I got my update yesterday. Having issues with fingerprint unlock on AOD and taking calls, other than that it's fairly fine. If you bought from a carrier, it might take longer, as compared to buying direct.
I have the latest update with One UI4 and Android 12. I have no problems with my A52s 5G since updating it yesterday. My phone came from Vodafone when I bought it. The only thing I had to do was to go into my mobile settings and enable my mobile Internet which was not an issue at all.
