ArunMKumar , via OnePlus 6 , Oct 22, 2019 : This post is a repeat of https://forums.oneplus.com/threads/landscape-mode-lock.769293/ But since comments have been disabled on the original thread without any reason or conclusion to the issue. I wanted to see if anyone has the answer to the query. Can we lock the one plus in landscape mode? If not, is there any particular reasoning behind it? Can any third party app do it? I am casting the screen of one plus on a tv/monitor to read pdfs and other documents, and i. Unable to lock it in landscape for certain apps like file explorer, it keeps switching between portrait and landscape. I please request an answer or explanation before comments are disabled on this thread.
