Rollr gunk - P3300, MDA Compact III General

As I suspected, even though I look after my phone, some gunk has got inside the roller ball somewhere.
Is it possible to clean the thing?

Hall sensors are responsible for cursor displacements. So dust or other kinda garbadge can hardly affect RollR's ability to move the cursor.
It was told me at the service centre, where the sensors of my gudget were being replaced: my RollR suddenly stopped moving the cursor to the left .

Everything is moving on screen just fine, but the ball keeps getting stuck!

Phone display keeps coming on during calls

Has anyone noticed their phone likes to turn itself on during phone calls as the phone touches your head?
I thought that could be fixed with Advanced Configuration Tool and these options:
◦Phone sleep during call
◦Fast sleep during call
But they both are gone. They were there on my Kaiser. Any ideas?
It's supposed to turn off due to the proximity sensor. I'm using a T-Mobile USA TP2 and it turns off as it touches my ear. One way you can test this, if you haven't already, is to call a phone, then as it is in progress, lay the phone with the screen up, and put your finger across the top of the facade of the phone (cover the top area where the earpiece is). When I do that, in order to replicate my ear towards the phone, the proximity sensor blanks the screen.
As for the AC tool settings you mentioned, I've never touched those, so mine are on the default settings.
Hey, wow! You're right! When the device is against my ear, the display is out. As soon as I pull it away, even slightly, it turns it on!
I'm simple, I know. My wife tells me that all the time.

It's okay, when I first got my TP2, I encountered the same thing you thought was a problem. Then I saw a video online demonstrating proximity sensors and the guy on the video put his finger along the top/speaker area of the device and the screen turned off. I replicated his actions on my TP2 and realized that the proximity sensor activates when something is touching it or gets fairly close to it. BTW, we're all simple; we just excel in different ways!
LOL, me and the wife learning this stuff too. Hey, heres another (which i just created a post for), GO rub a magnet on the face of the phone while the screen is OFF, right over the tiny keypad. If you have a soft case with magnet in the flat, go see the funky result

Well since I'm already here and I don't want to search for that post (sorry to the Mods since this is irrelevant for this thread), I can answer that too. It's already a well-known issue. The magnet tricks the phone into thinking either the keyboard and/or the stylus is being opened/taken out. However, it is more accepted that the phone is being tricked into the keyboard being opened. There's a registry edit posted on these forums that can fix that, but the downside is if you want the screen to turn on when the keyboard opens, it will no longer turn on without having to press the screen wake-up button.
I'm just using the Slide2Unlock v.204 for WVGA devices. It keeps the phone locked even if the screen turns on. When I slide my phone into my magnet-clasped holster, it sometimes turns on. It's just a habit for me now to check the screen once it's in the holster, so I can turn the screen off if it woke up by itself.

How to keep screen on when answering the call

Using Desire for months and everything prefect except one thing. Sometimes I need to press the button on the screen after some system message which need to be heard first. When I put the screen on my ear then its off. I can use the headphone sometimes but not always. I believe its because of the sensing function but cant find the place to turn it off. Could anyone who can tell me how to keep screen on when answering the call? Thanks in advance.
The screen goes off due to the proximity sensor, but it should be back on again when you take the phone away from your ear.
This definitely works for me, though I can imagine that if you have your hand close to the proximity sensor it could cause problems.

Dave
I tried again and notice that, sometimes the screen can come back but after long time waiting, but in most case it cant. I am not sure the position where the sensor located. I am using the zagg invisible shield screen cover and not sure if that caused the error of the sensor. Anyhow, is here a place to turn this face sensing function off?
PS, after I cleaned the screen cover then it seems get better response time to show the screen after move the phone away from my face. But still not rapidly as normal phone with keyboard and influence the using experience. So if there was a option to turn this face sensing feature off then it could be better.
I found this link where some one who had the same issue found it was related to their Zagg protector, but on the same thread there are others who have had no such problems.
The proximity sensor is in the top left of the screen, within the black border. circles - see here.

Edge of touchscreen non-responsive, bad digitizer?

About 2 months ago I started getting phantom touches on my screen, always on the right side. In the app Dotty, I could create the touches by moving my finger near the right edge until a circle would appear and start barely moving up and down really fast. This would be the primary touch point and other touch points would show on the screen in Dotty but in any other program all secondary touches were ignored(keyboard, homescreen). This created the illusion of the touchscreen simply not working. To fix it I had to sleep/wake the phone a couple times until it went away. This issue would come and go and seem to be really bad for a day then there wouldn't be a problem for a week. As of now, the phantom touch point problem seems to have gone away. However, the right 1/4" of the screen no longer registers touch. This mainly only affects the P key but is quite annoying. The strip that doesn't work runs from x:287-320(edge) in Dotty. I've flashed, re-flashed several roms and can't seem to fix the problem. Any ideas? Is this a digitizer gone bad? Should I contact HTC/is it covered by the warranty?

[Q] Possible to reset the Accelerometer or Touchscreen?

I have 2 annoyances with my Xperia Play -
1) The Accelerometer is off-level. When i start an accelerometer game, the thing affected by the accelerometer normally starts to tilt forwards. I need to angle the phone to make it "level" properly. Games that can reset the accelerometer work fine obviously, since i can reset it, but games that do not have that option are unplayable as everything tilts the wrong way and is not level.
Anyway i can reset the accelerometer?
2) Sometimes when i touch the very right hand side of the screen in landscape mode, the left hand side of the screen activates. Very annoying when typing as wrong letter appear. And some games get annoying. Any way to reset the touch points of the touchscreen?
Also, does the Xperi Play have a Gyroscope? some say yes, others say no. If yes, can i perform a reset on this too?
Thanks for any answers.
Most games are made that the neutral position is under an angle and not when the device is flat. This is done because most often you hold the phone in your hands a bit before you and you look at it from above with an angle. I don;t know of a way to reset this.
Also I don;t know how to calibrate the touchscreen. You can use this app: http://forum.xda-developers.com/showthread.php?t=1045374 to check where the touchscreen is faulty.
Hi, I have a similar problem with xperia x8. When playing e.g. the 'Falldown' game from the market, the ball goes to the left in neutral position. It's quite annoying...

[Q] Screen remains static when keyboard is slid in

Hi
I bought a new RHOD100 and am running Stock WinMo 6.5. First few days the phone worked beautiful. But about a week of usage landed me in this condition.
The screen only lights up with the keyboard is out and not tilted. Other than that, if it's slid in (portrait mode) or when it is tilted up, the screen freezes to whatever it was like when the keyboard was slid out. The touch functions work, I can hear screen tap sounds, and if I click on the right icon things open and close too, but the display remains frozen until I slide out the keyboard and/or undo the tilt.
Any ideas how to fix this? Is that hardware or software?
I have never dropped it, nor exaggerated the tilting.. Can it be the Flex cable?
Definitely hardware... almost 99.99999999% sure this issue is hardware.
I'm betting it is indeed the flex cable. If you're feeling brave, you can attempt to take the phone apart and see if you can find the issue - keep in mind, this is very delicate and tedious work. Need a steady/careful hand and a lot of space! Good tools help too .
