why does my screen suddenly go black when I'm in the middle of doing

[Android Central Question]

I was running out of memory and so I went into settings and change some things after that the screen suddenly started going black when I was able to finally get it to a double screen with black up top and my messaging or whatever I was doing at the bottom I discovered that the black screen was my maps app

Welcome to Android Central! Which phone? What settings did you change? Go to Settings>Apps, select Maps, then Storage, then Clear Cache/Clear Data. Now open Maps again. Does the problem persist?
