When I take a still picture using my Universal's camera, there is a very long delay from when I press the button to when the picture is actually taken. The picture that appears stationary on the screen is NOT the picture that actually gets taken - there's a delay of at least a second if not two.
This obviously means that my Universal's camera is useless for everything but absolutely stationary objects - I cannot take pictures of people, etc. as they come out blurry, overexposed, or not in the frame at all.
Is this a known issue, or a mis-configuration somewhere, or what?
I have the Vodafone V1640, with Vodafone firmware R=1.09.00, G=42.42.P8, D=1.30.93 WWE
Sounds normal to me! I haven't used my camra in over 6 months now, it's awful.
I suffer from the same problem - its f=dreadful but I dont use the camera much anyway.

Hi,
Some obvious things to check:
1. Make sure images are saved to main memory and not storage card.
2. I always find that the Auto setting take the pictures quicker than any other setting. For example at night - Auto takes the pic and saves within 1-2 secs, the night setting probably takes 3-5 secs.
I find the camera pretty good (as an addon not for normal use) and have just learnt to live with its short comings - 1-2 sec delay of taking a picture being one of them.

Same thing bugged the hell out of me until I found this linked elsewhere on the forum:
CoolCamera
It's a load more responsive than the built in camera and you can set it up to work in exactly the same way. Technically it's a trial, beta version but the only trial limitations are in video and repeating shots. The generic camera functionality is all there and it never seems to expire.
Well worth the download.
Hi
I have now had my Universal for almost a year. It will soon be time to upgrade. Seems to be no sign of a Universal-2 - perhaps HTC will not bother, I have no idea how popular they were.
The Tytn comes the closest, but has a very small keyboard with no dedicated number keys, its only QVGA and it does not have a full sized SD-Slot.
I like the form factor of my universal, and can handle another phone of the same size/weight. I would prefer it to be narrower across-ways at the expense, perhaps of being a little longer. Here's my wishlist:
- 800x480 widescreen display
- External display (b/w fine) showing time, name of caller etc etc
- Retain full sized SD slot
- GPS built in
- HSDPA
- More sturdy hinge design
- Better battery life
- More sturdy (click-in-click out) stylus hole (like Psion Series 5 please)
- Hardware 'OK' button
- Jog dial like Tytn, and loose the daft hardware volume control
- Have the backlight button do something useful instead (turn on camera LED for use as a torch for instance
- Instant ring from standby when someone calls
- Access to SIM card without having to remove battery, or dual sim holder and option within OS to switch sims.
- White LCD backlight rather than flourescent aka Sony T3XP (better batt life)
- Modern, efficient Samsung processor
- More memory - ideally 256MB to save installing to SD card
- 802.11G wifi or even WiMax if delayed that long!
- 6MPix camera with digital zoom controlled by jog dial giving 2Mpix image at 3x zoom.
- Ditch the aerial holes on the spine - nothing was ever made available that used them.
- Light up the pickup/hangup buttons on the spine when unit closed and call recieved.
- Appear as flash disk when connected to PC without activesync running
- Retain full sized headphone socket
- Sould not require 6 months of firmware updates before it becomes usable
- Drop stereo speakers on front & IrDA if nessesary to house stuff above in compact package
Anyone else got things to add?!

I've noticed sometimes my Camera stops working - and shows a blank screen when I load it up, no matter which camera I choose (front or rear). Haven't quite worked out why it does it - as it appears to be very random!
I can confirm the 'bug' has remained through multiple hard resets - and appears to have something to do with savings photos to a Memory card.
Regardless, if the camera stops working and brings up a blank screen saying "Can not capture from Image Device" - it always seems to be fine after a reboot.
Has anyone else had a similar experience? If so - any particular conditions surrounding the issue, or has it been equally random for you?
ON a side note... Are there any imaging applications out there capable of attaining FULL, HIGH RESOLUTION video using the Ameo?
I can't seem to get any of the programs working, they all seem to throw up errors when trying to capture, or don't even start.
I like the idea of recording 640x480 video from the 3.0 Megapixel camera to the 8GB microdrive. MUCH fun to be had there!!
Hi all.
This has been bugging me for a while.
Does the xperia actually have a accelerometer?
Don't see it mentioned in the white papers or previews.
as far as i know it dont
as you say it's not mentioned and the
prerelease version people have
been reviewing dont seem to
i'd like an accelerometer myself but also the option to turn it off
AFAIK it does.
I'm 95% sure it doesn't. Atleast not the one i've been using.
Didn't the early prototype vids show it having one?
Maybe I'm just thinking of the Diamond...idk
It switches to landscape when you open the keyboard. Otherwise, the pre-release doesn't have an accelerometer.
I used to have a link, but cannot find it anymore, But back when it was announced, there was a video shot with one of SE reps showing off the phone. (i know, there were hundreds!)
At that time he was distinctly talking about the X1 using the front facing cam to pick up and recognise gesture controls. I have since seen a press release(again, lost, sorry, but try ESATO or SENSE) that SE were dealing with a company who specialise in that line of things.
What i do find odd, maybe just my ignorance, is that as similar as HTC Touch Pro, and X1 are internally, how SE did not have the accelerometer installed. Surely it would only add a small amount to the total cost of the phone?
Yeah, even for a consumer to buy a cheap acceleromenter is only like $1, lol
I've got a very technical, but very elemental question on this subject, please forgive me for being such a nerd.
What do I ultimately need an accelerometer for in a phone?
How does this accelerometer function work anyway?
In laptops I can understand it's function to protect the hard drive.
As soon as it detects high accelerations (i.e. "free fall" --> acceleration of 9.81m/s^2 = 1g) it shuts down all moving parts in anticipation of an imminent impact (which because of the sudden stop results in massive accelerations around 1500g and more).
Easy physics, no mystery there...
But in mobile phones an accelerometer is often mentioned in relation to automatically rotating screens and of course apple's famous ball-through-labyrinth-game.
Technically an accelerometer on its own cannot do that. All you get from this device is a statement like
"The velocity of rotation around the phone's z-axis is increasing by 3 rad/square-second."
so in order to know the phone's orientation from that you'd need
1. initial calibration (i.e. tell the phone where "down" and "stop" is every time you turn it on)
2. constant measurement of acceleration on all 6 spacial axes (miss one move and your calibration is off).
As far as I can tell there's no note in the iPhone's Manual saying you may only turn it on when it's sitting on a stationary horizontal surface (so much for initial calibration).
And I can imagine the electronics reading the accelerometer go into a low-power "alarming amplitude only" state too most of the time to preserve battery power. Also you'd have to consider the Earth's rotation and path in that calculation too, since the measurement is rather absolute.
Besides, there are more simple and reliable methods out there to to create an artificial horizon (gravity sensor), so what's the benefit of using an accelerometer in the first place?
So, how do these Phones really know where "down" is to auto-rotate my screen if they use an accelerometer, and why not use something simpler?
The only benefit I see is for car navigation software to use the sensor when the GPS signal vanishes (in tunnels etc.) to extrapolate your course from the last confirmed position and velocity, but as far as I know they don't even use it (yet).
Ok, let's say either:
A) you have a slight factory calibration so it can "guess" which direction.
B) it dynamically calibrates as the phone is held/moved/twisted.
C) It's not near perfect, just a guesstimate of movement.
and
it's just for screen rotation and games
dont believe gps's use it as it's not precise enough
Let me apologize first, because, I know nothing about all that disertation about accelerometers. But let me have my street guy comon sense opinion.
First I don't think these phones have such a sofistcated type of accelerometer. The use of the accelerometer word in mobile phones is a missnomer because I'm sure they have something simpler that I would call it "Balancerometer"
I believe it's just 2 or 3 tubular circles perpendicular to each other. These tiny tubes are filled with some kind of liquid The reading of the position of these liquid is enough to know the position of the device ex: Vertical, horizontal, diagonal at any angle of mesurement. It probably cost no more than $2.00 in mass production.
You know better tha me. Do you think I am crazy or worst?
GSM Arena says
Size 800 x 480 pixels, 3.0 inches
- Full QWERTY keyboard

But then again ... who knows.
In the diamond app forum, Ikari creatied pocket gforce which from the picture, its not just a simple tilt sensor. Even I wonder why we need the full thing.
But cool though.
x1_wp_r3a.pdf manual
I have the manual above. Not sure where I got it from .... but it doesn't mention accelerometer and it is SEs own May 08 X1 whitepaper.

3.2-megapixel camera and video call camera
There are two cameras. The main camera is 3.2 megapixel and includes Touch auto focus. A picture can be shared with friends or family, as a picture message or e-mail, or using any available transfer method, such as Bluetooth™. There is also a QCIF camera, for video calls, located on the front.
Photo light
When lighting conditions are poor, pictures can be enhanced by turning on the Photo light.
Video capture
The camera also records video and which are stored in the phone or on a memory card. A video clip can be shared with friends or family as a picture message or e-mail, or using any available transfer method, such as Bluetooth™. The phone supports VGA size video recording at up to 30 frames per second.
•MPEG-4: 30fps at VGA*
•H.263: 30fps at VGA*
•H.264: 15fps at VGA*
Can forward on to people if they want it ....
I do struggle that so many people are worried about WVGA. The G900 ran all the s/w I have without issues including Softmaker Office, CPL6, PI, FM, Pie+ etc ... WVGA is real extra screen estate rather than just VGA prettiness.
I know only time will tell, but this has to be leagues ahead of the Pro.
It is only the price that scares me ... and the fact that there are still performance issues with video at 30fps .... which as you can see from the above is a biggie for me.
The only daft thing missing I can see is the TV-Out ...

These accelerometers actually measure the Earth's gravity also. It constantly measures the 1g with which the Earth is pulling the phone. A 3-axis accelerometer gives you the projection of the gravity vector on each axis (x, y, z). Assuming that the phone is only rotating (and not translating), it is easy to find to where the phone is facing... for example, if the x and y acceleration is ~0 and z is ~1, then the phone is facing up, like leaving it on a table top. If x=1, y=0, z=0 => phone in landscape. If x=0, y=1, z=0 => phone in portait mode.
When the phone is being translated (moving, that is) in a non-constant manner, a "dynamic" acceleration vector is added to the 1g Earth's vector. In that case, calculating the phone's position/rotation becomes more tricky and more erroneous...

Actually, in free-fall, the acceleration is reported as zero.
Even ipod nanos come with accelerometers now. Don't sit well with me if the xperia doesn't.
Well, even the C905 and G705 have accelerometers, so why couldn't SE put one into their flagship

Years ago I used to think alot of debives measured that way, at one time it may have been like that but not now.
http://en.wikipedia.org/wiki/Piezoelectric_accelerometer
I have an RC Helicopter and a strong interest in electronics...so yeah, I just happen to know random stuff like this, lol.
They manufacture these in bulk as chips often...some even having 3+ (rotation) axi on the same chip.
Even at retail you can get the raw high-end chips for a couple bucks...imagine how much they cost in bulk.

Got my TD2 yesterday, still have my TD1 (until I sell it) here sre some comparisons:-
1) Unboxing
TD2 is in a much cheaper pack than TD1 simple outer box with simple inner "egg carton" tray, gone are the shiny cherger and usb cables to be replaced with functional but plain matte black ones.
2) Build quality
I would say about the same although the TD2 feels more solid in the hand to me
3) Radio
TD1 with latest official WWE ROM versus TD2 with ROM 1.39.405.2 (47382) WWE Radio 3.43.25.19 as I look at both devices in front of me both are showing 2 bars.
4) Interface responsiveness
Finger control is smoother and more responsive on TD2, interface feels faster. No lag any more when exiting Opera.
5) New Tabs
Stock Tab is nice deeper integration of TF3D (e.g. in calendar) is cool
6) Internet
Push web is a useful feature and it is easy to control how often pages update
7) People Centric communication
VERY useful (to me at least) only had the thing 24 hours and already used this feature several times!!!
8) Music performance
Have listened to about 1 hour of music with NO SKIPS, supplied headphones are adequate, device speaker is loud and clear
9) Video
The film "V" plays without skipping or stuttering at 927 kbps and 25 fps (which is how I encoded it). Don't know whether that is regarded as good or bad but it impressed me!!
10) Battery life
Not enough time to give a defintive opinion but seems good so far
In summary the TD2 is an evolution rather than a revolution, but if your TD1 is getting a little battered and tired and you have some spare cash, I would recommend the upgrade!
I think it’s just straight common sense especially if you are a Touch Diamon1 user you buy the phone because of the size and its fully packed with great hard/software, and if there’s a new model almost the same but a little bigger but much faster and nicer it’s just common sense that you are going to upgrade to a Diamond2.
But I have to say the Pro2 really did get my attention. But still the Diamond2 won! Cant wait till tomorrow.

Does the HD 's 3.5mm jack works as MIC as well?
I just use the diamond with a 3.5 adapter with MIC, handy when there's incoming calls.
About the TD2 , is the stylus got magnatic ends like the TD1 / T PRO / HD? and pull out stylus turn on the screen?
Does TD2 use MSM7201A? and no 5-minutes lag with speakers or wire headset when using music softwares other than TouchFLO3d / WMP (eg: core player / TCPMP / pocket mucic / pocket player)
Can it be use in landscape mode for 3rd party software without regedit?
The TD1 cannot rotate screen other than opera/album, and HTC support will yell at you complain about touchflo3d / phone pad / incoming calls not working in landscape mode.
Can it play RMVB files like the SAMSUNG OMNIA?
When you press CALL button , the phone pad will pop up with last few call history, in the TD1, there are some left and right arrows on the right side of the number for you to choose between mobile / text / work / home / email , it ONLY works with the D-pad in the TD1 . How to toggle between mobile / text / work / home / email in TD2 ?
Does the zoom bar work in most software?
How about the BACK buttons? is it as useless as the one on TD1?
Many thanks
To answer some of your questions about the TD2
The stylus is not magnetic, but pulling it out still turns on the screen like the TD1
The device information on my TD2 shows a 7200A fitted - I use core player, I get no lag
Landscape mode is available for Opera, Album, Email and You tube out of the box
No Idea on RMVB files
Pressing the call button still brings up a call history, there is an icon next to each which calls up the contact card for the person, you select home/ mobile/ email etc. from there, the whole process is slick and fast, no lag.
The zoom bar works in camera (video and still image), album, opera, excel and word - maybe others, haven't checked everything!
The back button does what it says on the box...
Hope this helps
how about the RAM usage? on startup and after opening and closing application?
After a soft reset - RAM usage is 37%, if I then open OPERA, navigate to bbc.co.uk and then close opera (completely), RAM usage is 52%. I don't think mine has got beyond 60% at any time so far.

I don't get why people want their PPC to have free RAM not being used all the time. The unit should be bouncing off 95% used as much as it can.

Does word/excel work in landscape mode? Email works in landscape, does it mean SMS/MMS works in landscape too?
When using EMAIL in landscape mode, what happen when there's an incoming call?
Word and Excell do not switch to Landscape, SMS/MMS do not switch to landscape. When on email in landscape, an incoming call results in caller ID being displayed in portrait mode.
One important note, the annoying delay before the phone rings on an incoming call that was present on the TD1 appears to have been eliminated on the TD2

SMS does go into landscape! i tought it also but if you tilt the phone to your left it goes into landscape
This phone rocks! that i even tought about have a full keyboard
I actually liked the TD1. I also have a Nokia 5800 & the wife has a LG Renoir, I tried so hard to like the Nokia but S60 is total ****e.
Anyway only a few things annoyed me about the TD1 most significant being low speaker volume & low memory warnings. After reading the posts here and on a few other sites it seems the TD2 has addressed most of the failings of the TD1 so thats reason enough for me make the upgrade.
i was also a big fan of the original diamond and upgradef mainlu for the official route to wm6.5. i am glad i did, this phone rocks!

And: TD 2 better camera (5 MP), larger screen 3,2" WVGA 480x800, much more memory, micro SD-card, stronger battery.
But also: no select/scroll wheel, remove the backcover to softreset and to get the sd-card in and out, a little bit thicker...
My new baby...
TD2 actually has removable memory. That's a huge plus IMO.

hi christonge, will perform my first tests tomorrow. It feels fast, hopefully it also benchmarks fast...
I'll be back.
fm radio present and correct1
when i compared D1 with D2, i saw that the D1 has a proximity sensor for auto turn-off (when putting it to the ear during a call), and it seems not to be mentioned for the D2.
is it true that the D2 does not have the proximity sensor? so when you call, while putting the phone to your ear/face, you can accidentally press "buttons"?
this would really suck imo... :/
