I love the S6's orginal icons. Was lucky to get the Edge model for dirt cheap due to a cracked screen on the bottom right hand side of the screen and burn in.
I also have a white S3, international model I guess,(GT-I9305 with Exynos 4412, 2GB of ram and LTE) still running on Android 4.1.2. For some reason it says it's software is up to date, It doesn't recognize my sim card either.
a note 4 still working? wow but especially on kitkat one is rare but on marshmallow these like to have EMMC failure so downgrade to lollipop to prevent the EMMC failure... this is coming from someone who revived 4 note 4's with bad emmc and had one die againg on marshmallow but now that every single one is on lollipop they have lived for a while now though one is on lineage os 18 and it runs ok
Interesting Tracfone used the S4's bootup sound on their S5 model. On Sprint's XAS firmware which is basically their global model they use the S4/ Note 3's bootup sound which drove me nuts so I rooted both my N910C and N910P and copied over the PowerOn.ogg from my N910C over to my N910P and replaced the PowerOn.ogg from the Note 3/S4 with the proper permissions using Root Explorer.
