Does anyone already install the newly released CM 7.1.0.1 ? in my HTC Wildfire the incoming call is somewhat lagging around 1 sec. I dont know whether is it becoz of my mobile or heavy graphics in CM7. anyone find solution for this lagging problem ?
It's actually far better than in previous versions, which used to lag by about 4-6 seconds. A few things which have helped:
- Keep min CPU frequency at 352MHz
- Keep CPU goverenor at Interactive / Ondemand
- MOST IMPORTANT (From my testings anyway) - If you don't use a cover, this problem doesn't arise (Lag is near zero). The cover blocks the proximity sensor, hence, the screen is turned off initially, and when the cover is removed, it will definitely take some time for the screen to turn on, which gives rise to the lag.
That's useful info. I'll try it.
Hey guys, I was getting terrible battery life when the phone is idle. I looked into it to see what was going on. First off, I am on the stock rooted deodex'd ROM that scrosler posted. The biggest problem was an app I installed called Light Flow Lite, it controls your LED. It had over 6 hours of wakelock today. Removed it, not worth it at all.
The second thing I found that was interesting was after that, the phone STILL wasn't hitting deep sleep. I poked around in BetterBatteryStats and didn't find anything in there that would explain that. I then ran a "top" (in terminal or adb shell, type top -m 5 -t). Everything looked normal, nothing crazy. But I turned the screen off and let it run for a few seconds. I got a massive spike in CPU (anywhere from 15-35%) for system_server with the thread "WindowManagerPo" (which is likely short for WindowManagerPolicy).
I did some searching and it turns out that there is a bug with auto rotation that causes this. Essentially, the sensors don't stop looking for orientation change when the screen is off. I found reports of this in the Nexus S forums, GS3 forums, etc. This leads me to believe it is a Samsung kernel issue, since that's the least common denominator when it comes to the phones that had this issue. If you don't use auto rotation, you probably aren't encountering this issue (but keep reading for some good info below!) But I use auto rotation, how can I fix this?
Download an app called Auto Rotate Auto Lock. This app will turn off auto rotation when your screen turns off and enable it back when you turn the screen back on. This looks like this should really help to combat this bug and it handy for people like me who like auto rotation but don't want to have battery life suffer from something as stupid as this. I have verified that my phone now does enter Deep Sleep easily, and it hadn't hit that all day!
I also recommend an app called CPU Spy Plus (XDA thread). This app shows some very valuable information about your processor. You never want to see "Deep Sleep" under Unused CPU States as this means your phone isn't sleeping and is wasting battery!
It would also be good to download BetterBatteryStats (XDA Thread). This will help you nail down battery drain that you won't see in the stock Battery graph found in Settings. Things or importance are Partial Wakelocks and Alarms.
Monitoring these apps can really help you to increase your battery life on your phone. If anyone else is having bad battery life when idle, please try this out. I'm sure this will help you Feel free to ask questions, I will try to answer them as best as I can!
I have autorotation turned on but not the face orientation sensing. I haven't noticed a significant battery loss, at 19 hours with 10 left according to battery spy, but I'll give this a try and see if it increases it any.
i'll give it a shot. i was wondering how at work it would drain 2-4% an hour but at home with a crappy signal i'd only lose 6% all night.
at work it's in my pocket and at home it's stationary.

I have noticed Google Talk drains batteries when your signed in. By default your phone will sign in. If you don't use TALK, sign-out of the app and you will see increased battery life. Your wont ping the internet as much which saves batteries.
Thanks viperboy I took your suggestion and so far it seems to be helping.
I haven't tried that app yet, however I have definitely noticed an improvement in battery life by disabling auto rotation. Thanks for the info.
THIS NOTE 2 IS SENT FROM A GALAXY WHERE SAMSUNG SPRINTS TO THE TOP, AND JELLY BEANS EAT APPLES!!!!
after a bit of troubleshooting i found that battery monitor widget pro was the cause of my drain. after removing it i went from 2 to 3% an hour to 3% overnight. this really sucks as i love the info bmw colleects. this is the only device i have that suffers drain from the app.
Thanks for the info. I have been losing % 15 battery every night while I'm asleep and was wondering why

Thanks for the suggestions. I have heard so much about the great battery life, but that has not been my experience. I had a Note 1 and I had no problems. With Note 2, the battery drains to about 1/4 after about 7 hours with limited use. I have turned off auto rotation, lowered the screen brightness, changed auto check settings for email, and don't see much difference. In addition, it seems a shame that I should have to figure out ways to use fewer functions to make battery last for phone calls, since I never had to do that before. Any ideas?
Thank you for this info. I consistently get a full days charge of of my phone but was pretty clueless when it came to what was draining my battery. I've used the rotation lock app and will report my results to see if I get even more remaining battery each day.

As viperboy mentioned, BetterBatteryStats is your friend. It really will help you figure out why your phone isn't sleeping like it should. It definitely takes some time to monitor and figure out what the readings mean to help point you to the apps or settings that're affecting your battery, but well worth it. I also like having a better understanding of how things work on my phone.
i did a double check on battery monitor widget pro and it started draining my phone again. as soon as i uninstalled it everything was fine again. this is with both cleanrom and blazer. i'll just wait til official support comes and try it again.

Have you tried the Perseus kernel? I hear the battery life is improved with it. So may be it doesn't have the rotate issue.
I've been using cpu sleeper and I easily get about 30 hours. Looks like the new apk fixed quad core. So when the phone is off it only uses one core and shuts down the other three and lights them back up when you need them.

That app is unnecessary. Pegasusq governor already does that by default. Goes to 1 core and 200mhz when screen off, at least that's how my Note 10.1 was. I assume it is the same here since the International GS3, GN 10.1, and GNII basically share the same kernel with a few minor differences.
I think I may try the perseus kernel today to see if it improves battery.. I haven't heard it does.. I just been seeing people do that benchmark stuff with it

Interesting... I have a script that reports on CPU freq and, when plugged into USB (maybe the wall charger too, didn't check), it appears that the kernel runs cpu0 and cpu3 all the time, even when screen off. With the phone unplugged, it went to using only cpu0 but didn't cap the freq. It was spending a good amount of time at the higher frequencies even though I had nothing running.

I installed the app to turn the rotation off when the screen is off so far everything good but when I get a call this goes crazy because the screen goes while in call. I know this because I have an smartwatch which it has a notification app and every message that the phone has my watch vibrates with that message and I had a call few minutes ago my watch started vibrating non stop until I hang up.

Hello guys, I just updated my note to the latest DMA6 stock rom as I saw a lot of good reviews regarding battery life.
However, I was just stdading at my desk and as soon as the phone booted up after the flash, I noticed some massive tearing which annoys me as hell. For those who don't know what it is, it feels like the screen refresh rate has been drastically decreased. In order to detect it on most note 2 you can follow these steps (well most of them are working this way, because I have tested this with some other notes):
-- just lower your brightness bellow 30% go into a dark room and keep looking at a fixed point while moving the phone up and down in front of your face, this while having a bright image on it. If you see a flickering image you're a victim too:S
Another way to notice this is looking at your screen trough another (phone) camera...you will notice the old CRT effect of some horizontal lines scrolling up
I had this on my 4.1.1 as well but only till the brightness was at 40%. On 4.1.2 it goes all the way till 80%.
Being pissed to the max, I flashed my 4.1.1 backup and guess what?! Tearing gone at 40%, thus it seems to be an issue with the latest kernel.
For those wondering...yes I have disabled the screen power saving option in the power saving menu.
Has anyone noticed this? Does anyone knows how to fix it?
Cheers
If you mean to say lag then. Factory reset.
Sent from my GT-N7100 using xda app-developers app
I never recall mentioning lag whereas you probably refer as to graphic rendering delay. The phone's interface is acting as it should be, it is as smooth as expected, no issues there.
Perhaps this video will describe better what I mean http://www.youtube.com/watch?v=vL_6H-0GD3Q You can see the screen flickering very clear. This is why I mentioned that you can test this in a dark room by moving the phone reproducing the old crt effect
My question is why does the flickering/tearing dissapear on some roms at 40% and on other above 80%?

Getting vertical lines on smt700 non rooted after over the air update (U.S)
After update I did a factory reset installed apps One by one and I started to notice a flicker of VERTICAL lines appearing at start of boot and also when batter is low it will freez slightly and do the vertical line thing before freezing a little then shutting off..
this only also with games...
Thanks a lot..

My sister noticed an occasional black screen flash after updating her Tab S 10.5 to Lollipop. I have the same model upgraded to Lollipop and have never experienced this issue but twice, once on KitKat and once with Lollipop I saw part of the screen look scrambled (like an old set tuned to a channel that WA not in range), for a second after hitting the home key.

Green flicker
Smt700 wifi screen flashes green and gets vertical lines....
Sometimes when the screen does this flickering it restarts...

My 10.5" T800 has been on for over 200 days and has never been turned off or rebooted since i got it, no problems at all with flickering, but the older you get the less sensitive you get, I am not a gamer so my tablet is not stressed.
If you are having problems get your tablet repaired or replaced.
John.
I ve the same issue after upgrading to lollipop, I cant find the solution
Still flickering
try everything to solve this flickering with vertical line issue.
Nothing worked..
Factory reset, disable hardware overlays and limit performance ultimately won't fix this issue...
I have the same issue.
Downgrading does not solve the problem
I have seen that it happens when battery is lower than 50%.
To mitigate the problem I have set seen brightness to 30% fixed and also losing mobile segnala makes the screen flicker or the tablet to reboot
When you rotate the tablet do the vertical lines rotate as well.
John.
All problems started only after lollipop update.well most of us are getting them,,random reboots,green flickering lines,grey bars etc,,
But the only available solution for flickering Is turning the power saving mode on which is what I have done
iam facing this issue with my t705
its not the lollipop fault
its an hardware problem, the battery connector socket
This happened to me before and after the lollipop update. Someone suggested to use power saving mode to restrict CPU usage. It seems as if the tablet goes crazy whenever theres a high cpu load involved.
I have the same problem after update to lolipop. Most often occurs when there is a lot of notifications and low battery.
In my opinion is a software problem, what do you think ?
edit:
8% battery, lot of vertical lines during using notifications center, tablet reboots - this never happened before (on 4.4).
[SOLVED]
Fixed screen flickering issue !!
did this by governing the frequency to not pass more than 1.6 ghz...
Rooting then installing overclock widget and setting frequency to not pass 1.6ghz. Max..
From what I know about chips ''they are not all baked alike'' the same chip could come out with lower stable frequencies ..
I hope this helps someone for it has 100% solved the screen flickering problem for my smt700...
Thanks...

My relative has complained of an odd flicker (screen goes briefly black) after updating to Lollipop. Usually happens while moving from an app to the home screen. I sent them instructions based on that article so they can test if it fixes their issue. I'll post the results but likely after a few days to make sure it actually works. Oddly enough I have an identical model SM-T800 on Lollipop and do not have the issue that they find so annoying.
Thanks for posting the article.

I've seen it on mine since Lollipop came along. In my case I get the screen with snow - like a TV tuned to a channel with no signal - . It's happened when the screen was timed out and then awakened. I've not been bothered by it more than about 5 or 6 times so I've just not bothered with doing anything about it.

Service center in Poland (CCS) replaced screen and repaired motherboard. It seems to be fixed.
I thought it was a lollipop issue, but having followed the advice to force GPU screen rendering through developer options, I found the problem did not go away. Thus, it must be a hardware issue.

Hello,
Did you try to set the default CPU frequency to 1.6 ghz... maybe even try to govern it down to 1.4ghz.
For my WiFi smt700 simply underclocking the cpu completely fixed the issue...
The issue is due to either your tab cpu wasn't from a set baked that could handle Higher work loads or quick raises in frequency like from sleep or switching between apps.. forcing GPU rendering take away resources from cpu and forces the GPU to do the work.. Hopefully an official kernel update could help with this in the future...
But for now under clocking the cpu or force GPU rendering or powersave mode all appear to help resolve the screen flickering issue and the only constant that I can determine is that these fixes all involve taking away workload from the cpu...
UNDER CLOCK FOR NOW !!
Thanks... (hope underclocking helps some members here)

That's interesting. Unfortunately, my device is not rooted yet and I don't plan to do that in the near future. So while I can use powersaving, I can't underclock. If there is a problem with the quality of the CPU, then IMO Samsung owes me a fully working device. I mean, they sold the device with the idea it was able to run at correct speeds.
