So this was my experience with the phone for couple of days and I'll explain why you should probably go for this phone.

Pros:
*64gb ROM(it gives around 54gb of free space)

*4gb RAM (Amazing Speed)

*Snapdragon Octacore Processor (any game with no lag at all)

*16MP Back and 8MP front with flash on both sides(Camera quality of both are Amazing,trust me don't read those comments saying camera isn't good. If they don't know how to do some fine settings it's their problem)

*Removable Back...

After use a detailed review:-

PROS = 1 ) Superb speed with no lag while gaming
2 )Front camera is good with perfect flash
3 ) Rear camera could be better
4 ) Worth all penny
6)Fast charging is awesome

CONS = 1) Slight heating while charging
2)Charging socket is delicate(my damaged)
3)ARBO (AI) is useless
Overall i would give 7/10 stars...
Must buy
Better than redmi note 4!

Excellent value for money. Hope v get Android N update . An appeal to all buyers kindly mail Panasonic customer care to give Android N update along with Arbo update. Excellent fast delivery by Flipkart.

Very nice phone, battery back up is ok.. It's Japanese mob. Bt made in India... So.. Go for it... Jai Hind...

The phone doesn't look that impressive compared to the latest smart phones. It's three days that I have been using my phone but my Arbo has not picked up anything. Hope that it works soon! Now coming to the camera, the picture resolution is not as per the mark. The pictures taken by zooming the camera is of poor quality. The good thing is the front flash. Low light and indoor photography is poor. So, don't judge the phone by its camera configuration. Redmi note 4 does a better job with its 13...

One of the best smartphones @ this price.
Pros...Display 4/5
Memory 5/5
Storage 5/5
Japanese brand
Manufactured in India
No bloatware....
Stock android experience
Fast charge
Back Camera...3.5/5
Front Camera 4/5
Arbo Ai

Only android marshmallow
Camera could have been better
for lowlight conditions

phone is good but sometimes go to airplane mode automatically. also ARBO can't understandable by me.
overall good product and value of money. moreover gorilla glass is good so I can use it roughly without tension as previously many phone owned by me got screen break.

the tap to activate the phone is most useful unlike ... all features almost same as redmi note 4. Very good for a simple phone , with lots of memory , ram , good operating system.

The quick charger charges the phone fast , but if we use this charger then the phone lasts only for a day.

Good phone, using it since few months now.
Nice camera quality, and overall feel. Fast charge works well

Few possible drawbacks (not everyone would call them)
Heats up while fast charging, but not a problem for me.
Need to lock phone while talking, to avoid pressing of keys accidently, light sensor is very sensitive even a small lift from your ear the screen comes on.
My wife finds this phone a bit slippery, but as a user you will get used to it.

Really good....
But heating problem.camera quality really awesome. Works good and fast.sound quality is little low. Fingerprint is good.best at this price.front flash is useful.really stylish.phone size fits the pocket and god to work in one hand.....
