[AC Question]

Ever since my last updated my s6 edge on April 2017. My phone has gone weird. Mant of my apps gone white. Battery life draining way to fast. Lost all my auto corrections and history on typing and it replaced with the wrong words other than what I typed. Etc.
I hate my phone now. Is there anybody know how to undo my last update and lock it in that version of the os system?

Since the re-flash of an old ROM essentially results in a blank device, I suggest trying a factory reset prior to taking the risk of a re-flash. You will need to back up your data (whatever CAN be backed up anyway) before either process.
