Right now it is at 1hz, which is way to slow for a couple applications I use. Is there any way to raise it to 5hz or higher?
This has nothing to do with Android Development. Please post in correct section.

And which section would that be?
General...
I'm going to have to agree that this is most directly related to android development. Definitely more relevant to development than general.
Second that agreement. Development question for sure.

That's what I was thinking since you would be modifying part of the android OS...
Anyways. I heard it was possible to do, I just have no clue how. I'm sure a lot of people would like it if someone wrote an app that could change the gps polling rate.

How do you know what the highest GPS refresh rate is?

I know the default is 1Hz from the app I downloaded that tell you the gps polling rate. External bluetooth GPS receivers are 5hz and up, but the incredible doesn't support bluetooth GPS.
Taking a look at the SDK which is what someone would be using to access the GPS via a program, it appears you can set the minTime in milliseconds. But there is a warning that says:
Background services should be careful about setting a sufficiently high minTime so that the device doesn't consume too much power by keeping the GPS or wireless radios on all the time. In particular, values under 60000ms are not recommended.

However, that doesn't mean the GPS itself is polling that fast, that is how fast you are asking for what the GPS currently has. There does not appear to be a way to change the GPS polling itself.
I'm guessing this is set by the hardware and not changeable and is set by the mfg of the device. Most likely not nearly as customizable as some GPS units you can access via bluetooth or USB device.
Power is a big limiting factor.
Someone with some actual development experience might be able to provide more info on this...
Well, If it can't be changed onboard, then maybe something to make the incredible work with bluetooth GPS devices?
Pure GPS can only give you a new location once a second. To get faster updates than that you need to blend the solution with something like an Inertial Navigation System.

Yeah, what he said. Besides, if the GPS rate is good enough for the Speedo programs on the market, how could 1hz not be fast enough
I'm pretty sure GPS can sample much more than once per second. I have a pretty expensive Trimble unit at school for an autonomous bot and it allows for up to 20Hz sampling in standalone mode.
bumpity bump.
I know higher ghz doesnt mean better but just for fun.
Lets share some overclock experience here!
I am using tegrak, running 2 ghz now. Never experience rebooting yet! And done all the test bench.
Can you please give the detail here how to set the CUP o/c up to 2.0 mhz.... Thanks a lot!
here is my setting below..i am not professional! Comment is welcome!
Nice... Do you "feel" any difference in performance? Is it worth it?

Can you walk through how you did this? I'm new to overclocking, but understand the concept. I only show up to CPU 5 and I noticed the picture you posted shows up to CPU 7. When I go to CPU 0 to adjust it to 2000, tab just reboots. Not having any success in applying the changes you've shown. Are there any other settings you haven't shown that are necessary to make these changes?

Wow, its amazing how people will just go ahead and blindly do whatever someone else does without thinking anything through.
the Samsung Galaxy Tab 7.7 is based on the old A9 cortex we know and love, and at 1.4ghz is already fast for the specifications it was originally designed for. I would think very carefully before just plugging right away with a 40% increase overclock on your very expensive and prized possession tablet. If you break it via crazy high frequency speeds, and Samsung engineers would have little trouble identifying the cause in a repair shop and your warranty will certainly be void.

wow, it's amazing how people just assume everyone else around them are idiots and are completely oblivious as to the detrimental effects this can cause to their tablet.
I know quite well the dangers of OC'ing a PC and Tablet.
Back to the OP. Can you explain how you've done this?
Wow 2Ghz at 1.3Volts

You say you are new to overclocking, then say you tried to directly apply 2ghz and the tablet "just rebooted". Forgive me for assuming you don't quite know what you are doing.
I'm calling shenanigans on this post... Those settings are just bollocks, unless the OP somehow managed to get their hands on a prototype 5 series Exynos, which CAN handle speeds like that...

I never claimed to know exactly what I am doing, which is why I asked for help explaining how it was done. I said I understand the concept and the detrimental effects OC'ing something can cause.
If you don't have something useful to contribute to the thread, don't waste yours or anyone elses time by posting.

Yup, I can imagine the CPU handling it for as long as it takes to reach unstable temperatures... 0.5-50 seconds. Not to mention the voltage i can imagine required to keep it stable at such a high frequency.

The useful thing I am contributing is trying to drill into people that just because you see someone else do silly things on a $600, doesnt mean that you should do them too.
Tablets are not desktop PC's, they are 100x more delicate and do not have close to the tolerances or tweakability that PC components enjoy, and the risk of breaking something is much greater. Going straight for 2ghz before testing stability at lower speeds (as you did, hence the reboots) is just careless, no two ways about it. However, feel free to go ahead, just don't complain here when all of a sudden it doesn't power on any more.
moving right along
colour me skeptical (of 2ghz)
I want to disable vsync to test a certain app to see if a timing issue still exists or not. Any way I can disable it? There seems to be some device-specific ways to go about it, but nothing universal from what I've seen.

I actually already posted this for you in Ktoon's kernel thread.
echo Y > /sys/module/sync/parameters/fsync_enabled
(N for disabled)
But it needs to be exposed in the kernel for you to be able to control it. Franco's kernel is the only one that I know for sure has it exposed.

fsync is not the same thing as vsync
fsync is the thing that can improve I/O speeds at the cost of integrity; vsync is the thing that caps overall framerate with the screen refresh rate.

Thanks for clearing that up. And this actually goes in the build.prop.
debug.gr.swapinterval=
0/1
This is as close as you are going to get to "vsync" since it doesn't really apply to phones and tablets in the same way "vertical sync", as is found on a PC monitor. If you actually disable the similar function on these devices it would become pretty much unusable. This disables the FPS limiter.

hmm, from what I hear, debug.gr.swapinterval is deprecated, and replaced with debug.egl.swapinterval and FPS is still capped at 60.
What about "disable HW overlays" in developer options? As I understand it, "HW overlays" aka HWcomposer aka Project Butter also includes a vsync component so maybe that gets disabled with HW Overlays?
just a thought and I may be completely off the mark here...

Hmm, not too sure. In any case it seems to lower FPS quite a bit below 60, so I can't actually tell if vsync is on or not lol
noobs
sys/module/DC/parameters/no_vsync
Change from 0 to 1.
This disables VSync, which is seemingly not the only thing that limits FPS in our device.
or u can just install pimp my rom rom from play store
LE: i disabled it some time ago but im not sure if it does anything good. I remember that on PC games disabling it improved the performance, same story on android?
Hey
adding debug.egl.swapinterval=0 in build.prop should be working for Snapdragon 200, 400, 600, 800 line of SOC-s.
Tested with Snapdragon 400, Under Android 4.2.2., Reffering to the FPS meter in Quadrant Benchmark, there is no more limit .
(Tested using HTC Desire 601)
Guys I know this is a noob question but I need to know what is goodix word which is frequently used in our forum is that related to fps? Then what is the difference between fps and goodix?

It's a manufacturer whose scanner was used during production of particular model of the device: either it's Goodix or FPC. It is related only to fingerprint scanner.
Hi all am trying to make shamu record at least in 60 fps (120 ideally) ,can someone provide me the .so files needed for this to happen or can someone tell me how to edit them ?
sorry if this is the wrong section if so, move please!

I doubt that shamu's cpu is powerfull enough to handle that load.
Also changing some *.so-files won't help much as it needs changes on device side an the kernel driver.
So if you're not into programming and endless debugging sessions - abandon all hope.

That it can do it, it can. Now i won't eat my youth over shamu and his labyrinth of coding i already locked my eyes on the new Xiaomi Note 10 or the 9 Lite ,when shamu's battery goes to sleep with the fishes... they can go till 1000 fps ! Its just weird coz other phones with the same cpu and/or same camera sensor can also go 120 not even 60 ... but since i don't know my Jesus about android programming i acknowledge my defeat from Google and move on with my life
