Could be either software or hardware . I tried resetting my phone and resetting calibration which didn ' t work , so I sent my phone in for warranty here in Hong Kong . They sent it back to me and it works now . If you can ' t send it back for warranty you might want to try a custom ROM . You should read the Le Max 2 forums over on XDA . Good luck . <| sep |> 4 am and around 2 mb <| sep |> God , I feel sick . Winner have been cursed from the start . They had so much potential , but YG always had to be so petty , treating them like a chip on his shoulder . I had hope Winner would keep rising , and have supported them as one as my favourite boy groups since pre debut favourite in general . Whilst that doesnt change . their future looks bleak . Also , this is the second Winner member to openly express having mental health issues since debuting under YG . Blaming it all on Taehyun is disgusting on his half , sad little man .
