Recently I came up with unfortunate situation with my new Samsung Galaxy S5 4G LTE SM-G900 phone which was purchase from Kogan Nov 2014. I have bought Backup replacement battery from ebay seller called dodygroup (http://www.ebay.com.au/itm/Backup-replacement-battery-for-Sa… )and I had no issues with battery until I found some bulge on side of the glass one morning. Basically I thought this was screen protector and suddenly when I close the s-view cover I was shocked when I see white lines appearing on my screen like old TV and within few seconds screen turn black and died. Finally noticed that LCD digitizer was damaged due to slight pressure on bulge. Previous night I watched you-tube videos 1-2 hours ,turn on night light app and plugs into charger for overnight charging.
I was given my mobile for Technical assessment for Kogan and they have informed its not covered under warranty and discovered following during assessment, technicians had tested the battery for overheating (which could cause such a bulge), they have determined that the battery is caused such a damage.Battery is now change size and bulge on middle. I have contact seller with picture of faulty battery and they never answer for my emails. I have no income to buy a new phone any advise on this matter( any Authority to contact/complain ) highly appreciated. Unfortunately My phone is overseas model and not eligible for recent $55 screen repair.
For next time: Always go official samsung batteries. You can still get them reasonably cheap from ebay, even shipped from china but just make sure they are 'genuine', not 'battery for samsung s5'.
