    EPICS plans to support - sub 100$ tablets

    I picked up a sub 100$ tablet (http://hisense-usa.com/tablets/sero7lt) as well as I have a sub 50$ tablet being shipped (http://www.dx.com/p/a13-7-capacitive...6#.VSEkoJMplwh)

    Sadly though - My 100~ tablet wont run unreal 4 (tappy chicken from epics store), it will run unreal 3 (the epic citadel) as well as every unity game I've tried.

    All unreal 4 games (from store or deployed by me from editor) just sit at a black screen for a moment then quit to the dashboard

    I know I could just buy a supported 200$ tablet - but that goes against my strategy and might as well switch this project to unity. Is it in epics plans to support these low end devices? I can see this being a huge problem if they don't as many people will buy these for their kids

    Tappy Chicken came from Epics store on the play store and DOES NOT WORK engine shows a black screen - I submitted debug reports and am not able to find logs, the google play icon shows briefly but its a black screen then crash to desktop

    How well does Flappy Birds work on these devices.

    Typically, sub $100 tablets are such due to being woefully underpowered, even for their own UI, let alone a demanding game engine like UE4.

      i think this a big issue that epic chose to ignore and it could well bite them as far as mobile developers go.
      the key to mobile games is having it run on a decent proportion of devices, its no good if your game will only run on literally 5 or 6 devices in the world.
      yes sub $100 are underpowered but they are common, other engines seem to run on them just fine. out of the 5 (varied and fairly recent) android devices in my house only 1 of them runs ue4, even then its at a low framerate.
      ue4 has by far the best set of tools but its performance is just dreadful. if you plan on releasing a mobile game sometime in the next year or 2 the is no other choice but to use another engine.

        Did you try running the official versions that is shipped by epic https://play.google.com/store/apps/d...yChicken&hl=en . It may come down to something in your ue4 install being a little messed up.


        As far as low end / weird /cheap hardware.

        Much of it comes down to vendor/hardware used (were drivers the most recent with that kernel), the ROM used (heavily modified ROM, or AOSP rom). Settings become important for many of these devices (and what the GPU's support). Its not as "easy" to get them running out of the box with amazing performance but its reasonable. Unfortunately many of the uber cheap chinese tablets (which i have one), in the past, often used really weird chipsets, with half working drivers and features, and heavily modified/broken android roms. The GOOD news, if you get any of the newer ones (4.2+, especially the 4.4) many of them have more respected, tested, feature complete chipsets (Allwinner / mediatek, has largely taken over the cheap sector and has pretty good chip/driver support). Its becoming less, and less frustrating.

        I need to re-do this since last time i tried it on these "odd ball" devices was ~4.3 . https://forums.unrealengine.com/show...e-for-yourself

        I have 6 android devices (from 4.1 to 5.1),2 nexus devices, 2 samsung devices, onda tablet, Neptune pine, all of them run UE4. The performance will rarely exceed unity, but if you take into account the hardware's ability (and using UE4) it actually doesn't do half bad . Most importantly they all work (for me).

        The newer ~50$ Chinese tablets are surprisingly competent with Allwinner A33 chip.

          @ KRushin
          are you doing anything special to get ue4 running on those devices?
          for me, actually i have 6 devices here
          galaxy s - the oldest device i have, does not run ue4, struggles with heavier unity games but runs them (fastest custom rom and kernel i could find)
          unbranded chinese phone - runs all unity games without issue, does not run ue4
          hannspree tablet - runs all unity games without issue, does not run ue4 (fastest custom rom and kernel i could find)
          allwinner tablet - runs all unity games without issue, does not run ue4
          galaxy s3 mini - runs all unity games without issue, ue4 runs at ~6fps at best (fastest custom rom and kernel i could find)
          nexus 7- runs all unity games without issue, ue4 runs at ~30fps at best

          *note none of them run ue4 with mobile hdr enabled, nexus 7 does kind of but at ~1 fps

            I updated the title - yes tappy chicken DOES NOT WORK coming directly from EPICS store page

            https://play.google.com/store/apps/d...yChicken&hl=en

            You can see others have this issue in the reviews

            "Doesn't start. Just black screen. Pressed icon to start. Only get black screen. Epic disappointment. "
            "When i go on it the skren gows black then it gows on to my home page "

            Epic Citadel (unreal 3) from EPICS store runs *GREAT* on this device, so this makes me think its a bug in unreal 4

              BPANDREW,

              Who is the manufacturer and what is the model number? Do you know which GPU it has and the Android version installed?

                  BPANDREW,

                  Looking at the specs, this should have a Mali-400 GPU. Tappy Chicken should work on this device. The best way to try to troubleshoot this would be to have you try packaging a development build of Tappy Chicken with 4.7.4 and capture a logcat from the device to see how far it is getting.

                  You can run 'adb logcat -s UE4' to capture only the UE4 log messages.

                      I was using this logging technique to debug another unrelated issue that I fixed - I noticed the next logging entry after - EGL_KHR_get_all_proc_addresses is FOnlineSubsystemAndroid::Init - maybe this blackscreen issue is related to that?
