On GSM Arena there are many reviews, and in each one there is a comparising chart of speaker's loudness. It could be 'Good', 'Poor', 'Average' or 'Excellent'. By you can't use this a criterium for finding a phone. Does anyone knows a web page where I can find phones by speaker's loudness?
My i9300 S3 is very quiet, in street traffic or in noisy areas I can't hear my phone. The vibration strength is poor. So I'm looking for louder phone, with better vibrator. But I can't google any page where I can compare speakers performance. Could you help me with this?
