Comments on CheckFirm for Android

★★★★★ Donovan Gregg · Apr 8, 2026

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

★★★★★ Pankaj Chauhan · Jul 16, 2024

VERY GREAT APP. ACCURATE INFORMATION MILTI HAI TESTING FIRMWARE KI. MAI CHECKFIRM APP KE DEVELOPER SE REQUEST KRTA HU. IS BAAR NEW UPDATE MEI NEW USER INTERFACE LEKE AAYE.

★★★★★ G Prz · Jul 10, 2025

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!

★★★★☆ stephen nohas · Jun 2, 2024

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.

★★★★★ Matthew Delong · Oct 6, 2025

Great app, worth 5 stars. Latest update shows correctly Android version on device 👍

★★☆☆☆ Aditya Aryan · Apr 15, 2026

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

★☆☆☆☆ Fahmi Nagi · Oct 6, 2025

Samsung s25 ultra haves android 16, One Ui 8 We need a new update for Check Firm.

★★☆☆☆ Falah Fenderian · May 18, 2024

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.

★☆☆☆☆ 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.
