I had my A53 5G receive its 1 June 2022 security update the other day, in the UK.
It was a fair size update at 917 MB. It did include stability to the camera and system in general. Thankfully no issues to report as battery life is still incredible. Plus the camera is still working great too 🙂
A53 5G has improved a lot since release. I got a very early one to replace an A52s 5G, and the A53 was very slow in comparison. Now the A53 runs great, there's very little difference in every day use compared to my OH's S21 FE 5G.
It's a great phone and no regrets from me in getting in. Just had a notification pop up now telling me battery low. 15% left with 2 days and 10 hours use since last charge! It's incredible. I should point out again though that I'm not on social media, such as Facebook or Twitter. I do use YouTube, Samsung Members and lots of news and sports apps.
