Harassment on Galaxy A11 Phone

[J Carver989899]

Help Android and Samsung Pros:

I have two Samsung A11 phones through Straighttalk and and a Samsung S5 that shouldn't have cell service. My cellular wireless signal is automatically connecting with incomming harassing people. (Its a criminal back door). Does anyone know how to shut down the antennas on the boot? I am a root on the S5 phone. It may be some sort of secret service mode being used for criminal purposes. Wifi and airplane mode have no effect. How do I cut these guys off? Erase all of their software.. it's a hidden connection.Thank you. J Carver

Put the phone in flight mode, and then restart/reboot the phone. It will boot in flight mode and not receive any signals via the antenna.

As the phone is rooted, definitely reflash the firmware from a known good source, either original factory Samsung, or an appropriate and trusted open source custom ROM, e.g. Lineage OS(If available for your devices). That will erase everything. Also don't use any existing accounts that may have been compromised, e.g. Google. Make new accounts, and keep them secure, use strong passwords, two-factor logins, etc. Stay off any social media, like Fakebook, Twitter, TikTok, etc.
