How to buy used smartphone

 When we buy a used smartphone, we often don't check it properly. We buy an expensive phone at a low price; after we use it for a few days, we have to face lots of issues. 

How to buy used smartphone 

So don't worry; I am going to share with you some processes on how you can buy a used smartphone....

How to buy a used smartphone

When you are going to buy a used smartphone, you have to do some things, like set up a budget for buying a used smartphone. And you have to research online; like on social media platforms, you can check the present price. I bought a Realme C17. I used all the methods, which I will share with you further into this article...

How to check a used smartphone?

When you are going to buy a used phone, connect your phone to the internet... And go to the Play Store and download an app on your phone doctor plus



  1. After opening the app, you will see a "play button"; click on it.

2. It will check all functions like networks, memory capacity, CPU frequency, and write speed.

3. checking vibrator, This app will check whether the vibrator is okay or not. When we buy a used smartphone, sometimes the problem of the phone dropping from hand vibration appears.

4. You can click "list" and check all the functions if there are any options left. You can check one by one...

So when you buy a smartphone, you can check all the functions like this. Sensor-related, display all these as okay or not. If the phone dropped from the hand, then it might be a problem for the future, so you don't have to do anything. This app will automatically check all the functions...

You can check some extra things like

1. Phone display, screen.

2. Check if the phone fingerprint sensor and face camera lock are working or not.

3. Check the volume button and power button.

4. Check camera.

Check these options manually. Sometimes the application may not work. So if you check manually, it will be good for you....

Check smartphone output

If the phone is dropped from hand, then there might be a scratch. Whether you buy a scratched smartphone or not is completely your own choice. What is more important is that you will see a camera house. Check that there is any sand. So ignoring that type of smartphone is a clever move for you. Remember this point when you are going to buy any smartphone.

Check earphones and microphone

Check earphones and microphone. Check these two functions properly. You can call your friends and see that you can your friends properly. Also check that your friend can listen to your talk. Try with one or two different types of SIM, and obviously keep the SIM in both SIM slots. Sometimes, there are lots of smartphones where the SIM 1 slot is working, but the SIM 2 slot has a network problem. This thing happens when a smartphone drops from a hand.

Check if the phone is official or unofficial

Check whether the phone is official or unofficial. Mostly, the official phone has a 1-year warranty. If you get 2 or 3 months, then that will be beneficial for you. But I give you a little suggestion for an official smartphone: if the official phone is 2 or 3 years old, then you should avoid buying that phone; it will be a clever move for you. But if you want to buy, then it's up to you. An unofficial phone has no warranty or guarantee, but you can use it for a long time. I am not saying you should buy an official phone, but you can buy one that is not too old; it will be good for you.

Check the phone IMEI number

Now the biggest decision is whether you are going to buy that phone. I think you know how to check the IMEI number. If you don't know how to check that, dial *#06# on the phone and check it. Check if there is any smartphone box. And if there is any original charger available in the box. If the original charger is not available, then you have to buy it from the market, which is quite expensive for you. and try to get the phone buying receipt. Suppose you lost your smartphone and also the IMEI number. If you have a receipt, you can complain at the nearest cyber security office.

Check RAM and storage performance

Check the phone storage. Whether your phone is 64GB or 128GB. Run multitasking to check the RAM performance. If possible, play a YouTube video or play games...

Take All the Information

From whom you are buying the phone, take the address, phone number, and Nid card or passport copy. You have to maintain all these to buy a used smartphone; otherwise, you could get in trouble.

How to check the phone price range?

Sometimes we want to buy a used smartphone but don't know the price range of that smartphone. So you can check the price on Facebook Marketplace, eBay, etc. You have to research a little bit, and you will get an idea. Take some time and research it; which price is the best-selling? That is the real price, so try to buy a used smartphone around that price.

Check phone battery

How's the battery health? How long the battery will give performance is hard to know. So, one thing you can do is when you are going to buy that phone, use it for at least 20 minutes and more. Play some games and check if the battery heats up fast or not. Click photos continuously, and then you can see if your battery is draining or heating up fast, yes or no.

Where should we buy a smartphone?

We can buy smartphones from local market shops, the Facebook Marketplace, or from trusted people with good reviews. From where you buy it, you should look at all the functions that I told you about in this article.

Is it safe to buy an old used smartphone?

When you are going to buy a used smartphone, then you have to look up the phone carefully and check all the functions.... Is there any problem or not?

Do old smartphones get slow?

If you buy a 1-year-old smartphone, then you might get good speed. If the phone has been used for 3-4 years, then it might get slow...

And at last, see the phone outside Outlook. This is also important. A smartphone outlook plays an important role because you are paying for it...
