[Android Software/Hacking General [Developers Only]] waqassikander:
I have been using galaxy devices after my iPhone got hacked and it was a relief since then but till now only. The threat i am going to put forth is very complicated yet true and it exists in both of my galaxy devices i.e Samsung Galaxy S8+ (Snapdragon) as well as Samsung Galaxy Note 8 (Snapdragon).

THE PROBLEM:

My both Samsung phones are remotely accessed by someone. Everything i do on screen is being monitored by someone as well as the camera and microphone are being controlled. I know this because my earlier phones(Apple iPhone 6 and VivoY91c) used to be hacked and the hacker would tell me everything i do on screen, every person i chat with, every site i visit, everything that i do on my phone was being monitored. And now same is the case with Samsung. Nothing is private. I even tried to install an app called "screensings" but it was also bypassed very soon.

THE SYMPTOMS:

Strangely, I do not have any symptoms like battery drain, ads, unknown apps or anything of that nature. My phone location changes to "Redkino, Russia" it seems to me by all aspects that I am in Russia. my weather, the ads on Youtube, the people nearby me in apps, friend suggestions on facebook and snapchat. It feels like this phone is physically in Russia. From weather to apps to everything. Even if i see things for sale of OLX it shows Russian items.

THE PROCESS:

As far as I noticed this happens through any app that runs on one device at a time i.e KIK , What's app, Snapchat, Say HI, etc NOT through apps like facebook or twitter or instagram that can run at more than a device at a time. The experts can relate later what it means may be at the end of reading this narrative. Every phone i change , my whats app number remains the same and as soon as i install whats app in new phone or SayHi or Snapchat ID. As soon as i activate my account within an hour or two my phone gets to Russia. As i searched the hacker attaches some trojan through these apps that can be used in device at a time and that trojan drops payloads. The payload gets root access and after that my phone is being monitored and controlled.

MY EFFORTS:

I started with a normal restart. Did not work. I factory reset my phone. It did not work. I flashed the firmware with new custom rom. Didn't work for me. I finally managed to extract the PIT file of my stock firmware and RE-PARTIONED and NAND ERASED my phone and then installed new firmware. IT WORKED. Which indicated that the malware had reached to system partition. (WHCIH IS WHY I AM MAKING THIS COMPLAINT) my phone was back to normal i used it for long like months and then one day again i had the same issue. So i did the same i re-partioned and NAND earsed my phone. But now it will NOT work any longer. I do not know where is the malware hiding itself now. ? Do i have to change the board of my phone to get rid of it or do i have to change my device? i even flashed verizon firmware on my sprint phone so that may be it will kill the malware but it also did not work. Soon after new firmware my phone is ok as long as it is not connceted to internet / WIFI as soon as its connected it gets to Russian like within 5-8 hrs (after firmware flashing). 5-10 mins after(After factory reset) . I have to change both of my devices for now. But i Hope and pray that Samsung fixes it soon. Something is getting into the read only system and then after its gotten there Samsung's owns security system is protecting it from deletion.

ATTACHMENTS:

My attachments show clearly that i am at KDA KOHAT PK and REDKINO RUSSIA at the same time which is not possible. I even get the location of Russia house where my samsung devices are being monitored or cloned. This is the only sign or symptom but the problem is there for sure as i the whoever the hacker is selling my info is after me and everything i do on my phone is reaching him as it is as if she is watching me right from behind my shoulder. Please look into the matter and find out where lies the vulnerability from where a malware can access phone through an app over wifi and hides in system partition that is immue to factroy reset and afterwards some place where its immue to even flasing firmware NAND erase and re-parition.
