    Does anyone know of a safety issue charging the Samsung Galaxy S7 Phones that would cause Samsung to require software that wakes the phone up when fully charged to get us to unplug them?

    I've charged my Samsung Galaxy S7 Phone over night since I've owned it. After the latest upgrade however the phone lights up and beeps when fully charged, which then lights up the room while I'm trying to sleep. The notification settings for System UI are greyed out so that I can't turn them off. Clicking on the Battery Full Notification and setting it to "No sound or visual interruption" does not stop the notification from turning on the screen.

    For the first two years I charged the phone overnight using the wireless fast charger. Then the software changed and turned on the phone and lit up the room waking me up. Trips to Verizon did not help. Calls to Samsung resulted in them telling me to remove the phone from the wireless charger when charged. Samsung also said that "We do not recommend that you wireless charge over night" and "we recommend you unplug the wireless charger when charged". Waking up and removing the phone from the wireless charger when fully charged didn't work for me so I stopped using it. After additional updates the wireless charger no longer works. A brand new charger did not work either.

    For the past year I've been using the fast usb charger to charge the phone. But now, after another software update, the phone is waking up with a notification that the phone is fully charged. A trip to the Verizon store resulted in the technician not knowing that this notification is now occurring while using the usb charger. He did know of the issues with the wireless charger. I have not called Verizon customer service nor Samsung yet. Not looking forward to hours on the phone and getting past their phone answering service.

    We only have cell service, and I don't have access to charge the phone during the day. Charging it at night is what I want to do. But is it safe to do so? Or does Samsung know that there is a problem and changed their software to keep us from charging the phone over night?

    If its unsafe to charge the S7 overnight, then in my opinion the phone is unsafe to use at all. Are other S7 user's having safety issues?

    Here is a link to my original posts and things we have tried to turn this notification off.

    It's not unsafe if you're using legit chargers. The screen lighting up is standard behavior for Samsung phones for a while, I'm actually surprised you didn't have it or noticed it before the update (if it's a carrier-branded phone that might be why as carriers CAN tinker with the OS).

    There are 3rd party apps that can remove this, however, and I don't think they require root. I believe Lightflow allows this? Not sure as I've never used them...

    But anyway, nope, it's not unsafe. The battery and phone and Samsung chargers have all security features built in to prevent 'overcharging' or overheating so they switch to a trickle charge if you let them plugged in.

    Abassador; I'll look for an app to disable the notification. My laptops don't wake up to tell me that their batteries are fully charged. In fact they have no notifications unless I log in. Unlike Android which wants to tell me everything its doing.

    I would really love it if my phone did not require any notifications nor updates. Then I wouldn't have to waste time looking at it unless there was a real phone call. And it would just keep working. Instead of now, like how it doesn't work in my car when its in my pocket. Though it used too. Android is just too complicated I guess. My Wife's iPhone does not wake her up when it's fully charge and still works in all our vehicles.

    You may need a new battery to solve your wireless charging problem.

    The tech at the Verizon store told me the same thing. However my battery lasts over two days. Would last longer if Verizon stopped all the Spammers with phony phone numbers from calling.

    Why would I want to replace a battery that lasts two years? I assume Samsung doesn't test that their software works with three or four year old batteries. Though they have enough PhD's working for them maybe one of them needs something useful to do.

    Or maybe Samsung writes their Updates so that they explicitly will fail with old batteries to get us to buy another new one. I hope not.

    Needless to say when I need a new battery I'm dumping my S7 for good.
