Your service is NOT good at all, so POOR, WORST ever probably because the technicians working there have no knowledge about software and hardwares.

My Lumia 520(3 months old) has a problem, it restarts randomly once every day. Not sure when but I can tell you that it happens for sure, because whenever it restarts, the sound volume level resets to 15, and always I have to set it to 21. It is so annoying to have such a melon, so I decided to give it to Nokia Care to identify the problem after trying all those steps like resetting to factory settings, checking the battery and all other things like changing the sim card etc.

At Nokia Care, they said that there is no problem with the hardware, so they upgraded the software(OS). But after returning home, I checked the OS version, it was the same as earlier, which is the latest already. Few minutes later, when I was using the phone(One Note), it restarted again.

This time, Nokia Care guys told me that they are going to use the phone for couple of days to observe the behavior, then only they can send it for repairing if they find any issue. I got *****off, asked them whether they are going to look at the screen constantly all the time. They said that is the only way to find if restart happens automatically. However, I could not let them use the phone for such dumb testing. Probably because you don't have any software or hardware tools to find out such fault! That is hilarious. I just wanted a replacement for that it you couldn't find the issue rather then doing random tests on that.

Okay I am now going to live with this until I buy a new phone, won't be obviously Nokia. Till then I will suggest each and every person I meet not to buy such craps(services are poor too) to end up in such a situation. I am going to post it everywhere, whenever I find time to do so.

All I need is a replacement. Again, it will be your decision whether you want to replace it or not, but one thing is sure, I will make sure that people know about it how pathetic your service is. It's again because, the technicians couldn't identify the problem, now they want to use the phone for couple pf days until they see a restart, and when they see it, probably they would send it for repairing. As per them, this proces might take 10 to 15 days. If they don't feel any problem, they would return the device without sending it for repairing. My question is, do you perform such DUMB testing on a SMART phone? What if that guy is sleeping when the phone restarts? lol. Don't you have any software or hardware to identify the fault? If no, tell me how your guys at factory going to solve the problem?

Whatever it is, I need this device to be replaced ASAP, because it's just 4 months(actually less when this problem started a month back) old.

Afterall, it is all about the ethics a company can have in their business. People will know about it how ethical your business is, if you talk nonsense in such cases.
