wifi6? - Redmi K20 / Xiaomi Mi 9T Questions & Answers

Snapdragon 730 is supposed to be wifi6 802.11ax compatible but that's missing from spec sheet of this phone. So is there a way to tell it's there or not?

It's not there. Some features aren't included by default and it's up to the manufacturer to make them available.

Snapdragon hardware multimedia support, possible?

Hi!
I've been trying to find any documentation on Snapdragon's DSP and hardware based video and audio decoders. So far, nothing. I'm just thinking if it would be possible to cook the support into custom ROM as it is quite ridiculous that decoding something like MP3 or AAC takes any CPU time at all, as according to Qualcomm's web site Snapdragon has hardware support for decoding MP3, AAC and H.264. I take it Qualcomm only provides the documentation to partners, as it is impossible to find?
Hopefully full support for hardware acceleration comes with WM7, if it can not implemented on 6.5. Should be doable with custom driver (in kernel mode) anyway by cooking, provided the documentation is leaked or something.

It's not possible to have the SnapDragon documentation because Qualcomm will never release it.
It's possible instead to have the missing SnapDragon drivers for Linux or I hope for Windows CE only when a QSD based smartbook that will have these drivers will be out.
With Windows Mobile 7 it's a whole new story, new CE7 kernel and support for all the new ARM instructions. I hope that we'll get that things and soon

That's a waste of potential, but we can only wait (or not? )
you Cant really expect qualcomm to release documents on its IP.
but it would be nice if they and htc worked together to release a dev sdk.
if they are serious about developing the platform then its a step they really do need to make.
if samsung can get a sdk out for the omnia ii then it seems sensible to think htc need to play catchup.. the chipset does have potential,and it appears qualcomm are becoming more dev friendly.
look at what southend have achieved with some decent support from QC..
documentation?
Qualcomm should be giving documentation to ISVs its just a matter of it falling in the wrong(or right) hands. In the meantime, Snapdragon uses ARM Cortex-A9 core and you can find more details here:
http://www.arm.com/products/CPUs/ARMCortex-A9_MPCore.html
Not sure if that includes DSP.
My acer s200 has support for H.263, H.264 out the box =]

Snapdragon is Cortex A8 based and yes it does have DSP

Do you know are the hardware multimedia decoders really silicon or SIMD/DSP based? From the QC's documentation you get the feeling they are ASIC stuff, but it might be marketing and in reality they are IP cores.

Possible to have android on a U8 smartwatch?

I've ordered a U8 smartwatch off Amazon.co.uk and when I get it I want to toy with it but I am just wondering if anyone has attempted to put android on it?
not possible, specs are way too low for that
What about the u10?
Could you put android on the u10 smart watch?
no
even though RAM is bigger, it's still only 128mb
processor is only 300mhz
chinese smartwatches don't have the specs to run anything but the limited firmware they have preinstalled

False. There are multiple Chinese smartwatches that run Android.
hmm, i was thinking android wear, android would require a cellular modem, no?
Not necessarily. The cell side in Android can be hidden, like how a lot of tablets have hidden dialers in them even when they didn't have cell radios. I would not be surprised if there's a lot of cellphone specific code in Wear as well.
As far as Wear, if one had full source they could compile a working Wear build for a number of Chinese smartwatches. In fact, Com1 did it on their prototype, but because they were not part of Google's exclusive "Wear Partners" club, Google shut Com1 down.
for both android and android wear you'd need drivers though, to access all hardware, so you would need a kernel specific for the watch
available?
Most Chinese smartwatches are MTK based, so no.
so it's not possible then
Depends. The TS has a custom ROM and git which was cobbled together from multiple bits of sourcecode. It's mostly a matter of how much work one wants to put into it.

SnoopSnitch

I'm going to apologize in advance and hope there is someone who is patient enough to try and deal with me because I'm a complete idiot when it comes to anything electronic. So, I'm sorry. But any help is appreciated.
I recently downloaded SnoopStitch but when I opened it, I get a error message : Fatal Condition device not Compatiable. Device does not exist / no Qualcomm chip / no ROM
So, I know it exists. I thought it was on the device list when I went back and looked but I don't know for sure because it seems as if there is actually 700 different S4's and I have no idea which mine is, I guess. I think.
And I think ROM has something to do with memory but I don't really know and I have no idea how that would help.
So far as I know it is just a normal Samsung Galaxy S4 bought last September through Bell Mobility in Canada.
Is there anyway I can make it compatiable? Can I get this Qualcomm thing?
Thanks,
Judas
ROM is android itself, the operating system on the phone, the whole software part. The ROM is what makes this device an android phone.
Qualcomm is the hardware manufacturer. More specifically, the processor and graphics processing unit.
The S4 came in two variants, a Qualcomm variant and an Exynos (Samsung's own processor) variant. You have the Qualcomm variant.
The Bell Canada version of the S4 is an SGH-1337M.
If your device does not appear on the compatibility list, there are certain ways to make the app think it's a different device. But let's get into that once we are certain it isn't.

But we know, don't we? Or is it the ROM?
I was going to add a screen capture I took of the error message but I can't figure out how to upload a picture.

SnoopSnitch requires root and stock rom (Stock rom meaning the factory pre-installed software).
Since you claim to be disinclined towards technology, I assume you have the latter, but not the former. Am I correct?

Well, then you will have too root your phone.

Europe's Galileo Satellite Navigation System compatible?

Hello,
Is the nexus 6p compatible with galileu gps system?
Or is it possible that in a near future becames compatible?
According to Qualcomm, SnapDragon 810 is not compatible, while 2016 processors (820/821 ...) it is.

I'm a little bit confused, because I've read this on another website:
According to Qualcomms website the Snapdragon 810 (like in my Nexus 6P) should support Galileo. But no doubt they'll refuse to release the necessary driver or code so people have to upgrade to a newer phone if they want it.
https://www.qualcomm.com/news/relea...cessor-powers-premium-tier-mobile-experiences​
Galileo and Gps uses the same frequency for L1 band so on hardware side it should be OK. Now for the proprietary drivers is another story..
Are there other receivers already giving good positionning? Last time I check there weren't all spacracfts launched ? They had stability problems on their clocks.
Are they any news on snapdragon 810 support for galileo? It will be possible to make it work? too bad that Qualcomm says first it supports galileo and then only new processors will support it.
If there is not a problem with hardware I am pretty sure someone can force them as they advertise 810 as galileo supported. Usually what you advertise you must bring to buyers.

RAM, can it be upgraded?

Let's think on the event that you do have knowledge and tools and skills to perform such "surgery", also disregard the possible costs.
Is it possible to ?
I've seen in an app that my phone the xt1640 witch have only 2gb instead of 4 like the other variants, uses Samsung ram modules, meaning that they can be brought and used right?
Although I've heard that ram is actually part of the SoC,in this event, could one get the chip from another variant that have 4gb and use on another variant that have 2gb?.
I've read somewhere that SD600 series can handle up to either 6 or 8 gb of RAM, I not entirely sure, while 800 series up to 16gb
If the ram is embedded in the SoC so it means that there are sd617 with 6 or 8gb available, can one solder that on the phone?
If the ram is separated, can one buy larger modules and manually upgrade them?

The second one is interesting.
It means it is possible.
Now I wonder if it's possible to use another CPU model.
Like if the same series would work or even totally different series.
If it would require drivers and etc.

Theorectically, I imagine only the same series of chips would work, given the motherboard traces and layout are likely specific to the SD 617. Micro-soldering on a different SoC to the Moto G4 motherboard, therefore, is gonna be very difficult/impossible. As you mentioned, that's before you even consider the firmware needed...
