How do I fix the Samsung Galaxy S5 FREEZING AFTER UPDATING TO ANDROID 5.1.1 Lollipop? Ever since I installed 5.1.1 my phone locks up. It's like Samsung engineers purposefully sabotaged this update to force people to get the newest Samsung phone. The freezing happens several times a day with lots of lag. Facebook screen goes black, the keyboard takes a long time to pop-up, and words take a long time to show up after I type them across many different applications. I’ve rebooted my phone and cleared the cache several times. I had no freezing or lag issues before the update. This phone on paper is faster than the OnePlus One but is actually slower than it now. I am unable to root this S5 phone because Samsung's Knox security will be tripped.

I've taken the following steps to clear the system cache with no success:

  • Turn the phone off.
  • Press and hold the following buttons together: Power, Volume Up and Home.
  • Release the buttons once the Android system recovery menu appears.
  • Use the Volume buttons to navigate to Wipe Cache Partition option.
  • Press the Power button to confirm selection.
  • Select Reboot System Now option after deleting the cache.
  • Wait for the phone to reboot.

Should I just sell it on ebay? lol

You can always download the official earlier OS from Sammobile, and flash it using Odin. Since it's an official ROM, the Knox shouldn't be tripped.
