Thanks for providing the information to protect my whatsapp messages.
I only use Huawei phones/tablets and only some of the app lock apps work with Huawei’s phone manager, especially its “block apps from running in the background” feature.
The only App Lock apps working on Huawei I found so far are Smart App Lock by SpSoft and Privacy Knight by Taobao.
Here’s my experiences (especially with using Huawei’s App Lock alongside with an extra App Lock app):
Smart App Lock
Only works fine (on Huawei G8, Android 6.0.1, EMUI 4.0 3) as long as you do not(!) install the Helper app that’s supposed to prevent it from being force stopped and you allow it to run in the background with Huawei’s phone manager! If the helper app is installed you can force stop Smart App Lock and it wont restart after a reboot or through its internal restart schedule. But: Without the helper app you can even use it alongside Huawei’s own phone manager app lock for locking critical apps with two different PINs or with fingerprint plus PIN!
If you don’t allow the app to run in the background (Huawei G8, Android 6.0.1, EMUI 4.0.3), it sometimes works and sometimes it just starts up locked apps without asking for the code… Behaviour like that is dangerous for a security app. But at least it works fine once you allow it to run in the background – just lock Huawei’s phone manager that controls permissions to run in the background and you’re fine. Unfortunately you cannot use the Huawei phone manager’s app lock alongside Privacy Knight since they both “battle” for being on top for entering the PIN or using the fingerprint.
So: An extra App Lock app alongside with Huawei’s app lock only works with Smart App Lock from SpSoft (for me and so far). Using a second App Lock app you can enable basic security with quick fingerprint unlock via Huawei’s phone manager and add extra security to critical apps with a longer PIN via Smart App Lock. Snart App lock will always cover the “use fingerprint screen” but apps you only fingerprint locked with Huawei’s app lock, can still be unlocked just with a fingerprint. On the other hand – even if you enter Smart App Lock’s PIN when requested, the Huawei app lock fingerprint will still be required by those apps. This is like an undocumented stealth feature!
