My 3.1 plus was dead on 27th Sept. I submitted it to nearest service centre and they were kind enough (after claiming water damage without even inspection) to replace phone's motherboard within warranty. All was well except no security patch update. I had August patch before phone was dead. Post revival, phone was stuck at July patch.
On 19th Oct phone was dead again. Phone is still under warranty till Dec end. So I went to service centre to get it checked. They said some screws are missing near the speaker grill and motherboard had minor scratch. They claimed that either I tried to open the phone or got it opened from someone else and they will not cover the repairs under warranty. This response came to me as a big shock. I am no engineer or a curious cookie who will dare to play around with the internals of a phone which is under warranty.
I tried convincing the centre manager that those scratches is not my fault. He asked me to submit the phone and wait for the call back.
Have you guys experienced something like this or some other serious issues with service centres?
