Xiaomi shows that using toothpaste on cracked smartphone screen is actually harmful

There have been various tales of tricks or hacks that seemingly help smartphone users after their devices are damaged. A notable example of putting it in rice after it got submerged in water. However, Xiaomi has come out to disprove one such ancient myth. So let’s have a look.

The Chinese tech giant took to YouTube to share a video on the new Shorts format to disprove that the myth of using toothpaste to fix your scratch or cracked display. The old rumors used to claim that using toothpaste basically fills in the gaps in the screen and polish the convex part of the display to make it smooth and almost good as new again. But in the video, we can clearly see that there was no difference or improvement in the scratches in the smartphone that was tested on.

Rather, Xiaomi added that this age old tip actually does more harm than good. The company stated that the toothpaste is at times a polishing agent, however, the micro particles in the paste can not effectively repair the cracks in the screen. Furthermore, toothpaste is actually an alkaline substance, which might destroy the acidic resistance of the oleophobic coating on top of the smartphone’s display overtime. This layer is basically applied on smartphones display to help keep dust and fingerprint smudges away thanks to oils secreted by the human body. The brand also recommended that one should rather go to Xiaomi’s official customer care to deal with such problems.

Google Pixel 6 series screen cracking issue could be a manufacturing defect

The Google Pixel 6 series has been plagued with a number of issues since its launch. Now, the flagship lineup is suffering from another new problem, but this time, the issue lies with the display.

The news arrives from various Pixel owners that have shared their complaints on Reddit and the company’s support forum (via AndroidPolice). Reportedly, owners of the Search Engine giant’s Pixel 6 series have found that cracks have appeared on the front glass of both the base and Pro models. This issue is not entirely new either as early reports are a couple of months old as well. With the Pixel 6 Pro featuring a curved display, it is apparently more prone to suffer from this odd issue.

Notably, both variants feature a Corning Gorilla Glass Victus on the front and back. So, its even more odd that the toughest glass for phones in the market is facing this problem. The cracks first begin appearing on either one of the sides or the corners of the Pixel 6 series’ display, and unfortunately, using a screen protector does not appear to help negate this issue or make it less likely at all. For those unaware, spontaneous screen issues are not unheard off and have been seen before as well.

Although, this usually implies that the smartphone is suffering from a slight manufacturing defect. To put things simply, the small defect can cause pressure to build up in the display that eventually cracks up and possibly even split apart. Significant variations in temperatures also tend to cause this issue as well. However, the exact reasoning for the cracks are still unknown, but thankfully, only a small number of devices are facing this problem at the moment. Google has acknowledged this issue and has confirmed that it is investigating it as well. So stay tuned for more updates.

Korean Firm Develops Self-Healing Material That Restores Cracks & Could Be On Future Phones

The advent of smartphones brought with it a great chance of cracked screen as a result of the large surface area which the display now occupies. This is even more complicated by the adoption of the full-screen design which sees the bezels getting reduced. Somewhere in the world right now, someone has just dropped his or her phone accidentally and the screen has shattered. But this may soon be a thing of the past as a team of Korean researchers have developed a new self-healing material dubbed “Elastomer,” which can restore dents and cracks within 30 minutes.

Ordinarily, an elastomer is a polymer with viscoelasticity (having both viscosity and elasticity) and very weak inter-molecular forces, generally having low Young’s modulus and high failure strain compared with other materials. The new material comes with double the highest level of existing tensile strength which means it is resistant to breaking under tension. This has been a problem with self-healing materials in the past. The Elastomer is also able to heal itself under room temperature and has a tensile strength good enough to make it commercially viable. The team also disclosed that the new material can be used as a protective layer on mobile devices and it automatically restore any outside cracks within 30 minutes.

This isn’t the first time we’re hearing of a self-healing material for smartphones. Late last year, a team of researchers from the University of Tokyo in Japan reportedly discovered one. Earlier in 2017, a self-healing material was discovered by chemists at the University of California at Riverside and the University of Colorado that could not only stitch itself back together within 24 hours but also it could stretch 50 times its original size. In August 2017, Motorola was granted a patent for a glass-like plastic polymer can restore on its own when cracked. However, the use of self-healing materials for phone screens may still be a long time from becoming a reality.
