arekmoja, Oct 6, 2016 : Hi.. I also have the same problem. This morning my OPX was freezed and constantly launching notes "Oneplus Launcher is not responding". With the suggestion from the forum (https://www.reddit.com/r/oneplus/comments/54r6mg/tech_support_oneplus_x_launcher_not_responding/) I did the data wipe action and reset my phone again. Thankfully it works, but unfortunately now it seems that my speakerphone is not working, either for multimedia (music & video) nor the calling activity. But the audio jack still working, since I could still hear music and video through my headphone. I have rebooted my phone several times, but the speaker still not working Are there any solution to this? Please help. Thank you..
