It is July 13 and today my Ring doorbell suddenly has gone back to showing Battery and no white ring of LEDs.
This is not a firmware issue. To me, my experience and that of others confirms this is a mechanical issue.
The act of a person pressing the button on the unit flexes the connection by the pins and the springs wear out.
When I have time I am going to go ahead and remove the circuit board ribbon cables and expose the mechanism underneath the board and see if there is anything to be done.
Or I might chicken out and put two blobs of solder on the gold pads like one person did.
What is interesting to me also is that the failures came at a point of increased temperature, causing the unit to be much hotter overall.
Makes one wonder if the tiny springs lost their elasticity due to excess heat, which would explain the withdrawal of the pins from the pads.
