Samsung lower model always sucks with hang problem.I just bougth this phone for my secondary jio sim but it not worth a penny.
Coming to the display samsung atleast put a 720p hd display with it.Sometimes the touch also remain unresponsive.
Only thing I notice is the battary life with tizen ver its a good option.But the connectivity also poor.
Don’t go for 4G device like this. Invest on Mi phones.You get a mi 4G phone with better spec.why waisting money on samsung mini 4G phone.
