I'm using a Xiaomi Redmi 3 device with latest MIUI 8 Global Dev Rom (Android 6 based with weekly updates). I'm only using Fingerprint Unlock and my device is not fully encrypted.
I'm wondering how hard it is for an attacker in case my phone is lost to access the internal memory. The external SDcard can be easily removed but is it easy to access the internal one?
I have not opened up the Xiaomi Bootloader, hence the theft could not simply flash another Rom to get access to the device. Also no USB Debugging / Developers options enabled. So in case he connects the device to a USB port; IMO there should be no way to get access to the internal memory, right? (a friend of mine broke the display of his iphone and not even the Applstore could help him get access to his DCIM folder to copy his non-backupped images; hence I hope this kind of security is also provided by the latest Android OS).
The only way I could currently think of would be to open up the device, somehow solder the memory ASIC to remove it from the platine and get access. As Im not talking about super safety-relevant data stored on my internal memory, this scenario will not come true for a random theft and is not in my focus asking this question.
Thanks in advance
