BBM lags like crazy on my Z30,. When I just open BBM it's find, but give it a few minutes then it starts to lag....
At that point I have to shut it down and open it again.. so I constantly have to be doing that..
really? do you have a lot of open convos? sometimes its good to reset your bbm by closing all the open conversations....and rebooting your device. How much memory do you have free?
