[Q] Is it possible to increase GPS sample rate? - Android Software/Hacking General [Developers Only]

Hi,
I have a Sony Xperia X10 (http://www.gsmarena.com/sony_ericsson_xperia_x10-2964.php) which has a Qualcomm QSD8250 Snapdragon CPU.
I was wondering if it is possible to change the sample rate of the GPS chip from whatever it is now (I'm guessing it's 1Hz) by modifying the driver (the driver is at /system/lib/hw/gps.qsd8k.so), or is it flashed into the firmware and something I cannot change?
I have looked at the disassembly of the driver, and it has too many exported API functions which I'm not really sure about.

Omap850 Cameras/General Opal Questions

Do all the Omap850 devices use the same physical camera?
The Opal uses the newer driver (HTCCamera1.dll) for cameras while the Herald uses the older driver (S5K3BAFX.dll) but they both have the same chipset (Omap850) and both have 1.9megapixel cameras. If the cameras are the same, can we use the Opal's driver on older Omap phones and get the ability to use the newer camera softwares?
Is the Opal nothing more than an Elfin with an updated set of software and drivers?
EDIT: Or does the Opal just use CameraDriver.dll and nothing else?
doubt it omap is just the cpu
it don't require or benefit from a single type of camera
anymore then an intel cpu in a pc benefit from having a
special brand of harddisk or webcam

True, but HTC is renown for reusing the same hardware with slightly different configurations. I was hoping this would be the case in this matter.

[Q] A better Camera App

Hello.
First of all, my compliments to everone that makes great things like custom roms, mods, and so.
I'd like to know if is there a way to mod/improve/change the camera app, so the shutter speed can be set.
Thanks.
Hello again. It seems this thread gained some interest, but no one could give an answer. What I asked was if is there any way to hack, develop, activate improved settings for htc chacha camera.
Videos are saved in 3gp format. Is there any way to make camera app to save them as mp4?
Pictures get blurry if the subject moves quickly, or you are not steady when shooting. Is there any way to set the shutter speed?
I don't know if the camera app can be disassembled or something, and hacked into make that things.
Maybe the camera app can be ported from another model that uses the same camera model, and can do that.
I asked HTC about this, and they answered "latest 2.3.5 version has many improvements", but none about the camera...
The camera is way better than Wildfire, which my wife owns, but I think it can be even better if the camera app is up to it.
Thanks for reading.
The big question revolving around this issue is if the cameras themselves are the same between the phones. It's not only the camera.apk that's connecting them, it's the hardware as well. Yes, there could be a possibility that the cameras are the same, between ChaCha and Wildfire (for example), but at the same time the proc or image sensor might be of a newer generation. Unfortunately I have no hardware specs on this, if anyone knows it would be nice to know.
Question: Do you know of any phone that has advanced settings inside the Camera.apk that allows you to set shutter speed? Would be interesting to compare them a bit.
In the camera.parameters public class there is a setting called scene_mode_sports that seems to be the only way to set a faster shutter speed.
I can't see it in my HTC Chacha/Status, and even lgcamera hasn't that option in the menu.
There is a profile.xml file that sets the limitations of the camera, but it seems people hack it to allow the camera to record movies in higher resolutions, because many times the limitations are imposed by the manufacturer and not the hardware.
Also, hacking the firmware and/or the drivers of a camera would allow to gain the full features of it.
This reminds me of people that upgraded the Nokia N900 to allow it to record movies in 720p, just by replacing binary files in the phone.
Is there an app that tells you what exactly hardware your phone has, and such drivers or modules it uses?
Thanks all.
Hello all.
I'm reviving this with some news. The camera module the ChaCha uses is a Samsung s5k4e1gx (http://www.samsung.com/global/busin...t/cmos-imaging/detail?productId=5622&iaId=220), the same found in several other HTC models: HTC Desire Z, HTC Mini and others.
It seems that in the Desire Z this camera is able to record 720p video.
I think this is determined by the firmware loaded for the camera, and the app itself.
I'd like to know if it's possible to port change the original ChaCha camera related modules and firmware from the Desire Z ones, so the camera can get taht 720p video shooting.
Also, I'm searching for a way to disable the auto light metering so a manual can be set. There are many 'better camera' apps in the market but they all seem to improve the original camera app itself, instead of getting the most of the actual camera sensor.
Thanks all.

[Completed] What model Asus is this? Any roms for this overseas rebranded device?

UPDATE - CPUz app said it was a dual core ARM CORTEX-A9 1.5 GHz, revision r3p0
Galaxy tab 3 has the same processor
Asus memo pad has it, but 4 core
Hello all,
I was in thailand and my phone died so I got a cheap $45 tablet to use whatsapp to talk to family and friends. I read asus makes the devices - I'm assuming that someone made this tablet for the company that sold it and that it's a little better than a cheap Chinese tablet quality bc it has had no issues and seems pretty good and was offered by a respected phone company over there. I wanted to upgrade to a newer Rom >4.2, now that I am back in the states.
1.) I had an adnroid stick PC and it seemed like the sticks where all the same chipset and then had roms you could load on them regardless of their brand. Are there universal roms I could look into.
2.) I'm not sure how hard it would be to make a CM rom for this device , but I did see that they have a link to create a build.
I'm going to try one-click, Kingo root, king root, etc to see if I can unlock it so I can turn off the telephony.apk and phone.apk since this one did not have a sim card and was wifi only. The manuf didn't delete those apps so they keep draining the battery looking for service.
Your help is appreciated and thanks in advance!

Question on UHD Video Recording Limitations

Hi All from Toronto, Canada!
I hope this is the right place to ask this. My question is as follows:
I have an Honor Note 8 with the Kirin 955 and the Mali T880. The camera on this phone is the Sony IMX278 RGBW sensor, which isn't the best as I hear, but is able to record 4k/UHD video.
From what I can gather, the Kirin 955 doesn't support hardware level UHD video encoding (only DECODING), and any phone with this SoC isn't able to record 4k/UHD video.
Would it be possible (albeit a lot of work) to record 4k/UHD video and either encode it at a software level (i gather this would be really slow), or even by using the GPU instead of the CPU to encode it? From what I can gather, the GPU is much more efficient as processing graphics and 2D video shouldn't be a problem at all for it. It seems like a solution to this would allow any user with this hardware configuration to be able to enjoy their phone cameras a lot more.
I know 4k/UHD video isn't really widespread yet, but I do have the necessary components at home including a 4k TV to be able to enjoy this resolution, so I am looking for a solution to this. Is it as simple as modifying the media_profiles.xml file and installing a different camera app?
I don't know a lot about android development, but I am making it a point to learn as much as I can, and I have put quite a lot of research into this idea before posting here, including searching on XDA. I work in Software Application Support for a small CRM, and I have years of experience doing mods and customization on android devices, so I am familiar with the landscape here and I should at least be able to understand any answer no matter how technical.
Thank you for your help!

I don't know much about Kirin SOC but with say QCOM to be able to encode via software using say FFMPEG the ISP would have to return preview frame with UHD Dimensions.
Its probably Capable of Encoding 4K maybe can check if it can be modded by understanding how everything works .
1st Check in /system/vendor/lib /system/lib/ lib64 for any file containing the word camera zip them attach them to your post
2nd download freedcam from play store in the menu scroll down and save camera parameters attach the file outputted to /DCIM/FreeDCam
Sent from my NX503A using XDA Free mobile app

A high quality 1080P/1440P USB DVR dash-cam for android headunits.

I currently suffer a VGA quality hidden USB camera which has been upscaled to 720P, the quality is poor, jerky and the app is chinese and full of bugs.
There seem to be some 1080P units available https://ebay.us/wcwg2H using the Novatek NT96658 chipset and a Sony IMX322 image sensor.
The quality of the video is reasonable on this hardware and the H264 compression is much more efficient than my MJPEG based camera.
The playstore is full of good apps which are compatible with this hardware but they are all wifi based as is this camera. This would mean choosing between internet or dashcam which is not what I'm looking for.
I have come across a few dashcams which can connect to a hotspot like the BlackVue units but they insist are slow over wifi and stop recording when accessing the camera over the app. USB is definitely the answer!
Some dash cams support a USB OTG connection for downloading files and maybe a solution.
Has anyone else come across a decent solution? I don't want my headunit recording from a USB camera due to system overheads. My 4GB PX5 head unit is smooth and snappy and I don't want to lose this.
Any ideas?
