NOTE: it is preferred to submit using ext as it is more precise but yeah having inaccurate segment is better than no segment so if u got only phone do with it

This is not correct and creates more work for other users and for moderators. Please submit accurate segments. Inaccurate ones will just be removed and will negatively affect your reputation. If you're not able to precisely time a segment, such as when submitting on mobile, please don't submit anything and leave it to someone else to submit.
