Hi Guys...
I've Already Uncapped My X10i (2.3.3) To 54FPS, But It Seems A Little Bit Eye-UNFriendly In Scrolling Or Some Other Stuffs...
I Wanted To Know Whether There Is a Way Back To Factory 30FPS or Not?
If There Is a Flashable Package Via Recovery, I would Be Thankful To Provide Me So...
Thank You In Advance...

I just did the fps uncap thing and youre right its fast(awesome) but if its uncomfortable for you, you should get try doing the 34fps uncap, it will be slower i think
Just search for in the forums "fps uncap" there will be a topic about someone wanting to go back to 34fps, download from there and flash thru xrecovery

I think 34FPS is still a Modded cap, since the original is only 30FPS, I need the original because I want to get rid of battery drain, too...
but anyway, thank you dude, every word you type makes me owe you one

Well, you got me in a boring night so i started looking around but couldnt find the original.
You gotta keep looking but if you.dont find anything, back your apps with titanium and flash doomlord's pre rooted image, i know it sucks to do a fresh start but the battery is worth it.
This is just as a last resort though

lol why would you possibly want to do this?
there is no battery drain imo, and it is a million times better/smoother.

r u sure there isn't ant battery drain?!!! my battery sucks after flashing this mod, although it performed pretty decent before flashing 54FPS...
but as u know, there is no way to precisely monitor the effect of a single mod like this on the battery life...
so, I DO put my trust in you and assume that there is no battery drain

Why would anybody wants to un-uncap the FPS? That has nothing to do with battery drainage.. Also I don't get how an unsmooth scroll animation does not hurt but smooth one does?

First of all, as I said before, anything we say about battery drain is just an estimation, there is no way to precisely calculate how much battery is used more than before applying such mod.. Then I said I just FEEL that drain, when people like you, and other friends say that it doesn't, so I put trust in you
and about un-uncap, what you say is basically true, higher fps gives better smoothness of overal performance, but that happens only if GPU is capable of doin so, a weak Adreno 200 is not somthing brilliant at that render, especially running at these goddamn kernels of SE. also Vertical Sync seems to be disabled in order to reach that 54fps, which gives the screen a little bit annoying refresh rate, THIS is the ONLY thing which bothers me, and we are still in the same boat that it gives a UNBELIEVABLE smoothness to the device
now, if you are sure about battery drain, then I will keep the current setting, since as you said, it is really nice and smooth
thank you bro, thanks for everything

I think you are uncomfortable with the tearing that occurs occasionally, i think that we should wait for an fps cap at 54fps so it doesn't tear as much as 54fps uncap.

YESSSSSSSSSS, that's the point, I think you're completely right, because constantly changing fps is the thing which hurts the eyes, if sb (for sure Z!!! ) could find a way to cap it to 54fps, it would be great...
Disabled Vertical Sync is annoying
Whether rom&kernel I used I always have lag on phone while the graphic chip is being used, for example in YouTube application when the video started it becomes too laggy and when I paused or stopped it becomes normal, and when i opened a game when i turn off the screen the crt animation becomes too laggy, too, and in bencmarkes my 3d points lower than other Evos, what do you think the problem is and how to solve it?

Seems as if you've tried many different troubleshooting options and still are experiecing this issue. I haven't seen many reports of it and it does seem very odd.
If this option is possible, I would load 100% stock software back on the device and see how it operates. If it is still really slow, there might simply be something internally wrong with the hardware and I would look into returning/exchanging.
I'm on 100% stock and have been since June '11. I've never seen any lag during the screen off CRT animation. Lag at that point seems awfully odd unless you're in the middle of some type of graphics/cpu intensive program .. even then .. I would have a hard time seeing consistent lag at that point to be legitmate behavior.
Hope that helps!

Thanks for your answer, I've tried stock Europe RUU and its the same and i don't have guarantee to exchange what to do now?
And I remember, I wasn't having these issues before, after trying too much ROM and kernel it happened, I always wipe everything before installing a rom, but do we have a full cleaner, kernel cleaner eg.?

Using the real RUU will restore all stock partitions with the stock images.
I suppose, if you wanted to go the extra mile, boot into the custom recovery and format each partition, then run the RUU, but don't think I've ever heard of people doing that before an RUU so not positive if there would be any adverse side effects.
If you're on the stock RUU and experiecing issues, it would seem hardware related in my opinion as I'm on stock and have rarely seen those issues.
The only other thought which comes to mind is sometimes when people overclock they perhaps allow the device to become "too hot" and I suppose this could cause some minor but permanent damage.
Another thought, I know in my EVO last year, had a bright spot appear on the screen from "over heating" although I never overclocked, it was essentially a design flaw many experienced.
The only other suggestions I can think of would be to back to stock, knowing you've cleared all custom software off and perhaps load a basic kernel which supports voltage/speed adjustments and see if tweaking any of those help with the graphics lag.
Good luck!

Great point, I actually had forgot about the sdcard. Some bookmarks are stored on the sdcard!
I wouldn't think any important settings are stored on the sdcard, but if you wanted to be even more thorough, you could backup all your sdcard contents to your desktop and format your sdcard.
That should ensure no settings remain after running the RUU.
So many details to remember! Hope that helps!

Ooohh yeah I took a point! I've tried other browsers, and now I'm using dolphin, and while I'm using maxthon browser I played 1080p video and I've turned off and on screen without any lag! But if I use YouTube application, or play video from the phone with its own player or es video player it lags, and in games lag has gone too, its getting interesting every time
Aha I've got one more point too! I used MX player and when in hardware mod the lag happens, but if i choose software mod, the lag goes away!
Many have complained about issues with the kernel in ICS. On any build, it is vital that you not use setcpu or any other cpu scaling app. Don't change the max/min freq, don't change the governer, nothing. Perflock will constantly reset any changes and cause the cpu to run at either full throttle or full min - no in between. Until we get kernel source and custom kernels, this will always be the case. It's something HTC does.
Many cpu monitor apps will do the same. The link in my sig has more info, and a link to a cpu monitor app that is safe to use with our kernel.
Actually when I was on the second ics leak, and setcpu worked fine. I know this because I benchmarked before and after setting frequencies
Sent from my ADR6425LVW using XDA
benchmarking doesn't mean it wasn't running at full tilt when you didn't need it to. unless your kernel magically doesn't include perflock, it was.
also, there are some combinations of setcpu and monitoring that will work. at one point if i used setcpu, cpu monitor, and one other which i forget now, it would work, kind of. definitely not recommended.
Thats why I deaded mine. Phone was constantly overheating
Sent from my ADR6425LVW using xda premium
since i stop fighting with the kernel i've had nothing but great battery life and performance since the first ICS leak.
tsp, what i don't understand is why something like system panel, which shows you scaling (but doesn't let you change it) showed the proper correct scaling between 384 and 1512 and hardly EVER hit full throttle on GB, but on ICS, it's always showing full throttle.
then i installed your widget you showed me, and it showed constantly chagning like system panel used to on GB.
any idea why? which one is rgiht??

Agreed. I had set CPU try to disable perflock and limit to 1200mhz on conservative and it ended up being worse battery and slower overall.
You're exactly right I advise everyone I discuss the topic with to make sure and avoid trying to over ride perflock with a CPU management app. It causes a conflict in my opinion which is a huge battery drain and also causes excessive heat due to the process of fighting for its life.

the widget i posted is what you want. it should be scaling up and down, and settling eventually when nothing is really going on. the system panel that you tried clearly affected the perflock in some way. from what i understand, some apps/widgets look at the cpu itself, while others hit up the kernel for status. the ones that hit up the kernel are the issue. i'm not 100% on this, that's just what i've been told. all i know is my experience seems to match this.

Hmm, that's weird, cause I've been using setCPU with ICS on the Rezound for months and it works great! My CPU scales fine and hits all the frequencies its supposed to. The min and max frequencies do change around seemingly randomly, but anyone can see by watching the current frequency display that it is always somewhere in between the range I selected, and always appropriate for the system load.
I've always had CPU Master installed. I just removed it, we'll see how it goes.

The main effect of that change in HC is to burn through the battery faster. You can accomplish that more easily by turning up screen brightness!
HC doesn't manage multiple cores well. Forcing it to be on doesn't mean that HC will assign threads to it.
And if you're running an ICS alpha, you don't need that change. ICS handles multi-cores fine.

Ugghhhh ..... my bad. In my post above, I said HC where I meant GB. My comments above actually apply to GB, so - no.
how much is the battery difference between the regular mode and the dual core always on mode?
drastic from what I remember
Sent from my mopho
yeah it will chew some battery up fast, also runs higher temps, blah blah blah not needed for a daily phone user. if you are modding out to use your phone for something else (heavy into games or some kind of benchmark testing) then it could be beneficial, but not needed for 99% of programs or users.
with the stock settings, you will see the 2nd core kick on when 1st one starts to get up in a higher frequency due to processing load. 2nd is always on in a sense but more as an idle state since it ramps up when needed. turning the 2nd core to "always on" basically keeps it always active for even the smallest of tasks.
I like the engineering behind leaving it stock. stock does use both cores still, lower temps, better battery life, and gets the job done.
After reading the general forum a bit, I stumbled across a post from someone using the Seeder APK [Root required] to help mitigate some of the lag/stutter/UI weirdness some of us are seeing on the G3.
I had never heard of this app before, so I looked into it and found out more here.
I downloaded the APK and turned it all the way up. I enabled all it's options and let it work; and well it did. Specifically I saw a reduction in stutter when flipping to the recent apps screen, and generally improved performance with other UI animations like scrolling. Some are even reporting better performance with how third party keyboards animate and respond, a problem I had run into using Swiftkey.
I cannot explain why this is working and apparently neither can the developer, because the newer versions of Android do not handle the processes this is supposed to address in the same way. Give the thread a read and try it out, so far its made a difference for me and I'm happy with it. :laugh:
I've used seeder for a long time now over 3 different phones and it always seems to do the trick. I have been getting some laggy animations on the G3 (why can't these companies focus on making the experience smooth throughout :/ ) and seeder has seem to reduce the lag the most. I'm surprised how choppy the animations are on the G3 at times because my G2 ran like a dream most the time. I expected more from the G3 though it's still a great phone that imo is much better than the m8 and s5. I mostly assume it's down to the screen res and size and the fact that apps and android itself is becoming more and more resource hungry. I guarantee if you put ASOP 4.0-4.3 on this thing it would fly.
Do we download the latest apk from that forum you are providing?

I have read that, however despite that information I do perceive a difference and no its not a placebo. I understand that the professionals cannot substantiate a change. All that I can suggest is that anyone that has a complaint regarding the G3 and laggy behavior...give this a shot. If it doesn't work, chuck it....if it does great!

People always try to debunk the fact that seeder works but the reviews in the google play store and my eyes have always told me otherwise. When a phone is very clearly lagging and then you install seeder and notice the change right after I don't think we need any experts to tell us our own eyes and mind are deceiving us. Experts have made a living off being wrong about things.

I've tried entropy generators in the past before I knew more about the subject and never saw a difference. This is programming, not magic. We know what Seeder does and we know how android works
The only users of /dev/random are libcrypto (used for cryptographic operations like SSL connections, ssh key generation, and so on), wpa_supplicant/hostapd (to generate WEP/WPA keys while in AP mode), and the libraries that generate random partition IDs when you do an ext2/3/4 format. None of those 3 users are in the path of app execution, so feeding random from urandom does nothing except make random… well… less random
Click to expand...
Click to collapse
I tried the symlink method and could not detect any appreciable change in load averages under otherwise similar usage scenarios. I cannot find evidence of access to the /dev/random file. I cannot find similar wait paths in the kernel code that accesses the entropy pool that is shared by /dev/(random/random). That leaves other kernel locking or blocking mechanisms (spinlocks?) if there really is a responsiveness boost. I haven't seen conclusive evidence either way, I am just trying to understand what would possibly influence responsiveness should this hack prove founded in data.

I'm sorry why no one is mentioning this, but the 'fix' involves running a daemon that writes to /dev/random every second. This daemon should affect the CPU freq governor and make the CPU run at higher clocks than a device without the daemon. This alone would account for the performance increase users claim to be experiencing.
I've played with CPU frequency governors in the past. Perception of lag is affected greatly by this.
The claims about the depleted entropy pool leading to lower performance are not substantiated. I am thinking that there shouldn't be such a huge dependency on /dev/random in Android to cause an appreciable performance difference.

No problem Bob, and I understand where your coming from. Thanks for inserting logical analysis into this discussion, and for sharing what is known and understood about this apk.
Does that mean I will stop using it? No, because it works for me. Do I encourage others to try it? Yes, for the same reason. Do I accept that there are many that wouldn't even glance at this because its not supposed to work?...Yes. No big, I'm not the developer.
Afterthoughts..
From what I can glean I think this is what we may be seeing here - "I've played with CPU frequency governors in the past. Perception of lag is affected greatly by this."
Can we do this currently? I mean change CPU frequencies without an unlocked boot-loader and a custom ROM?
I just wonder how all this is affecting your battery life. Has anyone done any research into how these effect wake time and battery performance? Seems to be the idea is if you keep the cpu a bit active you get better performance? It seems to me that if that is the case then a less aggressive cpu governor would have the same or better effect on reducing lag. At least that is was I perceive after reading about entropy regarding cpu and different platforms. Linux and windows generate random numbers differently.
Turn on developer options.
Look in the options settings.
