I have been too busy to post much lately, which is a pity because I did find an important video on Youtube regarding photos of the sun:

We'll have to wait and see if anyone reports a trashed camera or damaged eyesight. I can only hope that we do not see any of this.
On the brighter side, I am posting a link to a time-lapse that I made earlier this year. I made no specific calculations about safety regarding this camcorder, because I assumed that the calculations would not be needed. The camcorder is a Git2 with a 4.35mm F/2.8 rectilinear lens. Why did I assume it was safe? Because the Git2 series camcorders are intended as POV cameras aka "GoPro" types, and have very wide coverage. Mine is nominally a "90 degree" angle (really I think I calculated it as about 72 degrees horizontal in 1080p with no stabilization). With these camcorders it is assumed that it will be largely used without someone watching out for whether the sun is in the view, and with the wide coverage, the sun is going to be there a lot. As a "straw argument" let me estimate that in some sports, the sun might be on the sensor typically around 1/3rd of the time. If the lens / sensor combination cannot handle this then they would have had a damage problem that end users would have talked about by now.
But realistically, for most "one piece" point and shoot devices, including phones, I would expect them to be safe for this kind of use. They might not get the result you want, but they should be able to survive it.
My time lapses are usually recorded at either 1/2 hour recording for 1 minute of video or 1 hour recording for 1 minute of video. This clip took over 4 hours. The camcorder is fine. I have a new, slightly better lens that I intend to use on this camcorder, but I have not had time to install it yet.
