TECNO Spark 7 Pro Review: a glamorous entry-level smartphone 7.9 Design is great and the addition of case / earphones in the box is a plus. Price is good, the mobile took an OTA update and looks excellent in my hands. I am suggesting this handset as a good buy especially for those who are not into video recording.
