T Mobile should issue refunds for the Revvl 5G

its how the manufacturer set it up..or lack of setting it up..as it was pointed out above..carriers have zero to do with how the device itself handles background workings or how it handles apps themselves..thats all on the manufacturer..the carriers only deal with your signal to and from the device.

figure Google kicks out their updates to the manufacturers..the manufacturers then make them work with their devices and then eventually use that same update and add in whatever the carriers need/request.. Revvl for whatever reason made their controls for anything running int the background WAY to aggressive..if it were a issue with Google or TMO then it would be happening to more than just that specific device line..might even check out XDA and see if they have some kind of work around..
