I recently bought note 4 as I am big fan of phablets. Till date its a best phablet out there in market which is best for multitasking , taking good quality picture, well designed looks , and gorgeous super amoled display. I use this phone for purpose like playing heavy games, taking picture, day to day work.
Its quad core snapdragon processor combined with 3 gb of ram helps in running this device very smoothly without any lag or any issues. When it comes to battery backup my device is way so good in battery performance as it runs almost 12-14 hours with only single full charge. And now after updating it to marshmallow its still work so smooth without any lag. According to my opinion its still the best phablet out there in the market.
