They are cost-effective android phones, if you want to own an android phone, I think they are good choices for you.
We can make a comparison between them, coolpad F1 equips with MT6952 octa-core CPU and Mail-450 GPU, which are better than quad-core and Mail-400 on honor 3C. Both 5 inch phones configurate with 2GB RAM and 8 GB ROM, but the back camera of 3C uses Sony BSI technology, which brings good performance in night shot. From the score of AnTuTu, F1 is better than 3C in several tests.
It’s hard to choose one from them. What’s your selection?
