I had a s7 edge and it was rooted so I couldn't use some apps due to that I had to install a software so that it can go to official. After installing the software my phone has slowed down. The performance is not the same as it was before. Plz tell me what do to make my phone fast as before

What was the software that you installed, and from what source?

[Humza Sohail]

I went to a shop and he installed the software for me. After installation was complete my software came back from nouget to marshmallow and then i updated it back to nouget

So we're talking about unknown software.

Idk maybe but he said it was authentic

[Humza Sohail]

So r u going to say something?

[belodion]

Me, or the membership in general? My knowledge of Samsung devices is minimal, but since no one else has replied, my only suggestion would be to reflash the stock firmware. You would need a PC, and I believe that the software that you would have to download to it is called Odin. I imagine you would need the Samsung drivers as well.
I'll move the thread to the S7e forum, whose members will know about these things, or will perhaps suggest other things.

Well, we don't know where he got the software. It's easy for the person in the shop to say it was authentic, but it could also have been not, or tampered, or simply it was a version that wasn't fully compatible.

Personally I'd just tell you to learn to do it yourself and get the firmware copy from Sammobile.
