Same here! Been using the 1020 for 3 months & love the camera- have even blown up prints from it to 24 x 18 inches!
Suddenly this morning I discover it won't focus automatically or manually- it searches for a focus when screen is tapped or shutter button partially epressed, but won't capture a focus- you can see it hunt for a focus & pass through a sharp focus but won't lock on. How frustrating!
The cam seems OK only close in, as close as 12cm, so I can use it for macro.... All other camera apps show the same problem.
The app is up-to date- version 4.5.1.7
I suspect it's a hardware problem, and I may be in trouble as I didn't buy the phone in Kenya where I live, so no apparently |I've warrantee here!
I doubt very much if a factory reset will do any more than cause me unessary aggro.
Help? I've stuck to Nokias as my primary phone since the mid ,90s & this is the first defective one for me.
