Sound is still a problem in this TV. It doesn't feel like 30W speakers. If you can manage to connect soundbar I think that should be fine.
Everytime power goes and comes back, I need to disable WiFi and enable again. Though its irritating, now I used to it. So no issues for me.
I never felt TV is slow dueo to low RAM. All the apps like Hotstar, Prime, Zee5, Youtube opens without any lagging issues. I also side loaded Kodi and using it as a media player.
When I purchased, I listed down all the issues and sent mail to Customer care. there were multiple follow ups but nothing happened so far.
Recently I got android 9 updated with July security patches.
I am not sure how to check the screen bleeding .. Let me know how to do it so I can tell you.
Overall I am fine with all the above stated issues considering the price of the TV. My only unsolved issue with this TV is surround sound. I tried all the combos like HDMI(ARC), optical etc.. but nothing worked. So I decided to use FireTV stick with Kodi for my setup to get 5.1 Audio.
The HDD is connected to router so it can be accessed to both TV and fire stick.
