Same issue here

4.25 apk runs fine, 4.26.1 apk crash

Hi, so I built the apk 4.25, runs great. I switch to build with 4.26.1, nothing change except engine version, the apk works on some devices, but on Amazon Fire HD (OpenGLES3.1), I get a crash after splash screen. The log cat shows OpenGLES has error 03-04 02:17:29.678 9500-9541/com.xxx.xxx D/UE4: [2021.03.03-18.17.29:678] 0]LogCore: Display: AppLifetime: Application has entered foreground 03-04 02:17:29.679 9500-9541/com.xxx.xxx D/UE4: [2021.03.03-18.17.29:678] 0]LogCore: Display: AppLifetime…

I guess this is because

if (IsES32Usable())
	{
		glTexBufferEXT = (PFNGLTEXBUFFEREXTPROC)((void*)eglGetProcAddress("glTexBuffer"));
		glTexBufferRangeEXT = (PFNGLTEXBUFFERRANGEEXTPROC)((void*)eglGetProcAddress("glTexBufferRange"));
		glCopyImageSubDataEXT = (PFNGLCOPYIMAGESUBDATAEXTPROC)((void*)eglGetProcAddress("glCopyImageSubData"));
		glEnableiEXT = (PFNGLENABLEIEXTPROC)((void*)eglGetProcAddress("glEnablei"));
		glDisableiEXT = (PFNGLDISABLEIEXTPROC)((void*)eglGetProcAddress("glDisablei"));
		glBlendEquationiEXT = (PFNGLBLENDEQUATIONIEXTPROC)((void*)eglGetProcAddress("glBlendEquationi"));
		glBlendEquationSeparateiEXT = (PFNGLBLENDEQUATIONSEPARATEIEXTPROC)((void*)eglGetProcAddress("glBlendEquationSeparatei"));
		glBlendFunciEXT = (PFNGLBLENDFUNCIEXTPROC)((void*)eglGetProcAddress("glBlendFunci"));
		glBlendFuncSeparateiEXT = (PFNGLBLENDFUNCSEPARATEIEXTPROC)((void*)eglGetProcAddress("glBlendFuncSeparatei"));
		glColorMaskiEXT = (PFNGLCOLORMASKIEXTPROC)((void*)eglGetProcAddress("glColorMaski"));
	}
	
	if (!glEnableiEXT && ExtensionsString.Contains(TEXT("GL_EXT_draw_buffers_indexed")))
	{
		// GL_EXT_draw_buffers_indexed
		glEnableiEXT = (PFNGLENABLEIEXTPROC)((void*)eglGetProcAddress("glEnableiEXT"));
		glDisableiEXT = (PFNGLDISABLEIEXTPROC)((void*)eglGetProcAddress("glDisableiEXT"));
		glBlendEquationiEXT = (PFNGLBLENDEQUATIONIEXTPROC)((void*)eglGetProcAddress("glBlendEquationiEXT"));
		glBlendEquationSeparateiEXT = (PFNGLBLENDEQUATIONSEPARATEIEXTPROC)((void*)eglGetProcAddress("glBlendEquationSeparateiEXT"));
		glBlendFunciEXT = (PFNGLBLENDFUNCIEXTPROC)((void*)eglGetProcAddress("glBlendFunciEXT"));
		glBlendFuncSeparateiEXT = (PFNGLBLENDFUNCSEPARATEIEXTPROC)((void*)eglGetProcAddress("glBlendFuncSeparateiEXT"));
		glColorMaskiEXT = (PFNGLCOLORMASKIEXTPROC)((void*)eglGetProcAddress("glColorMaskiEXT"));
	}
	bSupportsDrawBuffersBlend = (glEnableiEXT != nullptr);

then

static FORCEINLINE void ColorMaskIndexed(GLuint Index, GLboolean Red, GLboolean Green, GLboolean Blue, GLboolean Alpha)
	{
		if (bSupportsDrawBuffersBlend)
		{
			// ES 3.2 or extension
			glColorMaskiEXT(Index, Red, Green, Blue, Alpha);
		}
		else
		{
			check(Index == 0);
			glColorMask(Red, Green, Blue, Alpha);
		}
	}
