Well after a lot of testing I can confirm Record audio is not working as it should. Problems are:
a) sometimes if you don't set Noise recognition recording is never done (I left it one for 154 hours)
b) recording is done ONLY when noise duration expires (if you set it 10 min recording is uploaded after 10 min, if you set it to 30 min it will be uploaded after 30 min)
c) if you set it to 5 min with 10 min noise you will get far shorter recording (sometimes even 12 seconds)
d) every recording made is not continuous, it has a lot of gaps. I played a track with person counting from 1 to 1000 ( in 2 sec intervals) and in recording you can hear him saying "1, 2, 5, 9, 10..."
e) someone would think it is phone issue BUT I tried it on HTC Sensation and HTC Desire C. Yesterday I replaced my HTC Desire C with Huawei Ascend Y300 completely brand new and same errors occur
All my phones are NOT rooted. Tests were done on 2 phones "out-of-the-box" with premium licences, updated to latest version available in that time, Android versions 4.0.3, 4.1.1.
Somehow paying for premium with non working features doesn't have a lot of sense
