Search lock screen on play store rather than deleting apk of lock screen.

[Completed] Hi~ I just want to know if it is free if I have my phone fix in every Samsung Center?

I'm using Samsung S5 . Yesterday it says that to upgrade my system but then after upgrading it, it goes restarting and later on it won't turn on. The logo will appear then turn off again. It's just that over and ever again. I tried removing the battery for hours but still the same.

Hello, and welcome to XDA Assist! Sorry to hear about your S5. You would probably need to phone them and find out as we don't have that kind of information. But you may want to register and try posting your question here: Galaxy S 5 Q&A, Help & Troubleshooting. Someone may have the answer for you.
Good luck!

Hello, and welcome to XDA Assist! The best thing to do would be to register and ask in the thread of the rom that you installed. Alternatively, you can post in the help forum: Galaxy S 5 Q&A, Help & Troubleshooting.
