Soooo... after waiting for a whole week for someone to answer my question i decided to take a risk and upgraded my LG-V20 f800l to latest android pie, surprisingly and it was worth it,for me this update is the best one yet,however it is not as fast as android oreo but still performance wise i think it deserve a thumbs up it isn't laggy like previous version,and who ever is going to install this update don't forget to format your phone after upgrading and leave phone still for almost half an hour after that do as you please
