[Android] Samsung Tab 3 & 4
Hi Greg,

there is an issue with Samsung Tab 3 and 4 as we currently found out launching our game to the public.
I've come across one error log file which I have attached.
It looks similar to the shader problem that occured (and seems to have been fixed) a while ago.

Error accessing ShaderTech "Draw2DTex" in Shader "Main".
Error linking vertex+pixel shader in technique "Draw2DTex" of shader "Main"

Log file attached.

RE: [Android] Samsung Tab 3 & 4
Unfortunately I don't own any of these devices and don't see anything wrong with the shader.
"Error linking vertex+pixel shader" is an indication that OpenGL fails to stitch the Vertex and Pixel shaders together.
This could be a reason for varyings being defined differently for VS and PS.
That's why I've introduced BP macro to autodetect best precision available on both VS and PS, to make sure both varyings have same precision, however it seems it's not enough for these devices.

I think this device is still used fairly often because of its price.
How much would a used device cost you? I'd be willing to support you there so you can make the shaders work with it.

Thank you, I'll look around the average price and will see what's there.

RE: [Android] Samsung Tab 3 & 4
Hello,

I'm checking the prices, however there are several models of Galaxy Tab 3:
7.0 Lite - http://www.gsmarena.com/samsung_galaxy_t...0-5969.php
7.0 - http://www.gsmarena.com/samsung_galaxy_t...0-5422.php
8.0 - http://www.gsmarena.com/samsung_galaxy_t...0-5456.php
10.1 - http://www.gsmarena.com/samsung_galaxy_t...0-5491.php

Each of these models has a different GPU, so it's possible that it has different OpenGL GPU driver, so I would need to know first which model does not work, so I could get the same one.

The same story is with Tab 4:
7.0 - http://www.gsmarena.com/samsung_galaxy_t...0-6251.php
8.0 - http://www.gsmarena.com/samsung_galaxy_t...0-6249.php
10.1 - http://www.gsmarena.com/samsung_galaxy_t...1-6247.php
10.1 (2015) - http://www.gsmarena.com/samsung_galaxy_t...)-6980.php

Hello,

I've added this to the store: http://www.esenthel.com/?id=store&cat=4
Once the purchase is made I'll order the device and then start working on the compatibility issue.

Before making the purchase however, please consider if it's worth the money and effort, as I'm not sure if Galaxy Tab 3 is an important device for now and the future.
It's 2 generations behind the latest model (Galaxy Tab 4 and Galaxy Tab S).

For example some months ago I've spent time on making the engine work on Galaxy Tab 2, and now I'm not sure if there's anyone still using this sort of device. I'm wondering if Tab 3 soon will become extinct too.

Apple iPad is still the king.

Couldn't find some better tablet chart sales, so this is tablet usage from US only:

Just to shed some more detail to this conversation, the Chitika report shows the usage reports, meaning that of all the tablet users, iPad users are spending the most time, at least over the web and internet using an Apple Tablet (iPad).

As far as sales ratings and ownership numbers of tablets go, Apple has been slowly but surely declining:
http://www.computerworld.com/article/260...ction.html

From a world-wide report, Android tablets sales far outweigh Apple tablets:
http://www.idc.com/getdoc.jsp?containerId=prUS25267314

And the Android usage growth is expected to grow a consistent % year over year.

But I think what matters more for us game devs is what platform has more spending users and also what region of the world has users that spends the most. For example, Apple users spend the most in North America and xyz countries have the highest spenders under Android.

RE: [Android] Samsung Tab 3 & 4
With the low users that we have we almost see the same amount of sales on Android and iOS, with even less users on Android.

Ok, here's the thing. I'm not willing to spend 350 for this. You can get a used model for less than 80€ on ebay, not even an auction. That's totally enough for testing.
Also, it's not only Tab3, I got reports of Tab4 as well. Still fetching the exact model of it.

I think it should be in your interest to fix this, as Samsung is a huge manufacturer of Android devices and it's just plain bad to not support that famous line of devices.

I'll add a workaround for max vertex attributes for next release, let's see if that will help.
