Upgrade: leave the past behind
So my 6 year old phone decided to go on mute, permanently.
I tried various remedies, restarts, factory resets etc, but none resolved the problem.
The only way forward was an upgrade, a new phone.
So a new phone, well second hand, was acquired and the upgrade made.
But as the software transfer was complete a sneaky ‘feature’ remained. A shadow of the past!
Now the new phone showed the mute button was still on!
For me a picture and a lesson that dysfunction from the past can unwittingly imprint the future.
