Root Call SMS Manager Customer Insights

1. there is no other way to make it back to original start interface.I have just bought it because one of my friend told me it is very good and it has a fast reject function that lets the caller does not hear a ring but unfortunately it not in this version !!!! Please i want the old version that have the fast reject option and thanks in advanceE: temporary 5 until I get spare time to mess with the app.

2. The 'kill' mode doesn't kill the in-calls completely like a 'Fast-Reject' mode on MTK devices.I would have gave 5 stars but it does not block text messages from people not in contacts.

3. I have noticed that some features, such as 'kill' & 'fast reject' of blocking methods on devices running with Qualcomm Snapdragon chipset is not 'working' or 'is missing' as it should, and that as works on MTK devices.

4. So, I was trying to figure out if this app had a setting to reveal hidden phone numbers / caller ID, because I don't want to block all private numbers, just the ones that may be harassing.

5. Only four stars though because documentation is pretty much nonexistent but the developer is quick to help with any question you may have on how to set up the different options in the app settings.

6. However, I had a situation yesterday whereby someone called from a private number (I couldn't identify the caller) to harass (for want of a better word) & I didn't recognize their voice either.

7. Just wish there was proper documentation on what all the different options mean.My intention of rating with 1★ is only to get your (developer) attention on my review for this wonderful and helpful app.

8. I paid for the full version thinking that would unlock that function but no, there is no difference.Its blocking all calls on my second sim card which is data only.

9. Does this work without root to block/silence sms notifications or not? I see it has a no root option but I cannot find what the limitations are of this in non root.

10. I've been using the free version of this for awhile now & it works well.

11. Having a good manual would have been great!Excellent app and works perfectly on my 3A.
