Sorry if I'm bothering you but I'm really conflicted between this Xiaomi pad 5 and the Lenovo tab p11 pro, their the same price over here
I love the xiaomi but I'm scared of the software, do videos (YouTube in full screen, netflix, chrome) still play in the split screen (portrait) while using other apps?
Also what do you mean by broken?
Sorry, forgot to answer your question.
I'm not sure about the performance difference between to two tablets, but Lenovo tab p11 pro has a OLED screen, that's a big plus. Although Xiaomi's LCD is good enough for general content consumption, but it's not good enough for HDR movies. In my country the P11 pro was 30% more expensive then the Tab5, and although i would prefer an OLED screen, i was not willing to pay that much.
You can playback two videos in two different apps in portrait split screen. I've tested this with Youtube and Twitch. What you have to keep in mind, that portrait split screen is stuck in 50-50% app ratio. You have no option to change it to 33/66% which you can do in horizontal.
