they're already enabled. next.
Jodova: if you don't understand the question then don't answer and display your ignorance. He's asking about enabling all right at the same time, not the big.Little configuration they're in now.
Hopefully Samsung will enable this soon.

I can't imagine needing all 8 cores at the same time. It seems it works great under heavy loads as is.
Forgive my ignorance but, would we really benefit? It seems to me it would absolutely destroy the battery.
Is there any octa-core device running all 8 cores out of the box?

I attached a image for your question. It looks like Galaxy S5 should support enable 8 core. I think Little Big is designed for beautiful scoring not for daily usage.:banghead: I prefer to choose the latest Snapdragon Chip

I expect my next Tab or tablet could have enough powerful processor which is able to make me forget my windows laptop. Battery killer? Samsung ROM is the best battery killer

Exynos 5420 + HMP = Exynos 5422. So no, Exynos 5420 which is in the S doesn't (and won't) support HMP.

Here's a slide from Qualcomm. The same holds true with Exynos where 85% of apps never leave the A7 cluster. In a few instances using A7 and A15 at the same time might provide needed extra power but how many apps or games exceed the power provided by four A15 chips?
Check out this:
http://www.slashgear.com/samsung-te...lementation-for-exynos-ahead-of-ces-29310253/
In this article. from Dec 2013 , more than 6 months before the tab S was released, a "Samsung Engineer" is quoted as saying:
'The ARM-based Exynos 5 Octa is currently used in a range of Samsung tablets and smartphones, but only one Exynos model, the 5420, is hardware-enabled for HMP. The 5420 is currently found in the Galaxy Note 3 and Galaxy Note 10.1. However, HMP is currently software-disabled because HMP would overheat such devices, a Samsung engineer stated.'
Samsung announced two new mobile SoCs at MWC today. The first is an update to the Exynos 5 Octa with the new Exynos 5422. The 5422 is a mild update to the 5420, which was found in some international variants of the Galaxy Note 3. The new SoC is still built on a 28nm process at Samsung, but enjoys much higher frequencies on both the Cortex A7 and A15 clusters. The two clusters can run their cores at up to 1.5GHz and 2.1GHz, respectively. The 5422 supports HMP (Heterogeneous Multi-Processing), and Samsung LSI tells us that unlike the 5420 we may actually see this one used with HMP enabled. HMP refers to the ability for the OS to use and schedule threads on all 8 cores at the same time, putting those threads with low performance requirements on the little cores and high performance threads on the big cores.
The GPU is still the same ARM Mali-T628 MP6 from the 5420, running at the same frequency. Samsung does expect the 5422 to ship with updated software (drivers perhaps?) that will improve GPU performance over the 5420.http://www.anandtech.com/show/7811/samsungs-exynos-5422-the-ideal-biglittle-exynos-5-hexa-5260
The Exynos 5422 in the SGS5 is running at the same clock speed as the 5420 vs. the higher speeds it's capable of supporting. So it's highly likely 5420 and 5422 have the same heat envelope.
@AndreiLux is a leading kernel developer on XDA. You can review his comments on 5420 ever being able to support HMP in this thread. I'd take it as gospel. Getting HMP working where it's disabled is kind of like threads about reversing KNOX after it's tripped. Both are urban myths.

It's not impossible for the 5420, it's been done and I've seen the Samsung patch (I linked the patch in another thread in our forum somewhere). As far as I'm aware, it just hasn't been done on Android. It may require many changes including Linux version, governor etc etc
I personally (just guessing) think that Samsung haven't bothered for our device because of heating issues and invoking thermal throttling at an earlier stage. For most applications, such power would not be needed.
Edit: OK, the patch I quoted was for 5410, but I've seen similar for 5420. ...
This is the thread in I'm referring to previous discussion.

If Samsung invested the time money and resources, I'm quite sure that is not "impossible" to do it for our device. Due to the above stated reasons, I feel it's quite "improbable".

Do you really want to argue with me? The CCI is disabled in hardware on the SoC and it's impossible in any kind of way to circumvent this via software. Beyond that we need changes to the bootloader to be able to properly manage booting of the clusters as the PM is protected/handled over TrustZone.
You will never see HMP work on any 5420 on any publicly available hardware. Period.

You know that i wasnt arguing...... My point was that's is not impossible (video evidence !!), but improbable. Samsung have the resources to do just about anything they put there minds, money and motivation too. I also referred to generally 5420 , and not our specific device......
I agree on your last statement (edit: for existing public available hardware), The demo 5420 HMP clearly works.
Hello everyone,
let's make it as short as possible. As the title says, there are plenty of Polaroid tablets with not-bad specs ( one core arm cpu clocked at 1Ghz or more) that need some of the Devs magic. For unknown reasons, the manufacturing comapny, the very famous Polaroid released the MIDC range and left it without any upgrades and I am sure their forums is full with threads begging them to give our old but much loved devices upgrades to newer android versions or just updates to fix bugs and add some nowadays necessary features.
And here I am, the unelected spokesman of all Polaroid MIDC tablets owners, looking for some attention and care from our beloved XDA-devs to do something in regard of this cause.
Thanks in advance. I am totally willing to pay Devs for this cause and want to try Google now on my device please.

I got ics on my pmid10c. Polaroid strung me along from when i bought it new in 2011 until this year about kernel source.
First, "the device is too new for releasing kernel source."
Later "we're referring that question to engineering who'll get back to you."
Never heard back after any of my many many phone calls and emails, until the last time when they actually called me back.
"The device isn't supported anymore, the factory that built it is closed, and we don't have access to the source code now."
Worthless manufacturer.
I talked with another developer here on xda about kernel source, the sunxi kernels build and boot but lack support for the extra hardware like touchscreen and sound and gps etc.
Find me kernel source and maybe i can help out.

It's Ok, mine is dead now! it won't start no matter what I do to it.
Thanks a lot for your interest.
There is a lot of debate over the performance between these 2 versions. So put 'em up. Any test or source you feel is relevant to your stance. I'll supply my 855 scores for a few. Please keep it friendly.
My OP didn't post the screenshots correctly.
Xda just takes a while to actually show attached images. Your first post was fine.
In synthetic tests the Exy should be faster, and rightfully so. It occupies more space than the SD855, so I suspect Samsung scaled perf back to match the 855. Now, the SD will probably run better than Exy in emus and native games.

Unless Exynos broke the mold this year, gaming is smoother on SD. If an Exynos user could start posting their results, that'd be awesome for the benchmark debate.
Are you saying that the 9820 is physically larger? If so, Qualcomm did implement a 7nm process to combat the difference.
Can you check what camera sensors you have?
I downloaded AIDA64 and it says I have ISOCELL in my S10+ Exynos version.
I want to know if Samsung is placing Sony IMX sensors on the Snapdragon variant.
I have used Antutu and Geekbench for the scores. Did not do anything else basically. Didn't know if I should have messed with some setting or had to restart for a better score. If I have to do the tests again, please let me know.

Yes, the 9820 is larger than the SD855 and 9810. When it comes to games it's hard to gauge the Adreno, since PUBG already runs at 60FPS on the 835, or with HDR on. That means it'll be a while before the 845 starts to choke.

Nah mate you're going too far in misunderstanding about this whole tech.
ISOCELL is also not a brand but a technology name for sensor produced by Samsung, Sony's counterpart is still using barely improved version of BSI, an older technology.
In theory, ISOCELL is superior to pretty much everything else, the only way for it to lose is to have inferior processing, the Pixel 3 makes good use of its IMX363 even if it technically has an older system.
Regarding ISOCELL vs BSI on the same device and same software processing will always come with better result through the ISOCELL. DXomark's review of the S10 used the International version with a 4.32mm ISOCELL, and it is the first in its class.
Also, the IMX sensor in @sireniankyle's screenshot is the selfie front facing camera, you can see the other rear facing camera being an ISOCELL (ultra-wide 1.80mm) as well.
I have attached my Exynos AIDA sensor screens and one of DXOmark's benchmarking sample with the sensor data recorded.
To keep it separated from my previous post:
@twelvematic You shouldn't sell your G975F, we have:
-30%+ more single core performance
-equal or in some cases superior GPU performance (check my other post on the thread)
-unlockable bootloader at any time
-updated proprietary sensors that Samsung has full control on
-proprietary SoC that Samsung has full control on, most OEMS have no control over whether or not Qualcomm will continue supporting their platform with libs after 2 years, that's why most Qualcomm devices started having dead or crippled AOSP support in the last years, it turned from being community friendly into becoming just another American toxic corporation, it deserves to die like one, their patenting game is also dishonest and illegal in many cases.
-potentially superior battery life, Snapdragon users aren't even getting close to my 13.5h SoT record, their battery life drama percentage seems to be higher than ours (battery optimisation guide is coming soon btw)
If anything isn't performing in a satisfying way I am fully assured it can be solved with software updates. This affects all new technologies, and Qualcomm is not the new boy here.
Samsung has the means, they have the experience and media has already applied pressure on this Exynos vs Snapdragon issue for quite some time.
I was very negative about Exynos being potentially lame while waiting for my European pre-order, I do not worry anymore.

GPU equal or superior? Lol. It's not even better than the Adreno on my Note 9. Not only in the benchmarks... It is clearly noticeable in PUBG Mobile. Mali GPU lags.

Renderscript is very unrelated to 3D performance, and it's also extremely dependant on kernel optimisation.
Why don't you run GFXbench on the Note? You will see what I'm talking about.
Samsung should improve their kernel optimisation game, the silicon is great, they're just lazy, at least my battery is insanely good and no Snapdragon is minimally getting close. That alone is worth more than any loss in benchmarks.
I had both S10+ Exynos 9820 and Snapdragon 855 for a night before selling the Exynos model. Here are some tests which you can access from my google drive folder.

- Antutu
- AiTutu (AI performance using NPU)

Although not Philips, Sony or TCL, I can't find a more appropriate forum to post.
I have a Kogan 40" AndroidTV (KALED40QF7000SKA). It has an ARM A53 SoC, Mali 450 MP4 GPU, 1.25GB RAM and 8GB flash, running Android Oreo.
I found a firmware upgrade file called upgrade_loader_sign_common_190124.pkg on their site. The name is similar to HiSense's firmware upgrade files, suggesting a common bootloader.
I am keen on tinkering with this set, possibly rooting and running BusyBox, writing small C apps for custom I/O, etc, but cannot find any technical documentation for the bootloader or a toolchain on the Internet. Can anyone suggest where to start?
I'm keen to participate in any community that's doing similar stuff, and have some time to contribute.
Update, March 25 2020 (1:50AM ET): Qualcomm has confirmed more GPU driver update details, and it looks like you shouldn’t expect these updates to arrive every month.
“Qualcomm is committing to a quarterly cadence for release of updated drivers to the OEM,” the company told Android Authority in response to an emailed query.
The OEM then needs to push out this GPU driver update to the Google Play Store or app stores in China, and Qualcomm says it’s hoping device manufacturers stick to a quarterly release schedule too. But how long will these updates last for a given processor though?
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Original article, March 24 2020 (5:33AM ET): Qualcomm announced the ability to deliver GPU driver updates via the Play Store back in December 2019, initially saying it would be limited to new chipsets (starting with Snapdragon 865 and 765 series).
Now, the firm has announced that several Snapdragon 855 phones will be first to get GPU driver updates in this manner (h/t: 9to5Google). These phones are the Samsung Galaxy S10, Samsung Galaxy Note 10, and Google Pixel 4 series, with Qualcomm saying more devices will get the feature “later.”
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
The announcement comes as part of a partnership with Google for the Android GPU Inspector tool for developers. This profiling tool allows developers to inspect mobile GPU usage (including Qualcomm’s Adreno GPU) in games to figure out where improvements can be made.
In fact, Qualcomm claims that Google and a developer partner used the tool to deliver 40% GPU utilization savings in an unnamed game on the Pixel 4 XL. The silicon designer said this optimization resulted in a faster frame-rate and better battery life.
Qualcomm also confirmed that it would make a beta version of the Adreno GPU driver available to select developers, who can then give their feedback and suggestions for future driver updates.
“The final drivers will also be available in the Google Play store on select devices. Consumers will be able to update their Adreno GPU driver just like an app,” the company reiterated.
We’ve contacted Qualcomm to find out more about GPU driver updates via the Play Store, and will update the article when they get back to us. We’ve also asked Samsung whether this feature is restricted to Qualcomm devices and await a response. But it certainly seems like a welcome feature, as it’s poised to deliver smoother performance for budget phones and for flagship devices (especially as time goes by).
Source of news:
Qualcomm: https://www.qualcomm.com/news/onq/2...-now-faster-google-and-updateable-gpu-drivers
And AndroidAuthority: https://www.androidauthority.com/gpu-driver-updates-phones-1096423/
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
hopefully this will bring further improvements to our device in the near future
Really happy with these news!
This is awsome! Finally!!! Waiting for that
I just miss some fluidity vs games-apps when the phone is hot, because after 20-30min playing PUBG mobile 90hz, phone is a bit hot... so when I have to change between apps, sometimes it's a bitt lagged, or frame dropped in the game. I think is because of the hot, but maybe is something not optimized. A10 M3.0 stable.
Did you guys listen some ETA?
Didn't read anywhere it will come to rog 2 but good to have hope though.
