I'm trying for two days to find a solution for this problem. None of my researches have been successful. I tried Intel Android drivers, uninstalled from SDK Manager and re-installed Google USB drivers, changed MTP to media option, used stay awake screen option, and tried to manually install drivers. The OEM drivers that the Google page links to for Lenovo are broken. It's also in Chinese. Even when using Translate, there is no download. I changed the fast charge cable with a standard one and the connect/disconnect cycle stopped suddenly. But Android Studio still doesn't recognize my phone.
It's unexplainable for me that how there is no fix for this issue. Since there are millions of apps on the Play Store. Google needs to fix a lot. Most information even on their pages are outdated and have spelling errors. I'm sick and tired. İ own a Lenovo G50-70 with windows 10 x64.
