Honestly don't get why people buy stuff that they don't stand a chance of even other people fixing.
I deliberately didn't buy certain models of cars because they are basically irreparable unless you're the manufacturer, and I don't want to pay those kinds of prices into perpetuity, thanks. I never liked Monopoly.
Why you'd buy a phone that (last time I looked) cost £70 for a screen that wasn't even a proper Apple replacement part and voided all warranties, I'm not even sure. Especially when those kinds of damages were frequent (never met anyone with an iPhone over 2 years old that's not smashed on the screen at least), and often took out touchscreen / buttons / cameras too.
Have literally dropped my phone down concrete steps, out of windows, etc. and never had a problem even without any kind of case. However, have sent one guy's iPhone off for repair for broken screens no less than 7 times, each time the repair is more dodgy because you just can't repair it properly. And that's from a company with an exclusive deal with us for repairing 100's of iPads too.
If you can't google a replacement part, slap it on yourself, then I don't see why you'd want it. You might as well drive a Peugeot or something where you have to dismantle the rear axle to change the front headlight bulb, or things equally as ridiculous.
I honestly don't get how this rates even a 4, let alone a 6, on any kind of repairability scale, and I don't get why people continue to buy those phones, whine about the repair costs, then expect me to somehow magically fix them for free when I told them not to buy them.
