I can't answer the "others" since the only tablet I have is my A500. Mrhelper has several tables and would be more aware of what, if any other tablets have the problem. It is only a problem if you have ICS installed. I don't know if the problem still exists if you update to JB or not. I do know it has caused alot of ill will tward Acer for the problem they have caused. They did the same thing to us with the 3.1 update that killed the wifi on so many tablets around the world. They aparently don't have qualified people doing their pre release testing before they send out updates. That is one reason I will never invest in another Acer product again. I love my tab let, and with this forum it has made owning an A500 far less risky.
