Oukitel F150 Bison 2021 delayed notifications

[max_green018]

good day mga ka PHC, ako lang ba nakakaranas ng delayed notifications ng model sa itaas? maganda kasi yung specs nya especially shockproof at waterproof, kaya lang delayed notifications lalo na sa messenger, whatsapp, etc... minsan sa group chat late ko na nababasa, kailangan buksan pa yung application bago ma-update yung messages. baka po may solutions kayo, nasubukan ko na yung unrestricted data usage at battery optimization, salamat ka PHC
