User Reviews

Most reviews praise Block Unknown Callers for effectively blocking spam and unknown calls, no ads, and ease of use. However, recurring issues include blocking not functioning in the background, intermittent failures after updates, and requests for better dual-SIM control. A few users report that updates break blocking or require manual app interaction to function. Addressing background reliability, update stability, and SIM-specific controls would better meet user expectations.

Pros

Blocks spam/unknown calls effectively
Works as described and does what the description says
Ad-free (no ads)
Easy to use with a simple interface
Reduces telemarketing/spam calls for many users

Cons

Not blocking in the background consistently / intermittent blocking
Blocking stops after app updates or crashes
Some users need to manually open the app for it to block (unclear blocking activation)
Limited or unclear dual-SIM support / desire to choose which SIM is affected
Occasional reliability issues or bugs reported after updates

ABSOLUTELY FANTASTIC. All i did was install it, then open it and I just followed the onscreen prompts and allowed it all that it wanted and set it to 'block all calls NOT in my contacts list'. I will be telling as many people I can how good this is. It works ABSOLUTELY PERFECT on my Samsung Galaxy A26 5G. I set it to be the default phone app just like it asked for but I just use my Samsung phone app to make and receive calls as i did before and all calls NOT in my contacts blocked. Thanks guys.
