I'm currently using two phones:
iPhone SE (released in 2016) --> personal phone
Google Pixel (also released in 2016) --> work phone
I'm looking at the Mi A3 because (a) I need a dual-SIM phone to replace these two phones above; and (b) I'm a fan of using stock Android. I've done lots of reading and video-watching on reviews on the A3 for the past week (including going through this exact forum page) and finally just now I was able to get me hands on one at a nearby Mi Store.
The below 3 things were observed:
- The 720p display is not as bad as I was expecting it to be. I opened this exact forum page in the A3 and scrolled a bit; texts are crisp enough for my liking actually. However, the icons on the phone (especially round ones) and the rounded edges on the 4 corners of the phone are noticeably jagged (a.k.a. not a smooth round shape). For me personally, it is not a deal-breaker and I can live with it.
- The colors on the display are incredibly rich and full (again, for my liking; I'm coming from two 3-year-old phones) and I actually quite enjoyed myself reading through news articles with photos on the A3. Guess that's Super AMOLED doing its thang.
- Opened this exact forum page on all 3 phones, and switching back and forth between my 2 phones and the A3 did not give me any sort of viewing experience upgrade/downgrade impressions. The obvious differences that I could see were the jagged round icons and the richer colors on the A3, and that's about it.
TDLR version --> if you're coming from really old phones (3 years old at least), the Mi A3 can be considered.
Another thing that you will love is fantastic battery life. The SOT is amazing.
