Speaking of battery life....everytime I hit task killer it's always killing 17-20 apps... even when I'm not really doing anything what is the deal with that? How do I get this thing to stop running so much **** I don't even need...
[LG Revolution] xcbxcbx:
I have also not been too thrilled with the battery life on the Revolution. It probably doesn't help that in my house the 4G is borderline and drops in and out constantly. I found a $30 extended battery on Amazon, so I'll give that a shot.

But the real reason that I'm posting is because I've been trying to "thank" thecubed ever since I got the phone. I haven't been able to figure out how and I finally found a post that said that you have to not only register, but also post something yourself before the thank button will show up.
[LG Revolution] kphenix:
Get an extended battery

there are extended batteries out there that are rated at 3000mah....this would give you a lot more talk time and standby time. Try one:) Good luck!
[LG Revolution] thermal_tim:
Are you rooted? If so, you can use Titanium Backup to freeze apps. Also, within Android, there are tons of triggers and events. For instance, when you start your phone, these apps open, when you connect to wifi, these apps open. Within TB, you can freeze a lot of the crap. Also, there is a program called Autostarts I really like a lot. Not well known, but great none the less. It will show you all the triggers and events. You can disable them there too. Do some reading and know what your are disabling, but why would you want Slacker to load every time connection status changes, right? Good luck, and if you need more help our want a detailed walkthrough, I can help you out with that.
[LG Revolution] Someguy1027:
Do a Google search for "Android Task Killers" and you'll find all kinds of articles explaining how these apps actually make the Android OS use more battery. There is a good one from LifeHacker that explains it in depth.

So if you're running a task killer, stop... The constant killing and restarting of apps will use more cpu cycles and drain your battery more. Android doesn't use any battery to hold an app in memory. They will launch faster, and use less CPU (which is what drains battery) if they are already in memory than if they are not. You're better off to have your memory full. I killed ATK a couple months ago after reading several posts by Cyanogen, and I not only got better battery life but also increased stability.

Second thing is try Juice Defender. I installed the Ultimate version of it and spent about an hour getting it all configured and my battery went from 100% at 8:00am and 20% at 6pm to 100% at 8:00am and 70% at 6pm with regular email checking a little web surfing, and a couple of short phone calls. I was pleasantly surprised with how well JD works.

De-crapified rom helps too. Thanks TheCubed!
[Acer Iconia A500] msullivan:
Hey there you sexy people. I'm looking at buying a tablet, but if I'm going to purchase a tablet it *must* support Netflix streaming; this is my most desired feature. My second most desired feature is a full-size USB port, so woohoo for the Iconia!

When the unofficial (hacked) APKs came out I know people had some luck with it working on the device. My question is, does it still work, or has Netflix killed it with a server-side update?

I'm specifically looking for answers from people who have recently tried it within the last few days (or are able to try it right now).

If anyone cares to add to the discussion aside from Netflix, feel free to tell me what made you happy or angry about the A500. I know the Android 3.1 release being pushed back over and over is a big one. I'd like to hear if you are glad with your choice in tablet.

Thank you all!
[Acer Iconia A500] Hogmeister:
even the hacked apk's never worked. They were mislabeled as working on that thread. i've been trying just about every hour of every day to get the market version as well as every release thats been put up on the internet along w/ build.prop modifying to get this thing rocking netflix... but alas it still isn't working.

aaaanyway, thats not to say it wont work anytime soon but the only tablet it works awesome on to my knowledge is the ipad, and i'm not counting 7" tablets because i just dont care enough about them to look into them.

and to dive deeper into what you posted about the only real gripe i have for this a500 is that its heavy, you get used to it after a while but at first its crazy heavy. Partly the size has to do w/ the usb port i'm sure, making it thicker which is unfortunate but the weight... i have no idea where its coming from after playing around w/ the galaxy tab for a bit.

good times, hope you find a tablet that works for you.
[Acer Iconia A500] tkirton:
From my understanding regarding the Netflix app (this is compiled from reading many threads on the subject):

Tablets based on Android 2.3.3 seems to work fine.

Tablets based on Android 2.3.4 is a hit or miss proposition, mostly miss. The ones that don't work either have no playback or playback is at a faster speed ("the chipmunk effect" as some call it).

Tablets based on Android launches, but doesn't playback at all (at least up to 3.0.1...don't know about 3.1, will have to read the threads again). Usually says the device is unsupported.
[Acer Iconia A500] msullivan:
I was unaware of both of these things; thank you for your input, gentlemen!
[Acer Iconia A500] entropy.of.avarice:
i wish

In Honeycomb 3.0 Netflix does not even show up in the market on the a500 - none of the modified versions out there seem to work. Tried a million of them.

After flashing the unofficial advance leak of 3.1 for the Iconica - Netflix does show in market, everything works except actually watching anything - bombs out with a 12001 : cannot connect to server.

I would guess support will be added soon - perhaps around the time 3.1 becomes official.
[EVO 4G Q&A, Help & Troubleshooting] effluent:
I'm on CM 7.0.3.1, SavagedZen 2.2.1 CFS HAVS kernel. Haven't made any sort of changes in awhile. My phone is laggy to the point of almost being unusable. CPU load is staying at 100%. Not an expert on finding out what's causing it...but battery use has cell standby at the top at 23%. Supposed to be a question here..so, what's causing this? How do I fix it? Let me know of any other info needed to diagnose. Thanks.
[EVO 4G Q&A, Help & Troubleshooting] Unknownforce:
install terminal emulator, open it and do "top -n 5 -m 5" (press enter)

It will spam some things across the screen a few times, with %ages that indicate where the CPU usage is going.

take a screenshot of that if you can or post what you see towards the top of the list.

There's probably some better GUI apps that can display it a little more friendly, but that's the "dirty" way to see where the biggest CPU hog is.

When I go to enter in a number to dial, if I pause for more than what seems like a second before pressing the 'Call' button, it clears the manual entry. A couple of times now, I've called the last number from the call history because I didn't realize the number I entered was gone.

Any way of increasing the time limit?

Patriot 16gb class 10.

Have had zero problems since last friday.

Sitting here at work and i notice out of the corner of my eye that it restarts itself randomly. I leave it alone to finish up some other work and i notice my backround has changed(from black). Go into gallery....Every photo i have taken since friday(about 60) is now gone. Nothing else. Just the pictures taken with the HTC camera app. Vignette pictures are still there....

I searched around but havent found anyone else that had these issues. Curious though.
[HTC EVO 3D] takmsdsm:
2 things...

1. Language man. No need to curse.

2. Patriot is known for having substandard memory products. Your problem likely exists because of the card, not the phone.
[HTC EVO 3D] CheesyNutz:
nope mines running fine
[HTC EVO 3D] munsterrr:
1. Sorry for the language. There were alot of good pictures this weekend from a Brazilian party(could imagine all the 3d goodness from that) and others. I was pissy to say the least lol.

2. Never heard of it before. I had one in my 4G for about 5 months before it was stolen and i never once had a problem. Win some loose some i guess.

Running "TheRealSync" app now that automatically syncs to my dropbox once a day. I was hoping lookout would copy the .mpo extension but it only does picture extensions.
[HTC EVO 3D] Kilmar:
Patriot is ok but their build quality ain't Sandisk. I've had Patriots break on me, especially their SDHC cards. However, this sounds more like it's a China made fake microSD. By chance did you buy it from eBay?

I have had my Arc since it first came out in the UK but have noticed on occasions of late that it seems to have developed a lag, especially on things like accessing the gallery & messaging. Has anyone else noted this?
[Xperia Arc Q&A, Help & Troubleshooting] Lord Takyon:
Nope. However I do use a cache cleaner every few weeks.
[Xperia Arc Q&A, Help & Troubleshooting] pngface:
Yup, after about 2 weeks mine started to lag every once in a while. I just assumed it was because of some faulty app. So I did a clean install, and 2 weeks later it was the same again. (didn't install too many apps this time)

No lag at all here, 2 months in.
[Xperia Arc Q&A, Help & Troubleshooting] Gpsboy:
Had the Arc (UK) about 2 months and in the last two weeks things have really started to lag. Have had to resort to rebooting and cleaning the cache regularly but it only takes a day to start lagging again. Wondering whether there is a CPU/ memory hog there in my app suite or a widget but haven't been able to identify anything yet. Once the phone goes below 40-50MB free it is all over and I have to reboot.
[Xperia Arc Q&A, Help & Troubleshooting] jatt101:
This may sound weird but my phone lags during the day and it runs super fast at night lol

After update on Android 2.3.3 i don't hve any lag. Before that I had lag but nothing to worry about. I think it was Android 2.3.2 that cousses lag.
[Xperia Arc Q&A, Help & Troubleshooting] aqus:
Same here after about 1 to 2 days the phone memory goes to about 25MB and is practically not useable and need to reboot. I am on 2.3.3
[Xperia Arc Q&A, Help & Troubleshooting] Super Chimp:
I went through my apps & by trial & error ended up removing a particular app & that seems to have sped things up a bit. Also downloaded a history cleaner & used that & that has improved things a bit as well. But in certain areas it definitely still seems to lag. Have to wonder now if it is something to do with the Arc's hardware?
[Xperia Arc Q&A, Help & Troubleshooting] majik8ball:
ok guys after using SeePU+++ i think i found the process that uses the most cpu power and lags down our Arc is "ndroid.process.acore"

not sure what it does but i believe it is the culprit for random slow downs and lag on our phone...

does anyone know what it does? can anyone confirm my findings?

P.s. I am on global generic 2.3.3 firmwre 145

One of the major causes of lag on the HTC hero was having too many text messages stored on the phone. Ever since then i tend to not let the numbers build up too much, and i havent noticed any lag problems on the arc (maybe it's a general android problem).

[Galaxy S II General] jvc+-2009:
I am disappointed with the GPS operation! When I drive eg 50 km/h (cruiser on),

Samsung shows the actual speed of 42-52 km/h!!! Somehow, the GPS jump vaguely. Normally, the GPS device (TomTom etc) shows a steady n.46km/h!

Possibly a bug? I tried for the second Galaxy S2 and the same problem!
[Galaxy S II General] kva:
GPS speed is inaccurate

The same is on my device.

When I drive about 95km/h GPS shows me 94 OR 97km/h. There is no 95 or 96 value at all !

Also it seems that speed is shown only by 3-4km/h steps. It means 3, 7, 10 e.t.c. My previous devices shows me almost accurate speed. Is there any chances to solve the problem ?
[Galaxy S II General] tjtj4444:
Yes, I've investigated this issue a while ago, the speed is rounded to integer steps of 1 m/s (= 3.6 km/h), that is why you see these strange jumps in speed.

The very good news is that this is fixed in KF3 firmware :)

(well, I jumped from KE2, so somewhere in between at least).
[Galaxy S II General] Isadora:
Erm, I assume you are aware that car speedos are not 100% accurate and over-read by a couple of km/h (because by law they cannot under-read, manufacturers play it safe...) and since you're rarely actually doing a constant speed, the gps tends to play catch-up.
[Galaxy S II General] tjtj4444:
Yes I know that GPS speed isn't exact and that car speedos are even more inexact but it is much better now when Samsung stopped casting a float to an integer before sending the speed to the applications...

So we are talking about an actual bug in Samsungs firmware, I haven't heard about any KE2 phone without this issue. It is very easy to check by logging with my tracks in a car and check an excel export, it only shows speed in steps of 1 m/s and this happens in all applications.

But it is fixed in KF3 so this is no big deal anymore, and maybe fixed in KE7 as well, that could explain why there aren't much discussion about it at XDA.
[Galaxy S II General] Isadora:
One less variable in the equation is always good :)
[Galaxy S II General] BennyT83:
i dont think its fixed in KE7 cos thats what im running and the GPS is all over the shop
[Galaxy S II General] tjtj4444:
This thread concerns a very specific speed problem where the speed reported from the GPS driver jumps in steps of 3.6 km/h.

It is not about a positioning problem.
[Galaxy S II General] alexbrickwedde:
Hi,

is it in the Kernel? Or a module/software in the ROM?

...Alex
[Galaxy S II General] HereAsWell:
For me, the GPS accuracy was not improved with KF3 (coming from KE2).

I checked it with the app "GPS Test" and it took ages until I get a accuracy of 10m ... but it was still not really stable and was "jumping" from time to time to 20 or more meters.

I use my device for sports tracking and this bad accuracy was a "no go".

But I found a solution that works for me pretty well.

I installed the app "Faster Fix" from the Market (requires root). To my surprise Samsung has set the NTP server for A-GPS the one located in the US. For me as European with is causing trouble because of the latency accessing this server from here. I used "Faster Fix" to set the European Server. Cleaned the APGS data using "GPS Test" and since that moment GPS is working great. I have a fix in 2-5 seconds and the accuracy is by 5m (sometimes even better).

Regards from Germany
[Galaxy S II General] tjtj4444:
The thread title is a bit misleading, this thread concerns a very specific bug in speed reporting from the GPS.

But your solution looks interesting for other types of GPS problems, so I'm not blaming you for sharing this :)

But it could be useful to post your solution in a thread that more concerns general GPS stability as well, but I haven't seen any such thread active in a few days, so I guess most SGS2 users doesn't have any GPS problems :)
[Galaxy S II General] bambollero:
Gonna try this later, but my HTC Legend also has a US NTP server and I have never had any problems with it.

Other than that, I confirm also that my SGS2 is inaccurate in both speed reporting and positioning (tried KE7 & KF3).
[Epic 4G Q&A, Help & Troubleshooting] Xiutehcuhtli:
So according to the Quadrant score, it appears that after turning Journaling on (using SRF 1.2) my phones performance slowed by 8-10%. I realize that this is not a huge change there is something special about pummeling all other devices listed by as big of a margin as possible.

My question is, for those that have journaling off (which I currently do not) how do you deal with the potential for errors and force closes? I have had VERY bad luck with it off thus far.
[Epic 4G Q&A, Help & Troubleshooting] duce102:
Make sure you have an extended battery then super glue the battery and the case to the phone. =]
[Epic 4G Q&A, Help & Troubleshooting] chris41g:
I only journal my data partition, thats where the important data is.. system is RO 99% of the time, so a crash wont effect it... and cache.. who cares..

[Epic 4G Q&A, Help & Troubleshooting] Dulanic:
I tried without journaling many times and in the long run it always went bad. It just isn't worth it in the long run imo. But that's just my opinion.
[Epic 4G Q&A, Help & Troubleshooting] JohnCorleone:

[Epic 4G Q&A, Help & Troubleshooting] duce102:
Yayyyy!!!! CWM Flashable?
[Epic 4G Q&A, Help & Troubleshooting] mkasick:
Alternatively, the journal isn't used if a file system is mounted read-only, so leaving the journal on for /system shouldn't have any performance penalty.
[Epic 4G Q&A, Help & Troubleshooting] JohnCorleone:
...turning on my laptop just to thank you chris41g. If you started a thread for this I think people may jump all over it with all of the journal debating that has gone on around here about performance/speed vs. stability.
[Epic 4G Q&A, Help & Troubleshooting] chris41g:
Thanks, thats good to know.. is that EXT4 specific, or all journaling FS?
[Epic 4G Q&A, Help & Troubleshooting] JohnCorleone:
Wait, I am confused a bit. So does this mean that your zip is going to give the stability without the performance loss? Or is mkasick saying that you can add journal somewhere else without a peformance hit?
[Epic 4G Q&A, Help & Troubleshooting] chris41g:
what hes saying is that on a read only filesystem (/system), that even if journaling is on its not used...

i did some more research, and there is a benefit (in my eyes) to disabling the journal on RO FS anyway.. after a crash, a RO mounted FS will still write its journal, meaning its writing to a RO filesystem...

There may be more underlying things going on as well, but Ive used this config for quite sometime... its kind of a best of both worlds thing.

I also move my dalvik-cache to /cache, so not journaling cache probably impacts performance even more...
[Epic 4G Q&A, Help & Troubleshooting] JohnCorleone:
Thanks for the clarification...and the zip! I am definately going to give this configuration a shot after work.
[Epic 4G Q&A, Help & Troubleshooting] mkasick:
Well, it's every journaled file system I'm aware of.

By definition, there's no mutations going on in a file system that's mounted read-only, not even atime updates. Since there's no mutations, there's no transactions written to the journal. Beyond that, since the journal itself is part of the file system, it can't be written/modified either since it's read-only.

If there's a crash/power-loss event when /system is mounted read-only, it's still marked as being in a clean state since there wasn't (and couldn't have been) any outstanding transactions. So there shouldn't be any journal replay.

In my experience, if you attempt to mount a marked-dirty file system read-only after a crash where it was previously mounted read-write, the mount attempt fails. You actually have to mount it read-write to allow the journal replay to proceed, then you can remount read-only. My experience with this is with jfs, so ext4 could be different, but I think this behavior is common across Linux.

But finally, if /system was previously mounted read-write and a crash happened, you want the journal replay since otherwise it's quite probable that the file system is in an inconsistent state. Especially given that, with /system, it's only mounted read-write when folks are actively doing something with with it.
[Epic 4G Q&A, Help & Troubleshooting] JohnCorleone:
Wow mkasick, you just made me realize how little I know about what's really going on. So are you using a journal on ROM or some variant of journal on?
[Epic 4G Q&A, Help & Troubleshooting] mkasick:
Yes, but by virtue of still running rfs. Actually, I've been running the same file system since DG27, just applying official updates as they come out, rerooting, and modifying the kernel & framework as I find necessary. Ironcially, I'm not really into ROMs.

There's nothing wrong with using ext4. There's definitely lag in rfs, although personally it's not been annoying enough for me to bother switching. Disabling the /data journal in ext4 will result in better performance, although I can't say to what degree one would perceive it. Of course, it also greatly increases the risk of file system inconsistencies in the event of a crash or power loss.

Personally, if I were running ext4, I don't think the risk of damage to /data isn't worth whatever performance benefit there might be to running without the journal, so I would run with the journal on. Since /system is read-only most of the time, it doesn't matter for performance purposes.

By default, /cache sees so little activity that I doubt there's much if any performance benefit to disabling the journal there. There's no harm to running with the journal disabled if you're OK with reformatting it on power-loss. But I question the benefit too.

Also, to my knowledge Epic folks are the only ones still playing around with ext4 no journal. The only other Samsung device ROMs that disable the journal is for /cache on the I9000 (and other GSM models?), which is done only because it's a very small (~30 MB) parition and the space used by the journal is needed to allow larger Market downloads, not for any performance benefit. Our /cache is 168 MB, so we don't suffer from that problem.

To be frank, I think it's irresponsible to release ROMs that disable the ext4 journal. If folks really want to do it, providing that functionality in an update.zip is appropriate. However, most folks won't notice or understand the difference, and I'd err on the size of reliability than potential performance benefit. But it's not my position to complain as I'm not really into ROMs.
