When will SHINee have a comeback?

SHINee's most recent comeback was in June 2021 with their seventh studio album, "Don't Call Me". As of my limited knowledge up to June 2022, there is no official information or confirmed dates regarding SHINee's next comeback. Comebacks are typically planned and announced by SM Entertainment, their management agency.

Since my knowledge is limited, it's possible that a comeback announcement may have occurred after June 2022. For the most up-to-date information on SHINee's activities and comeback plans, I recommend checking official sources such as SM Entertainment's website, SHINee's social media accounts, or reliable entertainment news outlets.
