Not sure if this is accurate but my phone...white phone bought 2015-early 2016 my problem...i dropped it! means it beyond repair hey!? but message me back so i could jus save money to buy a new one!
Very hard to answer your question with so little to go on. can you elaborate on what is happening, does it vibrate or give any sound? do you get any display at all? have you tried charging it? removed the battery and put it back in then try to turn it on? as for it being an s2 I'd say that if any parts need to be replaced i'd just get another
