Default bug identification- might be linked to overheat?

Go to About Device - Device facts

and you should see that your available ram is only 1.xx MB (2.71GB) the important thing here is the MB. I was puzzed so i downloaded a seperate ram app, and indeed, the available ram should be 1.xx GB. could it be that this bug causes the phone to think that there is insufficiant ram, hence it keeps clearing ram, resulting in overheating?
