Very disappointing product. Review on Oppo F7 Sunrise Red

Hello there I am going to share my personal experience with oppo f7 sunrise red mobile phone. I bought this phone about 1 month ago. It was running quite good for 20 days but for last 10 days it has completely ruined me. Tjis phone has 4 GB Of RAM with 64 GB internal storage memory but this phone still hangs if I use it for 1 hour continue. This phone has 16 mp rear and 25 MP front camera. This phone has octacore processor and 3400 mAh battery which runs for hardly 1 day. It has ips lcd touchscreen with corning Gorilla glass and screen size of 6.23 inches and hd 1080p screen quality. Overall features of the phone are very good and also phone is very slim but it's performance is not good as compared to the given features in price range of 16k. So thia phone is not value for money you can choose for other brands like redmi
