Hey all new here. Will i get used to this phone ? Had it for 7 hours, and struggling so far. Prevous phones were nexus5, 1+1, nexus 6p. This is my first samsung. Why is the back button on the right, can i change this? Second issue ive found is the favourites in messenger, phone app and edge favourites don't sync? I might be a little biased but i acutally think the nexus6p is quicker?
