Good compact phone

After several years on Sony Xperia, I'm back to ASUS.Good compact phone I've been looking for. Battery might be not the best for such a powerful device, but it holds for one day just fine.With 256G of storage don't really miss the lack of microSD.

No SD Card Slot. Would have been perfect S10e upgrade. 🤦

I almost bought this, but then realized it doesn't have an SD Card slot, which is ridiculous. 🤦 This would have been a perfect upgrade to my S10e. But alas.... Still no viable upgrade.... Phones are either too big, only come in 128GB, no headphone jack, or no SD Card slot. As I use this as my main computing device, I need to have my 1TB SD card in to manage video files for my YouTube Channel. 🤷
