My R3 froze up back in April. The screen is on but it will not release the shutter, allow me to change any settings or focus. The off switch does not work and the only way to power it off is to take the battery out. I never got a response back in April and it hasn't acted up again until yesterday. The same thing happened. Nothing works but the screen is on and turning the switch to off does not turn anything off. I am using the correct memory cards and a canon battery. The first time it happened I was using no wireless connections. It is now setup to use with the canon app on my phone although is was not turned on when this happened. This set up is not new - been using it this way for months with no issues. Has anyone had similar issues? What was the fix? I am traveling until November and don't have the box with me to send it in so hoping there is a solution.
