Enable Memory Cleanup

Your Phone may slow down over time as your storage space gets smaller. Use Memory cleanup to free
up storage space, improve system performance, and keep your Phone running smoothly.
Open Optimizer, then touch Cleanup to clean up memory and clear the cache to optimize
performance. If your storage space is still low, perform a deep clean to free up additional storage
space.
