After resetting my phone, I can say same about my S6 Edge under Lollipop. Fingerprint unlocking works faster than ever, almost no delay when entering phone app or messages etc. Resetting a phone helps restoring something we are forgetting with time : original smoothness.I dont miss any feature of Marshmallow because I talked with some buddies of mine when it got released, we compared features and there was nothing which could attract me.Reading many forums and comments about the troubles possible didnt help either.I also have updated my S5 to Marshmallow, theres hardly a difference with it under lollipopso this nailed the subject for me.And beyond that, I had made a topic on issues to solve for S6 Edge on sammobile which seemed to be one of the closest from Samsung. But I guess, its barely a one-way site.
