Does running apps from android studio causes harm to device?
In one word the answer is NO . But it could be if your device ROM is not an official release. Many of us use local phones from different local company, most of them use unofficial release of android OS and their OS structure is not stable. thats why some of us face issues like Wi-Fi not working , Bluetooth not working , Heat issue , Cache memory issue , Auto recovery mode etc. Simply using device to check error logs and verbose loggers to optimize or edit your apps is okay if you don't go for any OS related modification and voltage modification on your device.
