The camera is one of the most sought after features for smartphone users. When it comes to camera performance, focus less on the megapixel count and more on features such as image stabilization, aperture, lenses etc. 

What about 5G?

It is the latest technology for cellular networks. The deployment of 5G has started in select countries. However, the commercial launch of 5G or fifth-generation wireless technology is still a few years away in India. We think you should not be jumping into 5G yet.

iQOO and Realme have already made their 5G smartphones available in India. In the next couple of months we can expect the launch of more 5G ready smartphones in India. 

New Vs Refurbished smartphones 

Buying a used smartphone could save you some money. These days e-commerce majors such as Flipkart and Amazon provide useful choices in refurbished smartphones. Certified refurbished smartphones are available in various grades in different budgets. The refurbished products go through a rigorous checking process. Buying a refurbished smartphone makes sense if budget is a concern or you want to use it as a secondary device. 


Tips for Buying Refurbished Smartphones

If you are planning to buy a smartphone on a budget, then you may want to buy a refurbished smartphone instead of a new one. However, buying a refurbished smartphone is a bit tricky. You cannot just  go and make a random purchase without even checking the condition of the old phone thoroughly. 

You might get a used smartphone without any scratches on it, but you have no clue that maybe its internal hardware issues. That's why it's really important for you to avoid this kind of smartphone for your own good.

Most people think that used smartphones are not good enough. Well, the truth is, some of this type of smartphone still works just as great as a new one. So it's irrelevant anymore to say that the quality of second-hand smartphones will be that horrible.

Well, if you have made the final decision and are perfectly sure that this is the right time for you to buy your first ever used smartphone, then these are 15 useful tips that hopefully can be your first guidance every time you're planning to buy used smartphones in the future.

1. Run a Quick Scan on the Case Cover

The first thing to notice from a smartphone is definitely its case cover. Therefore, every time you meet some used smartphones on any store, make sure that you always run a thorough scan of the device. Try to see if the device has any physical defect or scratch around the body of that device. This must be done in order to know more about what that device has been through in the past when it was still used by the previous owners.

2. Make Sure that the Case Cover is Original

Used smartphones are usually plagued with the perception that their case covers will tell you the whole thing about their condition. Well, that is so wrong. You cannot judge the overall quality of used smartphones just by looking at how glossy its chassis or how flawless its screen. There is a huge possibility that the seller already covers them up with some new 3rd party case covers that obviously will make them look like new phones, right?

3. Test the Sound Quality of the Speaker

Making a phone call is the reason why the cell phone is invented in the first place. Without it, your phone shouldn't be called as a phone. That's why, if this feature doesn't work properly, then your used phone will be useless in the future. So it's also really important to always run the test of this feature by making a random call on other devices and hear if there is something wrong with its sound quality, signal or its loudspeaker.

4. Make Sure the Physical Buttons Work Perfectly

Physical buttons always become the fragile element on any smartphone that tends to be damaged easily if they have been pressed so many times by the owners. That's why, when checking out any used smartphone on the store, always make sure that all the physical buttons, remember, all of them, can work perfectly, without any hiccup. The best thing to do that is by pressing each physical button over and over again. If you see that there is any button that gives a weak or delay response (sometimes it works, sometimes it doesn't) or even doesn't work at all when you press it, then the best

5. Check the Screen Sensitivity 

The next thing to check from a used smartphone is the screen surface and the sensitivity of its User Interface. In this process, always run a thorough scan if there is any scratch around the screen and make sure that the touch screen still works perfectly. Test the touch response from each corner of the screen until the middle area. Do some mixed and random gestures on the screen over and over again, from:

5. Check Colors Reproduction on the Screen

Besides its sensitivity, the other important thing to check on the screen is the display. Usually, used smartphones have been dropped for several times by the previous owners. Therefore, it's really important for you to see the whole area on the screen to check if there is any glitch or weird line on color reproduction around the screen. If you see any of these, then the screen is not fine.

6. Check Battery Condition

There is no doubt that battery is one of the most important elements in smartphones. Most touch screen phones, even the new iPhone, have weak battery life (with the exception of Samsung or Motorola flagships of course). Therefore, it's really crucial to always run a test on this sector every time you want to buy used smartphones. To name of few, you can do things like playing high-performance 3D games or watching movies/videos to make sure that the battery is still in pretty good condition, if not great. If the battery drains pretty quickly even when you just open the photos or listen to some songs (which are not really energy-consuming activities), then there is something wrong with the battery.
