HD2 Issues

i think the HD2 is an amazing piece of hardware and its clearly better than any other competing product in the coming few months. i do however hate a few things about it:
1-the lack of front camera for 3G video calls. while i may not care a lot about video calls i imagine that many will be missing it.
2-i see no point of releasing a separate delayed hardware revision for US market. especially when you consider that the rest of the world version lacks the front camera just like every other US phone. the Acer F1(another 1 GHZ 3G phone) has been available for a while and it supports US 3G bands on the same hardware and it even has the front camera.
3- considering that its the best multimedia phone made by HTC, its lacking the TV-out and the FM-Radio transmitter and better camera(all of which are supported by the N97)
4- the included 512MB ROM is a joke. i know that it can be expanded with SD card. but extra flash on the device is always useful. the 1.5 year old Omnia had 8/16/24BG+microSD why cant this have it. adding 8 or 16 GB flash costs HTC almost nothing to add
5-lack of stylus: HTC patented the capacitive stylus but they didnt use it. i know the the screen is big enough to be very finger friendly. but its still windows mobile and some applications work need stylus (for example Pocket artist).
6- lack of hardware buttons (especially camera). i wish the added 2 or 3 buttons on the empty sides. WM will always make use of the hardware buttons
7-despite the very high specs, its still less than the minimum Windows mobile7 specs (which requires Tegra level graphics performance acceleration and bigger than integrated storage ) which means that it will not be
upgradeable to wm7.
8-i dont understand the 320+128MB. the dedicated 128MB for the low performing graphics chip seems pointless to me. if they are going to put all this memory there why didnt they allocate it to program memory.
9- i really love how HTC managed to make the device reasonably small considering the huge 4.3" screen. i still think that its physically too big for many people. the HD was not very pocket friendly and this one is even bigger. i wish the screen was 4.0" or even 3.8". considering their recent improved and more efficient designs, im sure HTC would have been able to even make it friendly for one hand use with a smaller screen.
10- im not too big on the new standard micro-USB connector. they should have at lest included the hard to find mini-USB to micro-USB adapter with it. everybody already has several mini-USB cables/chargers but ive never actually seen a micro USB yet.
11- they increased up the specs (and power usage i would assume) significantly from the first HD but they reduced the battery size from 1350 to 1250mah!!!. luckily the early reports are suggesting "acceptable" battery life

Only thing missing for me on the device is a decent camera. I don't mean HTC standard... I mean the best of Nokia, Samsung & Sony Ericsson. The original HD took terrible pictures and videos. I don't think there is much improvement in this area from previews and videos.
TV-Out would of been great but sadly missing.
I don't care about front camera because I hardly ever use video call.
It's probably more of a business centric device but with such a large screen it could have so easily been the ultimate work and pleasure phone.
I'm leaning towards the Nokia N900 (Linux) but still undecided.

Just some thoughts for your annoyances! (I currently own an Omnia too)

3G has been around for a while with a front video camera, but I can truly say that I don't know a single person that actually uses it. It's a gimmick IMO.
2-i see no point of releasing a separate delayed hardware revision for US market. especially when you consider that the rest of the world version lacks the front camera just like every other US phone. the Acer F1(another 1 GHZ 3G phone) has been available for a while and it supports US 3G bands on the same hardware and it even has the front camera.
I don't see the point either - bit silly if you ask me.
3- considering that its the best multimedia phone made by HTC, its lacking the TV-out and the FM-Radio transmitter and better camera(all of which are supported by the N97)
FM what? It still bedazzles me that people listen to FM radio these days. Surely most people have unlimited internet now and like I just use internet radio. More stations! As for the TV-out, again, I don't see the point really. Personally I use my netbook/laptop/pc for plugging into a tv since they can play HD. I supposed it would be nice if you want to show off photos to friends but then we all have facebook these days anyway For me, not a sore exclusion.
4- the included 512MB ROM is a joke. i know that it can be expanded with SD card. but extra flash on the device is always useful. the 1.5 year old Omnia had 8/16/24BG+microSD why cant this have it. adding 8 or 16 GB flash costs HTC almost nothing to add
I love the additional 8GB of the Omnia, but I guess they have to keep costs down somewhere. I have a 16GB micro SD, but when are 24/32 going to be available? Anyone know?
5-lack of stylus: HTC patented the capacitive stylus but they didnt use it. i know the the screen is big enough to be very finger friendly. but its still windows mobile and some applications work need stylus (for example Pocket artist).
I think you can still use a stylus but you have to set it up to do so (I saw it in another post on here).
6- lack of hardware buttons (especially camera). i wish the added 2 or 3 buttons on the empty sides. WM will always make use of the hardware buttons
There is no excuse for extra buttons down the side, although it makes it a bit more sleek I guess. But it's not like it doesn't take photos, it's just a useablitly thing.
7-despite the very high specs, its still less than the minimum Windows mobile7 specs (which requires Tegra level graphics performance acceleration) which means that it will not be
upgradeable to wm7.
I'm not sure that's right is it? In that original Leo thread in the main board, wasn't it confirmed that it will be upgradable? I think it's remains a bit of an unknown at the moment. That said, will wm7 be complete in 12 months? Given M$'s history of keeping to their planned dates, I doubt it. I think cookers will make it happen anyway and if not, in 12 months it will be upgrade time. Did someone say HD3?!
8-i dont understand the 320+128MB. the dedicated 128MB for the low performing graphics chip seems pointless to me. if they are going to put all this memory there why didnt they allocate it to program memory.
This one I have no idea about. Maybe they have something clever up their sleeves?
9- i really love how HTC managed to make the device reasonably small considering the huge 4.3" screen. i still think that its physically too big for many people. the HD was not very pocket friendly and this one is even bigger. i wish the screen was 4.0" or even 3.8". considering their recent improved and more efficient designs, im sure HTC would have been able to even make it friendly for one hand use with a smaller screen.
Well lets look at the iPhone. It's a huge seller. The HD2 is only a couple of mm's wider and taller so I don't see anyone is going to see it as an issue when they put it in their hands.
10- im not too big on the micro-USB connector. they should have at lest included the hard to find mini-USB adapter with it. everybody already has several mini-USB cables/chargers but ive never actually seen a micro USB yet.
I totally disagree here. It's the new universal format. You won't have seen many yet because devices are JUST beginning to emerge with it (ie Omnia 2). Already it's working because Samsung usually have their own proprietary connector so to see them go universal is a fantastic step in the right direction. It would be blind of HTC not to follow. So yes, bin those old Mini-USB
11- they increased up the specs (and power usage i would assume) significantly from the first HD but they reduced the battery size from 1350 to 1250mah!!!. luckily the early reports are suggesting "acceptable" battery life
I really hope it can last at least one full day of decent usage without the requirement of a charge. Surely they wouldn't make this wonderful device then shoot themselves in the foot??

It is very likely WM7 will be out by mid to late next year. WM8 is already being discussed as I understand it and WM6 and 6.5 have been universally panned (and quite rightly).
So if you purchase the HD2 assuming it will be out of date in less than 10 months then all well but I suspect many will not be happy (including me). I don't mind spending extra bucks now to avoid doubling my investment by having to purchase two devices in the space of 10 months!
Do you have the link to the original "in the original Leo thread in the main board, wasn't it confirmed that it will be upgradable? "

add this to the list:
1. lack of full-fledged graphics drivers (3D)
2. lack of d-pad; or trackball like blackberrys

1) Front Camera - most people don't use them so not a big deal
2) Buy the Acer if you like it (have fun)
3) it has got an FM Radio onboard I believe
4) Memory could be better but its got an SD card so just by a 16gb card.
5) The point is you don't need a stylus - am I missing something. If you wannt a Stylus get an Omnia 2
6) The camera button could have been useful - but nobody knows if one of the front buttons cannot be used. Shall we wait till its been reviewed fully before we slag it off.
7) Its been clearly stated that the specs do not say "Tegra" only. Thats just not true. Makes me laugh that a phone with great 3d potential and dedicated memory like the HD2 is being slagged off for no reason.
8) The screen size is the best part of the phone - it can be used to watch video, surf the net, etc. So it has to be big to fit the screen - not an issue.
9) Micro-USB!! - You mean the defacto standard now.
10) Nobody knows about battery life yet so lets hold fire.
Why are you interested in the phone if non of its main selling points you like?

because despite its "limitations" its still a lot better than the rest now.
take a chill pill dude and try to tone-down the fanboiasm. our nitpicking will make it very easy for HTC to make the HD3 a better device. also by highlighting them so early in its life, it will make easy easy for its users to deal with its potential issues

I haved discovered that it does support WM7http://wmpoweruser.com/?p=7528 states
(QCOM 8k, Nvidia “Tegra” AP15/16* and TI 3430 all meet spec)
Qualcomm 8k = Snapdragon's QSD8xxx-series chips = Qualcomm Snapdragon QSD8250 (which is in the Leo).. so the processor should meet WM7 chassis 1 requirement.
To answer the FM radio question - the answer is YES
http://www.gsmarena.com/htc_hd2-2957.php
I agree with the comments above. There is no such thing as a perfect device but you have got to congratulate HTC on the HD2 being one of the closest to it.

The processor does, but the Chassis 1 spec also specifies at least 1GB of flash (and at least 512mb fast flash).
The HD2 only comes with 512mb internal memory.

By 1GB of flash I believe that means available storage i.e. an SD card
Memory: 256MB+ DRAM, 1G+ Flash (at least 512MB fast flash – 5MB/s unbuffered read @4K block size)
I am not sure what fast flash means but these are minumum specs and doesn't mean the device can't run WM7, it may just lag in certain spots though somehow I doubt this thing will lag even on WM7

Is the specified 65k for the screen a hardware or software limitation? I know Windows Mobile 6.5 only supports 65k effective colors, but when WM 7 launches would the device be able to display more colors?

sure it does . they dont make "65K color display" !

Most mobile phone LCD screens are 262K colours (18-bit). (This includes many of the displays used on phones that are advertised as supporting 24-bit colour.)

Dude theres a difference between FM Receiver and FM Transmitter. A FM Transmitter is important for those who own a car. The FM Transmitter can be used to transmit Music at a certain frequency which can be tuned to in the car using the Cars FM Radio!
The HD2 already has a FM Receiver. It might also support FM Transmission capabilities but that depends on which chip its using.
Video Out is certainly a welcome addon. Showing off Photos on a LCD is way better than telling them to login to Facebook! I for one will surely miss the TV Out.
Inspite of that, I consider these two features to be of very less importance when compared to the other feature set. This is the THE KILLER phone everyone was waiting for!

Prefer Touch HD over HD2
I agree with Grizzly on almost every point he's been making so far. Before I catch the flames too I shall start with a story...
My HP iPAQ was stolen from a payphone booth within one minute where I forgot it at an airport a year ago. This was my first real PDA and I was extraordinarily disappointed. I had racked up a lot of apps on it and and had even made the home screen sexy and easy to use with a few mods. Going from interfacing my custom cycles with the PCR machine (lab work) to playing old favourites like SimCity 2000 in lectures was great!
The next thing I obviously wanted was a PDA PHONE, so I didn't have to use a payphone booth again... so I got the Touch HD when it just came out in Oz from Telstra (who still sell it for $1500 - 215% markup). And it was absolutely perfect. Did everything, well supported by the community, and using it as a phone and an organizer that synced with outlook it worked a charm. Then last month getting a taxi back from the pub, I was left at a busway because the taxi driver who was fresh from India could not find my home as it wasn't on the GPS. Calling another taxi I got mugged for it while I was using it, snatched it from my hand. So now I was faced with having to get a new phone.
I have bought a Touch HD again. You see, the HD2 as fantastic as it is, is half way between being a traditional WM phone and an Android phone. Without the use of a stylus, how can you hand write down meeting notes? How can I use all my legacy games and applications? What's the point of having something a little zippier when the new manilla (which is a bit too busy) is going to be hacked onto the Touch HD anyway and it doesn't have the Tegra for true gaming pwnage or audiophile quality audio or a true camera replacement camera? Also the lack of 3G camera ticks me off too. I can't video call my parents in NZ which although is horrendously expensive, I enjoy doing on birthdays and so on - on special occasions we're often away from our computers.
What I am going to do is stick with my tried and tested HD and see if the HD2 has any advantage over the Dragon before I upgrade. Or even other non-HTC devices (god forbid) should they provide Audio/Graphics advantages. Because really the point of this thing is to replace the need to carry around other devices. Otherwise just get something that is only a phone, right?

I just found this vid, shows the games on it and well there is only 1 teeter! How could they cut solitaire and bubble breaker! What am i gonna waste time with now...

Very much so. HTC an enormous international company dedicated to producing a whole range of phones and mobile devices needs listen to random forum posters who can't even get their facts straight.
I'd like to take the opportunity to thank you for helping make the HD3 into the perfect device, derailing HTC's initial plans of improving the phone by removing the screen entirely and replacing it with a bar of soap. Your factual inaccuracies are making the mobile world a better place.

Since there is no dedicated off/on hardware ringer switch, is there a way to silence the phone while it is locked?

the volume rocker is normally used for something like that

Please spare us your fan-boyish drivel. What I mentioned in the OP are all valid concerns

wouldnt it be nice to put 1ghz processor in blackstone

i was just wondering with so many custom modifications being made to blackstone... in its software department by developers.... why havent we seen someone taking out the 529mhz processor and replacing it with the 1ghz snapdragon processor.... if not tht than something like a 800mhz or 600mhz processor....
and with that increasing ram a bit aswell to say like 512mb

I think they basically did that..........It's called the LEO!

not by htc... i mean by some basement modification.... like someone takes his hd n experiments on it a bit... not goin out and buying a newer model

all the cpus dont have the same nr of pins and located in the same places

Nothing's impossible!!! I'll get Mike Channon to start working on a tutorial toute suite!!! Will you look at his dedication with 3 packs of 3M floppy disks!!!

ACER F1
If you want snap dragon power in a Touch hd format then you want the ACER f1, together with the announcment that XDA is going to start support third party devices it makes this phone start to lok quite interesting as it is much cheaper than the HD2 and a better size in my opinion. The Nexus one is also another alternative if andriod floats you boat, it doesnt flat mine at the moment but it may get better in the not too distant furure.

A 1Ghz processor, and a Tegra graphics chip, and a 10mp camera with 720p video recording, and an AMOLED screen, and multi touchnessness, and...

the tech is there, "they" just dont want to deliver and "ultimate handset, they prefer to trckle out the tech in order that we buy handset after handset after another hoping for that perfect one. Look at the HD2, great handset but no 720p enabled, no TV out, it could have been a monster. maybe next time eh?

quite right, its a numbers game, a perfect device would kill the market.
and as to the question, do you have any idea whats involved in changing hardware in the HD? firstly its a chipset, its not just one chip you stick any chip thats not ment to be in there and it isnt going to work, you would need to change the whole set, that pretty much means your sticking a new PCB in. not even to mention the pin and track layouts.
secondly the software isnt like a computer, you cant swap things and install new drivers, mostly because there are no drivers, the OS is made HTC then build the base platform around the hardware. Back in the day you might have found an old PDA that had two versions one had more RAM perhaps, the spaces on the PCB might be in the cheeper version which aloud you to upgrade the RAM. Those days are gone. take a look at any PDA PCB and you will see several surface mounted ICs on a tiny PCB.

Processor Swapping???

so I have done some research and found nothing on this topic. I may be going on a limb here but I really would like to know if it is at all possible to swap out a CPU from our touch HD phones with another one? not shooting too high for something like a snapdragon, but something a bit faster maybe?!?!?
I know it might sound crazy but its worth the inquiry. It might not even be possible at all, considering the processor might be imbedded into the motherboard.. I really dont know the inside of a smartphone and i would like to maybe clear up things in that area. I have taken apart and built complete laptops, and desktops, but have never thought of modding a smartphone.
What do you guys think? Im very interested in these responses.

its not possible for the processor is soldered in the board and just in case you happen to remove it it might burn the board or just in case you successfully removed it, what processor would you like to put and is it supported by the blackstone board?

well it was just a thought to get some more speed and to test the limits of modifying our phones. Maybe if it fit, I would swap out all together the processor and board from another faster qualcomm setup

Not physically possible.

But you can always overclock your HD.

[Q] HD2 Hardware Mod Thread

I want to start a thread for hardware mods because of two compelling ideas that have arisen:
1) Swapping in the Super LCD of the HD7S into the HD2. Would it be possible to swap this improved screen into an HD2? I love the fact that I can dual boot android and WP7 in HD2 but that device really NEEDS a better screen. From what I can tell, the previous gen HD7 used the same hardware design as the HD2 including the exact same screen, so the HD7S seems like they just swapped in a better display. There are some guides on youtube that show how to replace the HD2 screen, so a modification like this isn't impossible but pretty difficult. Any comments?
2) NFC into the HD2. This didn't seem like a neccessary feature at first, but a post on engadget about using wireless NFC for android devices seems like a compelling option. I am not too sure about this mod though, don't know how hard it would be. I know somebody successfully created a wireless charging system for the Evo (I think) but an NFC system is a completely different ball game.
Post any thoughts or comments on these mods and propose your own mods as well. For the sake of intelligence try not to post mods without having some backup in terms of feasibility of the modification. What I mean is don't say stuff like "Lets put in a slide out keyboard, an SLR camera on the device and add playstation control buttons". Unless of course you legitimately found a way to do such a monstrous mod!!!! =P.

Well what you propose with the changing of the screen would be awesome, I have to say it would be one hell of an accomplishment. But you not only would have the actual physical hardware to contend with, but you have to ask is all other needed components in the HD2 compatible to work with the proposed adopted screen. Another thing will the actual size of the screen and digitizer for the HD7S as far as the thickness of them together. The questions and obstacles would no doubt be numerous if not to many to overcome or to large to overcome.
Then you have the fact that even if you did succeed in getting the screen installed you would have to modify the IPL of the bootloader to even be abale to use it. Plus probably a whole slew of other software related things would have to be modded. But this is XDA after all
Cheers

really cant see the point, the HD2 screen is already very good, well mine is anyway. That being said though I had a new screen fitted by HTC about a month ago and I am sure it is better than the original one.
hmm.

it won't be necessary to build the native NFC to HD2... they are coming with NFC SD cards, it will be pretty easy for us

and nfc sims
http://www.theregister.co.uk/2011/11/16/nfc_sim_again/

Well about screen..
U may have measured the width and height. And may be same. But what about depth? And what about position of the flux cable?
Thats a hardware thing.what about software? And the display driver section? More/ less volts to backlight leds, display ram and the display itself? Any way give a try..
About nfc.. yap we got the software in every android os for it. Coz all or most of them are ports from phones having nfc( i think so)
But from the hardwre view.. its about making a radio module whith accelerometer support.. and its should be tiniy enough to put into the phone.. so its a realy hard thing..
The wireless charging dock is a simple one.. connecting both through the old technology.. mutual induction. Old wine in new bottle.+ unwanted losses too.+ dustortion to sensitive devices. Well that might be helpfull if u hav a 100% sealed device( water,dust... etc. Proof) and with out connectors which opens the inside world to the outside world!!! For charging a device like dat u can use wireless electricity. Or what else it may be usefull? Its a pure analog circuit. Every dude with a little electronics knowledge can rip a normal stepdown transformer and can make it.
But nfc is not that.. u may get the point..

hardware upgrade for smartphone?

hi there
just wanna know if it is possible or not to upgrade smartphone hardware like in desktop computer... etc ?
thx devs

With the exception of Project Ara, no. The reason for this is because, as smartphones are designed to be light on space, and extremely efficient, almost all of the components are directly soldered to the motherboard, and are so small that they're almost transparent when you look at them from the side. Therefore, until modular phones are available, this is both impossible and impractical.

Yes it actually is,but many people say its not.If you have phone like for example galaxy s 3 and yoy whant to have more ram you can find out ram fot galaxy s 4 and change it.It has the same size but im not sure is any phone service doing that.U can upgrade normal memory with SD card,if you still whant more you can buy bigger SD card.I think that noone needs SD bigger than 8gb

So tell me more, I'm a little skeptical about what you said...
Knowing that the RAM is embedded in the same chip as the CPU and GPU (SoC) (Exynos 4412 4 on SGS3 and Exynos 5410 on SGS4). You are saying that the consumer or a repair shop can remove the 4412 from a his SGS3 and replace it with a 5410? Even if both chips aren't the same architecture? Are they soldered to the motherboard?
Would love to see some references...
U can upgrade normal memory with SD card,if you still whant more you can buy bigger SD card.I think that noone needs SD bigger than 8gb

Yeah obviously, not really an upgrade to the phone memory itself but more like adding on some parallel memory. And not all phones can use sd cards, even some high end phones can't.

Parallel memory isnt possible to add right now,maby it ll be possible for few years but not now :/ That what i said for RAM cant really help you.I said its possible to change ram but not like in home.There are some companies making phones with material you whant (u tell them how much ram and internal nemory you whant,soo its the same phone with changed ram memory) there are some Chinese companies what are doing that i hope you can understand what i was trying to say... Andswer for your first question is No you cant change ram and int mem by your self tell me what ever you whant about hardware and ...other rooting,unbricking things...
Sent from my SM-G355HN using XDA Premium 4 mobile app

so maybe forget about project ara as this phone will not have the design like iPhones... nexus phones with that gorgeous design... etc

My friend i tore up over a dozen android devices in last 6 months . To my suprise no two devices are using anything compatible with another. cleaning up bloatware and excess junk files along with some system tuning and i think youll be Suprised at what these devices can actually do and perform on a 15$ single core 4.0 ics device you can listen to music while downloading more while you browse the web and screen record it all at the same time. unless your trying to do serious graphical gaming on your phone while multitasking i think your good with anything 4. and up. System Tuner Pro rom toolbox pro check it out and enjoy my friend sd read speed has been default 128kb/s on my devices (a must change) Benchmark app hey

Android device are often using SoC solutions. (SoC: System on a Chip)
That means the whole system, CPU, GPU, RAM, wireless networks, bluetooth, Storage, I/O, GPS, Sensors, etc... are all integrated into one single chip. It is that what makes smartphones so efficient in power consumption and size.
There are other support-chips around the main SoC chip, but these usually handle lesser functions such as extra storage space, USB on the Go functionality etc...

HI,
so, maybe is it possible to install a more powerfull camera module on a device like Htc One S?
For exapmle a front camera (from HTC One Mini) of 2Mpx instead of 0,3mpx camera of Htc One S.
Must I port libraries and Api to make it work? Or is it impossible?

Technically it is possible. But practically "doable" I'm not so sure of.
Most android-devices happen to use a common "camera interface" for the camera hardware-module.
But the layout, form factor, connector placement etc can be very different between the various Android models out there.
One cannot simply take a camera module from one model, and fit it inside another. Just the connector itself alone can vary heavily between models, not to mention the "flat flex cable" arrangement.
These reasons alone make it very hard to fit one camera module inside another device.
But let's pretend that one can find a camera module that does fit perfectly inside the phone in question, or that one is skilled enough to perform the modifications needed:
The Linux Kernel module.
Yep. The linux kernel need something too. It's not all plug'n'play with embedded situations such as smartphones. These devices aren't built for plug'n'play in mind. They are statically built. Once compiled, it's snug as a glove. Nothing more, nothing less.
But it's not all darkness around. Luckily the linux kernel is open source. Even when it comes to Android devices.
One can simply download the linux kernel source from the manufacturers web site, and import it to the Android Development Environment that one has prepared for this.
Next thing to fetch is the source code for the new camera module. This can be quite tricky, and is a show-stopper in many cases. Manufacturers often refuse to release these sources, and Android open source world end up with a "crippled state" for the module in question. Blame the hardware manufacturers for this.
But let's pretend that one have a camera module that happen to have its kernel driver "open source". Then one only need to download these sources, and patch them in.
Once the linux kernel has been patched, and the new camera module is available in the linux kernel configuration, one only need to enable it as a "module", and compile it.
Once compiled, one will end up with a "camera_module.ko".
This particular ko-file is what one need to transfer to the Android device in question, and tell Android init to load it.
Now... it should work... but it rarely does in real life. As you mention, there might be some special API and other stuff needed for the software in order to access the camera.
Once again: read the documentation for the camera module in question, and hope that the manufacturer of the camera module have used a commonly used API, and not a proprietary one.
That is enough of me babbling on about this. This is not supposed to be "absolute facts". These lines written are more meant as a general pointer of "what to expect if one tries".
Maybe someone else, more experienced in these matters, can shed some more light on this. I could be wrong.

Great Explanation! Thank You a lot! I think that is not in my capabilities to do that but.. maybe I'll try when I have some freetime
thank you
