Brand dilution and product confusion are major issues for many Android device manufacturers these days, but Asus is especially weird and careless about naming its mid to high-end smartphones.

The ZenFone 3 family includes a bunch of models with very similar numbers, almost identical looks, and closely related specifications, two of which finally follow the flagship Deluxe on the Nougat bandwagon today.

Expect over-the-air 7.0 OS promotions to arrive on the ZE520KL and ZE552KL any minute now, after the ZS550KL got the ball rolling just last week. All three handsets are of course a little late (almost very late) to the build N expansion party, having had problems with earlier versions of the software update back in January.

To clear up confusion regarding the minor differences between these Asus ZenFone 3 configurations, let us point out that the “international” ZE520KL currently costs $250 on Amazon, while the ZE552KL fetches an extra 70 bucks or so, no valid US warranty in tow.

You get either 32 or 64GB internal storage space, 3 or 4GB RAM, and a 5.2 or 5.5-inch Super IPS+ LCD screen with Full HD resolution. The smaller ZE520KL obviously packs a lighter 2600 mAh battery (compared to a 3000 mAh cell inside the ZE552KL), but both third-gen ZenFones measure 7.7 mm in thickness, Snapdragon 625 power, 16/8MP cameras, fingerprint recognition on deck and everything.
