My sales outlet currently have both device in stock and personally I've used both device but I found Infinix Hot S a capable companion than Camon C9. Not worried at all by the 1sim + SD card tray or 2 Sims no SD card as I have other phones. It all boils down to preferences as I found Hot S battery more stable than C9 and the fingerprint scanner on the back no be here ooo as one could employ it to scroll gallery, take calls unlock your device without even touching your power bank. Working with my hot S camera I made a few bucks in just a few days.
If you're in my location (South East) I'll avail you with both phones to toy with before deciding on the one to buy either from me or elsewhere , Regards.

Will hit you up on WhatsApp
