Remove corrupted applications

Free software, which can sometimes be bundled with malware, can cause the system to slow down. Removing such software help your device return to the normal performance level.

If not, we recommend resetting the system. If the problem does not occur immediately or within a specific timeframe, that can mean a number of problems combined together are slowing down the system. If this occurs, we recommend resetting the system.
