I have the same problem. Same, it is a Sandisk Cruzer USB. It happened suddenly, 1 day I decided to format and hope , enable to write, or write protected. During my research peoples, I read that it happen after using something like secure vault, or dont know what. but I never used that $@$* secure vault or dont know what provided by Sandisk. Another reseach told me that those Cruzer USB are faulty and should be sended back, they gona provide another one. Except warranty is gone + in my country no warranty disponible or Sandisk store. I tried everything, even GParted through DOS. Nothing works!! Never ever buy again a Sandisk or Cruzer product!! Luckily there is no data on it. My best guess, internal software need to be flashed back, with something through DOS, not through Windows, cause Windows is very poor for managing other devices than itself. Maybe by Linux. Unfortunatly I could not find anything over the net for this problem, most people say it is locked by the small Switch present on the USB, except...

I got the same problem, I need to open it, but arrived to the point where the cover is strongly held. I dont want to force to dont destroy it. did you finally manage to open yours?? Thx Edit: Finally I managed to open and repair it. it felt from my hand, and refused to work anymore. So decided to open and check the issue. I had to force a bit , nothing to complicated, but the clips were very tied, thats why anyone is scared to insist... Finally it was the negative pin of the battery that was cutted from the board, so just resolder it to the board, and it was good to go :)

Hello, I have the same problem as yours. The proximity sensor is crazy. During *#0*# test, for the proximity sensor, proximity sensor test displays 1 and screen vibrates constantly and always is green , exactly like you described. I have a samsung S7 Edge. During calls, the phone screen turns off without holding it to ear! In WhatsApp calls, I can not even hang out because the screen freeze completly! At first, I thought that it was related to the Roms, I tried a few, and even the Official from Samsung got the same issue. So with the result from the sensor test, with *#0*#, I am (99%) sure that proximity sensor is guilty, and plan to change it. But how can it have been damaged?? kind of wierd. How didyou resolved the problem?? did you changed the sensor?? Thx for any feed back, and recommandations.

Hi, my Tab S 10.5 got dicharged, and turned off as it should when any device gets discharged. Next day I recharge my tab, any now the screen is no more responding. The home, Recent App and Back bottons are working, but the touch screen is no more responding, so I can not even slide on the screen to unlock the Tab.

PS: my tab did not even feld down. Have been very carefull from when I got it.

Any idea what it can be?? Can it be related to the MotherBoard or the screen itself?? Its
