These are some of the latest cheap Smartphones in China based on the MediaTek MT6580, MT6735, Spreadtrum SC7731 and SC7715. Here's a $37 iPhone 6S clone with a removable back case to support removable battery, 3G dual-sim, it runs a 5" qHD display on a Spreadtrum SC7731 Quad-core ARM Cortex-A7 (I say A5 in the video by mistake, it's actually A7). 512MB RAM and 4GB Flash but expandable by MicroSD slot. One of the world's cheapest Android phones is the $25 SC7715 single-core ARM Cortex-A7 phone with 3.5" display. A little higher specced are Huawei Mate 7 and Huawei P8 clones at $44 on Spreadtrum SC7731 and for $49 you get 5.5" qHD and 5" HD phones on the MediaTek MT6580 Quad-core ARM Cortex-A7. For LTE I found a 5.5" qHD IPS on 64bit MediaTek MT6735 Quad-core ARM Cortex-A53 with 1GB RAM and 8GB Flash. Sorry I didn't prepare this video well I say many wrong things about the CPUs, prices, Android versions etc check the annotations I try to fix it there.
