Is this safe to My SAMSUNG GALAXY S5 SM-G901F e-0.19-p-20211125148133-dev-kccat6.zip

BEcause some issue i read is it goes to bootloop?

Some heads up here

No, it is not. I tried to write a SMS and the phone crashed, but not only once but it rebooted about 3-5 times until it was “usable” again.

Despite that, the SMS application needs some rework ;- )
