Okay, here is some updates....
First of All, the VIOFO app (in my case for iPhone 11 PRO MAX) need updating. The options, settings, don't match with the VIOFO screen settings. In fact some of it won't even change it. Also, there are features listed in the VIOFO screen that doesn't exist in the app.
In my case, reset to factory after updating. Use VIOFO screen to make your changes. I use H265 before, no issue, so did the same with this update by default is H264.
This might explain some of the weird things going on. Now that I done it, I will test to see if there is other concerns. In meantime, get a copy of your original firmware before updating, just in case.
It a failure on VIOFO to update firmware, but not update their app first. Bad, bad, bad viofo. You guys need to wake up, think out of the box, think ahead. My first disappointment with VIOFO. At least tell the user not to use the app....
Concern that I need to test.
Downloading a movie to your phone, was very slow (I assuming it didn't use WIFI G5 at this time). Too slow, not worth the effort, totally useless during emergency.
Recording and viewing on your device (like iPhone), the stream was jerky, jumping frames. (I assuming it didn't use wifi g5). Totally lousy, in comparison to V1.3, it was perfect).
It reminds me of NextBase, that I dump because of that. Hopefully, I don't have to go to setting each time to change to wifi g5, it seems to reset to factory default. Need to test that later.
Didn't play with format, other then was was defaulted by VIOFO format options. Unless you want to use larger SD cards, don't see the need, nor any indication it causing an issue for me.
They added park mode timer, by default 30 mins, which is useless for me. I set to 24 hours. There is an entry timer park mode option, by default off, which is okay with me, I like to hear the beeps when I exit or enter the truck. Tell me it working, especially in the morning, after parking all night.
