i got my old XR replaced on the same day via Machines (pass it in early morning, after lunch time collect). so far i feel its mixed bag depending on how many appointments they have on the day itself

otherwise there is one Dr iDevice in One Utama at basement level you can check out. they do on the spot if not busy (<15min). but i dont know if they replace the IP adhesives. previously i only replaced my ip6 battery back in 2015 and they finished it super fast, ip6 dont have IP rating back then
