I volunteer at a youth club, and it’s unbelievably sad how the kids (11-18) use phones as a status symbol.
Personally, I’d opt for a secondhand iPhone 5 with large storage & a good case. 7/10 kids have smashed screens. Benefit of the iPhone is that it’s tried and tested and that they can all download the same apps. Good secondhand quality falls into budget of the phones listed above.
I’d avoid the none mainstream and stick with the ‘cool’ brands, just to prevent any social friction. Kids that age have enough to think about, without having to justify why their XYZ is better, or the same as, and iPhone. iPhone means they fit in straight away. For the minimal additional cost, I’d say it’s well worth it.
It’s very very sad, and we’re well aware of this, but it appears to be ingrained in our society now.
