Which is the best Android dual SIM 4G smartphone under Rs 8000?

After a bit of research, I came across two mobiles of different companies from which you can choose.

1-) Redmi y1 3Gb 32Gb (don't go for Redmi y1 lite, this phone is far better than that one.) 
 Price - 9000
 One of the best phone in this range, even though it has old tradition size with big bezels but rest all its feature make it a best deal to buy. Average rear camera, but 16mp front camera is a deal breaker in this range . Smaller battery ( 3080mah) as compare to other smartphone in this price range. Snapdragon 425 octa-core processor is great same as other phone(Smartron) in this range. All major sensors including gyroscope, infrared and magnetic compass.

2-) Smartron t.phone P 3gb ram with 32gb storage
 Price- 8000

An Indian company Smartron launched this phone in January 2018. It's main highlight is its 5000mah battery. 5 mp front camera and 13 mp front camera is avg. Gyroscope and fingerprint sensor present but no magnetic sensor or compass. It supports otg which I don't know is present on Redmi y1 lite or not. It's fingerprint sensor also allows people to take call by just one tap. Small screen (5.2 inches) as compare to Redmi y1(5.5 inches.) Company says its battery supports fast charging that enables a full day charge in 90 minutes of time.

There is one more phone i.e infocus vision 3 i.e available at price of 7000.
 Its main highlight is its bezelless display, Dual back camera and 4000 mah battery. This phone doesn't have gyroscope and also it has MediaTekprocessor which is not that great.
 So if looks is not your preference than don't buy this phone.

I have gone through all the smartphones available at this price range(tried my best to give you best options) and I guess these are the best smartphones you can consider.

Thanks
