I think you first have to find out if there is really no encryption feature in your ROM. From the Huawei support I would expect that they can tell you if this is actually the case! Maybe someone in the forum has also some more experience with the absence of the encryption feature in manufacturer-ROMs?
Some more points that come into my mind:
- Do you even see the option to activate encryption in the settings?
- You have to choose PIN or password as unlocking method for your phone. Otherwise encryption can't be enabled.
- Did you root your phone? Can you try to activate encryption via terminal or ADB? Here is the command you have to execute as root:
/system/bin/vdc cryptfs enablecrypto inplace YOURPASSWORD
thank you for all your work!
Yep, I had some phone calls with Huawei and those option really does not exist.
As I have a connection to exchange already, I use a screen lock with PIN.
I checked Storage and Security screen several times to really be sure not overseeing anything
Regarding ADB I only have a Windows 8 Client from my employer where USB connection does not really work with ADB-drivers.
Can I run
a) that command in something like a dry-run to clearify if this option exists without really encrypting
b) that command from root terminal directly on my phone?
BTW: Yep, it's rooted.
Attached have a look at the mail from Huawei:
[...] Die Telefonverschlüsselung ist aktuell leider nicht in die Software des Huawei Ascend G750 implementiert. Natürlich gehen wir davon aus, dass diese in Kürze durch ein Performance Update nachgereicht wird. [...]
[...]Sadly the mobile-phone-encryption currently is not implemented within G750 software. Of course we expect to have a ???Performance Update??? delivered to fix that issue
