    Hello,
    Thank you for the reply. I have been registered now.
    I checked every settings related to the screen or the display. I restored the phone factory settings and the issues still there. Another thing I noticed that I can turn it off if the phone is plugged on power. otherwise I can't turn it off at all, and it consuming the battery too fast.

    Welcome to Android Central! Are you saying that when you press the Power button, it goes to the lockscreen instead of putting the screen to sleep?

    Hello,
    Yes, indeed. when I press the power button it locks the screen but it stays on even if I click it many times. Also, when it's plugged the problem is solved !!!
    now I try to fake the plug, I plugged the cable to the phone without plugging it into anything to charge, and the problem is gone. but as soon as I unplug it it goes on again !!

    Hi @mustang7757,
    I didn't try yet the safe mode now, because the problem is gone suddenly ! For now it works fine, but I have doubt that it might go back. I'll leave this question open in case it happened again, and then i'll try the safe mode.
    Thank you guys for helping. This is much appreciated.

    I'm wondering if you have a dirty or bad charging port.

    This was exactly my thought. If plugging the device in, even without power, causes everything to work it sounds almost like there was moisture in the port of the phone. Like two legs of the port were crossed and plugging it in broke this circuit and allowed the device to act normally. This would also explain the rapid battery depletion. I might have expected the device to be warm or even hot due to this as well.

    If it were my device I would check the phone port, maybe blow it out with some compressed air, and definitely check it if it begins happening again.

    Yes, There is definitely something within the port. Cause it come and go randomly. Should I try to blow in it with a hair dryer (Cold air of course) ?

    You still have warranty or insurance?

    Be careful with heat. Although the issue may be moisture blowing hot air on a device can cause physical damage. Over heat the battery and it will shorten the life of the battery. Over heat the seals and the device may affect or lower its IP rating. Stone of the plastic within the device may melt or become distorted and cause other internal issues. Your best bet is to get a regular can of compressed air, like that sold in electronics departments just for things like this.

    You also want to be careful attempting to charge or use a device of there's suspected moisture issues. Electric and moisture/water don't mix. A relatively minor short circuit can have major impacts on circuits and chips.

    Begin but assessing if the issue could be moisture. Was the device in a pocket when you were particularly sweaty, near a steamy pool or shower, in any situation where moisture or condensation could have occurred?

    Next actually look in the port. While debris is often easy to see moisture may not be but taking a peek may give you an idea of what you're up against. If you find debris try gently rapping the device on a table, don't get too aggressive. It will either fall out or it won't and if you've plugged the device in it may be wedged but you should approach this like saving someone from the water. Reach, throw but only go if you absolutely have to. If reaching, tapping, doesn't work. Then throw some air down there, in the form of compressed air from a can. A blow dryer may seem to be throwing air at it but that's very low pressure defused air that will only serve to hear things up, which again is dangerous. Finally if it's truly wedged in there and tapping and blowing isn't working, very carefully go. A toothpick or disposable floss pick might work. I can't stress enough to be gentle. USB-C ports are rather large and getting in there won't be difficult but trying to force something can be costly.

    If you didn't find debris and there's a chance it could be water, set the device side for a while. We're all attached to these things and wonder what life was like without them, well if you really want to know continue to use a wet device and you'll find out very quickly. With the device off, place it in a moderately warm place, near a window (but not in direct sunlight), on top of a PC or something like that and let it sit. Stone may say try rice but I read that rice is only truly effective if it's in contact with the moisture and we don't want to shove rice in your phone. It mostly just makes people feel better. Having it in a dry sealed environment is good but rice doesn't speed up the process. If we're talking moisture we can't see 12 to 24 hours in the right environment may be enough. Obviously the more moisture the longer.

    Check back and let us know what you found, didn't find or suspect.
