Im one of the millions of TECNO fans and cant pass without narrating my personal experiencing with a tecno phone. Ive not used Camon before but I will talk about Tecno Povior 4 which is the phone am using right now. I bought this smartphone 3 years ago and it has since been my only phone. So far, the experience is good, and will recommend it 1000 times. with a 5000mA battery, Povior 4 keeps you connected for a much longer time than other smartphones can do. This smartphone also came with a super-performing quadra camera at its rare end and it doesnt disappoint at all when taking pictures. For the front camera, I would say its average; not so bad for quick selfies. No overheating even when performing highly-demanding tasks.
However, as with other tecno phones, Povior 4 has issues with the charging system. When you buy this smartphone, budget to repair the charging system after 1-3 years of use. However, in general, Povior 4 is a good smartphone.
