Clear cache first
Go to Settings, Apps, the app, Storage, and tap Clear cache. Crashes during streams are often a corrupted cache entry the player trips over. Do not clear data yet; cache is the gentle fix.
Free up memory
Close other apps before a match, especially games and camera apps that hog RAM. On phones with 2 or 3 GB of RAM, an overloaded memory is the top crash cause. A restart before kickoff gives the stream a clean slate. Streaming apps also compete with background downloads and cloud backups for bandwidth, so pausing those during a match helps twice: fewer crashes and less buffering.
Reinstall the build
If crashes persist, uninstall and install the APK fresh from the Yacine TV Black download page. Damaged files survive cache clears but not a reinstall. The not-opening guide covers launch crashes specifically.
When the phone is the problem
On very old or full phones, the OS itself kills background apps aggressively. Free up storage, update Android if you can, and check the update guide to make sure you are on the latest tested build. Turning on the data saver can also backfire during streams, so whitelist the app in the data saver settings if you use one.
