Chosen Solution
Hello to all I have a real curly one this week My N7105. I decided to get the S5, so did. Decided to sell the N7105 But had it for a couple of years with no problems but normal thing, was looking tired Replaced the mid frame Charge port flex (Original Part) New Battery Did not do anything with the phone for a few months, just lived in the office Other day got it out the draw and decided to sell it so checked it and found that the wifi reception was weak, there was no sound unless you used head phones Phone is unlocked as I originally bought it outright but always with the same courier Tried it on another courier and worked, The one with the strongest signal in this area but the signal was weak so put the old sim in, the one in my present phone. Signal was weak too, Charged beautifully Then had a break on that and checked the Sound. Nothing! ugged in the headphone, works great. So did the plug in and out trick, no did not work. Hard Reset did not work . All settings in phone are OK Also got the Circle with the bar through it up where the signal usually is. Checked the settings, not checked Charge port flex connector looks OK ‘‘Could the flex cable be responsible for all of this??’""""" My nails are getting shorter Recap: Weak Signal, No Sound except with Headphones Weak Wifi Signal
When you mean by Charge port flex (Original Part) did you buy the exact same model number one? Because if you buy a slightly different one it can cause all these issues.
