First of all, I'd like to thank everyone involved in this site. The experience has been very enriching so far.
I have a Cherry Mobile Razor which I bought here in the Philippines. Specs are as follows:
- Mediatek MT6589 Quad-core Cortex A7 Processor
- PowerVR SGX 544MP
- 1GB LPDDR2
- 540x960 qHD IPS LCD Screen
- 4GB Internal Storage
-16 GB SDcard/ External Storage
- Android Jellybean 4.2.1
- 1750mAh Battery
Now, it is a sweet device for it's price point. Catch is, the screen refresh rate is locked to a snail-pace 22Hz. That's right, 22Hz. The big difference between the amount of frames the device can process and the rate it can spit images out on the screen is so big it shows as a laggy platform for a myriad of 2D applications. You can even feel the "display latency" when typing on the on-screen keyboard. The animations are fluid, but laggy response can be felt.
The question:
I wish to edit the refresh rate setting on the device and set it to about 60Hz. I am rooted and read somewhere that settings are located in the kernel. I am thinking of editing the boot.img in my device, either the manual way via ADB or through a kernel kitchen. But before I do any sort of unpacking, editing, then repacking - am I looking at this correctly?
Are there other things I need to consider and know like LCD screen specs, etc.,... ????

Hi all,
I have been developing a small android app which is sort of a reader for results coming from a desktop application. Some of these results are in the shape of a 3-dimensional structure made of a number of basic geometries, which I have been generating using a library which I coded in C++ using OpenSceneGraph and compiled with NDK. I have tested my app on both my HTC 3D EVO (before on stock rom, then on a few gingerbread custom ROMS and finally on a few ICS roms too) and also on a crappy 7'' chinese tablet which I bought really cheap a while ago. This tablet has a pretty basic AllWinnerTech A10 single core 1GHz processor, 512 Mb RAM and a Mali 400 GPU. So nothing fancy at all. However in all my tests I get about 2 to 3 times as many FPS from the tablet compared to the EVO. The structure can be moved, zoomed in and out much more smoothly. Remarkably so!
Am I missing something obvious here? Is there a "turn on graphics acceleration, you idiot!" button which I have not found yet? I mean, just in terms of specs I would have expected the EVO to run circles around that tablet.
Has anyone got any idea?
Cheers.
Have you tried forcing HW acceleration threw your build prop to see if makes a difference on your setup??
#Root-Hack_Mod*Always\
debug.sf.hw = 1 already. anything else in the build.prop file that may improve this? Could it be a drivers issue, or is it just me expecting more that I should from this phone?
Are you hitting the frame limit cap ?
what would the value of this cap be? I barely go above 15-20fps on the smallest structures. anyway, don't get me wrong: I can live with it.
It was just curiosity, because I expected much better performance from the EVO. and so I was wondering where/what is the bottle neck
From what I understand HTC shipped the EVO 3D with terrible drivers, I think that they fixed this problem with the ICS update. With these drivers the Adreno 220 is able to surpass the Mali 400 mp4 (galaxy s2 version) in some situations.
so will the gnex be a high end phone as in having desktop convergence? according to their website, for it to be a high end phone, it needs to have a quadcore a9 processor. otherwise it fulfills every other aspect. this phone has a dualcore a9 processor, so will there be desktop convergence. I really hope there will be I want to try it out.
Well from what I saw, every video demo etc. Was specifically the galaxy nexus. At one point I did see "a" phone connected using the desktop feature. Each phone I saw using the Ubuntu mobile has been the nexus.
Edit : I've also heard the specs released aren't final and just a figure for certain phones.

the entry specs are
1Ghz Cortex A9
512MB – 1GB
4-8GB eMMC + SD
Multi-touch
hig end specs are
Quad-core A9 or Intel Atom
Min 1GB
Min 32GB eMMC + SD
Multi-touch
so i think The Galaxy Nexus is just a "normal" UbuntuPhone device

that's OEM specs, which doesn't mean much for download/install version potentially. The values of which would have been decided are best to give the full desktop experience - including downloading alot of desktop apps. Time will tell, but I suspect desktop version will run perfectly on GNEX, or any other internal memory only phone - it's just a matter of keeping your eye on space available when you are installing Ubuntu native apps.
I'm also wondering if the Desktop Feature will simply be disabled on devices with lower than recommended specs. I have seen some Ubuntu on Android videos using a Motorolla Atrix II which has exactly the same hardware as the GNex. It ran the desktop and even Ubuntu TV pretty good considering it was early in development (1 year ago) and running ontop of Android with bridges to access the phone settings and apps.
Hello,
I bought this smartphone on aliexpress in what appeared to be a good price:
http://www.aliexpress.com/item/Unlo...ne-1-5G-4-8-QHD-1280X720-1GRAM/726280982.html
(DO NOT BUY IT!)
Declared to be a quad-core Nvidia Tegra 3 to 1.5 Ghz, 1280x720, 1 Gb Ram Android 4.2, and the rest of the features that you can see in the link.
I got the phone and with my unpleasant surprise I discover that it is a dual core 1 Ghz MKT6577, 854x480 with 512 Ram.
Launching the Antutu Benchmark, in device info shows (summary):
Model A9
Device GNET A9
480x854 resolution
cpuinfo Dual core ARM v7 processor
While on System info shows (always summary)
Nvidia Quad core cpu model ARMv7
CPU Frequency 1500 Mhz
Screen resolution 1280x720
Ram size 1024 (Free 64!)
Android version 4.2.1
I have installed a bounch of information system apps and unfortunately for all of them the specs are the lower ones,
Pretty sure now that it is an MTK6577 dual core 1 Ghz 480x854 512Mb ram and android version is 4.0.1
It is possible that they have "modded" or faked something in the phone to make possible to show
different features only on antutu benchmark?
If so how can I prove it?
Tomorrow I will open the dispute.
Thanks for the help you can give
This is usually the case with cheap Chinese phones and tablets. All pretty much the same specs as yours. The details that show in system info are easy to fake. Doing so just involves editing a file called build.prop in the system folder.
To view this file, download a file explorer app like ES File Explorer, open it, it will open to your internal memory/micro SD card. Press back once or twice till you see a bunch of folders, one of which will be 'system'. Open this folder and inside you'll find a bunch of other folders and a file called build.prop. That's the file you need to open. When it asks you what to open with, choose ES Text Editor or any other text editor that's there, and view the file.

thanks sashank
it is the answer that i needed.
Another question is:
it is also possible to falsify the antutu scores?
Because i get around 6900 that is pretty fast
for the processor involved.

yep it's possible. a video even showed huawei's code in 1 of their phones cheating benchmark applications
It is long known that all benchmark scores can be faked even by the newest of noobs. They mean less then nothing really. Put no faith in them. And remember this piece of advice. If it sounds too good to be true, then it is.
In this day and age people are too fast to trust something on face value. Sad as it may seem this is not always the case. With the open nature of android anything is possible. I can give you a device that says it has an Octo-core S10 with 5gb of ram. A full HD 3D display that scores 90,000 on bench marks. All the while it is a pos that is sending out hundreds of SMS to a premium number as it silently grants root access to every request without user knowledge. See my point?

Thanks all for the support,
i have solved the dispute with the seller, he is very new in ecommerce and i think he has been cheated before me, and i consequently, he has been very fair and we agreed for a 50$ refund, that bring the phone around at its real price. This is a bit annoying, because it is not the phone that i wanted to buy, but at least it is not so bad and it works good, i will keep it for a while, waiting for new models on the market.
I'm looking for hardware device on what compact device to hook up to my HDTV for turning it into a media center primarily and a light PC otherwise.
I'm interested in something like the RK3066 because it seems to have decent performance compared to the older single core devices.
Things it needs to do:
- run XBMC, stream media from fileserver via wifi
- stream another display to it in 1080p
So.. basically run Android or Linux effectively enough. This one supports bluetooth which seems useful for peripherals.
Things I might do with it:
- put linux and steam on it
- light browsing ans basic gaming
- hook a webcam to it
I've built full HTPCs before and I don't think I can do a compact one for anywhere near this price, even though it would be way more powerful. I also don't want a single purpose 'streaming box' solution that I can't replace the OS on. I see this as a cheaper way of doing 99% of what I want and I can still choose to replace it at anytime without feeling bad about it.
Any better performing options at this price, or similar options at lower price? Alternative hardware that I should be looking at?

if you have a bit of patience a few new ones based on rk3188 are launching that are a lot better, not only they are way faster (quad core, faster gpu, 2gb ram - around 18k antutu just as reference) , they solved the overheating and EM interferences that plagues rk3066 ones.

That's exactly what I wanted to know, since I'm not normally following the latest for this type of hardware. Do you know when these might be available?
Not sure where this should go as searches for my specific model (CP-DX650) yielded no results.
I've got my hands on a Cisco UC Phone model CP-DX650 and I was wondering if there was any interest for development.
Specifications:
Display: 7 in. diagonal; backlit, WSVGA capacitive touchscreen LCD with 1024 x 600 pixel effective resolution

Depends on what you're trying to develop. The phone is OMAP4 based processor, and system image is fairly straight forward. One ""MAY"" be able to build a new system image with supersu integrated... The phone does have a microusb port to do ADB commands with...
