>>Now I got that phone and I'm not using it (except once when I used it as a remote for my camera, also drains battery fast, on both the phone and camera, because they become just fancy wireless NICs). Trying to find a decent url with tools to root it and install LineageOS instead, then maybe I may start using it. Meanwhile, my wife bought a Nokia 216, yes with just a dozen buttons, but it's small, undemanding and even has both side cameras.

>If my trusty E51 were to disappear, I'd look to find a used one in good condition at, max an E52 for main phone usage. On my E51 the only thing different from factory is 3rd battery by now (and I can take out battery whenever I feel paranoid enough!) plus the plastic on-off button has crumbled away. So now the on-off bare metal button is protected from accidental pressing, as I need a key to reach it ;-))

Just in case, I have a spare E71 and daughter has an E72 somewhere, so we're supplied indefinitely. I do hate E71's bass ackward headset plug (left speaker and mic cable swapped), but then I don't really use the headset at all.
