The reason behind not being satisfied with Coolpad is that
1.No Android firmware updates
Lot of bugs.
Heating issue
App crashing
Lags a lot
Less number of service centers
Accessories get unusable exactly after 6 months( Earphone, charger)
Yep its a budget phone but at least it should not lag everytime with a 3 gb ram and 16 gb internal memory.
The phone also comes with a finger print scanner
and some good inbuilt apps for use.
The problem which I faced is of service centers as there are very few service centers available in my city and few of them have already been closed
