With the development of the mobile phone industry, the number of mobile phone users is forecast to reach 4.68 billion in 2019. It’s not surprising, therefore, that mobile phone repair possesses a large market capacity.
With years of professional experience in mobile phone repair, REWA has trained hundreds of repair technicians to power their repair businesses. There is no doubt that these technicians have craftsman level skills, but REWA can provide them with catalysts to help them become successful technicians. Shakespeare claims that “Eyes are the windows to your soul”. While REWA believes that “Microscope is the window to technicians”.
Take a look at our premium 1080P Electron HDMI Stereo Trinocular Microscope. It can be used not only for industrial inspection but also for PCB/ metal inspection. Compared with standard microscopes, the high-resolution graphics output of our Microscope can increase the accuracy of your repair work.
Rosin and freeze spray are two common ways used for fault-finding.
Although these two ways are cost-effective, it is difficult for us to instantly locate the faulty component with the help of the two. It’s time to change. The cámara térmica de infrarrojos can directly increase efficiency of repair work. Thanks to the intelligent analysis software, it can effectively monitor temperature of each chip. What’s more, the advanced imaging tech that combines visible light with infrared thermal imaging can also achieve different visual effects.
You might feel angry or even mad when you spend endless time organizing different screws, repair materials, etc. Why not try the integrated mobile phone repair platform? The giant platform comes with an Aluminum base and a heat-resistant silicone pad. The point of this platform is that it can not only gather up different repair tools (including the microscope) & components but also features anti-static functionality.
After our brief introduction of these effective “catalysts”, you may still have no idea what repair tools you should choose. Don’t worry. Here we present you two repair kits, the “Ultimate Kit” and the “Standard Kit”.
Ultimate Kit
The Ultimate kit includes a 1080P Electron HDMI Stereo Trinocular Microscope, an Infrared Thermal Camera for Mobile Phone PCB Troubleshooting and a Giant Integrated Mobile Phone Repair Platform. The kit comes with the best output graphic quality and it is expensive than the standard kit.
Ultimate Kit
Let’s Move to the standard kit. It includes a standard Trinocular Microscope, an Infrared Thermal Camera for Mobile Phone PCB Troubleshooting and a Basic Integrated Mobile Phone Repair Platform. Compared with the ultimate kit, the graphic quality of the standard Trinocular Microscope is relatively general. However, it can also ensure the correct operation of your repair work. The basic platform is also smaller than the platform in the ultimate kit. All in all, the standard kit is more cost-effective than the ultimate kit.

Can iPhone 11 Pro possibly be turned into iPhone 11 Pro Max?
It is actually theoretically possible.
With pins of the two phones’ display connector and touch connector functioning almost the dame, we can turn an iPhone 11 Pro into an iPhone 11 Pro Max by changing board ID resistors.
Today we will try to turn iPhone 11 Pro into iPhone 11 Pro Max.
iPhone 11 Pro VS iPhone 11 Pro Max
iPhone 11 Pro comes with a 5.80-inch touchscreen display.
iPhone 11 Pro Max comes with a 6.50-inch touchscreen display.
What will happen when we connect the iPhone 11 Pro Max screen with the housing of iPhone 11 Pro directly?
The backlight of the iPhone 11 Pro Max screen displays normally. However, the screen comes with horizontal lines.
Judging by this, although pins of the two phone’s display connector and touch connector function almost the same, the difference between driving programs of the two screens can still result in horizontal lines on the screen when iPhone 11 Pro Max’s screen is connected to iPhone 11 Pro’s housing.

In the modern tech-driven world, everything seems to revolve around speed and about being quick, quicker as compared to competitors, quick enough to get everything done, and quick enough to get some free time despite hectic schedules. Until some time back mobile applications were reserved for large businesses and corporations. Currently, smaller businesses and organizations are becoming smarter and well-equipped serving customers better and obtaining greater ROIs because of mobile apps. Human beings have an inherent urge to be social. No one wishes to be alone and secluded from the rest of the world. You simply cannot deny that mobile is social. We know that today, businesses could be boosting sales via mobile devices. Setting up a functional Twitter or Facebook account could be a wonderful idea but that simply is not good enough.
Businesses have today concluded that they need apps. The fear associated with high-priced mobile app developers is no longer a deterrent; hence, there is no reason to do without a mobile app. Businesses could make the most of their apps thanks to perfect planning and a clear idea of what exactly you are thinking of getting from your mobile app. You simply need to describe your goals and then just prioritize them right from the start. You could use one or all of the following paths leading to obtaining a highly functional and customized mobile app. The four paths are service & support, customer engagement, online sales, and customer engagement. Once you know precisely what you are looking for, you would soon realize why you needed to have a mobile app for your business. Let us explore some of the advantages of having a mobile app for businesses.
For Establishing Direct Communication & Effective Geo-Targeting Marketing
As per www.carmatec.com, Mobile apps are known to be effective and quick in grasping customer attention and engaging customer interest. They are great for direct and prompt communication about product launches, promotional offers, new services, discounted rates, and improved features. All this direct communication could help you to obtain important information like geographical locations, demographics, and shopping behavior in terms of your products, as well as, services, thus assisting you to assess the overall market demand and enhance your marketing and sales strategies.
Boost Visibility to Customers at All Times
In the United States, the average individual spends more than two hours on his phone every day. There are over 1 billion smartphones worldwide. Hence, from the perspective of businesses, it is great to know that people are spending more and more time on their mobile phones as compared to PCs. Businesses simply need to modify their marketing strategy to complement or match this slight shift.
Your business would get a wider exposure if you are successful in building a reasonable mobile presence. Your company’s name, image, and logo must be visible when people are scrolling, unlocking, or doing whatever on the go. We use mobiles while traveling to work and coming back from there or even while watching television every evening. These are supposed to be great times for sending notifications to your potential customers. If you are offering Internet-based products or services, you must consider using a mobile app for making sales. You must focus on offering valuable solutions to your clients remotely. You could use mobile apps to connect with reputed lending services such as libertylending.com for fast and perfect solutions.
Build Solid Brand Recognition
Whether you are having a brand new business or you are simply re-branding, you could consider boosting its recognition and image using a competent mobile app. You simply need to develop an app having likable features for fascinating your target audiences. You could consider building a functional app instead of using a costly billboard. It is a fact that many people do not pay attention to the messages showcased on billboards.
Encourage your customers to interact actively with your app. The more frequently they would be interacting with it, the more they would develop a liking for your new products and brands sold by you. According to the experts if the customers frequently see your brand, for instance, 20 times or more, then it is properly noticed.
Today, mobile apps have sharing options and they could easily share a brand’s communication with their close friends and family. It is just like a friend informing you about an amazing product or service he had come across. We know that studies reveal that third-party sales and referrals seem to be a truly effective and valuable marketing stratagem.
Boost Customer Engagement
All customers require reaching the company that sells something they are looking for. If a business seems unreachable, you would be encountering the risk of losing your prospective customers. We understand that a mobile app could be of great use in enabling this reach. You could consider having a Help Desk on precisely the mobile platform for customers to post their queries, comments, orders, complaints, etc. If you are in a position to respond to your customers individually and on your own, then your customer engagement would be exceptional. Make the ordering or even the booking procedure pretty simple but secure. People do not like the idea of lengthy procedures. They are more likely to click the button marked Back Button as compared to clicking the Next Button.
Stand Tall Among the Rest
A mobile app could help you in standing tall among the rest. You must make the most of this effective marketing tool. By the time your competitors start recognizing its importance, you would have captured the majority of the market share. You could then stay well ahead of the competition. You would be winning a lot of respect among your peers.
Boost Customer Loyalty
Customer loyalty could be achieved when they are constantly reminded about your products and services. We know that there are already too many advertising efforts out there. Instances are roadside banners, billboards, emails, flyers, flashing signs, coupons, and social media marketing, etc. Do you think it is wise to include more communication in this already crowded place? Your message could get lost or even forgotten in this overcrowded place. In this context, it is essential to realize that a mobile app would truly help in developing a sincere and robust bond between your clients and your business.
Conclusión:
Mobile apps create huge possibilities for businesses today. Persuade your customers to download your business’s app on their mobile devices and smartphones. You must use the app for generating profitable opportunities.

After we post Samsung Galaxy S7 edge Glass Screen Replacement Guide, I often heard many people said their Samsung Galaxy S8 no speaker sound. So we released this guide to solve this problem.
When your Samsung Galaxy S8 or Galaxy S8 Plus no speaker sound or audio, it will be a frustrating issue, your smartphone will become an electronic reader.
So what should you do? First, you need to know what happened on your phone, there are also three common problems such as your Samsung Galaxy rings but speaker won’t work for other applications; you might not hear any sound with music, apps as well as calls or the Samsung Galaxy S8 gets stuck in the headphone mode.
So how to fix No Sound Or Speaker on Samsung Galaxy S8?
Follow the steps below one at a time and you should be able to fix the issue with your phone.
1. Your Samsung Galaxy S8 might have the Silent/Vibrate mode enabled.
This is a funny thing when you are anxious about your S8 no speak sound.
When you found your Samsung Galaxy S8 audio not working, the first step you need check your volume case.
You can check this by using the drop-down menu using your fingers to slide down the screen from the top.
Press the volume key and when the volume slider appears on-screen, tap on the small down arrow at the end of the slider to see all the volume controls for Media, Ringtone, Notifications and System.
Go ahead and turn all the sound settings up, turn it to Loud Mode.
2. The headphone jack may be blocked
If the step 1 can’t solve this question, the headphone jack may be blocked, you can clean your headphone jack and speaker grill to make sure there is no lint, dust and dirt which can prevent you from getting any sound.
Any dust, dirt or grime blocking the charging port can result in a poor connection which might eventually lead to sound and charging issues.
3. Close the Bluetooth
If your Galaxy S8 smartphone to other devices via Bluetooth.
Ghost connections still remain even after aborting a Bluetooth connection.
These ghost connection sound issues when you try to play back a sound file.
You can fix this issue by simply turning off the Bluetooth toggle from the Bluetooth settings.
4. Restart your phone
Use the power button options to restart your Samsung Galaxy S8 or Galaxy S8 Plus.
Select the option to restart the device which should hopefully get rid of any glitches that are resulting in the sound issues.
5. Software update
Check to ensure that you have the latest software update on your Galaxy smartphone.
You can do this by following the directions below;
Settings > About device > Software update > Check for updates.
If there is a new update, download it.
Different carriers release updates at different times.
6. Factory reset
If all else fails backup your phone and do a reset.
Go to settings, General management, Reset and then factory data reset.
Factory reset is the last option that can resolve all kind of issue including the S8 sound problems.
So head towards Settings > Backup & reset> Factory data reset > Erase all data.
Wait for few seconds as this will take a few minutes to erase everything from the device after which you are required to set up your Galaxy S8 from scratch.
7. Turn on ‘Prevent USB audio routing’
Enable the developer option in your Galaxy S8 by going to Settings> About device and tap the build number seven times.
When the developer option is enabled, head to Developer option and scroll down to get the Media option.
There you will notice an option ‘Prevent USB audio routing’.
Turn this option on by toggling the switch.
This method has worked for many.
So, you too can try this out if it becomes helpful for you to solve the audio issue.
8. Boot in safe mode
Turn off the device first
Next, press Power button for few seconds till you notice Samsung logo on the screen.
Release the power key then and hold down the Volume down button till the phone completes restarting and safe mode appears at the bottom left corner of the screen.
If the audio issue is not noticed in safe mode then a third party app is the main culprit.
Uninstall third-party apps on by one until the problem is solved.
Our suggestion is to start with the apps you installed recently, right before the issue occurred.
So, these are the methods to resolve the Samsung Galaxy S8 audio issues.
You can try them out, but if nothing works, the possible situation is that your speaker is broken in which case you will need to have it changed or replaced.
You need to read the next solution:
Reparación de la placa lógica del Samsung Galaxy S8 sin sonido del altavoz
Usually, Damage of the speaker or malfunction of the speaker circuit can result in this issue.
We need to confirm whether the speaker is in a normal status or not first.
If yes, then continue to run diode mode measurement of the speaker contacts.
And we can relate the fault to audio amplifier IC with the measured value of one contact being abnormal, At last, we complete the repairing work by replacing a new audio amplifier IC.
Next watch our video guide:
When we get a No Speaker Sound Samsung Galaxy S8, we need to check it first. Turn on the phone and open the Dialer app, key in ‘*#0*#’ to access the diagnostic menu, and tap on the ‘Speaker’ button, we found there is no audio output of the phone. Now we are sure the Samsung Galaxy S8 no speak sound, so we need do the next steps.
Primer paso: Check if the speaker is in a normal status; disassemble the phone and take out the speaker, measure resistance of the speaker, we found the measured value is normal, So the fault might be related to the relevant circuit of the speaker;
Segundo paso: Take out the logic board, put the logic board under the Microscope, check if speaker contacts and components around have been damaged or loosed. The result shows all going well;
Paso 3: Switch the Multimeter to diode mode, measure two contacts of the speaker,
The measured value of one contact is 502, which is abnormal The other contact 802, which is normal Since the two contacts are connected with audio amplifier IC via inductor
Paso 4:
Our next move is to check the audio amplifier IC
Attach the logic board to PCB Holder, apply some BGA Paste Flux to the audio amplifier IC, heat with Hot Air Gun at 330℃, air gear2;
and detach the audio amplifier IC from the logic board, then clean bonding pad with rosin wrapped Solder Wick.
Once done, clean with PCB Cleaner, run diode mode measurement of Pin E5 and Pin E6 on the pad, check whether the internal circuit has been short-circuited.
Result: No short-circuited condition
We can confirm now that the fault is related to audio amplifier IC, and we need to replace with a new IC.
Paso 5: Replace with a new IC.( watch the video to get detail )
Apply some BGA Paste Flux to the bonding pad
Align the new IC to the right place
Solder with Hot Air Gun at 330℃
Una vez hecho, limpiar con Limpiador de PCB
Paso 6:
Run diode mode measurement of the two speaker contacts, the measured value is normal, assemble the phone.
Test:
Turn on the phone and open the Dialer app, key in ‘*#0*#’ to access the diagnostic menu, tap on the ‘Speaker’ button, and we can find the audio output of the phone is back to normal.
