Had my MG 4 luxury (got the R33 software update) for 2 months now. These are the software issues I've had so far.
*infotainment screen stays black sometimes after cameras has been in use. Fixed on next drive or hard reset infotainment.
*Sometimes volume control can't increase volume, only decrease. Need to hard reset infotainment screen or works on next drive.
*Cameras not working if infotainment screen has been hard reset while driving - see the two above issues how I noticed this.
*Once when I started the car I got an message on screen that disappeared so fast I could only see that it said something asbout low outside temperature, on a day with 25C outside, this trip the car ate the battery twice as fast as normal. Yes I checked if intelligent battery heating had came on, and even switched it on and off again. The next trips the car also ate battery twice as fast as normal. After charging it, it went back to normal consumption.
Beside that there is the normal software flaws reported by others as well:
*LKA not great (half the time it tries to pull you closer to the line instead of towards the centre of the road!).
*ACC not great, when driving alone with no other cars in sight it slows down massively in curves. And in traffic it is not very smooth, even after changing regen to adaptive and mode to sport (this massively helps tho). Can I have normal cruise control please, that doesn't slow down in curves?
*Infotainment doesn't support folder playback of mp3 files.
*Sometimes phone looses BT connection, only happened once on R33, on R30 it happened like twice a week.
Overall great car to drive, but with poor software. The only hardware complaints I have is the poor sound system and only average seats. Handling is excellent, ride is excellent.
