To conclude, following points I have noted after using it vigorously for few days so that someone is clear in his choice.
1. Very very capable processor and 2GB ram are showing it power with very fast navigation and no lag at all.
2. No heating for me (used HDMI extender) till now and no restarting for me.
3. For me pic quality is excellent with rich color and depth with fine detailing overall. Dolby Vision is there hardware wise, but currently not there software wise, so anytime may be available depending on google and licensing, but not a deal breaker for me as I found HRD 10+ better, unless u really have a 10 bit tv panel.
4. Sound wise, no issues to me. If you use external device then also you would not regret.
5. Live tv channels shows are also can be accessed directly from recommendations, but two big ones Sony liv and Zee5 are missing as of now from recommendations. Right now, it shows recommendations from Mx player, Apple tv, Hotstar, Prime, and Netflix, but again, it is to be fixed from google tv side not from realme.
6. You can develop ur listing from anywhere through your google account from mobile, laptop or tv and u do not need to remember and u will not miss, so very handy feature as mostly we use google.
Overall very very good buy I must say and now more onus is on google tv to take it further as hardware wise I do not see any issue here. Now FTS should have only two versions, one is Full HD one at 2200 or so and other 4K max at around 4000, then only it is worth. Otherwise at 2999, this thing is a vey good buy.
