Align Screen Shortcut

If you tap and hold the middle direction button as well as the calendar button it brings up the align screen program.
Does anyone know how to disable it. Is really doing my nut as when i take the phone out of my pocket a lot of the time its on that screen. I'm actually running mortsaver but it makes no difference.
I just spent 30 mins trying to work out how and why it was bringing up the align screen when in my pocket.
Cheers
Never saw that before ... but your right. Maybe u should turn on the buttonlock in settings, lock all buttons except the power button.
Works for me..

Touchscreen Not Functioning Correctly

The screen on the my streak has been slowly degrading, to the point where i can barely do basic functions of the phone. It doesnt register touches or swipes a large percentage of the time. If I long press on the background to bring up the add shortcut widget popup, it usually will bring the phone back to 85% function. But if I lock the screen and try again, I have to go back to longpressing until I can click apps.
Often presses will register along the top bar and bring up the notification screen or short menu when I am clicking anywhere but on the top. It has happened several times while typing this.
Has anyone had Touchscreen problems with their Streaks?

Do you have a screen protector on and maybe some debris between it on the screen?
I'd recommend aligning the screen.
User Manual said:
If necessary, you can calibrate your touch screen as follows:
1 Press and hold the power button and then touch the Power off option on the screen to turn off the device.
2 Simultaneously press and hold the volume up button and volume down button .
3 Without releasing the volume buttons, press and hold the power button , until the device turns on the configuration screen.
4 Press the volume buttons to move the highlight bar on the screen to the Screen calibration option.
5 Touch the Camera button to start the touch screen calibration. 6 Wait for the device to reboot.
Click to expand...
Click to collapse
Also you could enable the debuging mode by typing in *#*307#*#* in your dialer, then in your app list you should see some new apps.
Open up Dev tools the select Pointer Location
Also another one is EmList and then select "Touch_Panel" theres a handful of diagnostic tools there that are pretty fun to mess with to see if something is physically wrong with your screen
Oh and to hide/disable debugging mode, just type in *#*308#*#*
I do also have some screen issues i had 8105 went back to 8023 and was working fine until today that it was acting up, but is better than 8105 which only let me touch half the screen, now it lets me do about 80% of the screen from bottom to top. I do have a screen protector, when I was running 1.6 didn't see this issue. Also i noticed that sometimes when my fingers are a bit sweaty the touch input doesn't work that well.
No screen protector, stock 1.6. Will try debug, thanks.
It happens with sweaty hands with dry hands its just messed up.

I just used the 6 step block method and it seems to have solved my issue. Help very much appreciated!

How long did it take to reboot after you hit the camera button?
I had to do mine yesterday as the lower part of the screen wasn't registering touches properly, as if it was about 50 pixels out.
First time round it didn't boot up with the volume keys held so i popped the battery off and started again (seems to be a common issue with this device). Then it was pretty much as standard for the boot. Keep the buttons held til the menu pops up, choose calibration, leave it until it says it's done and then reboot.
Again, should reboot as normal but if it doesn't try popping the battery off. The rear cover seems to cause a fair few issues with this!!
oh and running the calibration fixed the issue for me!

[Q] need help with my touch screen. tmous hd2

So recently i start flashing and using langthang's MIUI roms and keeping update and flashing all his new release rom. so couple day ago all of the sudden, i don' know what causes it and how it started it. my red button on far right. pressing it turn on and off the screen.so now when i press it to make the screen go back on from off mode. after i pressed the button the screen light turn on and the lock screen is there but when i touch the screen and try to move the ring(pyramid lockscreen) up to unlock, but the ring is not moving, it like there is no touch screen ability to my phone's screen.
but when i use the green button far left, the button usually to use phone. that button doesnt turn off the screen but it just turn on the screen, this button is working normally. i can move the ring up to enter the main screen.
the screen isnt cracked or any thing, but i do have a protection layer over it which been there since i got the phone and never got this problem before.
what do you guys think my problem is and how can i solve it?

Lock Screen bug

It's happening every now and then, but sometimes when I press the lock screen button to unlock the screen, the lock screen comes up but I can't unlock it, it just ignores my finger like if the digitalizer was off. I have to press the button twice (to turn it off and on again) to make it work.
Any ideas?

hello everyone... need help with screen...

So sometimes if ai press my fingers on the upper part of the screen the screen appears to stop working (at least parts of it) and I get all sorts of graphical glitches. The only temporsry solving is to press the fingers again or attenpt to kind of press the upper and buttom parts of the screen to kind of "bend it" on its back. The issue is happening everywhere, including recivery screen, bootloader and splash logo... Will I have to replace the screen?
