I've been rather suspicious about the unreliability of my 1520, with several of the spare parts I've received being faulty (or going faulty quite quickly).
The first time I broke the screen, the replacement had some very noticeable white blotches towards the upper centre of the screen. The original screen didn't have that. As it happens I broke the blotchy screen, too, and this time the replacement was fine. So, 1 in 2 of the screens I bought was faulty.
The USB board at the bottom of the phone seems worse. The microphone used for phone calls started working intermittently on mine, so I replaced the USB board (which has the microphone on it, plus some other stuff). It worked OK but after only a week one of the LEDs stopped working. The replacement for that also worked OK for several weeks, but then the microphone stopped working. I ordered another replacement and - from new - the microphone wouldn't work. I then started ordering them in pairs, from different suppliers. The one that arrived a couple of days ago was faulty from new - the right hand LED wasn't working. Another has arrived this morning and I haven't tried it yet - I'll let you know.
I strongly suspect that many of the replacements we can buy on eBay are rejects from the manufacturers - ones which perhaps failed some aspect of the QA process - and have found their way onto the market. The ones I've bought so far come from various eBay suppliers, and typically cost around ?16 or so. I have seen one supplier on eBay who are in China and claim their USB boards are genuine, original, OEM parts and they cost more than twice as much - ?35.
Of course, every supplier claims "genuine OEM", but the higher cost of these in China makes me wonder if maybe these are of better quality and reliability.
Has anyone else noticed a problem with dodgy replacement parts for the 1520?
