Children are very good at adapting to new things. I think the most important thing is to keep the lines of communication open - maybe you already have a ritual together where you decompress together and reflect the day, maybe expand that or introduce it, so she has a set “room” for her thoughts. More than “doing something”, I would encourage you to listen and see what she needs (not that I think you’re not already doing that, but sometimes it can feel like we have to ACT, when being attentive and react can be more helpful).
I personally would try to get involved in the school, as far as this is possible, get to know the other parents, get a feeling for how the community works, where/how we can socialise and hopefully get some ideas how to help her connect to the other children quickly and easy (events, clubs etc). Maybe the teachers already have some ideas on how to help integration - when a child from another country joined the school of my daughter, they did like a week or so of days where the children would show and tell something about their country or culture or family, all of them, not just the new one, so they immediatly found things they had in commonm and others to be curious about.
Be open, be curious - she’ll pick up on your attitude towards the new situation, so make it a fun adventure more than a challenge. :)
I had a fairphone 2 years back. Had the battery replaced once, otherwise it worked fine. It was a bit clunky, a bit slow, the camera wasn’t that great, it felt a bit out of date overall, but I’m not crazy about this sort of thing, I just need a basic smartphone. For me the environmental and fair trade aspect was the selling point, not the technical stats, so I can’t really speak on that. It was … a phone, lol. It worked fine. Friend of mine is using a newer one (not sure which one) and says they’ve done a good job to bring it up-to-date and especially make the battery last longer. I don’t think they aim for super high perfomance cutting edge phones, so don’t expect that. Oh, because you can take them apart, they are obviously not waterproof. Just something to know.
