USB connection is not working while my phone is ON
I am presently facing a strange issue with my Honor 6. Nothing has gone wrong on my phone for almost 1 year but recently, impossible to charge my battery while my phone was on. Today, after a few weeks thinking my phone was just dieing, I have tried to make a back up and wanted to save all my data on my computer. However, impossible to connect my phone to my computer. Then I realized the problem was probably due to my USB parameters (No interface asking for mode to choose when I plug USB).
I finally did my back up but issue is still there : I can only use USB while my phone is OFF... meaning I only charge my phone when it is OFF.. :-(
I did not find any solution on internet and did not find an option to allow this interface to come back, even by trying to go in "developer options"
Could you please help?
Is this a good question?
