I bought redmi note 4 3gb model 2 months ago. After purchase I get a bad camera. It has 13MP camera but 8MP camera quality. Not original colours. Artificial colours picture I get everytime. No Screen protector pre-applied, so I use my device carefully. And we all know that if it causes screen damage, repair cost will be nearly 5000-6000 rupess in cost. Which is too expensive. This device has an avarage selfi camera. Not so bad but not so good. MIUI is a heavy ui we all know that, it only avails 1.4-1.6GB of RAM around 3GB when there are no running apps in background. When it runs too much application at same time it only avails 420MB-660MB RAM around 3GB. Which is too disappointing. Only single app takes 350-400MB of Ram. So Ram management is too bad in this device. Let’s come to the Apps which is pre-installed on that device. Gallery app is too much laggy. When I connect OTG device a pendrive its inbuilt file explorer always lags and cause Unfortunately Stopped issue. Sound Quality is too bad in this device. Afterall I don’t recommend anyone to buy this product.
