I've got an iPhone 5 running iOS8. It can't use a sync cable, because it came broken when I bought it used in January 2015 (no returns accepted, and no resale value if it's broken, so I just kept it, but barely use it, would prefer to stop using it altogether, and only haven't yet because there are files still stuck on it).
I just spent like two hours trying to upload my photos to Google Drive and Onedrive, and I only just figured out how, because the apps I was using seem to be designed to give the user a hard time with uploading (Drive app doesn't seem to have an Upload option, Photos forces me to select files one by one instead of hitting Select All, Photos forces me to only upload ten files to Drive at a time, drive.google.com doesn't work on my iPhone when I try it, etc).
I've figured out how to back up photos (using the Onedrive app works well enough), but I still don't know how to back up my files from the Notes app, the videos from an app called Download,and the audio files from Smart Recorder and Voice Memos. These apps don't have a "share" option built in, and I don't have or know of any app that can access those apps' files (I tried Onedrive, and it only lets me to choose files from Photos).
Is there any way I haven't thought of to transfer these files to another device? I'd prefer not to resort to copying my Notes into emails, recording the playback of my audio files with another device and filming the screen of my iPhone as it plays my video files, because doing all those things would take forever.
