Tronsmart TS7 (aka Glacier TS7) installs random apps without permission
I have a (4GB) Tronsmart TS7 (some times known as a Alps Glacier TS7). It's a Chinese MTK6589 based phone running Android 4.2 purchased from geekbuying.
For the most part the device is stock, there are next to no pre-installed apps apart from the usual, and the only additional apps I have installed are: Playstation, Steam, ColorNote, Shuttle+, Root Explorer DI Radio, Chrome & Gmail
The problem I have is that there are apps appearing on the device that I am not installing. So far it has been the same set of apps that appear:
- Mobo Market
- UC Browser
- TrustGo Security
- DU Battery Saver
- 337 Game Master
(there may be more)
These apps don't start appearing right after a factory reset, but start to arrive 1-2weeks later. They also seem to be packaged similarly; when I say packaged I mean opening them seems to prompt with the same menu & style (accept licence etc) before it gets to the main app. Also, after you open the app from the app drawer it then creates an icon on the desktop. Maybe opening it actually does the installing?
The apps themselves seem
to be legit.
I have factory reset the device (twice), and changed my Google password but they are still appearing. They don't show up in my Play store history so they must be coming from elsewhere.
My main concern is that if it is downloading things without my permission, what might it be uploading
? Not to mention wasting my 3g data etc.
So I have a few questions:
- Should I be (really) worried?
- Is there a way to monitor this? eg connect to a wifi hotspot and packet capture the network traffic? or maybe use a process monitor (the ones I've tried so far haven't shown anything) to see if there is some sort of script in the background?
- Can it be stopped?
Thanks in advance, I would be interested to know if anyone else has/had this problem?
