This application needs updating immediately as possible as it showing the incorrect software update information for the next software update that will be delivered to my Samsung A35 5G
★★★★★Matthew Delong· Oct 6, 2025
Great app, worth 5 stars. Latest update shows correctly Android version on device 👍

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 app. It's such a shame, you're not receiving all the credit here, while others on Twitter, get to post pics of your application and completely forget that this project is licensed under GPL and not a single credit was ever issued to you. Stuff like that really kills development for many. I hope you get all the fame and attention for this app one day. Don't let others ruin and take credit for what you built sir. Have a nice day!

It isn't showing the recent firmware version and always showing NULL in firmware found option. Please update it accordingly.

Always get notification reminder for new test firmware. But after I open and check the test firmware, it always shows the same code with the latest official firmware. A54 XID CSC.

Samsung s25 ultra haves android 16, One Ui 8 We need a new update for Check Firm.
★☆☆☆☆Krona· Jul 9, 2025
Sometimes the app randomly asks me to update it and that the current version is not installed. But of course there is no new update released. This happened a lot, and it goes back to normal after a few hours.
