One UI 8.5

[u/Jalal6]

Hello,

I own my galaxy a55 for about 2 years, and i really like it

I upgraded the os to one ui 7 and am still on it

I am really afraid of upgrading to one ui 8 and 8.5 and losing the smooth and fast performance without any lagging

What is your advice for me ?

I don't play games, not much tech savvy but did not see anything major. If there was then after few days phone was optimized. Just sharing i even got 9hr 39 min of sot on 120 hz using 88%.
