Since I upgraded my Samsung Galaxy S8+ to Android 9 Pie, it slowed down significantly. Most noticeably:

  • Text to Speech on Moon+ Reader Pro 4.5.7 has slowdowns and noise when in standby, formerly it worked perfectly
  • Web Pages are very sluggish in Google Chrome 73.0.3683.90

How can I restore the old speed on my phone without going back to Android 8?


  • Kernel-Version: 4.4.111-15668116
  • Model number SM-G-955F
