O GridLayout entra em colapso na exibição pequena
eu tenhoLinearLayout comTextView, GridLayout e outroTextView. Ele é exibido corretamente em muitos telefones e tablets modernos, mas falha totalmente em telas pequenas como o Nexus S. Veja as fotos a seguir.
Tentei diminuir o tamanho da fonte, remover o fundo de 9 patches e até remover todas as margens. Eu podia ver apenas digit7 quando havia algumas margens. Depois eu os minimizei e posso ver quatro linhas com o primeiro botão que é renderizado com o dobro do tamanho da tela. Eu não entendo o porquê, deve terwrap_content largura.
Tentei minimizar o código e reduzi-o paraGridLayout com uma linha e ainda não se ajusta à largura da tela.
O que está acontecendo lá?

O Nexus 5x tem os mesmos problemas quando a fonte tem 38sp ou mais. É interessante que o designer do Studio mostre o layout correto, mas o dispositivo / emulador mostra a exibição corrompida e o seguinte erro:
D/android.support.v7.widget.GridLayout: vertical constraints: y1-y0>=197, y2-y1>=197, y3-y2>=197, y4-y3>=197, y4-y0<=785 are inconsistent; permanently removing: y4-y0<=785.

Atualização 16 de fevereiro
Manjunath Prabhakar disse que o problema pode estar relacionado a pesos. Então, tentei remover todos os atributos de peso e o layout faz mais sentido agora. Eu ainda não o consertei. Eu consideraria reescrever o layout em LinearLayouts aninhados como um passo para trás, portanto, abro a recompensa para outras sugestões.
