Android tablet with bluetooth mouse - no on screen keyboard!

[Android Central Question]

So, a few years ago my phone/isp provider offers me a better plan which I agree to. A "sweetner" is a free tablet -Oh OK. This tablet is not all that crash hot but since it was free, well, I'm not one to say no to a freebe. I soon discover that the touch screen is quite poor and rather frustrating, so since it is bluetooth compatible I investigate bluetooth mouses, and after buying a logitec mouse things are much easier with a proper cursor and proper buttons to click. BUT, the tablet now thinks that I have a bluetooth keyboard and mouse, not just a mouse, so if I'm doing something that requires text input, the on screen keyboard DOES NOT APPEAR. Arrrrghh! Am I stuck with this or is there something I can change in settings to allow the on screen keyboard to be used at the same time as the bluetooth mouse? The android version is 4.0.4_3.42 which I think is an old version so any answer will need to take this into account. Thanks in advance to all you Android experts out there. Ray.

I am having the same issue with my Sony Xperia Z2 Tablet, but oddly not with my Sony Xperia Z5 phone. With the phone, I can use the mouse to click on the keyboard keys even. With the tablet, no matter which mouse I use (I tried several) there's just no way to use the onscreen keyboard, and that is the latest version of Android.

Now, in some forums people suggest going to "Language and Input" and manually changing it there, but in my device it lists the physical keyboard as the mouse and "Xperia Keyboard" is greyed out. There is physically no way to manually set that, at least not in my device.

Google is REALLY bad when it comes to intentionally preventing users from doing something, which occasionally leads to problems like this.
