Gentlemen, I caught some mysterious bug. I use cable transmission extremely rarely, and I donвЂ™t remember when I did it the last time, but it did. The phone on the cable connection began to charge, no offers of choice of connection, no notifications, nothing. The other cable is nothing. The other comp is nothing. Got into settings. In connectionsUSB - disabled . And also inactive, that is, not included. Why is not clear. I tried to get into the developer mode вЂ” turned off debugging-turned on, turned off-turned on asking how to connect every time, chose a different and back connection by default вЂ” nothing helps. The phone also turned off, turned on. I donвЂ™t understand where to dig further, I donвЂ™t really want to do a reset. Phone rutovany, if it is important.
And the second question, since I started writing - I have several applications that should work in the background, but the phone вЂњkillsвЂќ them regularly. Some cope with this, some - no, and the one writes "the handler was killed." Considering that the functionality is tied to a one-time event, this is inconvenient and offensive. Along the way, when you restart the phone, not all of them come back from non-existence, although they should, but one application with nightly tasks does not do them at all, and does not write errors either. It did not start.
All this clearly has some common roots and they lead to energy-saving systems. In the Battery - start menu, all these applications are assigned manual control with the appropriate permissions, but this did not solve the problem. Where else to look?
Upd. Even fastboot devices also do not see the phone connected in fastboot mode. Either this is a coincidence and both cables are buried or similar to a hardware problem.
