That lag you are taking too is caused by full memory, try trimming as much as you can of your apps and see... Better set a memory cleaner too to auto run when screen off, this way you avoid lag and still no restarts you might get stuck af5er a flash only...I am agree with u. my note has noticeable lag before it restarted itself and stucked. tried both lsa and lsc, but all are same issue.
