I have a Miracast dongle attached to my television. Screen mirroring worked perfectly with Android 4.4.2. With the upgrade to 4.4.4 it stopped working. I hoped that the upgrade to Lollipop would solve the problem, but mirroring still does not work.
(Mirroring does work using the same dongle with my old Galaxy S3 as well as with my Lenovo tablet running 4.4.2)
Here is the sequence of events:
Clearly the problem is not with the "dongle" because (1) mirroring worked with my S5 before the 4.4.4 and 5.0 upgrades and (2) mirroring still works with both my S3 and my Lenovo tablet.
Any help would be appreciated.
Full reset did not fix the problem. Of course reset did not revert to previous android version. It appears that the problem is related to the "upgrade" from 4.4.2 to 4.4.4 and was not fixed in 5.0.
Thanks for the suggestion though.
I spent about an hour in an online chat with Samsung tech support.
After clearing the cache and trying safe mode...neither of which fixed the screen mirroring problem, he asked me to provide the Baseband Firmware version.
From my phone, the version is g900pvpu1boa6
The Samsung technician told me that this was not the correct version for the phone...the Samsung tech support site indicates that the correct version is g900pvpu1aoa6.
He indicated that the only solution would be for me to send the phone to Samsung (lose use of the phone for a couple of weeks) in order to have it re-flashed.
Numerous on-line sources, however, indicate that I do, indeed have the correct Sprint firmware version installed.
So...bottom line..Samsung tech support was unable to fix the problem, and in addition gave me what appears to be incorrect information regarding the firmware version on my phone.
Screen mirroring is not essential, but certainly would be nice, especially since it originally worked on my phone with KitKat 4.4.2, and stopped working with 4.4.4 and now with Lollipop 5.0
Just my $0.02
