charging issue with 3.56?

My i815 tablet froze at 13% (my dumbass fault) and I went to reboot and it gets stuck on the Samsung logo. I thought no big deal so I tried to boot into TWRP recovery. The recovery title pops up for about a second and goes to black and then stops at the Samsung logo again. So I thought maybe not enough power to boot into either the system or recovery so I plugged in the tablet. The stock battery icon comes up for about a second and switches over to the PA charging icon, will go from empty to full less then twice, goes black and repeats the process. I've had the tablet plugged in for about an hour and the charging icon now starts at a 1/4 and same icon pattern keeps repeating and I still cant get into recovery or boot the tablet.

Does PA have an issue charging from dead, or a problem charging while turned off? I appreciate any and all help.

And also let me know if this sounds like a PA problem or a tablet problem, if something else i'll move on

Update: I was able to convert twrp from .img to .tar.md5 using my linux desktop and flashed it using Odin. Still wasn't able to get into recovery so I'm not sure if it made a difference but I let it sit at the Samsung logo for about 30 min and it finally booted up. No idea what happened but glad to have my tablet back.

I'm doing quite well with wifi on the 26 May ROM, so it's not necessary to flash latest kernel?

Thanks

[Galaxy Tab 7.7 Android Development] daniel_hk:
Don't know what frozen at 13% means but your partition table is probably corrupted.

Rom and recovery are in different partitions. They are not related. Normally, you'll never touch the /recovery partition (it is not even mounted).

The only possibility is invalid PIT info. Usually caused by incomplete flash or force reset during boot (at the moment when partition table update haven't finished).

You may flash the recovery with the PIT file included in Odin. Hopefully, you should have all your data in internal sd preserved. You probably need a clean reflash of rom follow.

Good luck!
[Galaxy Tab 7.7 Android Development] daniel_hk:
I don't know if it's your case.

The cpu is capable of idling at sleep now. In some situation, both cores may be in idle state. It may requires a second or two to wakeup. Even no. of pwr button press may turn off the screen again, even when cpu awake. Interrupt issue by other events (vol button) can turn on the screen too.

I installed the WiFi A rev. Found the hotspot in settings but upon turning ON, it will crashed the WiFi and stop working. Had to restart to make it work...
[Galaxy Tab 7.7 Android Development] Nuclear Blast:
Daniel, issue of battery drain have been fixed by you, MAN!

59%--->56% in night idle|stand by mode (near 7h) with Wi-Fi and Mobile data on, GPS offcourse off.

Theese results - with new kerenel-A version.

I continue to monitor further!

Thanx, Man!

WiFi heating drain

Just got the WiFi heating drain last night with Kernel cm-10.1-p6800_kernel-a-20130602.zip. WiFi was left turned on, in range of a the home WiFi network (so should have remained connected all the time, not searching). In the morning, the tab was warm to the touch, and had shut itself down. After booting it (just needed long-press power button as normal) I found that the battery reported 54% charge, but the battery stats showed a more normal usage curve and about 95% charge (see screenshot), so something weird is going on.

I'm going to try the cm-10.1-p6800_kernel-s-20130602.zip kernel next and see if I get any different results
[Galaxy Tab 7.7 Android Development] Espen96:
I think the priority is to get rid of the more serious issues first. But if you are reffering to screen tearing that would be a vsync issue.
[Galaxy Tab 7.7 Android Development] daniel_hk:
There is no major differences in power management between the two drivers.

I'm on battery for 2d10h now and I still have 10%.

I just want to clarify.

1. Are you in the 0601 cm10.1, or PA3.56?

2. Did you wipe data when flashing the previous rom?

3. Did you change the voltage table of CPU?

Thanks!
[Galaxy Tab 7.7 Android Development] Nuclear Blast:
Hm-mmm...are you shure that you have A-kerenel from 02 of june+3.56PA?
[Galaxy Tab 7.7 Android Development] AlexVallat:
Sorry for the lack of details! I was on pa_p6800-3.56-25MAY2013-231742.zip, and since installing that, I hadn't experienced the drain/heat bug for several days. When I installed it I wiped caches, but not data. Previously, I'd have been on pa_p6800-3.50-09MAY2013-003246.zip, and had experienced the bug at least once or twice, and I think with the version prior to that too. It isn't something that can be reliably reproduced, it doesn't happen every night, and I can't see any obvious differences between when it does and doesn't occur.

Two nights ago, I noticed the drain/heat bug again, so when I saw your kernels with experimental WiFi changes I thought it was worth a try, so I installed the -a version.

I haven't changed the voltage table of the CPU.

To be absolutely clear, this isn't a continuous problem where WiFi uses too much power, in normal use it uses an appropriate amount of power and doesn't get hot. I get similar results to you where it lasts days on a single charge. This is an intermittent issue that is triggered by causes unknown, but I've only encountered it when WiFi is turned on, and the device is turned off (sleep, not powered-off) for a long-ish time (hours, not minutes). When it is triggered, something causes the tablet to get hot and drain battery quickly, then power itself down, usually but not always before the battery is completely drained. Perhaps it's a safety power-down or something, I don't know.

I was just about to come here and report positive results.

On the 26 May 3.56 version, I did not get the battery drain bug but still battery usage wasn't what I'd expect.

On the 2 June kernel, it's more what I remember from ICS -- after 20 hours on the new kernel, I'm at 52%. This includes a nice mix of heavy and moderate use, as well as some long sleep time.

I'll keep monitoring usage during sleep time to see if I experience what Alex noted, but so far so good on my i815.
[Galaxy Tab 7.7 Android Development] Kholargol:
Just to say that I finally installed this ROM and that I'm happy with it. No force close or whatever. There are some little drawback but they are minors. Many thanks !
[Galaxy Tab 7.7 Android Development] niceashwin79:
Thanks Daniel!!!

It is working for my P6800. Initial operations are seems ok just there were few apps not working like gmail, facebook etc.

Also firefox and chrome suddenly closes without any warning and error.

Can you please guide me for way out!!!

Thanks...This new look is awesome and I am loving it.Wifi and data also seems ok so far in couple of hours.

[Galaxy Tab 7.7 Android Development] ColBill:
No WIFI drops

WIFI and battery are working well. Have a question. For this kernel are you using the pegasusq governor (you discussed in post 332) or some other one and which io schedulers in the latest kernel? I was thinking of applying some adjustments using PMR. Excellent work :good:and thanks again.
[Galaxy Tab 7.7 Android Development] paranoiadk:
Firefox sometimes unexpectedly quits on me too. It does pull up the error report screen but not always. Free RAM issue perhaps?

[MENTION=4948627]daniel_hk[/MENTION]:

I have a request. I did something very stupid and now only 1/3 of my screen is active. :D

I tried to replace the boot animation and did so with success, but the orientation was all wrong. So I rotated the jpegs inside the zip and put it back in place. Still nothing. After that I flipped the resolution numbers in desc.txt. Here's where it all went wrong. Basically, after boot I have landscape going on in portrait, while the app orientation stays portrait. It was a stoopid idea...

Could you please, pretty please make me a CWM flashable bootanimation zip (stock PA or just anything you have at hand)? Pretty please:fingers-crossed:

I've been trying to make it myself but CWM refused, then got stuck on status 7 and then on status 6... I know I could just reflash the rom, but I would lose many settings that I just can't save now.
[Galaxy Tab 7.7 Android Development] pemmoura:
Hi,

does this rom have graphical glitches like cm10.1?

When sliding down the notification menu and other animations (mainly with transparency on CM10.1) the screen have some glitches.

Thanks.
[Galaxy Tab 7.7 Android Development] daniel_hk:
Wrong bootanimation may corrupt the dalvik cache just like what we had in pa2.50 but I don't know why the orientation of the rom may be affected. :confused:

Bootanimation is in the /system/media folder. You better use adb to delete the one inside your tab first. Do a wipe caches. If everything back to normal, you may copy the file in the same location insdie the rom .zip directly.

If you don't know how to use adb, I have no problem to spare a few minute to make you a zip. To be safe, however, I suggest you flash the rom+gapps again. Then wipe cache and dalvik cache. Alll apps and widget will be preserved. This will ensure no other hidden bugs may have...

PM me if you still want the bootanimation zip. ;)

Good luck!
[Galaxy Tab 7.7 Android Development] KLASH1984:
my P6800 still overheat after install ver. 3.56 >.<
[Galaxy Tab 7.7 Android Development] daniel_hk:
If you haven't do a factory reset, you better redo it. No need to reflash the rom+gapps. Just factory reset and reboot. You will be prompted to setup again.

If already done, which gapps you flashed?

The pa_gapps (latest is 0524) I included in the post should work fine.

Good luck!
[Galaxy Tab 7.7 Android Development] daniel_hk:
The default GOV is ondemand and io scheduleer is cfq. You can change them with apps like Pimp my Rom, System tuner or SetCPU ..etc.

Good luck! ;)
[Galaxy Tab 7.7 Android Development] daniel_hk:
You need the new kernel (2Jun) too...

Good luck!
[Galaxy Tab 7.7 Android Development] paranoiadk:
Well this is embarassing. :o Completely forgot about adb. I tried terminal (blind, as I can only see the keyboard) but didn't do much.

I'll try it this way, and if it won't work, I'll reflash.

Thanks.

I'm posting a pic or two just to show what had happened

EDIT: Turns out I don't have adb on my computer anymore (must have reformated since last using it) and at this point it's easier and faster to just reflash.
[Galaxy Tab 7.7 Android Development] daniel_hk:
Got it, just tuncation of the upper part. Make sense, over size boot animation can cause that. Delete it will be OK.

Good luck!
[Galaxy Tab 7.7 Android Development] paranoiadk:
I've reflashed and lost my launcher settings (I had converted it to a system app, although I guess in JB it's not really necessary anymore).

Luckily I had a backup from not long ago. Up and running as it should be. :)

This time I'll ask before jumping into deep water: How can I change the boot animation and flip it's orientation? :) I came across something to do with build.prop, could that be it? I've no problem editing it, just as long as someone more skilled than me says that it shouldn't cause another system meltdown. :D
[Galaxy Tab 7.7 Android Development] daniel_hk:
One more ting. Try to flash the latest pa_gapp( 20130524), there is a bug in the earlier gapps (20130331).

Good luck!
[Galaxy Tab 7.7 Android Development] AlexVallat:
Thanks. I think what I'll do, though, is leave it for a week or so with just the -s kernel and everything else the same. If I get the drain/heat again, then I know that -a or -s doesn't make any difference, and I'll give the pa_gapps a try next to test that theory.
[Galaxy Tab 7.7 Android Development] euror:
Using latest kernel-A wifi got disconnected when screen off for a while, where the 26 May rom don't have such issue.
[Galaxy Tab 7.7 Android Development] Nuclear Blast:
i think so - i saw it disconnected once or twice....
[Galaxy Tab 7.7 Android Development] Dolphin Trainer:
The A kernel has the same WiFi drain issues for me on my p6810 but the S version seems to have solved it (early days but so far so good).

Keep up the great work Daniel, if it wasn't for you I would've sold my tab.
[Galaxy Tab 7.7 Android Development] Earzor:
Any chance that connecting of hidden ssids comes back in paranoid? I hoped that any of the test kernel can do this. But both cannot it. :(

Same here.. DPI issue maybe..

I815

---------- Post added at 12:56 AM ---------- Previous post was at 12:39 AM ----------

I have had the same problem with i815 since April updates.. Lots of static and when playback volume is low sound stops. Its painful listening music or watching anything.. Especially while navigating on say YouTube, I hear static in between ui clicks.. It seems like an audio driver issue.. It kicks in (I hear the static) when there is sound, when there is no sound or playback (not the volume) not loud enough it goes to sleep mode or something.

Because of this I keep going back to earlier versions for my daily..

If you could look into it would be awesome Daniel, only thing keeping me from using latest all the time.. If not no biggie, you still are the MAN! :)

I815
[Galaxy Tab 7.7 Android Development] daniel_hk:
Don't know if bluetooth cause it. I'll look into Bluetooth later. It may redirect to the bluetooth for some reason. Try turning OFF Bluetooth and test if it is ON...
[Galaxy Tab 7.7 Android Development] czach5932:
3g connection

I was wondering if anyone with the i815 has had any internet connection issues. I drive a truck up and down the Midwest and no matter where I'm at I have poor connection. The best I've seen is 2 bars of 4g (which is fine) but for places that don't have 4g I am unable to get any kind of 3g signal regardless of network settings. As a comparison I have my rezound running tonked world edition with updated radio's and I have at least double the 4g connection and always have 3g when my i815 has no connection. Just wondering what (if anything) can be flashed with this Rom. If anyone has any advice I'd really appreciate it. I'm willing to test radio's if someone thinks that's the issue. Would be perfect because I go to many different locations and can see what works the best and where.

Alright sorry for the long message but I really appreciate the help, my tablet is my lifeline while I'm away from home.

I also noticed in pie mode the bottom 1/8th inch of the screen doesn't respond to touch (the same height of the bar that disappears)
[Galaxy Tab 7.7 Android Development] d0shu:
Tried it on and off, same static on Bluetooth headset and headphones..
[Galaxy Tab 7.7 Android Development] daniel_hk:
Most likely when I was dealing with the bluetooth headset issues. I need to trace back and have a look.

Can you specify which version/date began to have this static?
[Galaxy Tab 7.7 Android Development] paranoiadk:
Please forgive the offtopic, but I managed to work out the bootanimation thing.

I've posted it in the themes forum.

Hi. NTFS still not working?
[Galaxy Tab 7.7 Android Development] jkrell:
Using the "a" kernel, I've seen inconsistent battery usage in standby. Sometimes it drains at a rate of around 1% per half hour, other times it's 1% per 7 minutes. For example, last night when I went to sleep it was at 95% and when I woke 8 hours later, it was at 75%. I had WiFi, 4G, GPS etc. all on but even in that scenario under stock ICS I would lose 10% max in that amount of time, usually more like 4-6%.

Since I've been on the "a" kernel for 4 days, I decided to test the "s" kernel. I've installed and I'm charging to 100% now in order to test it. I'll report back what I observe over the weekend.
[Galaxy Tab 7.7 Android Development] ColBill:
A few of the most recent posts regarding NTFS are at 520, 574, and 577. I think the earliest post is around 60. Based on the traffic Daniel is still working to build the best kernel for battery life and a few other issues. It seems to be on his list of things to work but not sure where on the list. Hope this helps -another place to do research is Daniel's other thread CM10.1
[Galaxy Tab 7.7 Android Development] d0shu:
Last confirmed working one was April 17th version.. Then this static only occurred when device was charging after that update it started to happen always. This also happens during calls with headsets as well .. Mostly noticeable in quiet environments when volume is low. Doesn't seem to happen with speakers.. Also this happened at the same time with cm version as well..

I guess its i815 only issue..

---------- Post added at 06:59 PM ---------- Previous post was at 06:54 PM ----------

I also feel there is radio issue, but I thought we had to back to stock ROM and boot loader in order to update the radio and since that's not so easy didn't attempt it. I don't ever get full bars of lte and since I installed cm first day I am not sure if its stock is any better..

[Galaxy Tab 7.7 Android Development] edan1979:
you can flash back the official stock JB using odin... but after flashing you need to restore your device into factory setting/wipe all your data
[Galaxy Tab 7.7 Android Development] daniel_hk:
In 4.2.x the content of internal sdcard is inside the /sdcard/0 folder. you have to move the content back to /sdcard after you restore to 4.1.x.

Daniel, issue of battery drain It's still there.

89%--->78% in night idle|stand by mode ( 7h) with Wi-Fi and Mobile data on, GPS offcourse off.

This problem, as we have all noticed, is unsustainable. Sometimes - there it is, sometimes - there it isn`t.

Theese results - with new kerenel-A version and of course last Daniel`s PA.

I continue to monitor further with kernel-S!

But no matter what, thank you for the great job and a stable support us and our devices.

, Man!
[Galaxy Tab 7.7 Android Development] Nuclear Blast:
Result with new kernel-S.

One night through.

48%--->44% in night idle|stand by mode (8h 30m) with Wi-Fi and Mobile data on, GPS of course off.

Theese results - with new kerenel-S (02.06.2013) version and of course last Daniel`s 3.56 PA.

I continue to monitor further with kernel-S because of nonstable observations with kernel-A.
[Galaxy Tab 7.7 Android Development] roninxxx:
Same here .

With kernel A there was high energy consumption in stand by and i even have to reboot the tablet because the screen won`t turn on .

With kernel - S everything seems fine after 24h .

LE - it`s P6800
[Galaxy Tab 7.7 Android Development] jkrell:
Same here as well. I've been on the "s" kernel for 48 hours and the results are impressive:

RIght now, I've been on battery for over 18 hours and I'm at 73%. During 9 hours overnight, I only lost 4%. Similar results the night before.

I know both kernels are supposed to have the same power management, but something definitely seems better with the "s" kernel. Could the drain be happening somewhere else, not in power management specifically?

I'll keep observing, but right now I could not be happier with this ROM and kernel combination!!! :highfive:

TO BE CLEAR, i815 with WiFi, 4G and GPS all turned on at all times.
[Galaxy Tab 7.7 Android Development] kaijura:
There are a couple issues I want to mention after using PA for awhile (1 month). I didn't get logcats of the issue yet since they are not major. Overall, it is stable and I never got reboots.

I notice the IME switcher in status bar function is not working properly, the toggle in pa settings doesn't change it. It works fine when changing directly in language settings.

After recording video with camera for awhile the system color scheme changes, like hue settings got inverted to magenta/green. It needs a reboot to restore the default color. The video isn't impacted, only the screen. I'm thinking it has something to do with auto settings in camcorder/camera.

---------- Post added at 02:54 PM ---------- Previous post was at 02:51 PM ----------

Here's what Daniel said in the CM 10.1 thread:

I'm not sure if this means it's based on the "a" or "s" kernel/wifi driver. Daniel can you elaborate please?
[Galaxy Tab 7.7 Android Development] daniel_hk:
I was busy at work lately. Sorry for not clarify :o

Kernel updates are temperate. Will be included in rom release later. However, all the kernels will be kept in goo.im. (http://goo.im/devs/daniel_hk/rom/kernel) and http://3djanos.com/daniel_hk/index.php?dir=rom/kernel/

Change log for latest kernel 20130609:

1. New power management and a few kernel drivers to fix the Power off charging issue.

2. Cherry pick the best part of both “s” and “a” wifi driver to provide a new wifi driver. (hoping to have better signal and power consumption)

3. New WiFi firmware fw-4.bin.

4. GPU max. freq. upto 400Mhz with new r3p1 blobs.

This kernel will be included in the coming PA3.60 build. PA haven't released the Halo source but some changes already made and cause error at build. It requires a few patches to complete the build now... It'll take longer to build and test before release...:cyclops:
[Galaxy Tab 7.7 Android Development] jkrell:
Thanks for the update, Daniel. I'm going to continue to test the "s" kernel. Maybe when 3.60 comes out, I will do a backup and test. Everything's perfect for me now so I don't want to mess with things for the moment.
