P7 is great,
P8 is not very good ( Im being polite here), all I get is random crashes, and I have given up trying to get help from SM support team, all they do is ask for more info, and get this
an incident report will close after about four days  as problem solved, so you have to keep
requesting updates to keep the incident report open how crazy is that (lmao).

So I am still using P7 most of the time
