Hello house and fellow nairalanders, plz I hope I can get assisted with my problem here. A jealous and malicious brother with whom we share same house with, does criminally hack my android phone, thereby assessing my whatsapp and even browser history. I notice he is able to do this evil activities when we are in d same environment and unable to do it as distance increases esp when we are not home at the same time. Fellow great ppl, how can I effectively block him or what app do I need to use to cut him off. Thanks in advance.

Hes probably using a RAT(remote access trojan),I'd say you should wipe your phone cause the ways he might have been able to exploit your device is by him sending a file to your phone. And after you must have cleared your phone be careful when giving your phone to people to send things even on xender he could send the "payload" to you,Another case would be if yall are sharing same LAN(wifi) but I doubt that,there are many loopholes hackers can use sha. I learnt somethings about hacking for awhile before I went into forex so as to get enough funds to fund my hacking career(your neighbor is prolly a rookie)

d best is for ppl not to spend much time on these social media . All those end to end encryption are nothing but scam
