Hello,
I'm wondering for quite a time why the camera is so slow.
It can do about EVERYTHING but if you want to make some pictures of a moving thing passing by, you are ALWAYS too late.
The only thing I found that helped a bit was a custom camera app from the market which speeds up the camera a little bit by decreasing the resolution.
Is this due to a slow SD-card?
Navigation maps for example load instantly and doesn't shutter at all.
The question is thus if there is any way to take pictures faster, because my k800i was certainly not slower with taking photo's.
BTW: I'm running RemiX10 rom, Min 122MHZ Max 748MHZ quadrant score 97X
Thanks in advance,
Me2freedom

So I was scrolling through my phones statistics when I noticed that the screen refresh rate was at .1hz which got me a little puzzled seeing as it's supposed to be at 60hz. I was wondering what effect this has on my phone exactly and if there was a way to get it back to 60hz. Also I'm using the gb fps uncap if that helps
This is a stupid answer, but if it works fine, I'm sure it's just a glitch, and it's actually 30-60Hz.
You don't notice .1 Hz do you...would be kind of unusable I think...
Hello android fellas..i am an sgs 2 owner and a log time android user..for the most of android devices the most screen time i could ever get is 5 hours (screen on, not idle..idle means ntn..with uv i can get week++)..
So the question i rise here is, will ice cream sandwitch help our battery effeciency with hw acceleration?i noticed that my phone can do as much as 10 hours+ of video playback, but can only surf the web for around 4-4,5 ...which is amazingly ridiculous..if i let the phone idle , with screen turned on, at all times(there are actually apps to do that) i can get almost 11 hours of screen on time..but if i use my phone to as much as navigate through menus, i am lucky if i get 30% of that time.
That led me to the conclusion that cpu usage for 2d ui elements drawing is at best idiotic, but other than that, its that its not my device(s) problem..its the os that sucks it up..
So, do you believe, that ICS will fix that?is there hope on the horizon?4 hours screen on time/day , just wont cut it for a tought work day for me..
( i would like to close that section by saying that i am a 2 year android user and i know what i need to shut down, when to have on and what so that my batt is at its max effeciency..)
Opinions please? Will our GPUs make us look less embarassing?
Unlikely... partially, because the majority of actions needed by a web browser is unable to utilize the GPU (it's really only usable for compositing and rendering, which occurs surprisingly seldom outside of games: really only while the document loads... of course that's bound to change at some point, but for now, there really isn't much to gain other than more fluid animations), but mostly because it's a bit of an unfair comparison: Video playback today is more or less handled by special-purpose silicon, not what you'd usually call "The GPU".

no, i am aware that java still needs to be rendered in cpu... but i was not only bein referred to in browsing...menu browsing as well..ui navigation should be humongousl benetited am i right?
Accelerated is usually faster and smoother, especially multiple layers benefit greatly from additional acceleration (note however, that Android already uses that in most cases)... it just doesn't really translate to power saving.
Java doesn't really have anything to do with that: it may put a bit of additional load on the CPU, but that's not what's eating your battery, especially since virtually all computation-intensive parts of Android are written in C++. The real problem is that while the GPU is faster in these "burst" situations when there's suddenly a whole lot of layers to render, it's hard to predict those. So the CPU most always run at an acceptable rate... which in the end often means that the accelerated version uses more power since the system isn't able to clock down the CPU nor the GPU.

Damn..The load that cpu took from being less effecient to draw 2d, was my best explaination as to why our batteries suck so much..
It is definately not the phones..As i said earlier if i let the phone screen on, just idling, at, say auto brighness, it can go for 10-11 hours..but if during that time i, as much as navigate at menus, or settings , or whatever ui...BAM..4-5,5 hours maximum..
It HAS to be something wrong with the os..heck i can do 10 hours of .avi playback on a single charge , but i cannot go over 5 for just panning around the app drawer..(and my screen is amoled so it greatly benefits from black background of the drawer)...
If you could shed some light to that, for me i'd love ya even more!
Btw on my second post i meant to type javascript, not java my bad!
I know everyone is excited about overclocking their primes, but has anyone thought about underclocking it? I would love to hear the capabilities of that on battery life. Also, will we be able to use setCPU to control our speeds on the prime?
Already can be done, in a sense on stock prime. JUST KEEP it in powersavings mode. You will get the most/longest battery life out of it. Plus you can still play movies or games in that mode just fine.
NOW IF YOURE rooted, I'd say get System Tuner Pro app. IMO its alot better than set CPU. It does all the same things and alot more. From there you can manually lower the maximum frequency range and there goes underclocking Or you could try out one of system Turner's preset modes. I believe they have a power saving one also.
Really though stock powersavings mode is good enough for long battery life. ITS optimized for everything to still work pretty well or fast. Manually lowering the Max speed too low might cause it too lag really bad or maybe even instability. It would be about finding that sweet spot to where everything still runs good.
ONE THING TO think about though is no matter how much you underclock, the display brightness will be the biggest battery drainer. SO underclocking with Max brightness or something won't make sense.Plus be on the lookout for undervolting once bootloader is unlocked.
Came here to say exactly this ^^^
I think demandarin's comment pretty much sums up the best/latest approaches to underclocking available for the Prime. As noted, it makes the *most* sense with the LCD brightness completely down.
However, the only *real* way to qualitatively discover how much savings a strong underclocking scheme would have is to test it. When the time allows (testing battery life on these things takes a LONG time!! ) I'll end up doing this...

Here is the video i tried to take regarding the screen lag.
Its all real time , there is no , afaik any camera lag ( taken with sg3) , its pretty much how it looks . Also i have shown the FPS . You can see when i scroll slowly , the FPS drops to 20 or so making it jerky. if i do it fast , it reaches 50+ but not stable and not very responsive to my touch feedback either.
I have tried Bexus Kernel with OC GPU , still the same . Is there anyway to force the tablet to display at bare minimum of 30FPS ? I planned to read lot of PDF, but this jerkiness is giving me headache.
Can anyone help me ?
what rom are you running? no screen lag for me on a really old cm10 build. pretty much consistent framerate, though it is kinda slow
i think part of the problem here was B&N's choice of using a PowerVR SGX 540 GPU in this tablet. this particular GPU was also used in the entire original Samsung Galaxy S line, and is at this point 5-7 years old. not a particularly great GPU in my book. granted, we're not pushing a really high screen resolution (1024x600) but still, it's a really old GPU.
CM 11 Snapshot M5 i think. Using along with Bexus kernel.
I can lower the resolution if needed , all i want is a stable framerate display , ready to sacrifice some battery too.
I agree the tablet is kind of old , but i just want to use this as some secondary reading tablet. i have no use for it now.
Try turning off "Magnification Gestures". This has caused input lag for me before.

its off only`

A YouTuber recently done a video regarding does switching to a lower resolution actually save you battery. The answer? NO! It's just a myth.

I just saved 15% on battery life by switching to a lower resolution.
I just shutoff my phone and i saved 100% of my battery

Did you switch it to a lower resolution after turning it off though?
I didn't bother looking at the video sorry but, reducing the resolution does help with battery life, just not in a direct way.
When you're just browsing social media or replying to emails having a higher/lower resolution does nothing, as its mostly the CPU doing the heavy lifting here, but when you're watching videos or playing games, lowering the resolution will result in less GPU usage and sometimes also the CPU, which in result would consume less power.
For regular daily use the resolution won't make much of a difference, but if you're someone who consumes lots of Netflix or HDR videos, maybe play games like Pubg, fortnite or whatever a lot, you'll appreciate the little extra minutes lowering the resolution would give you, not to mention the extra performance that comes with it, as the GPU has less pixels to calculate.
The same concept applies to computers as well, its actually what Im basing my explanation on, but to get a precise results you'll have to do some tests/benchmarks with controlled variables.
If you play lots of games or watch lots of videos, you might wanna have the resolution at 1080p, otherwise 1440p will do just fine, the difference isn't that huge unless you're constantly forcing the GPU.
You wont with normal use. But you will with playing games at lower resolution, not to mention having a better frame rate!
Dont believe it. Try to play F1 mobile racing for about 1 hour and you will see!
