    Here is the situation: My phone (Samsung Galaxy Note 4) turns on and works perfectly fine if I am do not click on any app.

    Then say I click on some app. If I try to press too many things in too short an interval of time, then my phone restarts itself. Also if I clicked to turn on data or WiFi, then the phone reboots regardless of whether I select an app or not. When the reboot is complete, it displays a much lower battery level than it had when it turned off. Then it reboots again, and continues a few times until the battery hits 0%. Then I need to charge it up.

    (*) if my phone was plugged into a charger, then this does not happen - it never reboots, and never has any issues. But if I keep it plugged into a charger all day, it effectively is no longer a smart phone, but is more of a desktop PC


    What is wrong with this phone? How can I find out what is wrong? Can it be fixed? If so, how?

    Note: I am a novice, I don't know much about technology other than how to use my device for day to day stuff. It is not rooted or anything like that.

    Welcome to Android Central! The first thing I'd try is a new battery.

    I am the person that posted this question (but had not created an account yet at the time). I have experimented further with this, and found that the phone seems to work perfectly fine if I keep wifi and data off. The moment I turn one of these on and then try to do anything, the problem described above occurs. As a result of this discovery, I don't think your answer will solve anything for me, since the battery works well when wifi/data are off.

    Ok, then see if the problem persists in Safe Mode, in case some 3rd party app you installed is causing the instability: https://support.t-mobile.com/docs/DOC-28897

    Ok I tried this and it did not work. I held both buttons down, and the words "Samsung galaxy note 4" appeared as usual. Then the samsung logo began to appear. The first 3 letters, SAM, appeared before the phone rebooted back to the "Samsung galaxy note 4" screen.

    Update: I visited a Samsung repair store where they concluded it was a hardware issue (I forget the specific word they used).

    If any future reader is interested, this replacement would cost £200, so does not represent value for money in my opinion.
