camera quality
Camera is the most important thing in the
smartphone, so watch the photos with the camera. Check that there are no
scratch marks on the camera lens. In addition to the screen button, drag the
photo with the physical button.
Physical
condition check
This is the most important condition before buying
any old phone. Check the phone separately to see if there is some damage from
somewhere. There is no breakage in the screen and its surroundings.
Check
phone warranty
Nowadays people have started changing the phone very
fast and accordingly, new phones are being launched every day. If you want to
purchase an old phone then try to buy a phone which is not too old and is in
warranty
Check
the function of the touchscreen
Nowadays all smartphones are touchscreens, many
times the touchscreen of the new looking smartphone also does not work
properly. So check it well before buying. Try twisting your fingers on the
screen. If the smartphone has a physical keyboard then try typing all the words
from it.
Check
all ports
Many times the ports become poor or loose in the old
phone, so check all the ports of the phone. Put the headphones in the
headphones port and see the sound is recovering. Also check whether the
charging port is working properly or not and the port is not loose.
Also
take the bill and all accessories
Check all the accessories with the phone and the
most important thing is the phone bill. Be sure to bill it when buying a phone.
If the phone does not have original accessory, you can speak to reduce the
price of the phone.

buying smartphones from overseas

older smartphones from foreign websites but keep in mind that many mobile phone
companies do not guarantee or warrant on phones sold abroad. You can check the
