I have been using this device for two weeks now, having extensively tested it, and I can share my conclusions:
It is a very fast device with exceptional build quality (given the materials), lightweight and sturdy. I chose the yellow color as the back is made of synthetic leather, so it does not slip from the hand and does not collect fingerprints on the back.
Plenty of space (512GB) for photos, videos, apps, games, offline music. The 12GB of memory is sufficient, but I also chose the option of expansion (using part of the internal +8GB because, why not?).
The screen has extremely vibrant colors (10-bit in normal use and 12-bit with HDR content) and is very bright, making it easy to use under the Greek summer sun.
The main camera takes very nice - to excellent - photos in good lighting conditions. The same goes for videos. The selfie camera is also very good but not at the same level. I haven't used the other two (ultra-wide & macro) but they are of lower quality. It has OIS/EIS, resulting in very stable videos even when recording on a moving boat. So, I consider the camera usage for social media and IM (e.g., WhatsApp, Viber) to be excellent! For "difficult" times, such as sunset and beyond, the main camera is simply decent.
(I attach samples as they came out)
Regarding the battery, I was not particularly satisfied with its use. However, it is important to note that I always have all receivers open (BT, WiFi, GPS), use two SIM cards (Vodafone & Cosmote in 5G), and use the phone extensively for calls, maps, music, photography, and Lightroom for on-the-spot editing. No issues during standby.
It heats up slightly during the above uses, but not to worrying levels, and certainly the season does not help, as the screen works with high (up to maximum) brightness.
Very fast charging (67W), so the battery is fully charged again in 25 - 35 minutes.
With a package that includes everything (charger, cable, case, integrated screen protection), 12/512 and a cost below 400 euros, it may be one of the most value-for-money options.
Update 12/06/24:
Today, in the heatwave, I used the device for many photos and continuous recording in 4K/30FPS/HDR. At the same time, the device was uploading to Google Photos via mobile connection (5G).
The device heated up to an annoying (but not worrying) degree, and the response decreased as the performance likely dropped for protection. At some point, I couldn't use the camera and had to interrupt the upload.
Certainly not a common scenario, but since it happened, I consider it important to update so that potential buyers have a more complete picture.
Update 22/06/24:
Today, completely unexpectedly, the biometric recognition feature (fingerprint) decided not to work. I opened, for example, a banking app and the bottom "window" no longer appeared, or I locked it and tapping on the screen to unlock it resulted in absolutely nothing.
It was resolved with a restart.
