https://us.community.samsung.com/t5/Galaxy-S23/S23-Ultra-Lag/m-p/2512829#M2600 I'm pretty sure mine was laggy the first day or two. Maybe even 3 days. But it's more running like a champ.<BR /><BR />How many days has your device run consecutively before a factory reset? How many days did it run from the initial setup day?<BR /><BR />Not all my user apps were happy after transferring from my S21U via Smart Switch. A few apps i had to wipe out reinstall to fix then hanging up my device. Could be an unhappy app causing your lag.<BR /> Wed, 22 Feb 2023 00:16:27 GMT OffDatGoGo 2023-02-22T00:16:27Z
