Weird battery/connectivity behaviour

After switching from 2G+3g to 2G and back again a few times (wifi off), and draining my battery (to around 20%) listening to streaming music, I arrived at work and turned WiFi on. Suddenly my phone could not connect to the mobile network (WiFi was fine).

I tried everything (toggling aeroplane mode, 2G+3G and 3G, WiFi, and screenlock* using the power widget buttons in the notification drawer) and restarting, but mobile connectivity did not work.

First log: http://db.tt/ESYUFpMH

Then my battery jumped from 14% to 0% and the phone switched off. After I plugged in the phone and I restarted (and maybe toggling some more notification drawer buttons), everything was fine: battery was at 0% and charging, and mobile connectivity was back again.

Second log: http://db.tt/SOtdALrf

I am currently running KKe124 and CM10 'Look Ma'....

For some reason I can never find the Last Kernel Log. I can never check it in the SysLog app.

*screenlock has been giving me problems before: http://xdaforums.com/showpost.php?p=41782469&postcount=5624

Hi, for a couple of days I've tried kk124 and tonyp rom latest, all was working fine but now my phone is very slow and sluggish even when I reboot it's start sluggish. Anyone has this problem?
[LG Optimus 2x] @ltaf:

[LG Optimus 2x] saaavikk:
There are known performance issues with kk 124. For maximum performance use 122 with 019 kow. manager. :good:
[LG Optimus 2x] pengus77:
Sounds like some rom-space problem though. After a reboot all the kernel space ram is happily cleaned and wiped. So it actually can't be laggy right away if it were a kernel problem...

Instagram Video

I tried three different ROM's to use video on Instagram, but it didn't work on any of them (PA, CM10.1 and CM10)

So i guess is kernel related... probably because of the RAMhack

Any ideas?
[LG Optimus 2x] DrummerMuppet:
Can't tell for sure. From the reviews on Playstore, Instagram seems to be having issues to record videos on several devices so it could be app-related instead.

Try using ROMs that do not include KK and see if the problem persists or not.
[LG Optimus 2x] pengus77:
I handed yesterday the 125 release kernel to the testers. Waiting for the final reports. All good so far, so i'm confident the no-data bug is gone for good. Also, 125 will fix dynfsync for everyone as a bonus. Call it a bugfix release, but i think it could safely be named the next stable if all is good also for you all ;)
[LG Optimus 2x] kekks:
Wow sounds awesome, waiting patiently for the next release. :)
[LG Optimus 2x] clashman90:
No friends, many related to social media applications. Are failing (Facebook, Vine, Instagram etc. ..). But not the fault of the ROM or Kernel.

Since these failures are also discussed in the ICS ROMs.

We will have to wait for a new version of the application or use an older version.

Greetings.
[LG Optimus 2x] chp2:
Good to hear that. I'm impatient to test it too with several ROMs.
[LG Optimus 2x] pengus77:
Experimental Release (125)

Guys, at last, i just hope this one fixes the data loss. We tested for A LOT and seems all fine. Also dynfsync is fixed for good. Call it a bugfix release and nothing more. If it's all stable i'll re-release this one as M1. Say bye bye to the 100pX naming for stable releases, i'm moving to the milestones naming scheme, while keeping the incremental for the experimentals. Way less confusion ;)

Anyway, it's up and ready in my XDAFileServer folder. The link is in my signature. Have fun ;)
[LG Optimus 2x] Patrick Morgan:
Yep, Now thats its available I can say its as solid as 124,

Been testing it the last couple of days, and did some more heavier testing on the mobile data and signal in different situations and times last night.

T.build 4 in that time has been wonderful. still doing battery cycles, but its so nice.

Gotta hand it to Team Penguin. Kudos

That's awesome man! Thanks a lot. Hope this community will continue for a long time, it's really enjoyable. Very offtopic but maybe I will start to make my own theme this summer, I want a light one like LG made because everything is more visible then, but then offcourse less ugly and way more clean and stylish.

Anyway, trying now. Thanks for keeping up this community and putting such a nice effort in this project Pengus!
[LG Optimus 2x] Patrick Morgan:
I'll add some pics to help.

I personally dont have PSP mode on my router, but if you do have it ,change that option.

I'm pretty sure thats the basic layout of the recommended settings. change LEDs and other settings as you see fit ^.^
[LG Optimus 2x] x_justin:
Well, I think Kowalski Manger is there to adjust the settings to your wishes! But speaking for Pengus, you can now safely enable dyn fsync.

[LG Optimus 2x] DrummerMuppet:
Yes, it should be fine now.
[LG Optimus 2x] Patrick Morgan:
AFAIK, all of the testers (myself included) have been running with the above settings (give or take psp mode and that for preference)

in the last few days no network problems have been found, across the different Roms we've been using. - Which is why 125 has been released.

If we found problems, the release would not have been released ^.^

Fast charge

Hi Pengus, thanks for keeping this phone humming along!

Just an idea,

Would it be possible to do an "Auto" setting for charging?

i.e. start as "Slow charging" and if in a period of time, no usb connection is discovered, change to "Fast charging"?

Regards

Rex
[LG Optimus 2x] sgspluss:
Do you think i know in which there 633 pages i can find this answers?

If anyone know the answer i will be thanksfull for an short answer.
[LG Optimus 2x] Patrick Morgan:
I dont want to sound rude. but you are filling the thread up with questions. Using the search system provided on the forums is a great way to speed up your own learning.

it might take you all of 10 minutes to search, (OMG 10 minutes of my time wasted looking on search) in comparison to the MONTHS and MONTHS of work Pengus has spent building this Kernel.

so in some way you could appreciate his work, by learning yourself, by searching in the fourm, (using search) and not insult the Dev with questions thats been asked before.

but to answer since your Too Lazy to read some google pages.

Dynfsync, - speeds up read and write speeds, helps the phone do things faster.

and 2nd core hot plug, allows the 2nd core to sleep, and save power when the screen is off.

if you just wanted a basic answer there you go. if you want more info. use google and search and stop filling the thread with repeat questions that have been answered, and only require a few minutes of your time to research.

Please.
[LG Optimus 2x] sgspluss:
Mate just quick answers like you have given. This are perfect and answers my question.

Well i dont will an dispute here so i just say thank you for helping me. ;)
[LG Optimus 2x] DrummerMuppet:
No, I don't think anyone knows the exact page - that's why I asked you to use the Search function. It's quite useful, you know? Your excuse is not valid, you're just being lazy. What an attitude.

Hi Pengus, when screen is off, I can not wake it up while I charge or connect to PC, I am using KK 125 but KK 122 is ok, this problem is related from Kernel or my phone sir? I am using ROM CM10 "Look Ma! No Hands!" Edition.

Double checked using boat browser, and the Server shows up, and i'm currently downloading the Old BL over Hsdpa no probs at the mo.

make sure you've cleared both caches before you've flashed the new kernel, and fix permissions for good measure,

connecting to PC, or mains, and doing some very silly, jumping about with my phone, while switching airplane, wifi, and network modes while plugged in and not, i've not been able to cripple the phone, or network. ... but i like challenges ^.^

strange (and funny)... in the xda app, link doesn't work for me using dolphin/stock browser, but if i go and copypaste it into the browser, it works...

nevertheless - i've installed kk125 and enjoying it :)
[LG Optimus 2x] Patrick Morgan:
probably a bug in either of the browsers, or the XDA app itself, - clearing their caches may sort out the issue. just checked opening the link in the XDA app, and it opens fine still in my default browser (boat) ^.^
[LG Optimus 2x] SugarFreeMilkTea:
I've done a Chinese translation for Kowalski Manager 20. Maybe you can add to next release. ;)
[LG Optimus 2x] 60nine:
tried clearing the cache in xda app - same thing... browser is set to clear cache & history when closing...

i'm not a noob, i try everything possible before i report something :) this worked well until now (i recently switched from tony's PA13 to his cm10.1 latest)

btw i know the benchmarks don't say much, but i had 7300+ in antutu yesterday on kk124, today it's 5600+ (same 216-1200 mhz setting) - one run, i think it got stuck on 3d benchmark a bit...
[LG Optimus 2x] marck90:
My screen is ''flashing'' it turns randomly on. Installed 125 a few hours ago worked great, but now i got the flashing screen :eek:
[LG Optimus 2x] Luk_Optimus:
It happened to me too (that the screen turned on), but i think it happened also before kk125. I tried to reproduce it but it didn't worked out. Will try to fetch some logs next time...
[LG Optimus 2x] Justray:
Happened to me with Tony's PA, but now I'm using T-Build 4 and so far no problems

This kernel is almost PERFECT, the only thing it could need would be a 32+ramhack, 64mb ramhack would be AWESOME!, but I'm ok with more than 32mb :D but if you surprise me with 128mb I would donate a 50 bucks instantly because you basically increase this ol' phone life span another year :fingers-crossed:

Very good that one. Well done Pengus.

Had to test it a bit before posting and it look like that one is the one... Finaly.

[LG Optimus 2x] Patrick Morgan:
Please make sure you have cleared both caches before flashing the new Kernel, and fixed permissions for good measure.

It could be something persisting through from your previous configuration.

If this still does not work, please take a nandroid of your current rom, and do a full clean install and test again (even as far as reformatting drives with the AIO tool). ... .... .... then using nandroid manager Like this one, or a similar app, restore just your user apps, text messages, and call logs. if needed.
[LG Optimus 2x] kekks:
This seems to be awesome kernel, perfect, temple runs super smooth with this kernel now.

[LG Optimus 2x] Kinimod01:
Very stable... Extremely fast with recommended settings... Great Job!

For me it even seems to be faster than exp124... But I guess that is due to the activation of fsync, which I have not activated before...
[LG Optimus 2x] extreme79:
Hi!

I have an issue.

I usually leave my phone on charge during the night in airplane mode. At the morning the alarm app ring and automatically turn off airplan mode, and this is ok.

Then, If I try to turn on wifi.. it seems to be locked. It stay in "turning on wifi" state, no wifi detected, no way to switch on/off wifi.

Turning off/on data or turning on/off airplane mode or change network mode (2g/3g) has no effect. The only way is a reboot.

I think airplane mode is the key, but sometimes seems to happen without airplane mode switching.

I got this issue since kk124.

Already reinstalled kk125 after cache/dalvik cleaning.

Someone experiencing this issue?

In the afternoon I'll post my logs, if you think is useful.

(I'm on penguss CM10 new BL not tonyp cm10.1)
[LG Optimus 2x] jcdid:
Hello,

I had 3G/data issues since kk122 to kk124 (PA12,PA13 and this build too, with a lot of different combinaison set in KM). I revert back to kk121.

kk125 installed yesterday for test, all was working fine, thought the issue was solved since this morning, 9.30Am (Bluetooth connected to BT car system). The only way to recover => Reboot ! (KM setting : 2nd core hot plug YES, Fsync OFF, Max Load Balance )

Collected SYSLOG before reboot (not sure that's is kernel related right now..) and uploaded last_kmsg.log if it can help us.

modem.log reported a lot of

REQUEST_GET_NEIGHBORING_CELL_IDS error: com.android.internal.telephony.CommandException: GENERIC_FAILURE

Let me know if you need full logs.

Except this issue that remains, all is working fine, smoothly and stable, thanks for your job ! ;)

[LG Optimus 2x] jcdid:
Sure I can try this , however :

- I never had this issue on GB, ICS , PA or CM10.1 with kernel version before 122 (still stay in V30A NEWBL)

- No issues during WIFI/Airplane on/off, data switched to ON automatically

- Comparing radio logs, mine seems a little bit different than them reported in this post..(but i'm not a developer; not really sure.. :( )

- My experience is network data lost appears each time after a long dep sleep period, or driving with bluetooth (and GPS) on.

Before erasing CAL procedure, revert back to 121 for me.. I trust Pengus to have a feeling on :D
[LG Optimus 2x] DrummerMuppet:
[MENTION=2515119]jcdid[/MENTION] [MENTION=5024751]saaavikk[/MENTION] you both mentioned that after using bluetooth you started experiencing data/signal problems. AFAIK, this is a known issue on Tony's CM 10.1 (builds 4.7 and 4.8). What ROM are you guys using right now?

Please, try to be more descriptive when reporting issues. This does not help at all. Details are important.

What ROM are you using? What do you think triggers the problem? Were you using bluetooth before the signal drop?
[LG Optimus 2x] jcdid:
Sorry. :eek:

Tony's CM 10.1 Build 04, kk125, BB V30A

KM : 2nd core auto hot plug ON, Max Load Balance PM set, Dynamic fsync OFF (tested multiple configurations)

Bluetooth always enabled on my 2X.

Appears for me usually :

- after long deepsleep (bluetooth ON but no device connected)

- Driving with BT car device connected via bluetooth, GPS ON and permanent data transmition (WAZE)...

Application returns "Search for network", network status bar stay on state (no signal variation).

I double check via phono application, Data are OFF and quality signal still stay with the same value..

Only reboot to recover..

uh oh... i have two things to report, tonyp build 4 and 125exp

Today I have set the single core mode, hotplug activated, then put my phone to charge (AC), found that it was later down to battery recharge screen before boot.. somehow it powered off. Then i booted again being in charge, went to do some things and when i was back i was in charge mode again.. now i have disabled it, let's see

Second thing is that battery charges fine but when it says full charge it's only at 3.8V average in battery analizing software.. then fast discharges 10-15 % in 30 minutes.. no app involved in this. I can litterally see my bat going down 2-3% at once.. i'm on original fresh battery. It started after 125 update.

kind regards
[LG Optimus 2x] tonyp:
The weird battery drain is probably due to the charger binary (for the offline charging screen) being totally ****ed up.

I recently had to use offline charging for ~2min (as it wouldn't turn on again without) - after booting it told me it's at 78%.

Obviously you can't charge 78% in 2min - thus the battery drain has been "enourmous".

It even dropped while it's actually been attached to the wallcharger, and took quite some time to adjust itself.

Regarding your issues: check if you can reproduce them without the single core options. If you do I'd claim some data corruption.

tl;dr: try to avoid charging the phone while it's powered off!
