83% Alcatel A50 review: A budget-friendly device with modular add-ons
Source: Techaeris EN→zh-CN Archive.org version
The Alcatel A50 is a decent starter phone with a solid build quality and adequate performance that won’t break the bank. I wouldn’t recommend it for power users, but it’s a decent phone nonetheless, especially as a first phone for teens with its modular add-ons.

75% Alcatel A50 Review: An inoffensive design that speaks to budget sensibilities

That being said, with its inferior screen, lack of NFC, lack of fast-charging — in spite of it featuring a USB-C port — and its slow, sluggish performance, it’s difficult to say that the A50 compares favourably against the now almost two-year old Nexus 5X.

The Alcatel A50 is more interesting than most $100 phones. If you're sold on the modularity gimmick it might be worth it, but keep in mind that only the LightUp cover is available right now. The Motorola Moto E4 isn't quite as exciting, but it offers compatibility with more carriers and better camera performance, making it a bit more well-rounded, and our Editors' Choice. If you're willing to spend more, the $185 Moto G5 Plus is a great option with a performance boost across the board.
