockscreen to show
[Sony Xperia P, U, Sola, Go] xxrahulxx:
Does it also mean that if I delete home.apk, I'll get the default ICS launcher?

Thanks for the info anyways :)
[Sony Xperia P, U, Sola, Go] Me‎:
I doubt it

but if you try make a nandroid backup first (and back hope.apk incase you can still use device)
[Sony Xperia P, U, Sola, Go] xxrahulxx:
I doubt if there is a way to take Nandroid backups on Sola.

So wont touch the home.apk

Thank you for answering my questions.

[Sony Xperia P, U, Sola, Go] Me‎:
i'll try on my U sometime and report back :)
[Sony Xperia P, U, Sola, Go] mirost1:
Dont do this, may you wont be able to use device.
[Sony Xperia P, U, Sola, Go] Me‎:
Did it just black screen

statusbar works recent apps work but can't get into any apps as far as I can see
[Sony Xperia P, U, Sola, Go] xxrahulxx:
Thanks brave soul.

You saved me from a big trouble.;)
[Sony Xperia P, U, Sola, Go] chewdaniel:
sony's lockscreen is an app. aosp lockscreen is in the framework. ALL launchers are apps. DO NOT REMOVE YOUR LAST LAUNCHER
[Sony Xperia P, U, Sola, Go] Me‎:
Yep it's not a very good idea lol

[T-Mobile, Samsung Galaxy SIII] leesanhua:
Hi there. Before update to JB on my S3, when i do my readings on the phone, screen blackout, press the HOME button, the screen will come back up.

Now, screen blackout, press HOME button, screen come back up but the app or browser that I'm using will close down instead of just led the screen on (where the app still there)

Anyone has a way to fix this? Keep pressing on the POWER button to light up the screen is not as Convenient as by using the HOME button.

Thank you.
[T-Mobile, Samsung Galaxy SIII] SportingChap:
Glad it's not just me. This has been driving me bonkers ever since I updated. It's really the only complaint I have about the official 4.1.1. ROM right now. Would love to hear some suggestions on how to fix. In the meantime, I've been trying to train myself to use the side power button for screen on action.
[T-Mobile, Samsung Galaxy SIII] leesanhua:
Is there anyway that we can make suggestions on this matter?

It bugs me when I read on the bed at night.
[T-Mobile, Samsung Galaxy SIII] cobraboy85:
this has been happening on jelly bean ROMs (not cm tho) ever since the leas came out - at least for me anyways. very irritating sometimes but yes, you are not the only one.
[T-Mobile, Samsung Galaxy SIII] SportingChap:
Bump. No one else is annoyed by this but us or has any idea for a fix? :eek:
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Only 'fix' is to use smart stay when theres enough light. Otherwise increase your screen on time to one min. I had to increase my time since I use it at night so often.
[T-Mobile, Samsung Galaxy SIII] Crisisx1:
An easy fix is just to use your power button as soon as the screen blacks out.

It wakes the screen back up without closing down the current app your in... I just tested it out and it works, doesn't lock the phone either.

But if you don't wanna use the power button then I suggest you increase your screen time out to one minute or more if you don't want the screen blacking out fast.
[T-Mobile, Samsung Galaxy SIII] demize!:
Very annoying and not something that can be considered useful in anyway, so a bug in my opinion.
[T-Mobile, Samsung Galaxy SIII] pytyper483:
Like someone else mentioned, what's wrong with smart stay?
[T-Mobile, Samsung Galaxy SIII] demize!:
Does it work in the dark when reading in bed like the OP asked? My comment was criticism of why they coded it this way,for what purpose?
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Its really just doing what its supposed to before the device locks. I guess they expected smart stay to take care of it.

If you keep double press home to open svoice enabled it should also stop this from happening.
[T-Mobile, Samsung Galaxy SIII] SportingChap:
Bingo. This is the answer. I'd much rather have the slight lag in returning to the home screen than lose the ability to turn the screen back on with the home key. Thanks!

delete please
[HTC One S] Perpetrator:
So I've noticed this strange bug ever since I've had the phone. Sometimes after turning the screen on, my screen won't register touch input properly - ill try to do my pattern unlock and it'll just jitter around and not work. After turning the screen off and on again its fixed. Anyone else have the same problem? It's happened on stock and every other rom I've used.
[HTC One S] Spastic909:
Sounds like a hardware issue.

Please post questions in the q&a section
[HTC One S] IVS IVRIS:
I have that too.. seems connected with the home screen bug / helicopetering..
[HTC One S] Perpetrator:
Never had the home screen bug happen even once on my device... Its a bit irritating but not that bad. It never happens after the screen has been on, only right when you turn it on
[HTC One S] IVS IVRIS:
Ah oke. We better pray for the jelly bean update then! Haha
[Sony Tablet S] SAJLD:
Well i have my tablet s the first one that cames with two games crash bandicoot and pinball but does those games are in the new xperia tablet s and if it doesnt how can i install those games in the new xperia tablet cause im selling the first one to buy the xperia one but i want those games and if there is a root for the xperia tablet
[Sony Tablet S] jumper62:
Try copying the apks from the original sony tablet s and copy them onto the xperia tablet s. Look in vendor/app
[Sony Tablet S] user298:
I did what the person above said and it worked.
[Sony Tablet S] Zer0K3wL:
Is their a download for it?

[Dell Venue] WhizKins:
Introduction

Hi guys!

I have successfully ported CM9 for our Dell Venue. Barring a few minor bugs and camera everything works fine :)

Credits

All people from Dell Streak Community (DSC especially kibuuka and _n0p_). Also, x1123 and all others who helped in testing my ROM :)

What Works

WiFi

Bluetooth

GSM

Sensors

Touch button lights

Hardware acceleration

Audio

...etc

What does not work

Camera

Few minor things

Not Tested

3G / 2G

GPS

NOTE: The power button and the headset do not work together for some reason. So, you have to choose one or the other. By default in my ROM the power button works but the headset does not. So, if you want the headset to work you will have to flash a separate kernel but then the power button will stop working.

So, it's highly recommended to turn on Volume Rocker Wake in Settings -> Display otherwise the screen won't turn on.

Downloads

Download Headset Fixhttp://www.mediafire.com/?wd1eewmip66a0xb
​

Instructions

Copy the ROM to your SD card

Reboot into recovery (Press Volume Up + Volume Down when starting the phone)

Select wipe data / factory reset

Flash the ROM and after that flash the headset fix if needed

Reboot and enjoy ;)

Feedback

I would appreciate your feedback on the ROM on this thread itself. For general ICS development (mainly for devs and testers) please visit this thread.

sir..congrats...thanks a lot for ur hard work...

Sir is der any chance of gettin miui v4???
[Dell Venue] streak4m3:
Thanks for the ROM. Can you add the gapps zip too?

Edit: These may be it: http://goo.im/gapps/gapps-ics-20120429-signed.zip
[Dell Venue] TheManii:
I've made a Gapps package for the S5/7/10 a while back, it should work on this.

(if you wish to comment on my package specifically, please do so in original thread)
[Dell Venue] changkho1908:
3G not auto dectect and can't add apn

camera not working :D

i wait MIUI V4 :D
[Dell Venue] chacona:
Thank you so much, it's a long time since we last tested a custom ROM! I will try it today! :)

Update: first impression is good: almost all things work well, except some minor points like you mentioned about the camera:

when turning on the Wifi, networks were not shown until I added one SSID manually myself;

MUTE key does not work;

Continue testing, and will update! :)
[Dell Venue] streak4m3:
I played with the ROM for a bit. Mobile data doesn't work for me (AT&T). There is a bit of stuttering in graphics but final image displays quickly enough. Touch feature is quite responsive. Pinch and zoom in browser lags quite a bit though. Of course, the OP already mentioned the camera and headset.

I'm impressed overall. It needs work but I believe things will get ironed out in no time :)
[Dell Venue] prasad12ka4:
How is the battery backup?

Also for camera Fix one can try as in below link:

[Dell Venue] GalaxyIV:
Thank you so much, i will test your rom :D
[Dell Venue] chacona:
Does not work, I flashed libcamera_update.v0.10. Did you?
[Dell Venue] TheManii:
Does the X10 even use the same camera module?

Sony designs their own camera modules, and may have used their own model in it, if that was the case there's no way it'd work. If it did work then something went horribly wrong.

There are working OV8810 drivers for other devices, the question is do they require kernel mods since the donor devices all used linux 3.0 and we dont.
[Dell Venue] kakagi:
Installed and tested the rom for 4 hours till now. Here is the list of my obserbations.

1. boot animation need resizing

2.wifi works but the color of the wifi doesnt change to blue it remains grey

above two is not an issue at all.

3. USSD code doesnt work. ===> fix: flash the ussd fix zip file for gingerbread rom posted by Themanii previously.

4.Mobile data doest work at all. some problem i guess. u can not create apn. i tried with tweakker application but strangely it says:

your sim card can not be used. make sure u have sim card and a proper gsm signal. you cannot use this application in airplane mode. but the phone already have the sim card and i can make call with it. see the attached screenshot (Baseband issue or rom issue ????)

5. There is no ringtone sound during incoming call. if u use the headset fix kernel u will get the sound via headset but not via phone speaker.

same applicable in case of any notification,

6.Wifi and usb tethering not working.( im sure it will work with 3rd party app from market)

7. And as the OP says headset and camera doesnt work. but if u flash the headset fix u can get the headset working but power button will stop functioning . so in case restart/shutdown use 3rd party application otherwise pull out your battery :P

8. Automatic brightness not working.

9. am/pm style not working under settings. it will not show anything either am or pm.

10. Led flashlight not working.

11. gallery>any photo>edit>face glow/ face tan produces force closes.

* @ Themanii i flashed your gapps but it doesnt include gtalk. and does google card not working for us??

This is my observation. i will post further if something unusual happen.

Everything else works for me thats includes wifi(need to add one ssid manually),usb mass storage, bt, incoming outgoing call, voice calirity, mute during call, gps, assisted gps, compass, auto rotation., touch, youtube in Hq also works but i get sign in error in youtube continiously dont know why.

so basically i found the above mention things is not working and rest of all cm9 feature is working.
[Dell Venue] kakagi:
this will not work for us.
[Dell Venue] x1123:
Great work Whizkins .... You are the Man at least dell venue will keep going. I flashed and feel better than NexusOne DV is best among qsd8k board phone ... for camera there is open source drivers but work not so good I think :D ...
[Dell Venue] lungocphu:
Dear friends,

I flashed this ROM on my DV, but I don't know why it not SOUND when receive call

- Ringtone NOT work

- Notification work well

- Alarm work

I heard someone Ringtone work well, please guide how to set up it
[Dell Venue] kakagi:
yes no sound in ringtone. U can use vibration instead.
[Dell Venue] x1123:
flash with attached kernel with CWM ringtone will ringing ..... :D
[Dell Venue] x1123:
RINGING ROM DOWNLOAD

[Dell Venue] terminal17:
I am using this app called extended power menu...it has a screen off mode...but u need the phone to be rooted...it is available on play store...otherwise chk this forum
[Dell Venue] GRider02:
thank you.

but can't we port the soft keys to cm.

they look perfect.
[Dell Venue] kibuuka:
WiFi icon

Just as planned :)

wpa_supplicant version 0.8.x makes rssi (wifi signal strenght) to be interpreted and displayed correctly.

View attachment wpa_supplicant.zip adb push it to /system/bin (don't forget to set permissions to 0755)
[Dell Venue] kakagi:
thanx working perfect :)
[Dell Venue] Rameshkrish:
charge drops down very fast and phone gets heated up while charging higher.

any ways to solve this?

i use 3g in my phone.brightness 0 level
[Dell Venue] kibuuka:
I think you're posting in wrong forum. Post it in Q&A (don't forget to provide additional details because general tip for "sounds from the underground" type of questions is "do a factory reset". Didn't meant to sound rough.).
[Dell Venue] terminal17:
How to set permissions?
[Dell Venue] kibuuka:
adb shell chmod 0755 /system/bin/wpa_supplicant
[Dell Venue] kibuuka:
New observations.

1. Mute key is functional in terms of it's keycode being readeable and reporteable by system. View attachment mutekey.kl.zip is a keylayout file demoing it (in a buggy way, though). Problem is that (according of mutekey.kl found in stock rom) in froyo and gb dell used non-standard keycode/framework modification (RINGER_MUTE) to deal with physical mute key presence. In stock android there's NO RINGER_MUTE keycode, instead it includes MANNERS_MODE (which, judging by api description, is "Key code constant: Manner Mode key. Toggles silent or vibrate mode on and off to make the device behave more politely in certain settings such as on a crowded train. On some devices, the key may only operate when long-pressed."). Sounds like that's exactly what we need. Now bad news - there's NO handler for it in standard system_server, neither in aosp nor custom source tree like cm, so MANNERS_MODE currently does nothing. When substituting VOLUME_MUTE (like it's done in attached file) makes device to try to mute, but there's a conflict between system_server and android.systemui - sort of racing condition - you need to adb push to see it yourself, it's sort of fun. :) When substituting MUTE - result makes you able to (surprise!) mute a microphone using mute key while on call.

To install keylayout:

adb push mutekey.kl /system/usr/keylayout/
adb shell chmod 644 /system/key/layout/mutekey.kl
adb reboot

2. There seems to be an error/incompleteness in device overlay - we have working ambient light sensor (checked using elixir2 - it showed lighting conditions changes) and no way to toggle it in settings pane. Looks like <bool name="config_automatic_brightness_available">true</bool> from device overlay failed to get into settinge beins included into ota or somehow is being ignored by system. No Idea why as of now.
[Dell Venue] x1123:
Good news. Kiibuka back to forum. I will rebuild. Cm9 with most cm flavour. Previous built is more AOSP than cm. With help of kibuuka. I thing we can build better before migrate to JB. I finished resync cm9 source. I will build again and upload system.img and boot.img for testing since my dv in trouble with battery. I can upload tonight.

sent by Tapatalk on Android Device
[Dell Venue] kibuuka:
If you're about to rebuild i would suggest two above-mentioned changes: wpa_supplicant and froyo's RIL. Also, about bootanimation - try to change 800x480 in config to just 480 (haven't tried this one myself, found this change while messing with configs for htc pyramid - it has 960x540 resolution and bootanimation setting was set to 540, not 960x540)

Oh, and what exactly has been done with power button that it's became unfunctional?
[Dell Venue] x1123:
Kibuuka

Can u give me the details. What should be modified for wpa_supplicant. I think for eye candy like bootanimation we can do it later.

sent by Tapatalk on Android Device
[Dell Venue] kibuuka:
Nothing really hard :) just change version to be built from 0_5_X to 0_6_X in BoardConfig.mk, should do the trick.

Bootanimation change is just as simple. Remove 800x leaving just 480 in corresponding .mk (can't recall it' name, away from build pc)
[Dell Venue] x1123:
But my build is against 0_8_x in BoardConfig since at that time 0_5_x is NOT BUILD for dell venue
[Dell Venue] kibuuka:
Bah, 0.8., not 0.6 of course. My bad. And about your build, do you have it installed right now? Do adb shell wpa_supplicant -v. Which version it has?

I'm asking this because whiz's build with your kernel (that was the thing i was playing with) has 0.5.1x after clean install. Looks like it's not beind actually built but dropped in from vendor blobs.
[Dell Venue] x1123:
:D my device is sleeping all time. No Battery. I need to do a surgery to battery and replace the battery component. I need 48 minutes to build and will upload somewhere. But we must wait someone willing to test .... LOL .. I have everything battery related in hand and have time to do surgery. I think next one hour my DV will lights up :D
[Dell Venue] kibuuka:
Heh, good luck. Meanwhile do a check of vendor blobs related makefiles and remove/comnent lines having wpa_supplicant in them if you find them.

About being a test subject - i will do this job (if manage to take wife's dv away :D)
