Hi all. Is there lag on my P6 or all of them have issue with low volume through 3.5mm jack? Before had plenty phone running my Dr. Dre Monster Studios and all of them had good vol level. Only my current P6 lacks output power. Have tried various headphones (Sennheisers, Samsung galaxy s3 oem, Huawei P6 oem, iPhone 5 oem, and Monster Studios) but still cant reach same volume level. Have tried couple Google Play apps to increase volume, but they doesn't to job they suppose to do..
