Phone making too many devices

[gearsniper550]

I dont know why but for some reason whenever i bring up my device manager there are 20 different versions of my phone. I only have one and dont know why its doing this. Is there a way to delete the other ones at once or do i have to manually delete each one

Your phone will be set to use randomized MAC addresses which makes it essentially look like another device. Disable it by following this guide: https://www.howtogeek.com/722653/how-to-disable-random-wi-fi-mac-address-on-android/

Then on the Device Manager click the  icon and you can delete all offline devices, that will prevent the multiple devices.
