it's been a while since you have posted your comment, but did you try to reflow your phone? mine has a problem with the SIM card and i tried every other solution except for this.
not sure if i should try this and risk damaging a phone that could otherwise be used for multimedia purposes.
I picked up a couple fixer upper LG G3's listed in local classifieds over the last month to tinker with. One I found for 25 bucks with the infamous screen flicker issue. 35 bucks for the other which had a toasted Sim and SD card reader. I swapped out motherboards, thinking the flicker was related to the LCD and I'd have at least one good device.
Long story short, both phones now work. I think for the most part the screen flicker was related to the connection ribbons themselves. By simply disconnecting and reconnecting them it corrected the problem. Whether it was due to loose connections or some other strange phenomena, it worked and has for over two weeks now. With a 3 day weekend to keep myself occupied I applied my Google skills in an attempt to fix the second board. I came across several threads which discussed baking motherboards, so with nothing to loose I tried it on the SD/Sim card problem board.
I removed the motherboard, made a tin foil rack out of bamboo skewers to lift it off the surface, placed it on a cookie sheet in an oven preheated to 350 f degrees. Baked for 8 minutes (350 f for 4 minutes, turned up heat to 380 f for the remaining 4 minutes). Took it out and let it set for 15 minutes. Two days later ... Still functioning.
I'm now monitoring thermal temperatures, as per other threads espousing the wonders of heat sinks. On average both boards' CPU's run between 100-120 f (no modifications) with normal use. Though I'm not sure what the normal temp should be, by comparison my Droid Turbo under similar conditions runs about 20 degrees cooler. I don't know if the issues the LG boards had were related to overheating or to the flex ribbons ... or a combination of the two ... but baking did seem to cure the Sim and SD card issue, as the pins weren't bent or dirty to begin with. Wife thinks I'm a freak but hey, live and learn.
Update: Three days later, still works.
Moral of the story: Use at your own risk? Your results may vary? Keep the Droid, get rid of the LG3's? Naa... no moral authority here. It's just a damn phone right (and strange obsession).
