The Oneplus 3 "pocket problem"

    Hi,

    there have been more and more people posting about the same problem:
    When the phone is in the pocket with the screen facing towards the leg, heavy cpu usage, battery drain and heat can occur.

    This is because of the fingerprint sensor constantly scanning. It should be deactivated by the proximity sensor, but it isn't. (This can be tested easily. Just cover the whole phone with your hand or put it up to your ear and then put your finger on the scanner. It should do nothing, but it actually does!)

    This has nothing to do with the ambient display or display gestures, because it also happens when everything is switched off.

    Here are several threads with people reporting the problem:

    Is someone from Oneplus reading this? Please try to implement a fix in the next OTA software update!

    UPDATE (2016-07-26): The pocket problem was addressed in the OOS 3.2.2 OTA update! Thank you Oneplus for listening + fixing this!

    Interesting, thanks for all the info.
    I always wonder why people have this issue but now I know, I wear usually trousers with thicker pocket material.
    I tested the scanner through a t-shirt and it vibrates, two layers nothing, two layers a bit wet and it vibrates. But when it is off it doesn't do this.
    How can we be sure that this is the problem?

    I just experienced this myself. I took my phone out of my pocket and noticed it was really warm. My battery had gone down from 100% to 92% after a 30 minute commute to work where I did not use my phone at all.

    Please fix this!

    Would you pass on the information to the concerned developers?
    For me support chat were not ready to accept that this is a common issue among OP3 users.
    Told me that i should get the device replaced asap...
    Hopefully because of you the issue will get noticed by the developers.

    The issues needs to be fixed asap...

    Or turn of fingerprint sensor and use another form of security ie password or pattern until next update then install update and reactivate fps to see if issue still exist.

    I have this same issue with my OP2 but only since the latest OXY update.
    My OP3 is on the way, it's a shame to hear this is an issue still. Tempted to order a flip cover but really don't want to as it's so detracting from the user experience

    I experienced the same issue. I left my OP3 in my laptop bag all day turned on, and locked at 100% battery. At the end of the day, about 8 hours later, when I removed the OP3 from the bag the device was very hot, the screen was on, and battery was 20%.
    It should also be noted that the ambient display setting was turned on with 'turn on screen when device receives notifications'.
    This has happened 3 times until I turned off all of the ambient display settings.
    I still have the fingerprint sensor set as my security access method. I have not had this battery drain and heating problem since I turned off the ambient display.

    I'll receive my OP3 today, and while i was reading this, i realized i have the same issue with my OP2 (getting hot, battery drain, etc. when in my pocket). So i tried covering the proximity sensor and i can confirm the fingerprint sensor "listen" anyway.
    So it's more like an OxygenOS issue than OP3 itself.

    The issue is that the fingerprint scanner is always on rather than the screen wake function. Whilst the double tap can occasionally wake a phone, it's the print scanner constantly trying to read peoples thighs whilst in their pockets that's causing this.
    The problem is, for it to function as quickly and efficiently as it does when you actually want to use it, it needs to be always on, waiting for a print to scan. So the real challenge here is finding a way that it can distinguish between the inside of a pocket, and a finger/thumb tip without having to scan it.
