How to Fix Galaxy S6 Performance Problems

Samsung Galaxy S6 users experiencing abnormal lag or sluggishness will be happy to know that there are an array of fixes to try and help stabilize the performance of TouchWiz and Lollipop.

The first potential fix that we recommend is a process that will clear the Galaxy S6’s cache partition. To clear the cache partition on the Galaxy S6, follow these steps:

Turn the Galaxy S6 off.
Press and hold Home, Power and Volume Down buttons simultaneously until the device vibrates.
When the Samsung logo appears, release them.
Tap Volume Down repeatedly until you Wipe Cache Partition. Select it with the power button. Select Yes.
Wait for the process to complete. It could take awhile.
Reboot your Galaxy S6.
