[Q] Note Getting slower since screen replacement

Hi,

I recently got the screen of my note replaced. I got it replaced from samsung service center. The display is working fine but the trouble is my phone has gotten really slower since the screen change. The touch seems non responsive from time to time, and the time it takes for an application to start has increased considerably.

Now I am just wondering is this issue really related with the hardware change or is it just a co-incidence.

Thanks a lot for help in advance.

Regards
