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
★★★★☆ Stephen Nohas · Dec 14, 2025
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. Lt now only seems to show new OS updates which are testing, not security updates.
★★★★★ 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!
★★★★★ 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.
★☆☆☆☆ Andrei Constantin · Jun 28, 2026
Doesn't do anything when starting, it loads and loads and loads nothing on oneui 8.5
★★☆☆☆ Ionut R · Feb 13, 2025
No longer crashes when trying to use info catcher. However, the info catcher is not functional. Date of the firmware is also wrong (it's the date of the previous firmware)
★☆☆☆☆ 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.
★★☆☆☆ 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.
★☆☆☆☆ 文KV · Oct 1, 2026
After upgraded to android 17, check firm no longer working. It keeps loading after launched the app. Please fix. Thanks
