Any negative impact you noticed like battery or performance or camera issues..? Any hardware related issue like vertical line can be green blue etc.. spen issues, connectivity issue ..!!
Nope, really none so far. I think if you have Factory Reset during Android 11 to 12 jump, you'll be fine. Just Wipe Cache from Recovery if you face any issue.
The device does feel considerably smooth to me. Home screen navigation, app opening speed and overall experience seems a bit faster. Very few people can notice this imho.
Battery life is similar...that depends on network strength stability as well.
