Cosmo have been my daily driver for a week now. Here are my first impressions.
Hardware:
I'm constantly trying to type two-handed with thumb typing a'la Motorola Droid4. That's not going to work on Cosmo as the amount of buttons you're able to reach without changing the phone's position is not enough for efficient usage. But even though my fingers and hands are not that small I'm still able to type this with 10 fingers in a laptop type typing. Just not as convinient as thumb typing when on-the-go.
Two of the buttons stuck in midway. They seemed to work just fine when typing but when the "lid" was closed and all buttons were pressed to roughly middle of their travel two buttons (l and f) were stuck in the midway. I popped them out and carefully checked their double u shaped parts under magnifying glass and found out some anomalies. I was able to scrape them to almost identical shape as rest of the working buttons with an x-acto knife and now all buttons feel and look identical.
Screen is ok and speaker quality seems better than what I'm used with phones so far. Hinges do squeak but I dont mind that. I'm not yet confident with my knowledge of what accessories to plug in to which port. That may be something I'll take a look in the future.
Software (not codi. that's last section):
Most of the software that had Planet in the beginning of the name were completely useless for me. I don't want to become dependent of software that may not be available or could not work on another hardware, so I ended up disabling them apart from sync addon (Not clear if that may broke something) and Codi updater.
Some of the functonality of the buttons have changed. First the silver button acted like an power button, but now it's acting as a back button in Chrome Browser (also alt+esc seems to act as a back button... weird)
On some apps alt+tab lights up caps lock light on first attempt and initalizes task switch on second attempt. Telegram is one of those apps.
I ended up changing the keylayout with FinnQWERTY -app (swapping ä and ö) as the default layout was weird and anything but optimal for Finnish language, that app may have something to do with the weird behaviour of buttons?
Typing english (this text for example. written with Cosmo) relies lot of ':s and that's (again) not intuitive in finnish layout keyboard. Maybe with more training I'll be able to type better without looking at button prints.
Codi:
Had to be disabled as phone kept crashing/rebooting 5-10 times a day. Sometimes 3 times in a row within 10 minutes. Now codi disabled perfect uptime or 3 days and battery life seems to be almost doubled compared to the time with codi on.
Also phone kept locking itself in middle of typing etc. when codi was active. Now that codi is disabled - no more random lockscreen interruptions.
Summary:
This is the only phone with native finnish keylayout, so what are my options?
I like it but I don't yet know how to use it efficiently. Without codi it' definitely not a phone as I can't even check the clock one handed. Not to think of doing anything else one handed. no more quick bus timetable check or anything unless you're prepared to stop and use both hands.
I hope codi would be fixed in an upcoming firmware release. And I hope Planet Computers would open their bugtracker to the public.
