With each generational increase of display size, The number of times I drop the phone over its lifetime increases proportionally. I've used android phones from 2.8" to 5.7" display as daily drivers over the past decade.
I assume, Many with small hands(palms) do face the issue of dropping phones, So I finding it quite surprising that 'Easily Repairable' wasn't included in neither 'Must have' nor 'Nice to have'.
Repairability is so important to me that, I have stopped buying new smartphones since 2017. My last/current phone has full-metal construction, is easily repairable, has security updates(sans proprietary blobs) via LineageOS and I'm planning to switch to a postmarketOS device from near-same generation for better security(Only bootloader is proprietary).
IMO in the age of Fairphone, there's no excuse for a non easily-repairable phone; Especially one which has community interests in mind. I wish you the best on this endeavor.
Have you come across pop sockets? Small collapsible self-adhesive handles for the back of your phone. They’ve made an absolutely massive usability difference to my phone usage (although I aim for the smallest handset I can get without compromising too much on quality anyway). Total game changer
Btw checkout Swiftkey's one-hand mode for typing, If you haven't already.
Fairphone, Founded on the principles of ethical consumerism have consistently delivered on their promises which by itself is an extraordinary feat in the world of smartphones (or) consumer electronics in general.
Occasional but common criticisms on their devices from HN include specs not being competitive with flagships and build quality not up to expected levels(But newer devices have got good feedbacks on the build quality).
They are only available in EU + few other countries, If you don't live in their supported countries list then getting their phone might not be advisable as getting the parts easily for repair is their main USP(Besides telecom radio support).
So if you use phone as a utility and not as sustenance then Fairphone is a good choice if you can get it, Besides money goes to a socially-invested business.
Weight is indeed and important factor. I recently held an iPhone13 Pro Max with acrylic case and was shocked by its weight,
iPhone13 Pro Max: 240g
Pixel 6: 207g
I hope that extra weight goes towards rigidity of the phone, Anyways its not intended for people with small hands.
