I am using redmi note 4 from 5months, it is having 4gb ram but it is always slow , some apps are stopping unfortunately, and mobile charger is also not working , my last used Mobile is redmi 2 that had blasted while changing it and mother board is totally damaged and I kept at a side and bought new phone but it is also same like that, I can only suggest this mobile for using 3 months and exchange it if not you will suffer, and resently my brother bought moto g5 plus, for 15000 which is just 1000 more than my phone, but its performance is extrordinary, I can see more good qualities in that mobile, and one thing when I would call to some I one after I disconnect the call the screen doent show display for 2 minutes
