Ratings and reviews

It's good that it lets you know when new firmware is being tested, but it doesn't let you know when it's going to be released. According to this app, Samsung have been testing One UI 6.1 on the A25 5G for 3 months and there's still no indication when it will be released. I know that's not the fault of the app, but it's frustrating.

Amazing and useful app! I really find this app useful, especially for it telling me when i will receive the next update. But just a question. How can i exactly know when they will release the update. Often the builds of my devive (A505FN) have number 2 at the end, so it means they've rebuilt the firmware 2 times with a new OS but like 3 times in a row. But the last discovered edit on the firmware is 2020/03/17, so since then no firmware change. Is there an exact way to know when?

This app is great, I have never had a problem and I love that it is open source for everybody who is rated the app one star either does not know how to use it or they were experiencing a crash which has since been fixed. And should really reach this app. If you look at all the other reviews they are all five stars. -goofwear on xda
