AIM 55" UHD Smart TV (CZ2155) + sound bar

AIM 55" UHD Smart TV (CZ2155) + sound bar. Shows video content adequately and sound is OK but stinks as a Smart device. The device is not certified by Google so no DSTV (or a host of other apps) available. Netflix is on it, but you cannot upgrade to the latest version. I could not detect the RAM size, but on start-up +50% are used already. Because of this, the device hangs sporadically and have to be reset. I removed all apps loaded by me from the limited play store. My home wifi tracks at +10Mbps on my phone but this device only runs up to 2.9Mbps. I got it for R3999 from PnP. I forgot the rule: "You get what you pay for!". Lucky I have a Chromecast.
