Different RIL.

And our RIL might have the same minor issue that the Infuse RIL did in which HSPA+ was reported as only UMTS - so if you were in a non-+ HSPA mode it would be H, if you were in 3G it would be 3G, if you were in HSPA+ it would be 3G. This was a display error... Do you notice any significant differences in actual data speed performance between CM7 and stock firmware?

(Actually, you could still see slow data if the CM7 tree uses older TCP buffer size values.)
[Windows Phone 7 Q&A, Help & Troubleshooting] jlahr001:
Hi,

I have been trying to use convert the log file from GPS/GPX viewer but find that the GPX file contains no data and the .csv file is unusually formatted.

Does anyone know what format the .csv file is or why the GPX file only contains a few headers and an XML markup but no data. I was not permitted to include the URLs or data.

The csv file contains the data but specifies it in an unusual manner for example:

Latitude and Logitude are specified as 6	9.90E+13

Does anyone know how to make sense of the data? It is reported fine on screen.

Ideally I would like to know how to convert the data with GPS Babel.

Thanks!

I have a Nook Color rooted with CM7.1 RC on an8 gb micro sd Kingston class 10. I have Netflix, YouTube(v2.2.14). Is the NC capable of outputting HD using a MHL (micro usb HD link) to HDMI converter cable? Have any of the nightlies addressed this issue? Thanks.
[Nook Color General] hololight:
Mhl requires special hardware, not just software. It will never be supported on the nook.

The photo below is an image of my phone displaying a light grey image in a dark room. The yellow tinted gradient on the left hand side is very apparent, but that is not what bothers me so much. If you carefully notice the area demarcated inside the red box, you will notice a horizontal band that is of a slightly darker grey. Is this a burn in? I have only had this handset for a couple of days, so I can't see how I'm already being affected by this phenomenon. One can also see how uneven the display is, overall.

hey guys im not liking the 5 mp camera on my atrix has any one thought of finding a 8 mp phone camera from like a parts store and installing it in the atrix?

or is there anyway to make the stock camera create better pictures?
[Atrix 4G Q&A, Help & Troubleshooting] malfuncion:
What app are you using at the moment to take the pics? Are you using the stock Motoblur camera app? If so, there are NUMEROUS threads about how it sucks and people have found nice replacements in the market. Use the search function.

as for hardware replacement, as easy as it "sounds", its not. You would have to hope you can find a camera that is based around the same hardware as ours so the factory driver would work. Otherwise you will have to hack/mod/code for the new cam to work. All in all, not worth the cost of admission. It'd be easier to wait for a new phone to come out with a 12MP cam which seems to be the upcoming US Standard for 2012.

Title says it all...

I wanted to use the lockscreen mod that madd had done and noticed I need to flash a deodexed rom to do this.

If I flash the stock deodexed rom... will I notice anything (performance gaines) by doing so? Or is it ONLY sot hat custom mods can do their thing.

Thanks!!

-RR
[Samsung Epic 4G Touch] Epix4G:
It actually takes a little longer to boot a deodexed rom but if you wamt themes and some mods must have deodexed rom
[Samsung Epic 4G Touch] madsquabbles:
it's pretty much for modding & theming. plus the first boot up will be slow on deodexed roms. the following boots will be faster. deodexed also take up a bit more space i believe because the files have to be decompressed in the cache.
[Samsung Epic 4G Touch] h20wakebum:
That makes sense...

So flashing a deodexed stock rom is not neccesarily going to give me a performance boost but will allow for customization.

I'd wanted to try using the custom lockscreen mod from madd so I flashed the deodexed stock.

The modded lockscreens are pretty sweet.

Just wasn't sure if I was gaining anything else.

Android os is slowly eating my battery.

Is this happening to anyone else?
[AT&T Samsung Galaxy S II SGH-I777] sweetboy02125:
Yup. It's taking 50% drain of all other services on my phone
[AT&T Samsung Galaxy S II SGH-I777] dayv:
Android os is near or at ths top of the list of battery consumption on my phone most of the time. But I'm not to concerned about it because I'm getting excellent battery life on this phone so far. It exceeded 3.5 hours of display on time before I had to recharge the battery the first time.

I wouldn't get too excited about battery stats until you have had your phone for 4 or 5 days and get settled into normal use and have completed a half dozen our so recharge cycles because the battery stats will not be very accurate until then.
[AT&T Samsung Galaxy S II SGH-I777] roadrash7:
Yeah im getting good battery life so far too but if it didnt have this issue we would be getting excellent battery life. In six hours of very little use its sucked down 21% and ran for over 30 minutes.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Android OS is at 47% for me.

I'm wondering if it's some sort of reporting bug, because I'm still getting excellent battery life. With debloating to kill all the background services and some minor power management tweaks in the kernel, it's doing significantly better than Serendipity VII did on the Infuse, which I didn't think is possible.

Usually at my desk in weak signal, Cell Standby is #1 and Phone Idle is #2 on the Infuse. They're #2 and #3 respectively for me.

I wonder if it's a dual-core reporting bug, because I've NEVER seen it over 50%, and if you ignore it, the remaining items in battery usage are consistent with what I'd expect to see for a device in the conditions I'm putting it in and the battery life I'm getting. It may be that for every item that wakes up one CPU core, it gets counted, and Android OS gets counted equally on the other CPU core.
[AT&T Samsung Galaxy S II SGH-I777] WillEat4F00d:
This is the same problem that the Sprint's version faced. There's a few long threads about it over in their section.

When I had the Sprint version, my AOS was random after each nightly charge. It would be really high one day, then really low the next. I've noticed that I get the best battery life when AOS is 2x%.

This is the first day after a full charge for my at&t version and AOS is around 2x%. 9h on battery and I'm at 70% with little - moderate use.
[AT&T Samsung Galaxy S II SGH-I777] eep2378:
I've been unplugged for 13.5 hours and I'm still at 74%. Auto brightness ON, 1hr 20 min display time. My Android OS is 18%. Thats way better battery life than I was getting with my Captivate. I'm stock right now(no root, kernel changes for now ;))
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
I was at 88% after 9 hours on my desk - that's pretty good considering the weak-signal conditions at my desk.
[AT&T Samsung Galaxy S II SGH-I777] ZeroIsntTheHero:
There is a similar situation with my LG Thrill. I haven't really monitored the battery usage on my SGS2 yet, but I'm thinking that you may be correct in questioning the dual-core issue. My only hesitation in saying that is that I don't have the same issue on my Atrix and it, too, has a dual core.

Android OS is currently at 21% for me(n my (SGS2), but I'm using my Atrix as my primary phone at the moment. So, it isn't being used excessively.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Probably not a universal bug with dual-core, but some firmwares may not handle it properly.

Android OS hit 60% last night - but losing only 2% in 5.5 hours.

For me, the higher it is, the better my battery life is.
[AT&T Samsung Galaxy S II SGH-I777] tycon:
I think that you are missing the math. if your usage for the OS is at 85% it is telling you that since you have been on battery and have 10% of your batter used, 85% of that 10% was the OS. This is what you would expect of it was let's say idle. The OS is what makes your phone work. If you have had your screen on it may say display.Mine is voice calls.

Does that make more sense?
[AT&T Samsung Galaxy S II SGH-I777] damon20r:
That was my thought on it also. It stands to reason that if there isn't much usage from apps and services then the majority of the usage would be from the OS which runs the phone and is required for the other apps and services to run on. It doesn't mean that it used a lot of power but rather that it used a high percentage of the power that was used.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
No. You don't seem to have heard of CPU deep sleep states.

The OS won't use battery if it isn't running at all because the CPU is halted.

On most devices, Android OS usage being high means that something is keeping the CPU out of deep sleep and it's such a "generic" cause of sleep failure that the battery usage app can't tell what kept the CPU running. Battery drain here will be high because the CPU is always running instead of halting and going into a deep sleep state.

"The OS is what makes your phone work" comment indicates you don't understand modern power management. The idea is that when it doesn't have to do work, the OS and CPU are NOT working - the clock is shut off, and core voltage is shut off, until an external interrupt (whether from a wakeup timer or external device) wakes it up.

The radio, however, will always be using battery in order to maintain communications with the cell towers. So in an ideal/normal situation, Cell Standby and Phone Idle should dominate battery usage, especially in weak-signal conditions where the phone's transmit power is cranked all the way up to try and maintain communications with the tower, while the CPU is halted and consuming almost no power.

However, in this particular device, Android OS usage is extremely high but without evidence that the CPU is staying awake. Simply put - Android OS should NEVER be higher than Cell Standby for a device that spends the majority of its time idle with the screen off in a weak-signal condition - in those conditions the radio should be dominating the power consumption. In the case of my device, it DOES seem to be dominating power consumption based on pure drain estimates, but battery stats falsely thinks otherwise.

As an example, in the best battery life I ever got with my Infuse sitting at my desk at work, Cell Standby was at 85%.
[AT&T Samsung Galaxy S II SGH-I777] damon20r:
I have a good BASIC understanding of power management, but no I don't have any experience or in depth knowledge about it really. But the OS is what all the apps run on and many of the services as well correct? The radios I would assume use the OS also but I guess could have some sort of standby that doesn't need the OS?
[AT&T Samsung Galaxy S II SGH-I777] roadrash7:
Isn't all we need to do is look in android os and see the cpu total time to tell if its running too much.

My phone has been unplugged 5 hours and is @ 67%. Display used 37% and was on for 1 hour. Android os used 29% so far and has ran for 36minutes, which is way too long. Normally a phone should not use more than probably 20minutes of android os for a whole day and drained battery. 35minutes of android os in 5 hours is way more than ive ever seen.

Post your cpu total times after a days use to compare and see what is high and low useage or if everyones is high
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Nearly every smartphone for many years has had separate CPUs for the radio and the applications processor. In fact some early smartphones were mistakenly believed to be "dual core" only because they had a separate radio processor. (Such as the ARM9 radio + ARM11 apps CPU of Qualcomm MSM7k chips).

The radio firmware runs on a separate CPU that is usually much slower and lower-power than the applications processor.

On Qualcomm-based devices, usually the radio CPU bootloads the apps CPU. In Samsung devices, the radio CPU gets bootloaded by the apps CPU on RIL initialization via firmware upload to an internal serial port connected between the two CPUs. Once started, the radio operates independently even when the main CPU is halted. The radio can wake up the main CPU with an interrupt when something happens that the main CPU needs to deal with. Similarly, the wifi chip can wake up the CPU with an interrupt when a packet is received.

As a result, when the phone is idle with the screen off, the CPU should be halted and powered down most of the time, waiting for an interrupt from a peripheral or a timer.

[AT&T Samsung Galaxy S II SGH-I777] Singuy1234:
I must be going crazy but this sg2 is killing me. I got it from Att yesterday and the battery life has been pretty HORRIBLE. (First time android user btw).

Sometimes the phone will eat up 10% of my batter life after only 90 mins of idle. I checked the battery usage and Android OS is at around 78%!!! How do I fix this problem? I downloaded OS monitor and didn't really see anything that uses a lot of CPU, except for certain files always syncing (but 2-3% usually). Checked with battery spy and apparently the majority of the time, the phone was hovering around 200mhz 70% of the time and not deep sleep.

It's sad to have only 1.5 hours of display time with a battery of 45% left (7 hours total time)...coming from an Iphone 3gs, this is just unacceptable. I almost flashed to the 2.3.5 firmware but noticed it's NOT compatible with ATT's version of SG2.

I see people who has a total time of 2 days AND a screen time with 3 hours with 30% battery left. I wish I can get half that!
[AT&T Samsung Galaxy S II SGH-I777] foxbat121:
No problem for me other than the usual calendar sync bug with Hotmail. I had this same issue on my Captivate when running leaked 2.3.3 ROM for Captivate. Basically, my Hotmail/Live calendar sync gets stuck in constant sync state and drain battery very fast. Disable the calendar sync for Hotmail and everything goes back to normal. I can't believe Samsung still didn't fix this bug.

[AT&T Samsung Galaxy S II SGH-I777] foxbat121:
If you just flashed a new ROM, you shouldn't compare battery states as it is invalid until either you calibrated your battery manually or let the phone calibrate itself in a week or so time.

BTW, the Hotmail calendar sync bug is a real issue. I found the same thing on my co-worker's GS2. You can go to Settings->Account and Sync, tap on your Hotmail or Live account and observe the last sync time and sync icon shows up next to calendar. It is constantly syncing. That will keep the cell data connection busy constantly and use a lot more battery than normal. It will also cause other account's like Gmail or real exchange account to constantly sync calendar as well. Uncheck the calendar sync on Hotmail account and reboot the phone and you will see it goes away.
[AT&T Samsung Galaxy S II SGH-I777] AndreiLux:
:p I wrote this thread exactly because of people like you. No offense.

I recommend everybody to just read this thread in the international Galaxy S2 forum.

There's too much fragmentation between the Epic 4G, AT&T and international version where too many issues are brought up in the first two where they've been already laid to rest in the latter one. Spread it around.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
The problem with your post is that there are people (such as myself) who are getting excellent battery life (better than my Infuse with quite a few power management tweaks) despite Android OS registering as 60%.

My best battery life run so far was dropping 10% in 12.5 hours, with Android OS at 60%.

"It's not fixed or fixable by any custom ROM, kernel, full ROM like CyanogenMod, MIUI, or newer versions of stock be it 2.3.3, 2.3.4 or 2.3.5. All use the same Samsung drivers."

This is clear evidence that you don't know what you are talking about. The drivers are IN THE KERNEL, and unlike previous Samsung devices, every driver in our kernel is fully open source. Therefore, if it IS a driver problem, it IS fixable in the kernel, because the drivers are a component of the kernel.

The exception would be bad peripheral firmware (such as the WiFi chipset), however, you don't have a single shred of evidence pointing to buggy peripheral firmware.

Edit: Your links to the Nexus S/Galaxy S Android OS battery issue are irrelevant. Different device, different hardware, and quite a few closed-source drivers. Almost zero relevancy to our device. Unfortunately Android OS is a "catch-all" bucket that almost any power management bug can add to. A symptom of high drain with high Android OS usage on one device will have completely different root causes than high drain/Android OS usage on another device.

In the case of the I777 - we have an oddball case where Android OS is impossibly high given all other evidence that is presented. Normally Android OS being high means high battery drain - but plenty of I777s have high Android OS usage and no excessive drain!

A key observation: In an ideal weak-signal situation, Cell Standby should dominate power usage. The CPU should be halted in deep sleep, but the radio has to keep checking in with the towers. There aren't many major optimizations you can do here - it's the basic laws of physics that you need to put a certain amount of power into your transmit amplifier for the tower to be able to receive your signal.

After a day at my desk, which is a particularly bad weak-signal situation where the phone bounces from 1 bar to no coverage regularly:

On the Infuse, Cell Standby shows up as 80% of battery usage.

On the GS2, Android OS shows up as around 50% of battery usage, with Cell Standby around 20-30%. However, actual battery performance is BETTER than the Infuse, with the voltage drooping less despite the GSII's battery being smaller. It's next to impossible for the radio to be consuming much less power, so that means significant power consumption improvements must be occurring in the rest of the system - i.e. Cell Standby should have a LARGER percentage of the power pie, not smaller.
