EMERGENCY ALERT keeping SCREEN ON for HOURS

[C0RTANA]

I am in Canada and they keep harassing everyone with regular "emergency alert" tests that cannot be avoided and/or disabled because they send them out as Presidential alerts.

At times I may not be around my device, and oftentimes anywhere from 5-8 hours may elapse before I check my phone (they always send the alerts while I am asleep). In other instances I may only check my phone 12 hours later - and in each of the those times the Emergency Alert has KEPT MY PHONE SCREEN ON for the ENTIRE DURATION OF MY ABSENCE!

SAMSUNG - please let us know - are these alerts DAMAGING our phone screens/hardware?

Is this criminal alerting system that cannot be disabled or bypassed in Canada literally BURNING our screens out??

How come Samsung themselves do NOT put the phone screen to sleep after an alert is received???

Why is the screen being kept ON for HOURS until the battery completely drains????

How is this healthy for the device and/or the screen itself?????

Help, Samsung!!

U find these alert "harrasing"

Sorry to Bother u with some Amber Alert

This is not about what my preferences are. And yes it IS pure harassment because our government sends ALL alerts, including tests... as Presidential alerts that cannot be disabled or avoided.

Now that we have concluded this is harassment, let's get back to the point of the thread:

As soon as one of these alerts comes in, it wakes the screen and keeps it on until the battery is drained (given that no one checked their phone after the alert was received). There is a real concern that the phone screen and/or hardware is getting damaged from this.

My thread is simply asking whether these worries are warranted or whether the screen can handle being on for up to 24 hours without turning off?

Our government sends even test alerts as Presidential - there is NO way to disable and/or prevent them from harassing us.

There's no "presidential" alert in Canada.

You sound a bit off... 🙄 

[C0RTANA]

I don't care what it is called in Canada. If it can bypass all alert settings - which the alerts that our government sends out can - then it is Presidential to me.

Use your brain please.

It is not about the title of these alerts.

It is about the FACT that they can BYPASS all alert settings and still be received - whether it is a test or AMBER alert - it still comes in. And on top of that, each of these harassment alerts wake the screen and keep it on for hours (the original question I had was whether the screen is being damaged by these alerts or not).

The only one who sounds 'a bit off' - is you. Leave my thread please, you are a complete waste of time.

There's a schedule for the Alert Ready Tests. Rather than crying like a paranoid, conspiracy theorist. Turn off your phone when there's a scheduled test. 

No, it's not going to damage your phone.

You're posts are the waste of time... 🙄 

[C0RTANA]

My posts contain a valid concern in them.

And I'll say it one more time: it is not about the alerts that I care about. I am wondering whether the alerts waking and keeping the screen ON for hours (given that the phone cannot be attended to) is damaging the screen itself.

So far, there has not been a proper reply from Samsung to let us know whether this adds wear on the screen and/or speeds up the deterioration of hardware.

You're not likely to get a helpful response from Samsung here. 

Have a look at this information:

"

Leaving your phone on the same screen for an extended period, such as 10 hours, can potentially cause screen burn-in or image retention, especially on OLED displays. This issue occurs when static images are displayed for a long time, causing certain pixels to age unevenly and retain a faint image of the static content even when the display changes.

However, modern smartphones, including the Samsung Galaxy S20, have implemented measures to mitigate screen burn-in. They typically include features like screen savers, automatic screen dimming, and pixel shifting to help prevent long-term damage.

If you accidentally left your phone on the same screen for 10 hours, it's possible that temporary image retention may occur, but it should not result in permanent screen damage. To minimize the risk of burn-in, it's generally recommended to avoid leaving static images or high-contrast elements on the screen for prolonged periods. If you notice any faint image retention, you can typically resolve it by using your phone normally, displaying dynamic content, or letting the screen rest for a while.

It's worth noting that the specific behavior and susceptibility to burn-in can vary depending on the device's display technology, settings, and usage patterns. If you have concerns about burn-in or image retention, you can refer to your phone's user manual or contact the manufacturer for further guidance.

Certainly! Here are some additional points regarding leaving your phone on the same screen for an extended period:

1. Screen Aging: Over time, even without prolonged exposure to a static image, the pixels on a display may naturally age at different rates. This can result in slight variations in brightness or color reproduction across the screen. However, modern smartphone displays are designed to minimize these effects and offer improved longevity.
2. Screen Timeout: Most smartphones have a screen timeout setting that automatically turns off the display after a certain period of inactivity. This feature helps conserve battery power and reduces the risk of burn-in by preventing the same image from being displayed for an extended duration.
3. Display Technologies: Different smartphone models may utilize different display technologies. While OLED displays are more susceptible to burn-in, LCD displays are generally less prone to this issue. LCDs can experience temporary image retention, but it often disappears quickly and is less likely to become permanent.
4. Prevention Measures: To minimize the risk of burn-in or image retention, you can take proactive steps, such as reducing screen brightness, enabling auto-brightness, using screen protectors, and periodically changing your wallpaper or screen saver.
5. Pixel Refresh: Some smartphones have built-in mechanisms to refresh the display and help prevent burn-in. These features, such as pixel shifting or screen refresh cycles, subtly move the pixels to distribute wear evenly and reduce the chances of image retention.
6. Warranty Coverage: If you experience persistent burn-in or image retention issues on your smartphone's display, and it falls within the warranty period, you may be eligible for a repair or replacement. It's recommended to consult the manufacturer's warranty policy or contact customer support for assistance.

Remember that while leaving your phone on the same screen for 10 hours can pose a risk of image retention or burn-in, it's not a guaranteed outcome. Modern smartphone displays are designed with technologies and safeguards to minimize these issues. By using your device normally and following recommended usage practices, you can help maintain the longevity and performance of your phone's display."

According to Telus:

" TELUS Support

After eight seconds or once an emergency alert is acknowledged, the alert will no longer display on your home screen. Some smartphones allow you to save and ...".

Now this is useful - appreciate you digging up this information for everyone to read.

However, like I mentioned before - on the latest Galaxy S devices, when an alert is received, it wakes the screen and keeps it on for the entire duration of the owner's absence until battery is drained and phone shuts itself off. I know this because it has happened to me a handful of times over the years.

This is flawed OS behavior that Samsung must immediately correct to help preserve their users' hardware.

(And that notice from Telus does not apply to Galaxy S devices - but is likely accurate for most other phone manufacturers that allow their screens to go back to sleep shortly after receiving an alert.)

I've got a couple of devices that receive the Alerts, usually I have one of them with me, but I don't recall returning home and seeing the screen still showing an Alert on the phone left at home?

The Alerts are sent by the Canadian Carriers.. If your screen is staying on, I don't know if contacting your Carrier, using a new SIM or Resetting Network Settings would help?
