Samsung vs Apple: A Closer Look at the 2020 Flagship Mobile Phones

The release of the Samsung Galaxy Note 10 and iPhone 11 Pro has brought an end to the battle of the 2019 flagship mobile phones.

If 2017-2018 is the time of full-screen display, then 2019 – 2020 is the time of 5G.

The leaked info of next year’s iPhone and Samsung has seen a huge change on the two flagship mobile phones, including design, hardware, etc.

Let’s take a look at it now.

Qualcomm has already released the snapdragon 865 5G processor and brought us numerous features.

One of the major changes is Dolby Vision which can dynamically adjust an image’s color settings to prevent the image from looking too dim or bright.

In the meantime, the processor also supports 200-megapixel cameras for better digital zoom, 960 FPS super-slow-motion video recording, and even 8K video as well.

Thus the early leakage predicted that Samsung S11 will have unbelievable improvement on its camera parts while the develop code is Picasso.

Previously, Samsung officially unveiled the 108MP ISCOCELL Bright HMX camera sensor in August.

In October, the leakage design also unveiled the secret of Samsung S11’s back camera and it seems that the phone will have around five “eyes” with a strange design.

Everything looks just fine except for the camera.

Samsung S11 Concep

Thus the early leakage predicted that Samsung S11 will have unbelievable improvement on its camera parts while the develop code is Picasso.

Previously, Samsung officially unveiled the 108MP ISCOCELL Bright HMX camera sensor in August.

In October, the leakage design also unveiled the secret of Samsung S11’s back camera and it seems that the phone will have around five “eyes” with a strange design.

Everything looks just fine except for the camera.

I thought Samsung was just joking whereas they were serious about it.

Samsung S11 comes with a large camera that integrates five individual camera sensors.

It is bound to be a powerful photography device.

In the meantime, the new system leakage screenshot proves that the new S11 will have a 120hz fresh rate setting option.

Together with the advanced 2K dynamic display with a crazy fresh rate, the Samsung S11 is supposed to be a phone with the best visual effect in 2020.

Thanks for watching…oh, there is one more thing.

What about the iPhone 12?

After Apple compromised the lawsuit with Qualcomm, Apple finally got the chance to produce a 5G phone in 2020.

It seems Apple will release six iPhones in 2020 including iPhone SE2, iPhone 12 4G, iPhone 12 4G Plus, iPhone 12 4G Pro Plus, iPhone 12 5G Pro Plus, and iPhone Pro Max 5G.

Right now have two common rumors about the design.

One predicted that the notch will be a bit narrower than before and Apple will fix it to reach a real full display in 2021.

Another opinion is that the new iPhone will use iPad Pro’s Face ID solution to fix the notch issue.

Both opinions believe the iPhone 12 will reuse the metal bezel.

Now, let’s move to hardware, it seems all the iPhone 12 series will come with an OLED screen and triple camera & TOF camera as well.

All phones will come with the A14 Bionic processor while the iPhone 12 Pro series will come with Super Retina XDR display.

iPhone 12’s main direction is to make a huge improvement in 5G, camera parts, and the stability of iOS.

There are a variety of bugs in iOS 13 and Apple has released so many patch versions to fix different issues.

Apple has already claimed that they will take the stability of the system as the main direction of iOS 14.

No matter how Samsung and Apple gonna change, 2020 definitely will be the new time for mobile phones.

Which one will you choose next year? Samsung or iPhone?

COVID-19 Protection and Stay-at-Home Tips
COVID-19 is an infectious disease caused by a new coronavirus introduced to humans for the first time.

It’s spread from person to person mainly through the droplets produced when an infected person speaks, coughs or sneezes.

These droplets can land in the mouths or noses of people who nearby.

These droplets are too heavy to travel far in the air- they only travel approximately one metre and quickly settle on surfaces.

This is the reason person to person spread is happening mainly between closes contacts.

According to WHO, the exact time that the virus can survive on surfaces is not yet known.

Take steps to protect yourself

Maintaining good personal and environmental hygiene is of utmost importance to protect yourselves from COVID-19.

Avoid touching your eyes, nose, and mouth with unwashed hands.

Clean and disinfect surfaces you often touch on a daily basis.

Performing hand hygiene is the prerequisite of the prevention of the spread of communicable diseases. Using soap and water or alcohol-based handrub can achieve hand hygiene.

You should go out less and reduce social activities, and maintain appropriate social distance with other people as far as possible.
- Wear a surgical mask when taking public transport or staying in crowded places.
- Take your temperature and that of family members with a thermometer everyday and watch for cough or difficulty breathing.
- If you have COVID-19 symptoms, seek medical advice right away – call ahead before you go to a doctor’s office or emergency room.
- Build up good body resistance and maintain healthy lifestyle. This can be achieved through balanced diet, regular exercise and adequate rest.
- Even in bad times, we have to keep learning and growing.
REWA ACADEMY: https://academy.rewa.tech/

How To Wear A Mask
- It should cover your mouth, nose and chin with the coloured side facing outwards.
- Pinch the metal edge of the mask so that it presses gently on your nose bridge.
- Remove a used mask holding only the ear loops.
- To be effective, change your masks regulagly or if soiled or wet.
- Wash your hands with soap and water after dispoing the solied mask properly into a bin.
And More To Fight COVID-19
- Reassure everyone that you’re protecting their health.
- This is especially true if you have a brick-and-mortar location.
- This may mean sharing your extra sanitation practices, putting a hand sanitizer station at the front of your location or implementing a policy where all staff wears masks and gloves.
- Be prepared to pivot. You need to be flexible to best serve your customers. Mailing service for cell phone repair may be a good choice.
- Make your employees or yourself a priority too.
- Don’t focus all your efforts on marketing during this time.
- The more you can put your employees at ease, the better they’ll be able to support your business and your customers.
May you all remain in good health and continue your daily life & repair learning in the global coronavirus crisis.

Troubleshooting iPhone X Won’t Turn On – Expert Repair Guide
Our previous blog has walked you through the work-flow of iPhone X Boot Circuit .

And you have learned that to have the phone turned on, working conditions like power supply, clock signal and reset signal are indispensable.

Since there are so many components involved in the process, reasons for won’t turn on of the phone can also be various.

Today we will explain the troubleshooting and repairing process of iPhone X by showing a real-life iPhone X won’t turn on case.

Follow our repair guide step and step and you can definitely learn something.

Analyzing

First, run cosmetic inspection of the motherboard.

The motherboard is not deformed or water damaged.

Then connect the motherboard with the DC power supply.

We can see that there is no current leakage.

Judging by this, the three main power supply rails, PP_BATT_VCC, PP_VDD_MAIN and PP_VDD_BOOST are in normal condition.

Continue to get the motherboard booted up with tweezers.

We can see that the boot current is larger than normal value.

We can confirm now that the fault is probably related to the 17 power supply rails outputted from PMU.

Motherboard Separating

Now we need to separate the motherboard to confirm whether the fault is related to the upper layer or the lower layer.

Place the motherboard on the specialized Heating Platform.

With temperature of the platform reaching the set temperature, pick up the upper layer with tweezers carefully.

Continue to take the lower layer off the platform.

Diagnosis

Now we can test the upper layer.

Connect the battery connector on the upper player with the DC power supply.

Then get the upper layer booted up with tweezers.

The boot current is still larger than normal value.

We can confirm now that the fault is related to the upper layer.

So our next step is to check the 17 rails outputted from PMU one by one.Let’s start with PP_CPU_PCORE first. Locate C2701, one of the test points of PP_CPU_PCORE on Refox.

Then run diode mode measurement of a capacitor on C2701 relevant circuit.

The measured value is normal.

Continue measuring test points of the remaining 16 rails.

Judging by the measured value, PP3V0_NAND has shorted.

Since there are many components on PP3V0_NAND, we can locate the faulty component with rosin detecting.Dip some rosin with the Soldering Iron at 350℃.

Then smoke rosin on components on PP3V0_NAND.

Set the output voltage of the DC Power Supply at 3V. Get the black probe grounded.

Meanwhile, get the red probe touched with a capacitor on PP3V0_NAND.

We can see that rosin on C2649 melts immediately.

Judging by this, C2649 has been damaged.

Troubleshooting

Let’s try to detach C2649 from the board and see how it works.

Remove black adhesive around C2649 first.

Then we can just remove it with tweezers slightly.

Again, get the red probe grounded.

Touch the two pins of C2649 with the black probe.

The measured value is normal.

We can confirm now that the shorted condition is caused by damage of C2649.

Still, we need to test the upper layer.

Remove the upper layer and clean with PCB Cleaner.

Connect the battery connector on the upper layer with the DC Power Supply.

Get the upper layer booted up with tweezers.

The boot current is normal this time.

Motherboard Recombining

Next thing we need to do is to solder the two layers together.

Remove heat insulation adhesive on the lower layer first.

Then place the lower layer onto the heating platform.

Power on the heating platform and apply some Paste Flux to the third space PCB.

Then get the upper layer in position.

Reassemble And Test

Get the display assembly installed.

Connect the battery connector with the DC Power Supply and get the motherboard booted up with tweezers.

The boot current is normal.

The phone comes with normal display and can get access to the system. Fault cleared.

Coronavirus Q&A: Product Pricing, Logistics, Delivery Time

In response to the outbreak of coronavirus, REWA has been equipped with the necessary preparations for the resumption of work on January 25.

On February 10, the official back-to-work day, REWA carried out basic daily work in an orderly manner according to the actual situation of departments and staff, under the premise of ensuring the safety of all employees.

Right now, REWA is adopting a home office and on-site office to provide excellent service to our clients.

About Placing Order

Please note that orders placed now are arranged according to their priority.

Order now and get your order arranged first!

Supply Chain

Although REWA has been equipped with some inventories, the supply will be tight for a certain period due to the delay of factories in production resumption and some products will come up with long-term shortages.

Price

Because of the shortage of supply and the short-term delayed production, the price of some products will rise until the supply is restored(April or so).

However, the price of some hot-selling products like the Laser Separator Machine will be a surprise for you at this time.

Delivery

Due to the instability of supply and delayed resumption of work of some staff, the delivery time of the order will be longer than usual.

Please confirm your order plan with our sales in advance.

Logistics

Although air freight from Hong Kong is normal, there might be a delay in logistics.

Therefore, REWA highly recommends you place your order in advance and prepare more to avoid out-of-stock and reduce losses due to price increases.

The COVID-19The coronavirus is highly contagious, but the fatality rate in areas with adequate medical conditions is not high.

The Chinese government has taken effective measures to control the epidemic, but given the incubation period and infectivity of the virus, it is expected to reach a peak at the end of February and then be completely controlled in April or May.

During this period, all walks of life will fight COVID-19 while resuming business and production.

Pair two sets of AirPods to one iPhone and enjoy the same song or movie along with a friend.

Share Sheet

Some minor design changes have been made to the Share Sheet in iOS 13, tweaking the colors and adding some transparency.

Redesigned Voice Message Icon in Messages

When using the option in Messages to record a voice-based message, there’s a new icon for the option. It’s now a waveform rather than a microphone icon.

New widget Edit button design

When editing widgets in the Today View, you’ll see a new look for the edit button, which is now pill-shaped rather than circular.

Security bug

Closes the vulnerability that allowed unauthenticated access to passwords in Settings.

What’s your favorite new addition in iOS 13 beta 4? Sound off down below with your thoughts. Also, be sure to have a look at our previous iOS 13 new feature list.
