So you’ll still get onscreen interruptions. Does not stem the flow of spam calls, and your screen is constantly receiving multiple notifications from the app per call. Phone doesn’t ring. That’s the only plus here. ### 1/5 — Robo Shield scams Spectrum Mobile users *2025-01-13, version 2.1.4* Fed up with robocalls and scam texts, I tried Robo Shield’s 7 day free trial. It worked fine with my I-phone and had no issues with my Spectrum mobile service. So, I bought the annual subscription less than a month ago and now the app will not work with Spectrum mobile and does not offer a way to correct this and there is no one to speak to to fix it. I’ve requested my subscription be paid back since I am getting no service and I’m not even a month into the year I paid for. Robo Shield is a scam and no one should use them. My subscription started Dec. 19.2024 and it stopped working in January 2025. ### 1/5 — No *2024-09-05* Doesn’t even block its own test call. Terrible ### 1/5 — Removing call forwarding *2024-08-20* Tried to remove it by using the Verizon options and I get nothing. Had to go through Verizon customer service to have it removed. **Developer response:** Hi Anonymous1k0, we are sorry to hear about the trouble you had with the app. To assist you better, please contact our support team at https://support.roboshield.com/hc/en-us/requests/new and include the code "300824" in your email so we can continue assisting you.

Not helpful. I’ve deleted and reloaded the app only to get the same thing. This needs to be fixed or I need a refund and I’ll go back to my other spam blocker.
