My S7 Edge seems to have the common flickering issue with the screen. I have the international model and Samsung won't...

I have an issue with my iPhone 6. When I call people and use the phone next to my ear, the mic does not pick up anything...

You can try to find an OEM used display pulled off a used phone here on iFixit or on eBay. Be sure to clean the connectors with isopropyl alcohol to remove any oil that my be interfering with the connection to the displays.

Start with the bend. There is probably an IC around the bent area that has a damaged solder connection.

You will need to replace the dead 12S1P pack of A123 26650 cells with new ones by spot welding a new pack together. Here's a battery diagram.

You should not have rooted it without realizing the risks... Was the issue after you attempted to root it? How can we help you replace a motherboard you won't be able to get? Ask XDA forums.

Try reattaching the LCD connectors inside the phone. You might have to buy a new screen if that does not fix it.

Try holding the volume down and power button until the phone resets and turns on again. If you didn't have any physical damage, the screen could have just turned off for some reason.

I doubt it. It is worth so little.

No point really. You could find one on eBay but it is not going to be a big improvement. Can you get the largest sized ram for just 1 slot?

With the device turned off, press and hold the Volume Up and Power buttons until the ZTE logo screen appears, then release. Press the Volume down button to highlight wipe data/factory reset. Press the Power button to select. Press the Volume down button repeatedly until Yes -- delete all user data is highlighted. Press the Power button to select. Wait as the device resets.

Is the diagnostic port 6 pins or 5 pins?

Surprisingly easy for Apple.

The battery is Li-Po and not Li-ion tech which is more safer and lasts longer. I'd rather have the iPhone battery still. Lasts just as long in my experience.

Do you have to remove the battery to remove the motherboard? I just need to remove the motherboard for soldering.

You need a special cutting machine, besides there doesn't seem like there are any replacements on the market atm.
