There are a few things you can try to stop your CITYCALL I8550 from freezing up:
Restart your CITYCALL I8550: This can often resolve freezing issues because it closes all running apps and clears the memory.
Update your phone's software: Make sure you are running the latest version of the operating system. Outdated software can cause performance issues.
Check for app updates: Make sure all your apps are up to date. Outdated apps can cause performance issues.
Free up space on your CITYCALL I8550: If your phone's storage is full, it can cause performance issues. Try deleting unnecessary files or uninstalling unused apps.
Factory reset: If none of the above steps help, you can try a factory reset. This will erase all data on your phone and restore it to its original settings, so make sure to back up any important files before doing this.
Contact your phone's manufacturer: If the issue persists even after trying the above steps, it may be a hardware issue. In this case, it is best to contact the manufacturer for further assistance.
