My Desire HD has always been completely unusable when charging. The screen doesn't respond correctly, is slow, and if i try and open my text messages or anything it will open something completely different. If i want to use it, i have to pull out the charger then continue charging when i've done what i want to do. I read in an Android magazine last week that this is a common problem and can be solved by downloading the latest software which i have done but to no avail. I always keep my phone up to date. Anyone else fixed it by doing something else? I'm using the charger it came with and have tried plugging it in to different plugs around the house.
