Solution 4. Handle water stains
 

You must wipe the iPhone exterior, taking the assistance of cotton cloth. Don't apply too much pressure while wiping the phone to minimize the iPhone water damage, it can avoid spreading the liquid around.
 

You can shake the iPhone and you can blow into the iPhone openings. You can also try compressed air or a blow dryer on cool. You can also try using a wet / dry vacuum to suck the water out.
 

Solution 5. Put the iPhone in a dry place
 

After clearing its exteriors, you need to place the iPhone in a warm and dry place. This would evaporate the water content that is inside the iPhone.

How to Repair iPhone 6 LCD Screen Display

What should you do when you need to repair the iphone 6 LCD screen display. Turn on iPhone 6 to test, the iPhone LCD screen doesn't display. Disassemble the iPhone motherboard, and observe it under the Stereo Zoom Microscope, we found there are many solder paste on iPhone display socket and iPhone touch socket.

 

Is the iPhone LCD screen not display because the socket is not clean? First we use BGA clean water to clean the iPhone motherboard. Because the customer said that iPhone LCD screen also is half bright and half the screen black state, so, after cleaning, we can use digital multimeter to measure the grounding resistance value for the J2019 display socket 1 pin PP_LCM_BL_CAT2_CONN and 4 pin PP_LCM_BL_CAT1_CONN, these two pins will cause iPhone screen half bright and half black problem. We found the resistance value of 4 pin is 2111, which is abnormal, the normal resistance value is about 570.

After a short connection of the FL2025 fuse inductor, the resistance tested is normal.

Assemble the iPhone display screen and test it, the Apple logo can be displayed normally, but the backlight still not bright. We noticed that the CPU shield cover was been moved, remove the CPU shield cover, we found the CPU was been repaired. Now, it's easy to explain, the U1502 backlight IC is virtual welded when blowing the CPU by QUICK 861DW hot air rework station, and it leads the iPhone LCD screen sometimes bright and sometimes not. Also, there are many solder paste and tin balls, which is easy cause iPhone motherboard to short circuit.

Clean up the tin balls and solder paste, and then remove the iPhone backlight IC. There is a good way to remove the iPhone backlight IC, remove the three filter capacitors above the backlight IC, and then the iPhone backlight IC is easy to remove.

Reballing tin and then install the chip, assemble the iPhone and test it, the fault has been solved.

What to Do When iPhone 7 Plus Camera Failure Repair

Last week, one of my customers asked me how to repair the damaged iphone  plus camara, after that, i told my engineer, he told me how to repair it, so i write this to help you to repair your iphone. This iPhone was repaired before, the previous phone repair shop repaired the iPhone WIFI module IC and U3301 iPhone audio IC. According to previous repair experience, we know there are 2 camera power supply transfer tube on the WIFI IC are easy to virtual weld, after remove it, and reinstall it, the failure still there.

Use digital multimeter to measure the grounding resistance value for iPhone rear camera J3001 and J4501, the data is normal. And the power supply for camera socket tested also is normal.

Measuring the I2C bus on J3001 and J450，when measured the J3001 2 pin, finding that it only has 0.4V voltage, but in the normal case, the normal voltage of I2C bus should be around 1.8V. Open the WUXINJI Dongle to check iPhone schematic diagram, this I2C bus via safety resistor R3301 to M2600, pull-up supplied by R4604 resistor.

Combine iPhone bitmap to find R4604 resistor.

One side of the resistance value measured of R4604 is normal, the other side is 0.4V, which is obviously wrong, we suspect the pull up resistor is damaged. With the help of the QUICK 861DW hot air rework station and tweezers, we replace the pull up resistor, and the measure it again, now the both sides voltage of resistor are back to normal.

Enter the systems and test it, the failure has been repaired!

How to Make Your Phone Work Well

We are now living in a new era when phone dominates, we can see a lot of smartphones in our daily life, so we cannot live well without a smart phone. For example, we love the apps stored in our handset, but how many of us think of booting the device periodically to ensure that it is not hung every now and then. For those who wish to make the best use of their much-coveted phones, here’s a sneak peek into the tips and tricks of smartphone protection and long term use.

Smartphones should be restarted often

With the advent of social media platforms, it is obvious that you will stay hooked to the phone every time. Basically, smartphones are mini size computers so a lot of memory is expended while you work on it. Doing that for a prolonged time requires a restart every time the programs are no longer running. Also, you can prevent few glitches that can lower down the overall performance of the phone.

Time lowers the functioning capacity

In other words, it is wise enough to accept that smartphone memory withers with time. Since operating systems are designed and updated with their fast processors, greater memory, high end cameras and the like, it is likely that performance will not be the same after some time. After all, the features need to be updated timely but even then it is not possible to have the same initial speed.

Be wary of covers and cases

While a lot of the emphasis is given on smartphone protection using covers and cases, problems are bound to arise with aftermarket cases. Not that they won’t offer good protection but accessing can pose a difficultly or the screens and buttons may become unresponsive after some time.

Video kills data allowance

If you wish to get the most of your phone, cut down on streaming music and games online. It’s better to resort to iphone Wi-Fi connection instead of normal data. This is primarily because these apps drain the phone’s memory considerably (like one HD movie can take up 700 megabytes of data).

Most shoppers are largely concerned about the smartphone model they wish to keep or flaunt before others. With these tips and tricks working good for many, it’s time the others will also act accordingly for rendering total smartphone protection and maintenance.
