Pros and cons of buying used phones
Advantage
Firstly is cheap, most of you buy used machines for this reason. For example, you can buy a phone you like with high configuration in that price range, if you buy a new device, it will not be very satisfied.
Monday It is possible to experience a super product with a mid-range price. Simply put, if you are looking forward to using the super product Iphone 11 Pro, then try to wait another month or two, the giants buy the experience and then sell it again at a discount price or can wait until next year, the Iphone 12 will be released at this time. This Iphone 11 Pro you’ve been waiting for has been heavily discounted already. Enjoy the super product experience.
Tuesday, that is the old machine less depreciating. For those of you who often upgrade or change machines, you should buy an old machine because it is less depreciating. Why? For example, if you buy an old phone after reselling it, it’s still an old phone, the price is still the same or it’s down, it’s only insignificant in a short time. And if you buy a new machine, why don’t you just buy it and return it to be old and its price is much lower than when you bought it new.
Defect
First need to know about the phone. Surely the person who wants to buy a used phone must have a little experience with the phone to be able to check all the features of the device to see if it works smoothly?
Monday, Short warranty period. If you buy an old phone, people use it first, of course, the warranty period is very little. If you buy an old product that is more than 1 year old, it will no longer have the company’s warranty.
Final That is the encounter with poor quality goods. As you all know on the market now, there are many types of fake fake goods, and especially if you buy old phones at unreliable stores, it is easy to stick to the above machines. So you must know how to check your old phone to avoid meeting a beautiful phone with damaged components.
Experience in checking the device when buying a used phone
How to check your phone when buying used is something you need to know. Because there are so many types of machines and models, I will generalize all types of machines. How to check the old phone is suitable for all types of touch phones such as old Iphone, old Samsung, old Xiaomi …
The first is Check phone appearance
Check the Imei in the device (go to “Device information” or go to “Phone” and press *06#). Pay attention to see if Imei on the case, paper box, device overlap? If not, it has been replaced. But you can also guess why you have to change the cover.
Check carefully around the machine is there no scratches? Because those are the traces when falling and hitting that fall and break. The possibility that the sealing component inside will fall out anytime it likes.
Next, insert the SIM card into the device
This part should also be tested first because everything else is OK, but it takes a lot of effort when you return to listen to the call back.
Check if the phone signal is up or not.
Next, call someone (Don’t waste money, call 900) call to check if the mic speaker can hear clearly. Always check the proximity sensor. Raise your hand to cover the top of the phone where the speakerphone sees that the screen is dark, the sensor is OK. That is so that when we bring it to our ears, the screen turns off to prevent unnecessary touches from affecting the call, but we have to leave the speakerphone so that the speakerphone can’t be turned off.
This part should be tested carefully because I bought a phone to listen to calls, but many phones it’s first call, it’s broken, then it’s a waste.
Now comes Wifi, Bluetooth, battery charging
Plug in the charger, depending on the charger and battery capacity, but about 2-3 minutes to 1% is fine. Plug it in and don’t see it, then take another one.
Next, go to turn on Wifi to catch a certain network, I also use it a lot. Once you get there, turn on Bluetooth.
If you have an internet connection, go to Youtube and open a song you love to see if the speakerphone is loud and clear. Then plug in the headset and listen to see if it recognizes the headset.
Check Camera and Microphone
Turn on the Camera, my friend. First check the focus, Press on the dark areas on the screen. For example, if you press on a dark place, it will light up and see where you press, press on the light and it will darken, that’s OK, and your camera focuses well.
When done, switch to video recording, press “record” and then “Alooo!!!Blooo!!!” a few times and then open it again to see if the voice I just said is clear. Remember to shoot both front and rear cams. (Turn over to the front cam and think you’re ugly, try “A!!!Eh!!!” a few times to check the Mic cam first.)
Test touch and screen
It’s very simple to press and hold on an Icon to move around the screen. If the Icon falls anywhere, the phone’s touch is dead, so change another one.
Go back to open Youtube screen test video then play the video for about 4 minutes. Remember to pay attention to the battery percentage, then turn on auto-rotate and then turn it horizontally to see if it automatically full screen to test the gyroscope. If the whole screen of one color shows a dot of a different color, the screen is dead pixels. After watching, look at the battery percentage again. Because after 4 minutes of watching Youtube, it’s OK to get down to 1% of the battery.
Test hardware keys, fingerprint and Face ID (face recognition)
There is a button on the machine that you can push or push, just push it all. If swiping and pressing it does something, it’s fine. For example, the iPhone’s sound button, the volume up and down keys, the power button.
Old phones often lose fingerprints, Iphone has Face ID error. You also need to fully test these features before purchasing.
Check account
This doesn’t seem important, but it’s incredibly important. With IOS, it is even more important, you need to tell the seller to log out of the Icloud, Samsung, Mi Cloud accounts from the phone. Then manually reset the phone to its factory condition. Then manually log in with your account.
In addition, you should also equip yourself with the knowledge of checking old phones network locked are not? For iPhone, if you buy a Lock product, you must use a paired SIM to receive the signal.
