If you are planning to buy new phone(4b) , then I suggest you to not buy this because of several reasons as stated below.
1. Price
Nothing phone (3a)-INR 27000 for 8/256
NOTHING phone(3a)- INR 34000 12/256
NOTHING phone (4b)- INR 39000 8/256
Why would anyone buy 4b instead of 3a and 3a pro. They have got an extra zoom lens, better overall camera, better performance, great design, glass back, symmetrical bezel display, better speakers and real glyph light.
Who would buy a Rs.12000 more phone with chin display, only same performance, plastic body, not great speakers, no telephoto lens, useless glyph matrix and main thing is like the Nothing 3a lite which was a budget phone of that series, gets update almost after 2 months than all Nothing phones. So if you but 4b, you may would receive update like this in future as this type of phone doesn’t sell that much .
So my suggestion is go to Nothing (3a) and (3a) pro which are literally better in all things and also saves way much money. 12000 if you buy 3a and 5000 if you buy 3a pro. There is no any reason to buy phone 4b over these two phones.
Think and only buy
