ULEPHONE Firmware
Ulephone Power 3/S3
A word of advice - dont rush into buying a Chinese phone based on their battery capacity e.g Ulephone Power 5 - 13000mAh battery capacity. Wait for a tear down review from techno savvy users. Because there are models that listed their humungous battery capacity but when actual measurement was done it shows it is hardly even 55% of the listed capacity. Most budget priced phones with "dual main camera" usually the 2nd twin lens is only a sensor and make sure the camera when specified as auto focus is actually mechanical focus and not software focus.
