Sony - Never buy
Based on my experience with Sony Mobile and Sony Bluetooth I am never going to buy their hardware again. Its buggy and unstable. I am not surprised to read about this reaction about when bugs are discovered. At best, Sony Mobile fixed a bug that resulted in a crash when the Wi-Fi interface was in Icelandic on Android 8 on Sony Xperia XZ Premium. Other bugs (unstable Wi-Fi) were not fixed.
