According to [the FCC](https://www.fcc.gov/consumers/guides/wireless-emergency-alerts-wea) (emphasis mine): > WEA alerts only cover critical emergency situations. Consumers can receive four types of alerts: > > - "National Alerts" issued by the President of the United States or the Administrator of FEMA; > - "Imminent Threat" alerts involving imminent threats to safety or life; > - "AMBER Alerts" about missing children; and > - "Public Safety Messages" conveying recommendations for saving lives and property. > > **Participating carriers may allow subscribers to block all but National Alerts.** The latest "National Alert" (formerly known as a "Presidential Alert") was conducted on October 4th at 2:20 Eastern Time and iPhone users [couldn't turn it off](https://apple.stackexchange.com/questions/464997/why-did-my-iphone-in-the-united-states-show-a-test-emergency-alert-and-play-a-si/464998#464998) due to the law above. Is there a way for users with an Android phone to turn off such alerts?

I want to test the emergency broadcast notifications (those for extreme weather and similar) to make absolutely sure that they work and everything is set up correctly. How can I do this? Google only tells me how to disable them, when test broadcast for the entire USA happened in the past or gives me an app that produces fake alerts that don't use the builtin system.

Germany is preparing to use **cell broadcast messages for emergency warnings** issued by the government. A first country-wide test is planned for December 8, 2022 as part of the Nationwide Alert Day 2022 . Many publications claim that reception of these cell broadcast messages will only work under **Android 11 or newer**: * Warnsystem Cell Broadcast: Deshalb erhalten alle Handynutzer JETZT eine SMS von ihrem Provider * Cell Broadcast: Kaum kompatible Smartphones – Generalprobe verschoben * This discussion on XDA Forums also mentions problems: CellBroadcast and Emergency Warnings on Android - is it a mess? However, as far as I understand, the underlying technical standard is about 20 years old, and Android has supported cell broadcast for ages (since at least Jelly Bean / V4.1, release 2012). **So why should there be a problem with Android versions before 11?**

I recently found this page of settings in on my phone under Cyanogenmod, I had never even heard of this system before. mobile broadcast settings (click to enlarge) Are there any examples of this system being used in the past?

I got the recently launched HTC Desire 500 (Android 4.1.2, Sense 5). Since then I am continuously getting cell broadcasting messages (4 every 2 minutes). And shockingly, there is no option to turn off the cell broadcast neither in message settings nor in Call settings. When I compared my HTC Desire X with Desire 500, I saw the option is there in Desire X but not in Desire 500. The call center people are helpless. The Customer care center people are saying its a defect in the phone's software, so we cant repair it. So by the time the software update comes, does anyone here has any solution. It is really irritating and its sad that HTC doesn't have the solution to such a trivial issue which is actually a headache.

Recently, I received an SMS that the State Emergency Service of Ukraine will test the new Cell Broadcast notification system, and that test notifications will come from September 7th. Why don't they come? All emergency alerts in notification settings are enabled, and airplane mode is disabled. SMS: > З 07.09.22 розпочнеться тестування нової системи інформування про надзвичайні ситуації. ДСНС надсилатиме тестові повідомлення зі звуковим сигналом на телефон.

I've looked at the wikipedia article and it is very informative. But my husband had a Verizon LG Lucid with Android 4.0.4. NO WHERE can I find a way to adjust the cell broadcasts! I have a Samsung Galaxy and there is a page to check what kind of emergencies to receive notifications. I can turn any/all of them off. What about the LUCID??

I came to realize that in rare occasions when using the Android phone, Cell service provider (Mobile Network provider) shows some popup advertisements. Regardless of the app, screen I was in it always mange to draw over the screen. Recently I manged to capture the screen when it does (Se attached image). As I checked all the app's permissions to "Display over other apps" there were nothing other than some phone manufacture related and accessibility related system apps. I find this as an security risk as cell provider can hijack my screen. Also I don't thing this is due to a malware/adware since all the ads are related to cell network and their packages. - My question is how Android eco system enables this kind of facility? - Which mechanism or the loopwhole Cell provider might be using? - Is there anyway to disable this? (other than clicking over unsubscribe link on ad) As you could see in the image, I was checking emails and ad got popped over Edit: - I do have a customer care/help app installed which provided by carrier. However I made sure it doesn't draw over apps. - Device is non-rooted, and never touched the bootloader, so might be locked. - Familiar with adb and fastboot. And adb lists the device with proper permission. However while running adb shell appops query-op --user 0 SYSTEM_ALERT_WINDOW allow | while read line; do echo -e "\nPackage: $line "; appops get $line SYSTEM_ALERT_WINDOW; done gives empty results. - Tried adb shell appops query-op --user 0 SYSTEM_ALERT_WINDOW allow also but empty output

I have been receiving about 50 flash sms a day, with my service provider name TIM RS 51, from the number 50. As I read here, it might be a issue with activating and deactivating cell broadcast on the phone. However, I could not find the path suggested for the deactivation (Setting/Call/Other Call Settings). The option does not exist on this path. Any help?

I searched lot on google but I didn't find any working solution to stop receving messages from "50" I tried these solution but didn't work for me - https://android.stackexchange.com/questions/54673/is-there-no-option-to-turn-off-cell-broadcasting-messages-in-htc-desire-500 Does anyone really have a proper solution (have experienced). Also please dont mark this question as duplicate.

I was looking at Bump_(application) , and I found it interesting that they use location data along with other metrics to figure out whether two phones are next to each other. Is it not possible to do a similar thing using bluetooth or a similar technology that doesn't send your location data to a remote server? I'm assuming the two phones in question have the same app.

I am abroad and get such notices about cell broadcast etc when in Baltics in Fig. 1. My SIM card settings are in Fig. (2-3). Fig. 1 Broadcast-notice visible often in Baltics, Fig. 2 Settings > SIM Cards > Sim Card 1, Fig. 3 Settings > SIM cards > Sim card 2 I googled the *[city] 14442* but could not find anything about it. Perhaps, it is some piece of information about radio channels but could not find about it. Some threads recommend to configure Call Settings (here thread *Turning off cell broadcast in HTC Desire 816*). To turn them off in OxygenOS, you can go to *Settings > More > Mobile Broadcast settings* > choose there appropriately. - Turn off *Amber* alerts.

Lately whenever a missile is fired upon us, I receive cell broadcast alert about it. In my area of living the city alarms are working loud anyway but the cell broadcast sound is extremely alerting and is over stressing my 3 years old kid. I looked in the menu (Settings -> More -> Cell broadcasts) but and I found I can make it sound for only 2 seconds (instead of four). I would like to keep the cell broadcast but change the tune. any ideas how can I do that? Screenshot (click image for larger variant)

I am receiving more than 100 notification alerts for cell broadcast on my Lenovo A7000 with Android Lollipop. I did not found any settings for cell broadcast. Can anyone please help me in disabling this to stop these alerts?

I know its possible to show all broadcast events/intents that are triggered in android. But I wanted to list all the broadcast events of a particular android app. My purpose is, I want to test a particular app for broadcast theft vulnerabilities. It may be possible to reverse engineer the app and analyse the code. But its too time consuming. Is there any other methods to do this? Is it possible with logcat? Can it be retrieved from the manifest file? Any input is appreciated.

Is it possible to know how many devises are in a certain area? I'm just trying to passively count the number of people in a room and I was hoping that my phone could recognize them by WiFi, Bluetooth, cell or some other frequency. I don't actually need to connect - just want to get a count.

this question is with regards to HTC Desire X dual Sim. I have this device and since the day I purchased this device I am suffering a lot with the CID massages, in a minute I am getting 10-15 messages, and I am not able to turn that off. So please suggest me how to turn the CID massages off.

The phone is a stock HTC One X. The settings menu does not include a checkbox to enable/disable CB messages. They just keep popping up. **Update**: Halfer already gave the link to the wikipedia article about CB, which should explain it in more detail than I ever can. What it means to me is that I get location information as I move around in town. The screenshot here shows the checkbox for this feature on what I believe is Gingerbread: **Update 2**: And this is the extremely boring message. This particular one just shows the carrier name, so it's even more useless and annoying than if it were showing location information: [](http://img51.imageshack.us/img51/5582/201206111740201.jpg)
