Product received date, replaced in the phone battery replacement defective origin (no longer allowed to turn on or charge the phone) ... The phone charging and lights up again after installing this new battery. Is it provided an original battery? Difficult to say. To see if over time, it takes the load but at the moment 20 to repair a nexus 4 it's still a good solution.
Finally battery again down (a little over a month after installation). Back done, redemption, short congratulations to the seller and Amazon! Recommended date battery (we'll see ... hoping I fell a wrong number on my first order)
