i have been getting a processor full or at max(will try and screen shot next time if possible). Not sure yet if its something i have changed in the settings. Its just started doing it, also says may reduce performance or along those lines. Its not end of the world if i can not figure whats changed(iphone 6s plus all fresh and just for dji app), i will have to use my actual phone. Just would be good if i can leave this as my dedicated screen. It does get quite warm during use, but it has done being an older phone anyway. This app seems quite demanding, maybe a little too much!
