Having recently upgraded to a smartphone ( Galaxy Note ) and starting to find my way around and rooted my GB, i decided to flash to AbyssNote Kernel and i see a speed improvement.

What i'd like to know is should i have wiped cache and davnik cache each time you change Kernel ... ?

Many Thanks
[Galaxy Note GT-N7000 General] eliashadow:
As Kernel masters sais its not needed.

But its not bad too.I always wipe cache/dalvik before a kernel installation.
[Galaxy Note GT-N7000 General] Flex Developer:
So its best to wipe cache/dalvik before kernel installation or after kernel installation. I have been using PC Odin to flash kernel so far.

Many Thanks
[Galaxy Note GT-N7000 General] eliashadow:
Its not good to install custom kernel in pc odin.Probably now you have yellow triangle in boot (i dont know cause i never install kernel via pc odin but i know that the only i we can install via pc odin is a stock firmware).

Install kernel via cwm recovery (of course you need to root your phone and then to have custom cwm recovery) or mobile odin from google play.

I wipe cache/dalvik after installation.You need to remember that is good to reboot your phone 2-3 times after installation as many devs suggested.
[Galaxy Note GT-N7000 General] Flex Developer:
Right ok ... Yes i do have the Yellow Triangle on Boot. Once i am back at home i will have to redo this again but using cwm recovery.

I will also wipe cache too ...

Thanks for the advice
[Galaxy S II General] qshoo:
I solved a problem with my custom ROM (WanamLite) on Galaxy SII I9100.

When I sent a SMS and the recipients mobile was offline at that time, my SMS gets marked as 'sent unsuccessful' about 10 minutes later. These messages had to be resent manually and if the recipient was still offline, the game starts again. On top of the inconvenience most providers charge every single unsuccessful delivered SMS!

There is one setting in SMS apps 'request delivery report' or similar, but this means to receive a report if a SMS is received successfully or unsuccessful by the recipient.

The time how long the provider tries to to deliver a SMS is quite an other thing. As far as I know there is no possibility in Android or any SMS app to set this validity period.

As a former developer of a Fleet-Management-System I remembered that there are settings in the SMS message format for this. Also some old phones have options for it. As far as I recall, the time span can be set from some minutes up to 7 days.

Long story short, I flashed Siyah Kernel and - all problems magically dissolved ... SMS are delivered up to 7 days after sending ...

Hi All,

Since updating my Note to the stock LPY ICS from stock GB, I have found that the bluetooth no longer automatically connects to my Car stereo to use it as a bluetooth headset.

Looking in the settings, the option for automatically connecting seems to have gone!

Has anyone else found similar issues or a fix?

first, I use aokp ROM and I flashed tablet ui.

but when I try to install/uninstall apps, my phone reboots(hot reboot, actually)

I can't find any thread about this.

If you have a free time, try tablet ui(for aokp m5), and try to install apps.

I have the same kernel wakelock l2_hsic in my phone when it is otherwise idle... no idea what it is though, but in my feeble understanding it means that the phone never gees into deep sleep - and that can't be good can it? :confused:
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] rigor.m:
I have the same problem of the l2_hsic wakelock popping up and eating battery. A reset always cures it for some time but it eventually appears again... Very annoying, I hope someone figures out how to get rid of it..
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] frasch42:
Same here, l2_hsic keeps my phone awake. It's seems to start at some random point and never "switches off" again until I reboot the phone. After a reboot it takes usually takes a couple of hours before this lock reappears.

Never saw this lock on GB, btw.

I'm having the same issue too. Has anyone figured out what it is yet?
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] frasch42:
I gave up.

Went back to Gingerbread using PC Odin and flashed a pre-rooted LA1.

Installed Mobile Odin Pro and flashed official LPY using Everroot and the 2 injects.

So far it has been running nicely with no wakelocks worth mentioning.

Disclaimer: I am a noob, what i have done might be unsafe and stupid.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] StarterKid:

i have a bunch of random kernel wakelocks that randomly start up and keep going. l2_hsic is one of the worst offenders tho.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] frasch42:
Update: Phone is doing great now, with uptime of about 36h.

L2_HSIC does show up in kernel wakelocks but only for about 10 minutes in this 36h period.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] StarterKid:
Yesterday it seemed like my note cured itself, the l2_hsic wakelock was up for about 10 minutes and after 19 hrs I had 45% left. Without changing anything today it is worse like before. The Samsung-Support did not know what to do except for a factory reset, but I'd really like to find a better solution.

It seems like a restart cures the wakelock for about 24 hrs. I restarted it 1 hour ago and until now the l2_hsic hasn't come up...
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] jrinco11:
you mention "2 injects" -- what are you referring to there? I did the LPY flash via mobile odin pro, but still have the l2_hsic battery drain issue, so perhaps I can try the '2 injects'?

this deep sleep issue is the reason i went back to gb. believe me this issue will keep coming. im aware that rebooting by turning it off could fix it, but once u charge ur note while awake it will lock at 200mhz again. so annoying,..
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] gaddy888:
You're right. I have the same problem. A reboot fixes it but it's always back when you least expect it. You only notice it once the battery is down by an inexplicable 20%

How do we bring this to the notice of someone who knows how to fix it.

On gingerbread I have other wakelocks. "gps" and sometimes "fuel_alerted".
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] αкαѕнα:
I joined the club and have this strange wakelock too ^^

Only 4,6% though, so it's no battery drain but regardless of that i was curious and wanted it removed :

Hope there is a more permanent solution for this than rebooting O.o

I use the LPY rom together with CF-Kernel LPF. I had the l2_hsic problem too. For me reflashing the kernel with mobile odin resolved the problem.

When on charger, it's always awake at 200Mhz...

I've read somewhere that if you unplug from charger with the Note in "sleep mode", it will not enter Deep Sleep.

I had the fuel alerted wakelock because the bat was down to 5% and charged it and unplug it while screen off.

Also had the "no Deep Sleep" problem, but after I've started to wake up the phone prior to unplug the cord, it sleeps like a baby (2 days with usage) and always deep sleep when screen is off (checked by spy cpu).

Hope it helps...

[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] guppyworldwide:
Unplugging while "Awake" is not the solution.

My phone goes into this permanently awake state randomly after upgrading to ICS. (I am stock, and upgraded via Kies...never messed with this phone before). I too noticed the L2_hsic taking alot of time.

I have made a concious effort to investigate this, and I can confirm that unplugging the phone while "awake" as a solution is false.

Not once since I discovered this problem have I unplugged while sleeping, but alas, I am again in a zero deep sleep situation.

Back to restarting this stupid thing every 2 days after finding my battery draining 15-20% in some short minutes.

I abslutely love this phone!!! Best in the world hands down!!! I love ICS!!! But if this problem doesn't go away, I am giving up! Samsung is both the best...and the worst!

Guys every time you open/use maps, go to latitude and sign out of it. I'm almost 100% sure this is the issue. I've tried this time and again with LP8 and LPA.

Until I'm signed into latitude, l2_hsic raises it's ugly head randomly. Signed out and it hasn't crossed more than 15 mins. I don't boast of a 3 day battery life, I'm a heavy user. Get about 18 to 20 hours of heavy usage with mails and fb sync on!

Can somebody give this a try and observe?

Some accidental discovery and "live" stats:

1. Battery is at 68%.

2. L2_HSIC appeared 3 minutes.

3. Unplugged for 15 hours now.

4. Did the usual call, SMS, web surf, email sync (5 accounts). No whatsapp, no FB.

5. Bluetooth is on all the time but not used.

6. Deep sleep is at 12 hours

Key difference from those days when my battery could only lasy 10 hours: 3G/HSPA has been turned off during last 15 hours. Wifi has been on because I am tethering my SGN off my HTC Desire hotspot.

Why? Because I am overseas now and don't want to turn on my 3G/HSPA roaming.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] gaddy888:
After getting completely frustrated with the situation, I tried updating the phone to the latest Indian rom. But it wasn't supported in kies and didn't work from the phone either. Tried rooting the phone and installing Cwm. Rooting probably worked, but after installing cwm something clearly had gone wrong. Wifi stopped working. Decided to download the rom from Sam mobile and install with pc odin. That process failed. I believe the files were successfully pushed but could not complete writing to the phone. On restarting I was greeted with a message saying something like update has failed and to try recovery mode in kies. Tried that but nothing happened.

Finally gave up. Went to the Samsung service centre. They didn't suspect anything was wrong (custom firmware-wise) . They loaded lp8. I installed the latest update available ota.

Now my phone runs like it's never run before. Smooth, battery life is great. No wake locks. So far.

Maybe you guys should try and take the phone to a service centre. Samsung needs to know this issue exists and affects many people.

There were at least 3 other people there with some issue with firmware.

Clearly QA is not their top priority.

Observations , no solution

Hey Folks, I am new here and new within the Android World.

I know that we have got an Galaxy Note ICS thread here , but I think I need to share my observations on the same problem with a Galaxy S3 and (obviously) ICS.

Getting my Galaxy S3 I started checking wakelock things and so on with "better battery stats" . I set everything just fine and did not have ANY problems. Up to 30 Hours standby (mid heavy usage!?) .

To come to the point:

Just today I updated several google apps. And there we go with the "l2_hsic" wakelock at about 4% usage giving a 40% awake time without using the phone. Updates were :google+, maps , street view and the (final?) google chrome stable version...

I cant find any explanation for this wakelock as said in the title , but I´d say that this has obviously to do with some google product. I do not know of any settings that were changed after updating , but something must have been changed - starting to stray around in app settings and hopefully find something.

greetings
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] shaftenberg:
Although I repeat myself for a few times now:

l2_hsic has nothing to do with any app! It is a kernel service which pops in at data usage over 2G/3G.

Sure, the gApps do need heavy data transmission, so it is likely to get an error when using these.

As location services are using data too, maybe there is a connection, but it is not gApps itself. Try Shazam instead, it uses location every time you start it and I am sure you'll get a crazy l2_hsic wakelock too someday.

As other users reported: freezing Maps was not helping to solve this issue, am I right?

[edit]

Which ICS version are you on the S3?

My gApps are old, got G+ 2.5, Maps 6.7 and nothing else.

I not sure whether this affect the l2_hsic, but once i disconnect from this wireless device and it back to normal.

My ROM is RR V7, LQ3 + LR1

Scenario 1 @ Home:

Wifi ON (Connected, Brand-NOT LinkSYS), 3G Data ON, Location Service ON - NO l2_hsic issue

Wifi Settings: WPA2-PSK

Scenario 2 @ Public:

Wifi ON (Connected, Brand-Unknown-Public), 3G Data ON, Location Service ON - NO l2_hsic issue

Wifi Settings: Unsecured

Scenario 3 @ Office:

Wifi ON (Connected, Brand-LinkSYS E2500), 3G Data ON, Location Service ON - l2_hsic go wild

Could it be wireless router issues???

my l2_hsic ONLY go wild whenever I connected to Office wireless

I am pretty aware of your discussion over the thread shaftenberg.

Maybe I made my self not clear enough at the " everything was set just fine".

The only thing changed up on the phone was updating the mentioned apps.

yesterday I deinstalled the recent updates and i am pretty sure the issue is gone. I still have the l2_hsic on my better battery stats kernel wakelock BUT it dropped to about 0.5 percent with an uptime of 48 seconds in 12 hours.

and as i said. observations, no solutions.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] Tonio78370:
For me it's clearly a WiFi issue.

I had the problem over the last two days and it was every time around noon. Why? Because I leave my office to go to lunch.

The change of location (and WiFi network) seemed to trigger this L2_hsic issue. Today I cut WiFi when I left my home; I just come back to the office and still no L2_hsic trouble.

My GNote is running for almost 9 hours and used 19% (81% left). 7h45m Deep Sleep, 0h39m 200 MHz. L2-hsic only ran 0h12m7s during this time.

I'll get back to my "old" habit and cut WiFi when I'm not at home and I'll be alright :cool:
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] MichelDiamond:
Some people mentioned different this about the wakelocks... also the way of charging. So I searched in the APIs and the configurations.

It's really hard - as this problem makes it difficult to make a difference between "cause" and "effect". And a time delay between cause and "wild l2_hsic"

So the "effects" are sometimes others, I think WIFI is one of the effects. Device gets warm - battery gets warm - then somebody who has a SD-card inside, which doesn't get up with this temperature gets strange secondory effects (like restarting the launcher) and so on.

So I used an analytic method since the last three weeks on my Note... it sometimes gets warm, but all were "effects" (btw: Apps can't be really the cause).

At the moment I only saw one cause - but time delayed:

"Put the USB cable into or out of device, while Note is locked"

Then l2_hsic-problem occured within the next 24 hours.

It makes sense...as we know, that usb-port can do much more as only charging... and there seems to be the "cause", which also internally has effects on Data connections and then this two things together are responsible for l2_hsic-problem.

I'm not sure at all, especially if "put USB-cable into" or "take USB cable out of" device while locked.

Has anybody also "tested" this scenario and waited 24 hours?

Nevertheless: Samsung has to solute the problem - I already wrote to Samsungs support - and the more users will do that in their countries - the more Samsung will be aware of that.

Please simply jump to "http://www.samsung.com - then to the contacts/support of your country and choose the Note (GT-N7000 or whatever it is named by Samsung).

I think they need a bit pressure to solute it...

As while: I hope the while to avoid the locked-scenario can make it better

I just had this, phone lasted a total of 12hrs since last change, with a night in the middle, and this morning I didn't almost use it, except for a short read with ezPDF.

I didn't connect it to usb in the last 24hrs, nor I connect it via USB, ever, unless it's to copy over a new rom file.

I always switch batteries when they're dead, have a stock of 4, the original plus 3 oems, and obviously a wall mains charger.
