The front-facing camera should have a slight angle downward when holding the phone vertically. This is to assist the camera to focus on your face. however, you only really notice the angle of the camera when you hold the phone horizontally. The same engineering is present on multiple laptops with build in webcams.

I can't speak to the other issues that you're experiencing.
[EVO 4G General] Hrshycro:
I know it's tilted, like you said, but mine is actually off center towards the right of the hole, which is not seen on any of the other 6 evos my friends and family have. One other person on a different forum said that they had the same off centerness and vibration from the speaker.
[HD2 General] dvigue:
forgive me if this has been said before...

i have been having major battery issues on all roms. i have installed most of them and tried all the different radios etc..my battery life would drop about 15 percent in an hour in stand by mode, and would drain really fast if i used it at all....also the os would be very laggy, and i was JUST about to put it on craigslist then i decided to take all my pictures, cabs etc.. of my memory card, and format the whole thing. WOW what a difference, night and day, i am on the new 9.0 Elacancia ROM, and i am living it. runs perfect, i have not used my nexus one since i did this...NO lag what so ever, and my battery life is AMAZING now...im on the brand new radio listed in the radio section

so, if you have any of those issues, format your SD card..works wonders..again, sorry if this is already known. just thought i would share..

trying to get mine to look like the evo 4g.
[HD2 General] barronedson:
ima try this later , ill update after ive used it for a while. :)
[HD2 General] dvigue:
great! i hope this helps some people...i know i live my hd2 so much more right now
[HD2 General] ProjektFuze:
not exactly quite sure what it is that you're experiencing.. BUT.... i highly doubt that it had ANYTHING to do with your battery life... this statement comes from 2 sources.... common sense, and software development....

think of it like this....

your sd card is simply a storage medium... it contains data that is used in conjunction with your mobile device.... in order for you sd card to actually "increase" your battery life or even OS performance... it would have to somehow power your device electronically in order to have any type of effect at all....

like i stated before... not quite sure what it is that you're experiencing.. and i fully understand that the battery issue with our HD2 can be a little frustrating and can/will ultimately lead to the "placebo" effect which occurs in a lot of the "performance" mods that have surfaced here on XDA....

unfortunately the best way to increase your battery life is to minimize usage... (which is retarded.... why should i buy a phone and not be able to utilize every single function available..???) or get a extended battery....

end/

on a side note though... what bothers me the most.. is that with the EVO 4G release.. it came stock with a 1500mh battery capacity... and there are ALREADY extended batteries for the device.. (WITHOUT having to have a stupid huge back cover)... this is extremely irritating at how no one seems to be able to develop a 1500mh standard size battery for our HD2.. when the EVO and HD2 are actually quite similar in dimension... thus the battery size itself is similar... this is mind boggling...

enjoy the lesson
[HD2 General] ProjektFuze:
ah yes.. and my buddy ken.. enter lame reply here..... ouche....... d ccheers
[HD2 General] samsamuel:
sd cards and how you use them can have quite an effect on battery.

by default the 2gb or lower ones come formatted FAT not FAT32, so they are a little less inefficient in read write

the block size that the sd card is formatted in can have a big effect on battery life. Say for instance 2k block size vs 4k block size, in a 2k block sd card you need to perform twice as many read operations than a 4k formatted card. The downside of increasing blocksize is more wasted overhead.

If you are using your card for mostly music and images, (i.e larger files), you can increase the block size significantly, right up to 16k, i would say. That way each read operation takes in 16k, 4 times less reads than 4k, 8 times less than 2k.

Plus, if you install a lot of your apps to the sd card, it will be pretty much running all the time, so the phone is powering three memory chips, rom, ram and sd, and the sd flash chip is more power hungry than the built in flash chips.

If you further have an app running from sd, and an mp3 playing from sd, and m,aybe the opera cache on sd like many have, you can probably hold your breath longer than 1% will last.
[HD2 General] ~~Tito~~:
Ive been experiencing this too. I am backing up my SD now, and about to format to fat32. Twice.

Got this advice from Laurentis26 last night :).

EDIT:

Formatted to 16k, now loading up my backup.
[HD2 General] glcK23:
And the verdict is?
[HD2 General] speoples20:
I have heard some people reporting improvements after reformatting their SDCard. Though anyone formatting their SDCard make sure you back up your damn Transformers movies so you don't loose them, no one here can give them back to you.

One other thing I have found that helps is install all your apps on the phone instead of the SDCard. For me that has improved the overall performance.
[HD2 General] dvigue:
sorry, but no lesson there...

love how some people talk down to other here...
[HD2 General] dvigue:
Thank you for that. Great info. i 100% agree. maybe you should give the guy above a "lesson".. :D

thanks!
[HD2 General] ~~Tito~~:
I had to go to the Doctor's and bandage up my nail on my index finger because I pulled it out when I was leaving my house yesterday. It was part ways out and its not too bad. Anyways going to do a fresh flash, fresh install of stuff using 32k formatted 16gb SD card. Going to be using Laurentis26's rom again.
[HD2 General] PoisonWolf:
Do let us know how it works at 16k blocks.

Cheers.

EDIT: By the way, how are you flashing your SD card? Are you using a proper SD-CARD formatter program? I think Panasonic has a program called Panasonic SD Card Formatter which is designed specifically for SD cards.
[HD2 General] speoples20:
I've never had any issues with the Windows format tool. I think that works just as good.
[HD2 General] Moschdog:
Suggestion isn't completely wrong

I don't believe anyone should come to a fast conclusion (those coming with "2" sources), until all scenarios are accounted for.

1) The more you run apps off of the card, a correctly formatted card will result in less energy consumption.

2) The HTC does seem to cache certain items on the card during usage, again formatting will affect read/write performance.

3) Consider the current war of "new" SSD drives. One of the primary factors driving performance is the block size and efficient use of data organization, to a point of very significant gains.

Logically, the way I see it, for any reduction in processing time, the more efficient battery use will be. Now to what extent, I'm not sure.

One thing I do know for certain is, loud mouthed people, who think quick and talk load are often laughed at by those who think first and talk later.

I just formatted my card as well, to FAT 32, with a block size of 16. Unfortunately, I can't compare, because I'm now running Energy's MaxSense ROM, so apple's to oranges. For what it's worth, I'm really happy with it. It's the first time I've ever flashed something, and it took me all of 30 minutes. Easy to do, only a few quick steps and such an improvement in general. A few bugs, especially when dealing with screen rotation between apps. Yet it's a welcomed trade off, considering functionality.

Got off track... Any way, I appreciate this thread! Even if you are/are not correct, this is a

forum

, built for discussion.
[HD2 General] ProjektFuze:
is there a way that the members here can refrain from senseless remarks? you can believe anything you want.. but that's not the argument... the discussion is about facts... and the fact is... formatting your sd card will NOT increase your battery life... before i was just informing but now... I'm actually surprised at how many people refuse to listen to facts and evidence... since I'm sure none have the abilities to replicate some actual testing like myself... just do a simple search... in Yahoo! or Google.. this is a common misconception and I'm merely informing....

again, believe what you want... proceed how you need to... but don't pretend like i don't have the slightest clue of what I'm talking about because that is just incorrect.... just let opinions be opinions and facts be facts... only internet tards confuse the 2... understand?

once again.. lesson learned.... class is dismissed
[HD2 General] dvigue:
well said!
[HD2 General] dvigue:
well..sorry..but it did....

class is back in session
[HD2 General] Phantoms:
Ahh, the internet has spoken so it must be truth.

I can see battery use going down some by formatting a SD card. But it's not the formatting that would fix anything, it's removing all the installed apps from that SD card as a result of formatting. Especially any apps that periodically check things in the background and make reads/writes from the SD card. The more of these types of apps installed on a SD card and the more apps in general installed on a SD card being removed by formatting, the less battery draw from running those apps.

But do realize, as soon as you put all that stuff back on your right back to where you started.
[HD2 General] barronedson:
hmm battery life doesnt seem too diffrent but the music loads sooo much faster now!
[HD2 General] dvigue:
yeah, all i was trying to do is let people know what helped "me" ALL i did was format my sd card and put everything back..my battery life is so much better.

thats all i am saying..

thanks to all who left positive comments..
[HD2 General] sears1234:
you can defragment the SD drive too

If your SD is FAT32 format, you can do the further thing to improve the read/write performance:

1. connect your HD2 as a removable card to PC.

2. defragment the SD card.

3. disconnect from PC and reboot the HD2.

I hope you can feel the difference. :D
[HD2 General] dvigue:
i do that as well....Great tip!!!
[HD2 General] tuppaacc:
defragment!? how do you do that and whats that for!?
[HD2 General] :
Reformatted my sd card today ...

I will say, cannot speak to battery life yet, but performance is much better using larger blocksize, I think 32k was what I used, on the 16gb stock sd card ...

Thanks for the tip ....
[HD2 General] :
You are joking right ????

Defragmenting aligns all the files and folders in a contiguous fashion on the drive, giving better access time, does not affect SD/solid state storage as much as it does mechanical hard disk drives but it does help.

Reducing the "distance" and number of seeks a drive has to use to find all of a file.

Defragmenting should be done to your pc on a regular basis, most newer MS os's have it scheduled at some point by default ...

Just a standard housekeeping tool for data storage devices ....
[HD2 General] isharma:
I know how to defrag my pc, BUT how do I defrag just the SD card?
[HD2 General] sirphunkee:
When the phone is connected to your PC in disk drive mode, right-click on the card in your desktop windows explorer, choose "properties", then the "tools" tab. You'll find the button you need there.
[HD2 General] isharma:
Thank you very much :) I've never tried the disk drive opt. interesting!
[HD2 General] BerMM:
Actually, formatting your SD card can have a positive effect on both battery life and performance. This is because very little processor time and battery power is wasted when reading an empty card (the card remains powered down when not being accessed). I also suspect that Sense is pretty inefficient about accessing the card. This also explains why such big and generalized performance gains are seen when upgrading to a faster card.
[HD2 General] BerMM:
I agree about suggesting Google, though I'm certain that the FACT is that it WILL increase performance and battery life since I've had 5 different HTC WinMo models with SD slots and this has held true for all of them. Given this FACT, I would really consider changing the rest of that post if I were you.
[HD2 General] BerMM:
This is true, but it should rarely, if ever, be done on memory cards. The cells in memory cards are limited to a finite amount of writes, and all cards have a certain amount of extra cells in reserve to replace those that go bad early. The process of defragmentation involves a great deal of writes and rewrites to nearly every occupied cell, so it is not recommended on memory cards as it will increase the likelihood of the card prematurely failing. Hard drives can withstand many, many times the number of writes, so defragmenting is recommended for them.

In addition, there should be little need to defragment a memory card. The reason that data is jumbled on hard drives is because the drive splits files into bits and puts each bit into the first available spot that passes under the read/write head, resulting in pieces of the file being distributed to random places on the drives platter. This does not happen on memory cards, by design they write in a contiguous fashion.

If you must defragment, it is recommended that you copy all data from the card to your PC and then "quick format" the card. The process of copying the data back to the now empty card writes it in a contiguous, orderly fashion. This method reduces the number of writes from several per cell to one per cell. It also does one large write which is less damaging.
[HD2 General] dvigue:
well spoken:D
[HD2 General] :
So Very True ......

A fact that is sometimes forgotten ...
[HD2 General] echardcore:
How does one go about specifying the block size of the format? When I use My Computer and right click on drive and select format, it only gives me a default allocation size. I can't change it. There are no other options in the dropdown.
[HD2 General] jas0nw0ng:
Ok, I am trying to understand this. By increasing block size (is it equivalent to allocation unit size?), you decrease the number of read operations which can potentially increase battery life. For example 16k takes 4x less than 4k. So if this is the case, when I was formatting my sd card, I had the option of 128k, which is 8x less than 16k. Obviously, it isn't as simple as this (if it was, you all would have stated this already). So my questions are, why isnt 128k ideal? What is the optimal block size?

I am using the 16gb sd card that was provided when I bought the HD2 from T-mobile.

Is it possible to have the above mentioned keyboard mods together at the same time? As far as I can tell only one can be chosen at a time.

[Desire General] deletarus:
I'm also very interested in this. Mainly, I HATE the predictive text in swype. I love the HTC_ime mod keyboard, but the swype is very convenient...

Any chance of this at some point?
[Desire General] K900:
Generally, no. Both HTC IME and Swype are closed source and probably patent protected. Adding such functionality to HTC IME will not be possible without sources.

hi, if you are taking about the sense task bar this is an option in the cht editor under misc, if you are talking about the windows task bar, this can only be hidden in MAX MANILLA, it is not a feature with Cookie
[HD2 General] dvigue:
yes, i am looking to hide the windows bottem task bar. will max manilla work with my tmo hd2? will it change everything or can i just change that? can it be used with cookies home tab also?
[HD2 General] stoolzo:
cookie doesnt have the option and you may have problems removing cookie and installing MAX. You will probably have to reflash with a ROM that has MAX onboard or a clean rom with neither onboard and then install it from there. I have tried maxmanilla on the HD2 yet, I was using it on my old Touch HD and it was smooth and quick, should be a lot better on the HD2.

try flashing the maxmanilla version of the Elegancia ROM, its a very good ROM, be sure you update your radio and HSPL first though.

has anyone found sweetspots with lowmemkiller yet? def want to get this going again - according to os monitor i had 112 processes opened earlier with 80%+ of the cpu being used after using it for the day. Seemed to be going to old games i just carelessly didnt exit out of and forgot about. Im all for letting memory fill up for faster access and all that good stuff, and i dont want to go back to using a task manager app but i have a feeling i could save a bit of battery as these processes were eating cpu.

a good explination of lowmemkiller numbers - http://xdaforums.com/showpost.php?p=5453800&postcount=19

evo has 403,800K ram for apps if im reading this all right.

stock evo settings are

echo "3584,4096,6144,7168,7680,8192" >/sys/module/lowmemorykiller/parameters/minfree

so does this make sense to kill backround apps and all at when memory drops below 150 mb ?

echo "3584,4096,6144,38400,38912,39424" >/sys/module/lowmemorykiller/parameters/minfree

at 250 itd be:

echo "3584,4096,6144,64000,64512,65024" >/sys/module/lowmemorykiller/parameters/minfree

and a more relaxed would be killing providers at a higher rate and backroudn apps at lower? Maybe:

echo "3584,4096,6144,38400,56320,58880" >/sys/module/lowmemorykiller/parameters/minfree

for reference on hero these settings commonly used:

lowmemkiller default - 1536,2048,4096,5120,5632,6144
lowmemkiller less aggressive - 1536,2048,4096,5120,15360,23040
lowmemkiller more aggressive- 1536,3072,4096,21000,23000,25000
[EVO 4G General] Yay 4 Juggs:
i like the idea in place of a TM but can it be controlled to only kill in sequence? start with bg processes(user mandated)...then work on providers(again user mandated) leaving focus app and its dependencies alone as opposed to a kill all? Or is it that with android and sense there are far too many dependencies within each process/app? Just a thought to help move this along...does seem to have > potential vs a TM

[HD2 Accessories] dharvey4651:
All I can really say is "Wow". That's kinda crazy. I mean if it was detachable then that would be one thing but it looks like it takes the place of the standard bezel and uses the sticky tape to attach. No more putting the phone in your pocket or hip case at this point.

uhhm it is detachable! lol its connected using MAGNET or its magnetic :) i just want to knwo if it would fit for the HD2.

Macro lens provides better pictures for close up shots right?

Does this count? Lawl. It's a weird thing that I've obtained either from a broken microscope or something or from some camera. I found it laying around the house so I can't really remember where I got it from. All I know, this baby + any camera = excellent shots. The second picture is a close up of the cloth it was originally sitting on.
