EOS R3 Freeze-up Issue - The likely cause!

[sbunting]

My friends,

I believe I found the issue causing freeze-ups in the Canon R3!!!

Recall the following:

1) I experienced freeze-ups with my Canon R3 the first week I received it.

2) Canon CPS took the camera in for repair, replicated the issue, reinstalled the firmware, reset it to factory settings, tested it, found no more freeze-ups, declared it fixed and returned it to me.

3) I restored my settings manually and the freeze-ups still occurred.

4) Canon replaced my original R3 with a brand new R3

5) I updated my firmware to V1.1.1 and restored my settings from a CSD file this time, and the freeze-ups still occurred.

6) In all cases my freeze-ups were such that the buttons and dials would not respond (including power switch), yet touch functions still functioned including the smart controller. It would also freeze-up, at times, while asleep and could not be awakened. Of course, since the screen was black (asleep), no touch function could work. The only way to restore the camera was to pull the battery and then reboot the camera.

I have since, of course, contacted Canon and am awaiting a response, as Canon's engineering department seems to be in a denial mode, despite a Canon repair technician in Virginia having replicated the freeze-up issue when it first went in for repair.

I advised Canon that while I await their response, I was going to, one by one, change my settings to default and see if any particular setting eliminated the freeze-ups.

My first setting change was to restore the aperture and speed change dial settings to default, as I had them reversed. No change. I still had freeze-ups, so I restored my setting.

Next, I reasoned that, since the freeze-up even occurred while the camera was asleep, the only function I had changed that would involve activity during the sleep mode would be the GPS setting, which I had set to Mode 2. I disabled the GPS altogether. Since I have done so, I have left the camera on 24x7. Not once has it failed to awaken from sleep mode nor has it frozen at all while awake and being used. I have been testing for a solid week now (on 24x7) and I'm optimistic that this is the cause of the freeze-ups, as before I could rarely go a day without a freeze-up.  

I'm asking that some of you who are experiencing freeze-ups with the R3 such as I have been experiencing to check this setting and 1) verify it is enabled on your camera and 2) verify that by disabling it that the freeze-ups no longer occur.

Similarly, those of you who have an R3 and have experienced no freeze-ups, can you verify that your GPS is disabled.

Again, I'm optimistic that this is the issue, but I'd like to get feedback from others to verify what I'm experiencing before I approach Canon.

Oh and I am in airpolane mode with GPS off etc.

When it was freezing last week, I noticed it was wigging out showing manual focus and stuttering to focus. Like another poster above, i wonder if the freezing bug happens related to subject eye detection in AF.
