Using the above thread, it shows 8MP only in case of video mode. Select camera -> go to settings -> and it is back to 5.2MP.
UPDATE (from June, 2019):
What I found with front camera is
1. Groupfie mode has 8MP
2. Selfie mode has 5.2MP
3. Selfie mode picture automatically gets cropped
To conclude use groupfie mode to get great pics with your front camera.
The same thing shows in my front camera 5.2mp instead of 8mp. When i went into selfie i changed near view to far view and it shows 8mp now. But if its near view its still shows 5.2mp. Hopefuly it will be fixed in next update.
Hi. When you open camera for selfie theres two amall icons on bottom of screen. If you tap it it will change to far away. Its the zoom in one that uses 5.2pm. The other is 8mp.
