The Samsung Galaxy S21 was announced in Samsung’s Galaxy Unpacked event on January 14th, 2021 and released on January 29th, alongside two other Galaxy Phones and a new pair of Galaxy Buds. The Galaxy S21 starts at $799 and comes in four colors: Phantom Violet, Phantom Grey, Phantom White, and Phantom Pink.

Compared to the Galaxy S20, the S21 has only a few minor changes–most of them downgrades to reduce the price (S20’s starting price of $999 to S21’s $799). Most notably, the rear cover is plastic instead of glass, which makes removing it easier. The screen is still 6.2 in with a 120 Hz refresh rate, but its pixel density dropped from 563 ppi to 421 ppi, the 1440x3200 resolution to 1080x2400, and the 89.5% screen-to-body ratio to 87.2%. The Galaxy S21 also weighs a little more than the S20: 5.96 oz and 5.75 oz respectively. To make up for this, the S21 boasts a Snapdragon 888 processor with integrated 5G modem and a 3D Sonic Sensor Gen 2 in-display fingerprint sensor with widened surface area, both from Qualcomm.

Internally, only three changes stand out as being important for repair: the vibration motor, the upper midframe, and the rear-facing camera adhesive. The Galaxy S20 has its vibration motor located near the bottom-left of the device brushing up against the USB-C port/daughterboard. Instead, the S21 has the vibration motor in the upper-left corner nestled between the motherboard and edge of the phone. To get to the vibration motor, you have to unfasten the upper midframe, which has almost double the amount of screws of the Galaxy S20; the upper midframe holds the motherboard, the camera assembly, and one 5G antenna in place. Finally, the rear-facing camera is protected by a risen-shell connected to the rear case and secured to the phone with strong adhesive.

Mobile Phone LCD Parts wholesale – High quality iPhone LCD, Samsung LCD, and iPad LCD screen replacement at wholesale prices at Wholesale Phone screen Refurbishing factory from…

After Samsung, iPhone screens tend to be the ones that require frequent repairs. This could be because iPhone screens are made of glass - they crack pretty easily if subjected to rough usage!

There is no dearth of iPhone replacement screens in the market. Such is the quality of the ‘high copies’, that it becomes extremely difficult to distinguish it from the original!

All original Apple screens are manufactured by LG or Sharp, whereas the high copies are manufactured by aftermarket companies such as Longteng (IVO), TianMa, ShenChao, KingWo (Teevo), JingDongFang (JDF/BOE) and AUO.

Let us take the example of an IVO screen. A company first contacts IVO and asks them if they can produce a kind of LCD for their phone. They cannot ask IVO to develop LCDs for an iPhone outright - this could lead to copyright and patent issues with the parent company, Apple!

IVO and the company will sign an agreement, post which the company asks IVO to study the LCD in question. Once IVO produces the LCD, the company will ask its own factory or a third party’s factory to assemble the screens and proceed to sell.

Once the demand for these screens builds up, the company looks for other factories to assemble the screens for them, and continues to sell them in the market.

Eventually, the company will not assemble the screens themselves, as more brands keep coming in. They will directly sell the IVO LCDs to certain factories. These factories purchase the spare parts like the glass, frame, backlight, OCA, etc. themselves, and assemble the LCD with these spare parts.

To create a more effective cost-benefit ratio, and to compete with other similar factories, they may use different grades of spare parts, resulting in the differing quality of LCDs. In fact, the quality of Aftermarket LCD depends not only on the LCD, but also the quality of the spare parts used.

While it is always ideal to advise customers to buy original screens, the price differences between the originals and the copies could lead them to look around, and choose the cheaper alternative anyway!

It is clear that the copies aren’t direct ‘copies’ of the original iPhone LCDs. They are closely compatible replacements that have been manufactured from scratch and may have varying differences in quality. Here are some of the quality issues customers may have to face:

One feature that differentiates an original from the copy is how the digitizer (touch sensor) is designed. In the case of an original, it is manufactured as part of the LCD itself. In the case of a copy, the digitizer is placed on the glass.

As mentioned earlier, while the bare LCDs are manufactured by a few, several other companies purchase these and assemble them along with the other spare parts to make them functioning screens. The quality of the spare parts used determines the ultimate quality of the screen.

So, even if you could purchase an LCD from the best “copy” manufacturer,  the digitizer/touch (as part of the separately-manufactured glass) might have been sourced from non-dependable sources!

For instance, with the iPhone 6S and 6S+, Apple moved the chips responsible for touch processing onto the LCD itself. The ‘copy’ screen will end up having ‘copy’ chips too!

Additionally, if you drop an Apple original, the glass often breaks, but if the LCD itself is unharmed, you can continue to use it until the glass is fixed. This is usually how Mobile Repair Stores and Aftermarket Suppliers refurbish original parts with aftermarket glass. As for the copies, since the digitizer is on the glass, it stops working when it breaks. In fact, the LCD itself is more likely to break due to the thinner and more fragile glass.

The LCD panels may have poor image quality, as mentioned earlier. They could have issues in brightness and contrast, a more ‘coarse’ look as compared to the original, and a reduced refresh rate.

There will always be a telling difference between the performance specifications of an original and a copy. For instance, in the case of a copy, the battery can get drained more quickly and mess with the operating system which was meant for the original screen design. Your backlight could get damaged too!

With the 6S, 6S+, 7 and 7+, the home button- part of the 3D touch- is part of the screen assembly. A lot of times, the home button flexes on copies don’t work properly and stop the touch ID from working.

There are issues with the frame that holds the LCD in place - often, they just come off! This can cause damage to the flex cable, and the screen will need to be replaced.

Given the differences between the original and the Aftermarket copies, it might seem wrong to promote the sale of the latter. However, it is a fact that customers tend to choose the cheaper copies over the originals. Also, customers may have to wait longer to get original replacements as most Mobile Repair Stores don"t keep them in stock.

So, what is important is to get replacement screens that are as close as possible to the originals. As mentioned earlier in the article, some of the most popular brands available in the market are Tianma, IVO, BOE, etc.

KingWo claims to provide a close to perfect copy of the iPhone LCD, especially in terms of brightness and polarizer. Here are some of the features it offers:

The BOE screen is thicker than the original because of a plastic layer added to the phone glass lens. The assembly weight, the home button size, and the thickness of the whole screen and glass lens are higher than the original.

In terms of price, ShenChao and JDF are usually considered as the cheapest screens you can find on the market. For Middle of the pack in terms of quality with a competitive pricing TianMa and Longteng are good choices. For the highest quality on the market KingWo (Teevo) and AUO are your immediate go to choices.

At TechRepair, we provide iPhone LCD screens and digitizers that are individually tested and packed into premium boxes. These parts are tested when manufactured and certified by our team to ensure the highest quality standards.
