Does anyone know how to calibrate the screen on the T9?
Also does anyone's screen spaz out when the power adapter is connected? (Think my unit might be slightly dodgy, although it works perfect when not connected)

My screen acts up when it is connected to the adapter. Basically if it's plugged in, it becomes useless. The calibration function doesn't come up for me. According to the manual, you must keep the menu button pressed and a keyboard will show up. At which point you can calibrate. This just doesn't happen to my unit.

this is exactly how my unit acts, so must be a common defect.
I also tried holding menu, but nothing came up.

Yes, it does seem like a common defect unfortunately. To the best of my knowledge, the calibration of a screen is a software function, where Android would have an option of how it is communicating with the screen and recognizing it. Also to the best of my knowledge, android (natively) doesn't have this option. I was very surprised when I read in the manual that this could be accomplished, because that would mean that there is some embedded software (BIOS type thing) which allows for the calibration.

Just as a means of ranting on..... my screen also has a glitch possibly due to pressure from the case, where it inadvertently recognizes input when I'm not even touching it. Though it is a sporadic thing and barely a nuisance, it is still worth mentioning. I tried to loosen up the screws that hold the screen to the case a bit, and it seems to have alleviated the problem.

The best way to determine whether this issue exists is to download a paint application (Kids paint works for me) and just let the unit be. If the unit has the problem, you will notice that the screen will show paint spots even without you touching. This should indicate where the screen thinks it is being touched for input.

My unit also does this, which i only noticed when testing toddler lock today.

Capacitive Screens don't need and can't be calibrated. This is only for resistive screens and probably a leftover from another ROM Version

This is a software bug, "last tap" happens sometimes, it just calls the spot of your last tap,but you're right,it's a nuisance

I wish I read about this before. Received my 3g version today and plugged it in to charge and got the shock of my life when trying to use it plugged in. I even posted on the Merimobiles website and support about it, I was that sure it was a bad one. I'm still not 100 percent sure though, as it's still charging and I will have to wait till tomorrow to see if it is ok without the plug. Although I am seriously doubting if this is the tablet for me now, if this doesn't work when plugged in. I / my wife / my son was planning to use it on route to keep them / me happy when up and down the motorway when back in the UK, but if I can't plug it in whilst driving (I have a cigarette lighter to plug adapter in the car)and can't use it whilst on the sofa / in bed while plugged in, is it really that reliable?

Any thoughts, anyone?

George, you are right about the pressure thing causing weird "touch" issues. It is caused by the 2nd speaker wire routed behind the screen, which there is no room for. I rerouted it by cutting the original splice, routing it along the top, and splicing closer to the 1st speaker wire. I had to cut some channels in the plastic though (very easy). Touchscreen is almost perfect now. The cover slides on/off easier too.
