Yesterday, March 18th dies albo signanda lapillo! I received two new tools: an electric snaple/nail gun and my very first smartphone, the latter from $work.

I suspect I will enjoy more working with the first one (paying attention to not make confusion in their usage, as this can be dangerous ;) but, as many of you already know, I always owned and used a Nokia1100 so I'm here to collect your suggestions.

What I already know is Perl Tk run on Android. It works and the useful termux app. Then I was suggested to use AndroxIDE as program editor, but I have to ask here for more suggestions.

Infact the phone is an android one, dual sim model (Samsung A40) and I wonder if I can afford to use it as only phone, so dual life. Because of this I need to know:

1. how can I manage at least two distinct Contact Lists, with the possibility to black list one of them outside working hours?
2. the lack of the user concept is a big minus: there is something that can be done in this direction?
3. which browser can I use to protect my privacy and how to use it?
4. which file manager do you suggest, being simply and powerful? I'd like to simply decide which data will go in the SD card too.
5. which backup manager? I saw in the past backup bound to ugly propietary software aimed to backup the whole phone: I dont think this is my need, but I'm open to suggestions
6. which remote access software must I use (able to do RDP and ssh connections)?
7. there is something to check and control my privacy in a unified program? The First Time Access was a dread: fingerprints, google account details, blood type.. :)
8. there is something like a network manager, able to simplify the management of data connections of two distinct sims, the wifi of my home and office and vpn too?
9. I was unable to spot the keyboard and video plugs.. ;) no, seriously: can be connected in some way to became an emergency pc?
10. Being a perl programmer and system administrator which app cant I miss?
11. If I have the will to try to program an app where can I start and with which tools?

I'm sure you will pardon my offtopicness but I have to fill in a 20 years techonlogy gap and here at perlmonks lurk the only people I can really trust about the topic
