Very nice, elaborate set up. It shouldn't be normal behavior to have to reset your Galaxy phone as you walk from one room to another but that does depend on how things are set up. If you have each access point working with a unique SSID there could be a issues for your phone to switch from one to the other if those four rooms are in close enough proximity to each other there's a lot of overlap between each room to another. Also if you have each doing it's own routing functions (DHCP and DNS) for each SSID that also makes for the same problematic issue for your phone to switch from one to the next. A lot of this is also conditional to the spacing of each of those four rooms. And one last thing is if you have the wireless routers in rooms 2, 3, and 4 connected to your TP switch via Ethernet cables, or if you have one or more of them connected via WiFi (bridge mode).
Ideally it will work out better if the three wireless routers are connected to your TP switch by Ethernet cables, all three routers having all routing functions disabled so they're all working just as wireless access points with your Arris cable modem/router being the sole, master gateway of your entire home LAN. (All three wireless routers need to have routing turned off in their configuration menus, and only use the LAN ports for the Ethernet cables, no WAN port.) All four (Arris, D-Link, Tenda, Cisco) need to have coordinated channels set for the WiFi to eliminate conflicts and seamless changeover from room to room as you walk around. (with channels 1, 6, and 11 if you're just in 2.4 Ghz but I'm assuming with your set up you have a 2.4 and 5 Ghz in use???). The end result should be your home LAN is using a single SSID (with same password), with any devices using your WiFi being able to get uninterrupted connectivity as you walk around from room to room, the only change being the channel switch over going on in the background. Any changes in things like IP address should NOT happen as your Arris is your sole gateway.
With four wireless routers in use, have you thought about using a mesh network instead? Tack on Orbi or Eero to your Arris will give you an easier network to set up if at some point you want to upgrade your routers.
