Why would it even be weird or anything? I only use Signal and its pretty much the same as whatsapp on the outside…just in blue. The only reason people dont use it is because “eVerYonE hAs WhAtsApP” and they dont bother. 20 useless crap apps but 2 messengers is too much
Note: if you somehow manage to uninstall system packages you can’t reinstall those (afaik). At least i ended up having to reset the phone twice while setting up and trying to change the default camera app. Not the worst on a new phone i guess.
