Take a look at the old mobile purchases which will be seen

1. First you will see the phone is real or fake

For this, see the phone's IMEI * # 06 # Then check on that phone's official web.

For example mi mobile https://www.xiaomibangladesh.com.bd/IMEI/check_imei

You can also use it for all phones at http://www.imei.info/

Check these two phones as real or not.

Samsung * # 0 * #

Nokia * # 0000 #

1. Check the phone's performance
   Download this app and install it on that phone.

AnTuTu Benchmark apk

You can learn a lot about the phone and about the phone. RAM, battery, and processor will show these.

Then the total performance number will be shown. Of course, it does not matter what's on 20, 000.

This will be able to purchase a good phone. Also, refrain from purchasing the phone without seeing it. Avoid engaging advertising. Avoid unreliable websites.
