There is a phone on sale in India right now whose second rear camera is 0.08 megapixels. Not 8. Not 0.8. Eight hundredths of a megapixel, which is roughly 320 by 240 pixels, which is less than a webcam from 1998. It exists so the box can say dual camera. This guide is about the 4 things on a spec sheet that actually predict whether a phone takes good photographs, and the one thing everybody looks at that does not.
"Is the camera good or bad" is, by some distance, the most common thing people ask us about a phone. It is also the question a spec sheet answers worst, because the sheet is written by the people selling the phone and they have had 15 years to learn which number impresses.
You cannot judge image quality from a specification, and we will not pretend otherwise - we have not shot with these phones. But you can rule a lot of phones out, and you can spot the ones that have quietly been built to photograph well rather than to advertise well. Here is how.
The number on the box is the least useful number on the sheet.
Megapixels measure how many dots the sensor records. They do not measure how much light it collects, how well the lens resolves, or what the processing does afterwards - and those three decide the photograph.
The easiest proof is to line up phones that share a number. The Motorola Edge 70 Fusion has a 50MP main camera. The vivo Y21 5G also has a 50MP main camera. One of them stabilises that sensor optically and records 4K; the other does neither and carries the 0.08MP sensor from the top of this page. Same headline. Different cameras. Not close.
Higher numbers are not automatically better, either, and they are not automatically worse. What a 108MP or 200MP sensor usually does is bin its pixels together - four or sixteen at a time - to produce a cleaner 12MP or 50MP image. That is a real technique with real benefits. It just means the big number was never the resolution you were going to get.
Treat megapixels as a category label, not a score. Then look at the 4 things below.
Triple camera usually means one camera and 2 decorations.
Here is the arithmetic nobody does at the counter. Take the rear camera line and remove every sensor below about 5MP. What is left is the number of cameras the phone actually has.
50MP + 13MP is 2 cameras. 50MP + 8MP + 2MP is 2 cameras and a macro nobody uses. 50MP + 2MP is one camera. 50MP + 0.08MP is one camera and a rounding error.
A 2MP macro or depth sensor produces images you would not keep. Its real job is to let the marketing say "triple camera" and to let the retail listing carry 3 numbers instead of one. Our position on this has not changed: two useful lenses beat three where one is a 2MP macro.
What counts as a real second lens is an ultra-wide of 8MP or more - a genuinely different focal length that lets you fit a group, a building, a room. That is a second camera. A macro is not.
The Samsung Galaxy F36 5G is the honest middle of this market: 50MP main, 8MP ultra-wide, and a 2MP macro that is there for the spec sheet. Two of those three are worth having, which at its price is a fair deal - as long as you count correctly.
Optical stabilisation is the single most predictive spec under Rs. 30,000.
Optical image stabilisation physically moves the lens or the sensor to cancel the shake in your hands. It matters because of what a camera does when the light drops: it holds the shutter open longer. A longer exposure collects more light and also collects more of your heartbeat, your breathing, the bus. OIS is what lets a phone hold that shutter open long enough to be useful.
This is why 2 phones with identical 50MP sensors can produce completely different indoor and evening photographs. It is also why OIS matters far more than megapixels for the pictures people actually take - dinner, a lit street, a function hall, a child who will not sit still.
Electronic stabilisation, EIS, is not the same thing. It crops into the frame and shifts it around to smooth out motion, which helps video and does almost nothing for a still photograph in low light. A phone that lists only EIS has no optical stabilisation.
Plenty of expensive phones still skip it. The OPPO F33 Pro 5G, launched at Rs. 37,999, has a 50MP main camera with no optical stabilisation and a 2MP monochrome sensor beside it. That is not a cheap phone, and the camera hardware is simpler than several phones costing half as much. If you take one habit from this guide, make it this one: find the letters OIS on the spec sheet before you find the megapixels.
Video ceiling is a proxy for everything you cannot see.
Look for the maximum video resolution. If a phone caps out at 1080p, that is usually not a software choice - it is the image signal processor in the chipset telling you how much camera pipeline the phone was built with. The same silicon that cannot push 4K is generally also doing less work on your stills.
It is a proxy rather than a rule, and it fails in both directions. Some phones record 4K with no OIS at all, which gives you sharp, shaky footage. Some perfectly good budget phones stop at 1080p and take fine photographs. But as a thirty-second read of a spec sheet, "does it do 4K" separates the phones built around a camera from the phones built around a price.
Check the front camera's ceiling separately. It is frequently lower than the rear, and if you shoot a lot of selfie video that is the number that matters to you.
Fixed focus is the spec hiding behind the megapixels.
Front cameras have had an arms race of their own - 32MP and 50MP selfie sensors are now common well below Rs. 25,000. The number that is not advertised is whether the lens focuses.
Most budget selfie cameras are fixed focus: the lens is set at one distance and everything nearer or further is soft. At arm's length that is fine. For a group shot where people sit at different depths, or anything closer than usual, autofocus is the difference between sharp and nearly sharp. Look for "AF" or "autofocus" in the front camera line. If it is absent, assume fixed.
What to look at, in order.
- Does the main camera say OIS? This is the one. Everything else is secondary.
- Subtract the fillers. Remove every sensor under 5MP. Count what is left.
- Does it record 4K? Rear and front are different numbers. Check both.
- Does the selfie camera autofocus? If the sheet does not say AF, it does not.
- Only then look at megapixels. By this point it will tell you almost nothing new.
None of this tells you a phone takes beautiful pictures. Processing, colour science and the particular sensor a brand chose all matter enormously and none of them are printable specs. What this check does is stop you paying for a camera that was assembled for the listing rather than for the photograph - and in this market, at these prices, that is most of the battle.
If you are shopping rather than reading, our camera phone guide under Rs. 20,000 applies all of this to the current field. And if the screen is your next question, the AMOLED versus LCD guide does the same job for displays.
OIS first, filler count second, 4K third, megapixels last. Judged on published specification. We have not shot with these phones and do not print image-quality impressions we have not earned.
