"Why does my screen go black when the phone is too cold?"に関する回答In case you tried everything and for some reason you still need to use your S7, alternatives to screen fix: -Cast your screen to chromecast. You can see the whole screen on your TV. -Charge your phone during the night, and place it over your router without case. In the morning you screen will work for an hour or so. -Enable second screen option simulator: Enable Developer Mode (Settings - About Phone - Click build number many times) In the screen/video section, enable screen simulator. You can see a small, real-time second screen and place it where your physical screen still works. In touch section, you can enable a feature to show where your fingers are in the touchscreen. This also helps.
