User opinions and reviews

Had this phone as a kid. Cannot recommend it. Even if anyone gives it to you for free, give it back to them. Charging port to battery contacts deteriorate over time. Very quickly. One day, it will literally just stop charging and then its ewaste

You should add 3.5 mm + MicroSD card slot to the search options, at least for me that was crucial to choose a phone and landed on A40, back on 2019. Also adding 5G to the equation should make sense on 2025, I guess.
