Same problem here. Newest software version. Since almost two years Pik TV is available on the media box. Actually not really because it's still not working the way I expect it to work. Needs some user action like reset or unplugging at least every second day, goes back into sleep mode after about 90 minutes into a new movie when watching Life TV, etc . Unfortunately I do not know where the real problem is. Being it providing inferior hardware as some people state or being it developers just simply unable to get a software package running without the most basic errors.
I'm using the box connected through cable, wireless off, static IP and I have no other apps loaded. The pre-installed YouTube app works flawless and so does my ROKU on the same subnet, so I'm leaning towards software that is not capable to handle the task. A company like TELUS should have access to people who can handle a job like error free streaming on an Android TV box.
Just to be sure, by "shutdown and reboots", you mean the full box reboot including seeing the 2 red LEDs at the front of the box and the "android" boot animation, right? Not just the Pik TV app restarting (the animation looks like the boot animation, so it may look like a reboot).
Full reboots are usually caused by hw things like power supply and overheating. Android usually takes care of killing misbehaving applications so they don't take down the system. I have been using the box for 2+ years and seen many issues, but sudden full reboot is not on my list, but my usage patterns may be different than yours. If you find any sequence that helps reproducing, I can give it a try on my box.
No, it's not a full hardware reboot/restart. Since YouTube works fine I tend to blame the Pik TV software or the feeding channel. 95% of the time I'm watching Knowledge so I don't have to mute the annoying ads others are trying to feed me with.
Error 1: When I start watching Live TV at 7:00PM and not changing channels, then at 10:20PM more or less the screen goes black. Without interaction it changes to the Android background. If I press Ok on the remote Live TV continues. This error appears regularly if one sequence is longer than an hour, saying it starts at 8:00PM and is supposed to run till 10:45PM or so (Fridays, Saturdays and Sundays on K). It also happens randomly.
Error 2: I'm watching Live TV and suddenly an error message appears in the middle of the screen saying something like the application has to restart, reload or whatever. Sorry can't remember precisely. I get a choice of Ok or Cancel. Hitting either or not doing anything brings the app back on track after a while. From the looks I would say it is from the system. This happens on different Live TV channels.
Error 3: Channel surfing - After some channel changes, carefully letting the system settle each time after the change, the app locks up. When I'm lucky I can go Home. Settings, About, Restart and the app restarts. If I'm not so lucky and the system is completely frozen then the only option is a power cycle.
I'm on PureFibre 25 with 30 Mbs download, wireless completely off, static IP and no others using the connection. The box is fully updated to the newest version.
