I just Skyped with my mother (far away) because her Android tablet (Lenovo IdeaTab S6000, running on Android 4.2) showed a strange menu with Chinese characters, almost like a bootloader. My short troubleshoot history looks like this:
- When pressing the volume-keys, the displayed content changed, at one point the text contained "GPS", so I assumed it would be some kind of "hidden troubleshoot menu" for showing system information.
- A restart was possible after pressing and holding the standby-button, after restarting everything seemed untouched.
- Just to make sure, we changed her passwords.
- She did not visit any suspicious websites, nor did she install any apps recently.
With my little knowledge, so far I do not feel able to rule out an attack or a trojan app, from what I can see she could have activated the strange menu by accident. Via internet research I only found one individual with the same problem, but no solution at all.
What can I do to determine the cause? Should I contact the provider/manufacturer? Is it safe to assume that her data & accounts are not compromised?
I know it is little information, so please bare with me, I just want to prevent damage.
Thanks for any advice.
Lenovo IdeaTab showed strange chinese/asian-symbols-menu, gone after reboot, do what now?
