It’s been a while now since I’ve observed the poor quality service of my phone, it low battery in short hours only and sometimes no signal on some area. I’ve heard the comments that maybe it’s because of my network provider or any other reasons. Or I guess I’ve dropped them a few times,(hehe) especially the voice quality, when I use the bluetooth of my car before it works properly, clear and loud but recently my friend says it’s very quiet. I don’t know what went wrong, if the car’s Bluetooth has a glitch or there is really something wrong really with my phone. Maybe next time instead of bluetooth I’ll use my akg headphones to compare the difference of the voice quality. If I test on headphone, I can distinguish which one doesn’t work properly.
I hope it will come back to normal soon.
