I recently updated my A51 to One UI 3.1 and it has been very laggy, slow and super annoying ever since. Just 2 weeks prior to the One UI 3.1 update, I received the One UI 3.0 update and I was absolutely loving the performance. My phone worked absolutely best at One UI 3.0 but in One UI 3.1, it's just unbearably slow. Is there a solution to my problem?? Is it possible to go back to One UI 3.0 ??
