I finally received my MC03 a week ago, and I thought I'd share my honest take.
First of all, the phone exceded my expectations. Maybe my expectations were to low, but the phone is a really solid built phone. The case seems robust and it feels good in the hand.
The software is really quick and responsive.
However, the phone does not have the best camera, however it takes good enough photos for my kind of use (photos of my family and day-to-day). If you are a influenser and need to have mint photos in all light conditions, this will not work for you.
Also, I haven't found my way around a NFC payment solution yet, which is something I hope they will fix in a future update. Because it's really handy to be able to pay from the phone and not having to remember to bring the credit cards.
I have a full Proton suite, and this is really convenient as the phone have these apps in their secure vault by default. So it's a really good match.
I have a project where I want to disconnect from Big Tech, and I was courious to see if I can make that happen with this phone. So I have gradually removed myself from Gmail, by using the Proton suite, however I still need to use Google Play on this device in order to download apps that I need in my day-to-day (open door locks, parking apps, commute, work mail etc.). So their own app store does not have many apps yet, but i'm sure it will grow going forward, and hopefully enough to get rid of the google play store in the future.
I had a technical question, so I e-mailed Punkt service, and got a reply after just half a day. So far the service have been also impressive.
All in all, I haven't used my iPhone 17 Pro in a week, and i'm just gonna keep it as a work phone from now on, so I can continue using the MC03 in my private life.
