So it's quite a bit bigger than the original SE, though the biggest issue I had with the design (on a 6S anyway) was that the metal back and rounded edge made it much slippier than the old 4/5/SE design, much harder to hold securely.
Anyway the SE/2016 was 123.8mm x 58.6mm x 7.6mm and 114g with a 4" display, the 8 was 138.4mm x 67.3mm x 7.3mm and 148g with a 4.7" display.
Significantly heavier (+30%), noticeably wider (+12%) and taller (+15%) and about the same depth (-4%).
Are there any Android phones for sale that are smaller than 138.4mm x 67.3mm though? (That are 'standard' phones, not gimmicky super small ones like the unihertz).
Some of the Android phones that seem to be known for being 'compact' are the Samsung Galaxy S10e (142.2 x 69.9). Google Pixel 4 (147.1 x 68.8) (slightly smaller Google Pixel 3, 145.6 x 68.2).
I'm having trouble googling to figure out the smallest 'reasonable' android phone available, I'm not super familiar with the market.
Aha! Sony Xperia XZ2 Compact is only 135mm x 65mm. Found one! Few mm smaller.
But I think the new SE may still be one of the smallest phones out there, even if it's bigger than the old SE. The market seems to have moved... larger.
There are certainly people (including me) who would prefer it be the old SE size... but it's not like there's really anywhere else for us to go. Except experimenting with the specialized 'oddballs' like unihertz.
With the new SE, Apple has still put out one of the smallest phones on the market, so is still serving the smaller end of the market. Which, yeah, that is weird.
When I would get into the car, it would eject out of my pocket, as I closed the door.
So, it can definitely handle being smashed in a car door, but it did bend it, and it still worked.
Still have and use an SE w 128MB size for personal use.
