Screen Rotation

Hi All,
I have updated to the latest AKU3 ROMs and also a few months ago I replaced the housing...However, I've noticed that the screen does not automatically rotate when the screen is swivelled??
Now is this because I did something during re-assembly of the housing OR is there something in the ROM's that disables the hardware somehow??
Cheers
ODY

Unlikely to be the rom, since it's part of the system HTC provided.
If it's been disassembled it's more likely that.

hey VJ, sorry to bother but do you know what jumper/cable/connector/switch to jump/disconnect/tape inside the Universal to keep it from switching?

I'm sure I saw someone mention that the screen rotation is done by a magnet and switch? It's possible that maybe a small magnet fell out during disassembly? But I have looked throught the Universal repair manual and I can't find any reference to such a magnet??

I'd be nice to know exactly where it is so one would be able to take it out, if it were easy. I don't know if I wanna disasemble mine yet...
EDIT found it!! If you use a very, very light metal chain, as I did, with a keyring @ end, you can hover it around the Universal and see the tension of the chain when it's near the magnet. the keyring sticks too!
it's on the lid, behind the video-call video camera. I'm going to check the lid part of the manual.

Well taking the screen section apart is easy! You don't have to disassemble the whole unit. Looks like my magnet fell out then! Trouble is I want to sell mine so I'll just have to declare the auto screen rotate doesn't work (I've made sure that there is the rotate screen icon on the task bar though!!)

it works!! I tested it with the very small and highly magnetic point in the bezel of my tablet PC (to hold the pen) and it did change orientation.
thing is that it seems to be stuck beside the sound-holes (when the unit is closed).
I wonder how could I disassemble the lid only? are none of those screws @ the bottom connected to the back part of the lid? if so, that would be awesome!

Hi, on the xda's ftp, you'll find the maintenance manual for Universal...may help you to disassemble yours

thanx for the link!
however, it seems rather risky to try to pry the bezel open while still on the unit. Anyways I'm doing it right know. I'll get back to you.

I did pry it out and took the magnet off... painless(*) procedure and flea-sized magnet! don't loose!
I took a couple of pictures detailing the magnet position and the lid disassembled while still on the unit.
if you want to do this procedure do not loose the tiny screws and...
(*) be careful with the outer speaker (the one that lets you hear a call while the screen is facing the keyboard when closed), it isn't hard wired, it's just two small and fine contacts that might get distorted when putting the lid cover back... I had to take mine out again to correct this problem.
also, be careful with the screw driver and digitizer, as you'll be working in very akward positions to avoid disassembling the whole unit, and take off the battery of course.

Thanks for the photos - looks like my magnet feel out so I bought some 1/8 inch square magnets from ebay. It took a couple to find the sweet spot where the screen rotated but at least it works fibe now!

no problem. I'm also going to put the magnet back, now the unit doesn't now when it's closed, and therefore the outer speaker does not work. the screen also does not turn off when closed, only when the system timer tells it too... oh well.

you can turn the screen off by pressing the power button briefly.
no ext speaker though! maybe there's a way in software to disable just the rotation; i think the guys trying to get linux comfortable on the universal have some experience with it, maybe they can help.

phone casing not flush, can somone compare with theres

Hi all, just recived my replacment handset ive ive just noticed at the bottom the suronding around the mini usb sticks out one side so its not flush with the rest of the phone, im sure on my other handset this wasnt there but not sure for deffenate.
Can anyone confirm this or is it just my phone
Thanks

Mine is the same - I think this is by design.

ok cheers mate, just cant remember it on the last handset

Yep, this is standard. The Use connector housing is square and does not follow the curve of the casing.

Something I have noticed is that on my brand new replacement handset (serial number beginning HT643, my original handset was an HT634) the silver bezel which runs along the right hand side of the screen is recessed slightly - nothing major, but when my original handset's metal strip was flush with the plastic casing, you really do notice it (particularly if you're holding the phone in your left hand). Oh well, only a minor issue really!

BUT maybe this is how they are solving the Screen alignment problem - DONT bend it. Only joking but you never know do you.
Mike

Not planning on it I did notice that JUST as I replaced my handset my screen alignment drifted out, which I corrected with a realignment (I had it replaced for another reason - people not being able to hear me after I'd gone through any call which involved entering numbers to an automated menu system, and then being on hold for a long time! for example... To the T-MOBILE CUSTOMER SERVICES PEOPLE! haha).
Very odd, hope it doesn't happen with this device. I won't go hacking the case to fix it though, I'm too lazy for that.

Thats one of the exact problems with my previous handset but mainly when on speaker phone

Anyone have a problem with part of the touch screen not registering?

I have an HTC hero and I am having problems with the bottom third of the screen. I cannot "click and hold" in order to drag a program icon, for instance. Instead it just registers the click, and not the hold! Very annoying.
I have MoDaCo custom rom 1.5 on it, but don't think this could be a software/firmware issue. I don't recall it being a problem before, so it appears it has developed a fault!
Nightmare. Anyone experienced anything similar and an easy way to fix it?
James

Hi,
I can't actually help you but i can tell you the first iphones would develop a similar problem with their touchscreen where sensitivity dropped off, especially near the edges. This turned out to be a coating wearing off.
This seems to be happening from time to time with capacitive screens.
If you are sure it's a hardware issue, i wouldn't hesitate to send it back.
Kr,
-Kevin

Have you tried re-starting the phone?

Yes, and it made no difference. But pulling the battery and restarting (I had to do this to get theserial number fot HTC support!) worked!!
Cheers
James

You could also download a "Draw" app to test all areas of the screen.
When I first had mine I had problems hitting the Backspace on the portrait keyboard, I tried a calibrate but I think its better now because my finger knows where to go.
I find my screen seems more responsive when the phone is in my hand, less so if lying on a table. Is this a quirk of a capacitve screen or more to do with the angle of attack?

This. It doesn't seem even remotely responsive when I have it lying down flat on any surface, but as soon as I pick it up it works again.

The metal bezel actually acts as a grounding point between the capacitive areas that don't have any adjacent space to get a good contact...

Smart use of Proximity sensor can kill the need for the lock screen

The main need for the lock screen is in the following situation:
Phone is in your pocket (or bag), a hard key is accidentally pressed, the device wakes up. This by itself is not a problem, since without anything else happening the device will go back to sleep, but, if another hard key is pressed while the device is active (screen press can not happen while in pocket, since it's capacitive), the device can start do annoying things.
Now, if the proximity sensor can be designed to switch on when device wakes up, and put it back to sleep (immediately) if device is in pocket/bag, this will kill the need for a lock screen. This is totally possible and just awaits the programmer who wants to make our lives easier...

hm. try pocketShield?
it locks and unlocks your device by use of the light sensor.

Interesting. I will use it for now.
The problem with using a light sensor is that if you use the phone in the dark it won't unlock. Proximity sensor won't have this problem hence it's a better sensor for the task.

Apparently this will happen even without the help of the XDA community...
I've just sent the following email to PocketShield:
Hi,
I would like to know if you are working to utilize the HD2's proximity sensor for unlock (like you did for Omnia). If so, when should we expect a version with this feature ?
Thank you very much.

This is their answer:
That’s the idea, but can’t confirm that yet because we are not sure if hooking into the proximity sensor will be possible. Hope yes, as in Omnia2. Just received our new HD2 today and will start to dive into it next week.
Best Regards,
Jim

Use TouchLockPro. It has both light and proximity sensor and it is free.

won't this increase battery drain dramaticly? i think it will becouse it will be constantly looking for light and using that proximity sensor..

You are wrong about one important detail though. The screen is very sensitive and can easily be pressed through the lining of your pocket, and even through fairly thick fabric like jeans.

it's a capacative screen...
capacative scree = no stylus/fingernail/penny/spoon
it wont be acvitating throught screen contact.
impossible. (unless you have rrrrrealy thin pants, and the current can pass throught them)

hi, the pants didnt have to be that thin. i think the hd2 screens also vary a lot, in being more or less sensitive. another thing is that people are deifferent when it cames to electric fields. also sweating can affect the display. i startet programs and other touchscreen things already, when the device was in my pocket.

In the case of Pocketshield, it won't. Because all sensors only turn on during a short period of time (seconds). Once you unlock or turn off, sensors go to sleep. This is one of the reasons why "auto lock" is not possible, because that will indeed involve a permanent monitoring on the sensors.

You don't know what you're talking about. I didn't say it was sensitive to pressure, but rather that direct contact between skin and the screen is not necessary. Holding my finger on one side of the fabric, and the other side of the fabric touching the screen, this is registered by the screen as a touch EVERY TIME. There are maybe materials that completely isolates the screen, for other materials it probably depends on how thick they are. For me it is certainly possible to influence the screen even through pretty thick cotton fabric (maybe other types of fabric too, I wear mostly cotton), leather, and even paper. Just to test it, I just did a slide to unlock my HD2 through a pile of papers (granted it wasn't a very thick pile, only six sheets of paper thick), and through my leather shoes (this was a little trickier, I had to to make sure that my foot made good contact with the leather at the point where I was sliding my phone across the shoe). i can interact with the screen through normal denim jeans fabric without any problem, and the pocket lining of trousers are usually quite thin, so accidental interaction with the screen seems almost unavoidable if the screen is unlocked in the pocket.
I have actually had some problems a couple of times when the slide to unlock had been deactivated on my HD2. I once took my phone out of my pocket and it was at the confirmation screen for factory reset, and I have actually had the phone hard reset on me once which I suspect may have been caused by the slide to unlock being deactivated. I would never knowingly put an unlocked phone in my pocket, and I wouldn't recommend it to anyone, but you're welcome to do as you please.

oh, i didn't know it was that sensitive, then, i can really see a need for an apps like this.
but, what about just a normal case? slip it in and out? i mean, i think that COULD solve your problem in a 'no thrills' sorta way... but it wouldnt be as exciting now would it?

Magnet attached at the back cover

Hi all! Im in love with this community from day 1
its my 1st thread though seeking for help/advice/your superior knowledge
Thing is that i want to mount my phone in my car using a small magnet attached somewhere at the dashboard and stick my HD2s back cover which is metallic...
my question is: is it possible because of the nature of the magnet to cause problems in the phones operation?? like radio interference or something like this?
looking forward to your answers

i think a magnet may interfere with the touch screen. not positive on this but am sure i`v read somewhere about tiny magnets being in the tip of some capacitive screen stylus`s. a stronger magnet to hold a hd2 would surely result in some type of touch screen interference. but like i said am not a 100% certain.

magnetism will not affect a capacitive touch screen. It will however mess about with the compass!

A capacitive Touchscreen works like a capacitor, whichs field is "spread" over the surface of the screen. By tapping you will change the the resistance of the oscilating resonant circuit, which has a specific resistance (which is related to the dielectric medium, which is changed by your finger)
With this, the phone is able to locate your finger in X + Y axis to find out where you have tapped.

Yes, obviously it will but thats the least of my worries as it wont be permanently attached to the magnet and the times it will, i wont be needing the compass app.
so if thats the only problem i think im gonna give a try to this project...

Does this mean that a magnet at the back could interfere with the circuit of the screen? and if yes i guess is temporary right?

after some trial and error i found out that the back cover of HD2 although it looks metallic apparently its not coz it can't be attached to a magnet...

That would only mean that it is not made of an iron compound

Is that true? I know old compasses relied on a magnetised needle to work, but I thought the compass in the HD2 got it's direction from the GPS and the accelerator software??? How would a magnet affect these?

no it's a dedicated compass hardware
Actually, even my notebook apparently hurts it! Looses calibration

yes several times when i opened the compass application arround various interferences it asked me to move it in the usual 8-like movement to calibrate itself..

what about the rest of the phone and memory and SD card wouldnt it affect the storage ? i clecned out my speakerphone with a very small magnet yesterday to get all the lil pieces stuck on it.
and after that my phone(touch pro2) completely froze up and kept freezing up after first input untill i did a hard reset.

i did another little test with a small round magnet around 2cm diameter. i moved it around the back of the phone while looking at the screen and i didnt notice any interference to the screen, at least to my eyes it looked like the magnet did not interfere with the phone at all.
However i moved the magnet to the screen and tried to touch the screen gently with the edge of the magnet and the screen responded immediately and it looked very precise too! i did several presses to the screen with the magnet and in all of them the screen responded exactly as it should, just like it should with the press of a finger, i even wrote some letters as text and it worked great. so i guess thats how they make capacitive stylus..
next time im gonna try to draw on notes application and see how precise it is on that.. (as long as i find a smaller magnet that i can handle better than this one)
i might try to make my own capacitive stylus....
why not....

I have attatched a magnet to the back of my HD2 so i can use my vent mount, i havent noticed any adverse effects.
