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?
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.
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
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). T
hat 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.
