soo.... i see very little discussion about this.
has anybody here looked into actually porting the iphone os
heres a link to get you going if you havent
http://www.roughlydrafted.com/2007/07/13/iphone-os-x-architecture-the-mach-kernel-and-ram/
i know people say you cant...
hardwares not the same. man i asked a stupid question to fast. sorry. next time i will think.
i just think it would be fun. i probably would not use it very long since it wouldnt be very functional on anything other than its true hardware. since i doubt anybody has the kinda time it would take to get a full working version.
Easiest way to do this is wait till July 11th, save up $199 and go buy an Iphone if you want one that badely!
Unfortunately, because of the different processor architechture, you'd need to basically rebuild the core/kernel...
And, since it's virtually impossible to even get into the kernel, that seems like it could take a long time
The kernel is not part of the software image that crackers have been looking at. Instead, it sits on its own encrypted disk image, which appears to require massive brute force efforts to decrypt. If it is ever unlocked, it will likely have to involve a workaround crack, because it is scrambled with a long enough key that makes simply guessing the password virtually impossible.

That is a typically badly written, lousily research roughly draughted article.
Saying that "other phones are limited to 2gig" and having the N95 with SDHC support there - ie. it can take 4/8/16/32gig as and when they become available.
And so what if the other phones have less memory - they don't need it! Symbian has been designed from the ground up for mobile devices.
Symbian are trying to catch up on functionality???? Where does that load of rubbish come from? The Symbian and iPhone browsers have the same underlying engine, and the S60 browser is about as fully featured as any.

Symbian does hang quite alot (N95 release build for example...)
Also, most devices have SDHC now, which is up to 32 (maybe 64GB soon). And, a large number of WM devices have more RAM than 64MB anyway...
WM has far more functionality than the iPhone OS, and both S60 and WM have developers
And now this thread has turned into yet another iPhone flame

That is partly true my device only supports SDHC cards(even with the hack at this point in time) up to 4gb(if there was a 5gb card that be the max it supports, not even 6gb shows up in full).

I'd guess therefore that your device doesn't have the SDHC hardware (SDHC uses longer address bytes), and has instead had the drivers patched to recognise SDHC cards rather than be truly SDHC compliant.
does the gpu of hd2 is powerful enough to handle directx 9 announced as requirement for wp7
I was wondering the same thing the other day and couldn't find any official spec sheets. I asked over in one of the threads in the WP7s forums and I got the idea that OpenGL ES 2.0 was supported, which was 'basically the same.'
does any one know any useful info
http://brew.qualcomm.com/brew_bnry/pdf/brew_2007/Tech-303_Ligon.pdf
See page 15 for the best tech specs I've seen on the snapdragon / z430 / ATI LT. Still very light on details but claims direct3d sm3 support.
For that specific chipset (MSM7850) they claim DX9 support on page 31.
Their old chip (7500) supports DX7.
Since that was 2007, we can presume they've maintained similar compatibility in their newer (8250) chipset, yes?
Missed that bit, now all we need is a driver </sarcasm> for the humour impaired.
[sarcasm]obviously MS is aiming really high this time..
DX9 compatible portable devices, that use huge amounts of power so they can do what?
render a load of bloody text!
whoopppeee !
[/sarcasm]
so tje final answer is that hd2 gpu is enough for directx 9 or what?
The only correct answer to anything around here is, that noone knows nothing at all!
We can't run DX9 on WMPS7 so what ever?!
Before everyone freaks out, about fckn WMPS7, why not wait until you really see something?
Actually all the previews by microsoft were pretty ****ty! The phones worked pretty slow, I dont like that "hub" thing, and they are limited to the ground!
Thats what I would call "YaI" -> Yet another Iphone...
I'm loving WM6 and the only OS I'll be switching to, if WM6 dies (what i dont think, cuz there are more programmers who like WM6) will be android, but not another limited bull**** os

after reading i think it supports it
HTC reports 32gb microSDHC 2.0 as supported, which *should* allow contiguous fat 32, but some have claimed the phone itself can only format the first (presumed) 16gb.
Further, there is *nothing* released regarding architecture (i.e. SPI and/or 4 bit modes, voltage, min/max read/write speeds, 'n such). Not even which class *may* exceed their capabilities.
Am I the only one upset over this lack of disclosure, or have we all been lulled into submission by this great new device? and, oh, yes, it is kinda great... but I digress.
I need engineering details specific to the HTC Droid Incredible, beyond the marketing strategies and press releases, if anybody's got 'em yet. Much appreciated ...
Not to be so negative or cynical but what are you going to build a phone? Are you trying to get attention? Please explain in detail what you need this info for I am really interested and if its for ANDROID then I won't ask you to move your post. But if this has nothing to do with ANDROID then please do not post in here. Read the title of the section it says Droid Incredible ANDROID development not Droid Incredible Development. Last I checked SD card readers are not specific to Android. There is a general section where this could go and live in peace.
That was incredibly hostile.
I think that this is a perfectly valid question, even given that it's in the Development forum.
Maybe Developing a workaround is not to be considered development?
Maybe it just requires some modifications to the related kernel module? In my opinion, that has a lot to do with ANDROID the operating system that you so vehemently barked at him about.

1. We had nine phones at my last count, two of which are Increds, of which mine is reportedly 13th sold locally, so... no, I've no desire to build a phone. And, to 'show off' via the 'net is *almost* as stupid as arguing needlessly w/in forums.
2. Uhmm...No; I'd tell you why, but then they'd kill us both.
(Just kidding) But, anybody that wishes to develop for the droid OS on this Incred I' m poking' the virtual keys on *should* have enough creative thought w/in to think of many reasons: This post is exactly where it belongs.
3. Answered above. But, further, perhaps you should consider my questions nearly so well as I review forum hierarchies prior to posting them.
4. Uhmm.. remove the cover carefully, and you should find the exact same slot w/in your Incred as I'm considering w/in mine. Now, beyond using cables, there are a number of wireless methods that make cards inserted there accessible...
But, my questions remain: What speeds are consistently available for microSDHC read and write in the HTC Android Incredible, and under which conditions were they measured? Is this device capable of SPI and/or 4 bit mode(s)? Can this device format the full 32gb internally, and is the entire volume available?
Now, if you have the answers, I'm anxiously awaiting your response. And, if you don't have the answers, remember that I don't either; just gettin' started here. Either way? Kindly quit peein' all over my post

I'm brand new to this current flavor of OS, beyond following along conceptually, but you're thinkin' about the relationship between devices and the OS/Apps developed to operate/run 'em in the right way ...
I usually get the cheapest tires that will serve my needs, 'cause I'm poor as the dirt I drive on, but wouldn't it be wisest to select a speed/load rating that barely exceeds the limits of the vehicle, and a size/pattern that suits the driving conditions?
Not the best analogy, but ... continuing w/ it anyhow:
If you were really hopin' to tweak performance, then you'd need all the details you could get, like suspension design and torque 'n such.
Not that I'm focused on gaining root, but I suspect the answer would be most easily discovered by those w/ the greatest understanding of exactly what the Snapdragon can do w/in the architecture of the Incred, and every possible detail about Droid 2.1 Linux kernel.
And, the answers to my questions may prove most important to them, too

Lets play nice guys
microsd speed (htc support)
Official position is that class 2 devices are guaranteed, but that the HTC Droid Incredible may exceed class 4 ... no specific details are provided to techs beyond this statement, but response time was INCREDibly fast.

The HTC website lists the external expansion as:
Expansion Slot
microSD™ memory card (SD 2.0 compatible)
Up to 32 GB card support. No pre-installed card.
Click to expand...
Click to collapse
Of course, Verizon is distributing the phone with a 2gb card.
The SD 2.0 standard is listed as (Not on HTC's site):
SD 2.0 offers FAT32 formatting as well as a maximum capacity of 32GB - sizes of 4GB and above are not compatible with existing SD 1.0/1.1 standards. Any SD card that are 4GB and above in capacity will be dubbed SD High Capacity (SDHC), although the transfer rates of the new format maxes out at a paltry 6MB/s.

The classes that are available and supported are defined by the SD Association which defines them as:
Speed Class 2 guarantees a minimum transfer speed of 2 mega bytes per second (MB/s)
Speed Class 4 guarantees a minimum transfer speed of 4 MB/s
Speed Class 6 guarantees a minimum transfer speed of 6 MB/s.

So since HTC has stated the device supports SD 2.0, it is already saying it supports the related standards so it supports up to the defined Class 6 speeds of 6 MB/s which is defined by the standard. That is most likely the only answer you will end up with unless an independent lab does tests and releases that info. I'm sure HTC isn't going to bother defining it more than it simply being SD 2.0 compatible. Not sure I've seen any other mfg do so.
You of course end up with a can of worms with regards to the "source" of the cards you buy, whether they are in fact what they are labeled as etc... There is a lot of forged and fraudulent cards out there.
BTW, up to 32GB support does not mean the device can format that.... just that it supports it. That would be one continuous Fat32 block of space sans the amount you lose when you format any memory device. Not having had the chance to play with one, I'm not sure what that total would be, but I'm sure it is calculable.
Just keep in mind that Class Ratings = Write Speeds. Read Speeds varies by the SD controller card and by the phone's processor. Also I tend to stick with brands more than class ratings and SanDisk has always treated me well whether it's been MicroSDHC Cards or Duo Pro Memory Sticks. Sometimes Kingston's cards are cheaper with more or less the same results. I need to leave the house now but I will post more tonight on the subject if someone doesn't beat me to it =p.
Excellent points, and thank you for your input. Although I follow your logic, I'm not entirely certain that HTC's claim to "support" 2.0 requires they read/write @ full speed.
In regard to card org's standards? I can't afford the required fee to gain access to complete specifications (playin' by the rules can be frustrating, in that I know *exactly* where the pdf I wish most to read resides).
In regard to card quality/performance? I've bookmarked a few programmers' comments, remembering one who discovered a transcend card's failure to properly respond to SPI mode access, despite claiming full compliance.
An aging but still excellent comparison of many SD/sdhc cards w/in a specific NIKON camera is with lookin' at:
http://www.robgalbraith.com/bins/camera_multi_page.asp?cid=6007-9597
I've played w/ a few benchmark tools, but have not found comfort in their findings when measuring two Increds (one w/ microSD, the other w/o) under various, but identical, scenarios. I may have to temporarily focus on building a different app, if I can' t find another way to compile the data req'd.
God knows I can't afford to buy one of each card, just to figure all this out.

Thanks, and so very true ... I've already seen wild variances that seem to depend more upon sizes of file(s) and buffer settings than class ratings. In fact, some slower cards have seemed to outperform their betters under certain conditions, presuming benchmark results prove to be accurate.
Speaking of those memory stick pro duos? I bought all but the last one in stock from each of several local clearance stores (for literally pennies in some cases), w/ the intention of stacking under SPI mode. Still haven't gotten around to it, but our Sony's haven't req'd us to delete pictures for a very long time
For "bang for your buck", I would recommend this SanDisk 16GB MicroSDHC. This is probably the one I will be buying myself, so if you want to wait a week I can give you guys real Incredible performance details. However, be warned that it is a Class 2 device. It seems to have been designed with phones in mind (and specifically mentions working well on HTC devices). Saves you a few $ by not including an SD adapter or USB reader. I was impressed by the speeds noted by the user in their PC configuration, but of course I will keep an eye out for better deals and any proven information.
In some scenarios, I've seen a class 2 sandisk perform better than a class 6 dane-elec, but I'm thinking a bit forward about all this ... lookin' to run (or, at minimum, support) app(s) from the card. And, there may be a few more tricks comin' soon.
Thread moved.
I know the Galaxy S8 supports by default Quick Charge 3.0 but does anyone have a thought onto how if the SD devices (like mine) get root, then get unofficial ROM ports to our devices, do you think in the future it would be possible if the ROMs could support Quick Charge 4.0 natively since the SD 835 is compatible with Quick Charge 4.0? I would love to see that soon in the future.
If anyone can answer this question, that would be greatful.
Thanks!
A chipset natively supporting something and a manufacturer implementing it are two very different things. Samsung would have to design the phone to utilize QC 4.0 which then will take advantage of the native chipset support.
Basically, No. The S8 is not even listed as supporting QC 3.0 in qualcoms website. There's been debates and discussions on other forums and the general consensus is. S8/S8+ only support QC 2.0
Samsung didn't bother adding support
It's not that samsung didn't bother but they didn't pay licenses to Qualcomm because they already paid a lot for sd835 licenses itself and a percentage of every phone sold.
Same goes with updates - if Qualcomm is hostile with updates Samsung will not release those.
Hi,
I'm looking for SD card for my phone, and can find anywhere information about this. Anywhere I'm looking, I only can find information, that it support microSD 128 GB.
I guess, it means that this smartphone does NOT support it, especially that 2015 was year when faster magistral was just introduced (or was it 2014), so maybe they just didn't see reason to inform about something like this... And some new good smarphones doesn't support it either.
But it's my guess. Anyone know for sure? Does buying UHS-II SD card supposedly will make it faster, or limit is on UHS-I?
Thank you for your answers.
