These connection issues and poor signal strength and quality are why I didn’t buy one , it’s obviously a fantastic little drone but it’s had these problems from the start and that’s what put me off buying it .
I do have an issue with mine when taking 48MP photos, it seems to take a while to “process” them and in that time if you move the drone it isn’t showing movement on the screen, seems to take a while to catch up.
There is always a slight lag of no response when taking 48mp images before they’re processed.
Its not SD card speed related as it does it on all of them and internal storage.
All i can guess is sometimes the CPU just gives up totally or some error on processing and it never comes back online properly.
My incident it was whatever stock firmware (no mods, no FCC, nothing) that was around in November last year. Using the RC-N1 connected to my phone.
It may have done it to me once previously in the Lake District where i had a similar incident but i may or may not have been doing a pano at the time - i cant remember.
In the case of my confirmed incident the logs just stopped - a brief “weak signal” and thats it. Drone at the time some 80m away horizontally and 40m vertically in clear line of sight and previously full bars on signal quality.
Definitely isnt a real signal problem as even when a metre away trying to land it didnt return, nor did USB cable cycling, RC power cycling etc.
Drone power cycle worked right away and the next flight happened without issue.
For me its not a huge issue as i very rarely use the 48mpixel as in most shooting conditions the image quality is far below what i find acceptable. The colour shifts and fringing in particular on bright high contrast areas arent easily fixable.
Related note:- plenty of people on DJI forum smugly proclaiming “it doesnt need precision landing, just land it manually” seem not keen on admitting the fact that if events like the above happen you’re entirely reliant on the automatic RTH landing accuracy.
A lot of flights take place for me off footpaths surrounded by trees, waters, sometimes roads etc. You don’t aways have a nice 30m+ open, obstruction free area to fly from “just in case”.
If it happened on my Mavic 2, im confident it would land within a few cm of takeoff. On the mini 3, its 3-5m depending on satellite geometry.
