Roblox keeps crashing on mobile devices due to several reasons. One common cause is high memory consumption. When the Roblox client uses too much memory, your device may close the app to avoid a system crash.
Another reason could be the graphics settings. If the graphics quality is set too high, it can make the app unstable. Lowering the graphics settings can often help.
Running multiple apps in the background can also lead to crashes. These background apps consume memory and storage. Closing unnecessary apps can free up resources for Roblox.
Insufficient storage space is another culprit. Roblox requires at least 130 MB of free space. Removing unused apps or files can create the needed space and help prevent crashes.
Server issues can also cause Roblox to crash. Checking the Roblox server status and ensuring a stable network connection can sometimes resolve these problems.
