The S3x and S4 are both fantastic mid-range devices of the infinix S series made with sleek and elegant glossy glass- like metal and are also successors of the infinix s3. The Infinix S4 however, is the latest device from infinix mobility, and the first infinix smartphone to come with the latest Android Pie software and a water drop notch feature. While the S3x is the first to adopt the notch trend feature. Both phones have few similarities in term of features, but their performance vary as they come with different operating system, camera features and what not.                                          Infinix Hot S3X                                     Infinix Hot S4 Screen size                     6.2-inch                                                        6.26-inch Resolution                     500 X 720 pixels                                       1520 X 720 pixels Processor                       Qualcomm Snapdragon                          Mediatek Helio CPU                                   1.4GHz Octa Core                                     2.0 GHz Octa Core RAM                                 3GB/4GB                                                    3GB Internal Storage         32GB                                                            32GB SD Card                           Up to 128GB                                               Up to 128GB Software                         8.1 Oreo                                                       9.0 Pie Primary Camera         Dual 13MP + 2MP                                     Triple 13MP + 8MP + 2MP Front Camera               16MP                                                            32MP Fingerprint sensor     Yes (rear)                                                   Yes (rear) Battery                             4000mAh                           …
