Top budget smartphone under $400 (2018)

Honer 7x

 Honer is Huawei’s budget-friendly sub-brand and the 7X is the sequel to last year's 6X. Like its predecessor, it is a fiercely competitive mid-range offering, that offers an aluminum build, dual cameras and an 18:9, 5.93-inch screen with minimal bezels to match. Throw in Honor’s typically lightning-fast fingerprint scanner with gestures, and you have a lean, mean $199 mid-range machine. Available in versions with 3GB and 4GB of RAM, the Honor 7X was recently updated with Android 8.0 Oreo with many new features. For under $200, this one is a steal.

                                          Moto z2 play

   If you want to have a phone with a long-lasting battery, the Moto Z2 Play is probably one of the best choices out there. It's not quite the battery champ as the original, but it's not too far off. It's also now slimmer and more elegant, The Z2 Play runs on Android 7.1 Nougat (upgradable to Oreo) and features a clutter-free Moto skin that operates quickly. It has a very good 12MP main camera that is also able to capture video at up to 4K resolution. The Moto Z2 Play also supports Moto Mods, the magnetic super-attachments that can add even more battery, improved sound, or even a projector, but even without them, the Z2 Play is quite a good deal.

                                        Iphone SE

  The iPhone SE has once again dropped in price in September 2017, and with a starting price of just $350 for the 32GB version, it definitely deserves a place in this list. It works like a charm on all major U.S. carriers with proper 4G LTE support, and it has the Apple A9 chip, which still holds up even in 2018. It's also the only 4" phone on this list, a truly compact offering that is perfect for single-handed use. The iPhone SE has been updated to iOS 11, and will be getting iOS 12 when it launches this fall. If you're looking for a sub-$400 phone, the 32GB SE is a great choice, though if you want the 128GB version, it'll cost you $449.

                                      Lg q6

Call it the mini G6: the mid-range LG Q6 looks and feels a lot like the company’s flagship phone. It has a similar bezel-less, immersive display and it’s got a nearly identical interface.you know some compromises must have been made. Rather than having high-performance silicon under the hood, the Q6 is powered by the entry-level Snapdragon 435 system chip and it lacks the fancy dual camera system of the G6. It’s not water-protected either, and the glass back has been substituted for plastic. The Q6 also doesn't have a fingerprint scanner and relies entirely on face recognition instead, which is not exceptionally quick, but it's not that bad for the price.

                                      Sony xperia XA2
