The board was shown after the second breakdown. In order to remove this shitty filter, I had to bite the screen. The first time I opened the lid and the screen and warmed up with warm air from the soldering station, the same SAW filter that popped up over the board fell down. I collected everything with a thought and broke it completely .And it worked in full functionality. And wi-fi and GPS too. By the way, having seen the pop-up filter, I remembered a hundred this place on the screen was very hot when using navigation software, for example Yandex traffic jams. It immediately became clear why. Satisfied, I began to use it again I’m Yandex and WIFI. But the heating that started again guarded me and led to the second autopsy of the miracle of American technology, about a week later. Again the Wi-Fi and GPS disappeared. By the way, the Wi-Fi and blue tooth addresses were always visible in the device’s properties, which suggested that the chip the one responsible for them is fine. She, by the way, sits on the opposite side of the board, under this filter. The second time I decided to dismantle it and inspect it. As the screen interfered with it, I slightly bit it with side cutters and unsoldered the filter. The inspection did not give anything outwardly normal.everything is back. But it doesn’t work, I’m looking for this infection I read datasheets. Most likely it’s Murata SAFSE1G57KA0T90. At least for me, but I understand that you can shove anyone for GPS if you just climbed in. Judging by the posts and information in net, there may be another vendor is looking and looking for a while. And he most likely laughed from falling shock when falling inside. Although I carry all the phones in their cases, I dropped the iPhone a couple of times a year. What is most surprising is that the second Nokia E90 phone dropped ten times more. Since I use it at work, (iPhone for family and family calls s and mobile Internet, in view of the good tariffs for GPRS, provided it is used). But he didn’t break anything with the same year, it also works with GPS and WIFI. Maybe these filters aren’t there. :)
