Help with phone that has bung calibration

[ravenflower]

I was trying to adjust the calibration on my phone and now its wayyy out of sink to the point its hard to even unlock the phone. I cannot get into my settings to do a restore because when I press the setting button on my screen it activates a completely different button, is there another way of resetting the phone? it seems to be an unbranded phone but the model number says a3qr if that helps at all.
