Hi all,
I have encountered the following when deploying my game to my tablet (Cube U27GT-s, android 4.4.2):
The graphics quality is low, it is low res, some buttons are not working (they are there but nothing happens when I click them). The sceen is zoomed in, even if my tablet’s res is 1280X700, (16:10). I did test that res out on my widgets but to no avail. I did set the scalability to epic and I did set my device profile’s scale to 1.0 (all the low, mid and high quality is 1.0).
I did try putting a default device profiles .ini file in my config, but to no avail.
I seek technical advice, as my game is ready, I just have to make it run properly on my tablet.
i don’t know much about quality settings but here as @psychogony mentioned
">
(not sure what he said but it was something regarding textures)
you may like to take a look at this , quality of umg (this one has many links)
and as for the buttons ,
are you sure they are using on press event?
have you tried z order? maybe the widgets get under each other and thus can’t be pressed?
this is more of an deployment issue so STAFFS or someone who have tried this before should have more knowledge here.
Thanks again for the help 
I’m sending multiple emails towards epic games as well, and I have just upgraded UE to 4.12.5 and reinstalled my codeworks sdk. restarting now, see what happens.
by the way now the game won’t even package, I get errors. lovely, I spent 3 weeks, 12-13 hours a day developing this
Now, as for the textures (without reading them). My formats are PNG. is that suitable? Checking the buttons’ Z-order in the meantime, I might have missed something.
PNG is supported,there size should be in power of 2 and maybe this would be helpful
are your textures saved via Photoshop? if yes check my this answer explaining about alpha from Photoshop
i would recommend you go for steam as your modeling and texturing skills are good but mobiles kill the graphic capabilities of game (for ue4) although marketing and distributing gets easy for androids/ios. i don’t know how steam things work , but i was able to get the steam overlay somehow , so go for steam (probably for your next game).
I was using Gimp as the project has no budget, I used only open source and/or free software (blender, gimp).
I would like to go for facebook (html5) and google play, as well as amazon apps for this project, well if somehow I can fix it.
The textures are not the power of two, I cropped them so they best fit the image within. I have no issues with the alphas, and I did set my textures’ compression and whatnot to UI.
are your ALL textures showing in game? if they are not in power of 2 they WON"T show up in game (actually won’t package, not sure why we have to do this) it is explained here
they can have these sizes
everything shows up. And now, after I reinstalled the code works it did package. got 188 MB of size out of this weak project btw 
I do understand what a power of two is, come one I have just seen others using Unity and cropping the UI elements to the images’ sizes. I’m using UI images only, not actual textures, like albedo, glossy, metalness etc.
additional info: as I think UE does not support UDIM UVs atm, only the 1 to 1 space texures for meshes will appear. This means yes, the power of two. usually .5K or 1K for mobile. But this does not appy to UI elements, or at least in my case it doesn’t everything shows up, yes.
okay so does that project work? properly? the 188 MB one?
cheking now. btw how do I magic it to the device? use the installer and select my tablet?
edit: I did install it using the .apk file. Now, when I want to start it, it says “no .obb file and no key from store to download. get a key”.
It DOES have an obb file, I have just copied it. It was in the build folder.
you don’t copy it run the .bat file.
with device attached via usb
thanks fot the heads up, doint that right now.
I did it, and it said that “Errors occurred, install failed”.
I did have my device in development/debug mode.
by the way my computer does recognise the tablet as adb device. It does have an SD card.
It said it failed to copy the .obb file as it does not exist.
But it does, I have it right there.
so lets go step by step
1. you have android sdk for your android version installed
2.you have device showing in ADB devices
3.you have it properly connected(just to make sure)
4.try changing connection modes to CAMERA or MEDIA (from device)
5.check on other device if you have.
made sure of those. now trying on my mother’s tablet
fail, lack of storage -.- i will have to make the magic happen on mine
