Just search software info->software update in settings.I'm on 304 (will post screenshoot if I can) I've been asked to upgrade to 305, but I was able to root the phone (and maybe it's even a bootloader check, since there is no custom recovery, if only magisk would hide the root to the updater, but it's not in the list).On 19 I have another update with final 305, and I was pretty bothered not to be able to update even if I have the stock recovery, but somehow the update app found I'm rooted.I'm pretty sure it was 305, since I'm on 304, but now it says I'm rooted and has last update...(maybe they removed the 305 due to bugs?)
the circle says "sistem is up to date", and under the firmware version: etcetcetcetc...
3.04.
Maybe I was drunk (I'm joking I don't drink alchool at all...) but for a few days and the 19th that I wrote the post the update says there were a 3.05 but after download it says "phone roted can't upgrade"...
By the way is really sad we have not a working TWRP for this phone (all the article refer to S9Plus then they post other versione, or version that bootloop...), otherwise we can make flashable .zip and do TWRP backup.
For me is a nice ultra-inexpensive phone with 4 batteries bought, 2 sims and micro SD all separated.Nice for summer (not for picture
) as backup phone and a nice hotspot, cheaper then the big branded ones.
