zenfone 3 zoom user reported here, so far the phone is quite smooth although using snapdragon 652. I didnt play games but heavily using social media like whatsapps and wechat for work and waze everyday. All in all it is really suitable for heavy user like me because of the beast 5000mAH battery! Camera is ok ok, not very impressive but acceptable. Btw my previous phone was Samsung Note 5.
