The men drop them on the floor, the women in the toilet bowl because the back pockets of pants too small,” sums up the technician of the smartphone repair counter of the sign We Fix. As for tablets , it is often their large screens that crack when you forget them on the sofas before sitting on them. Our electronic devices are unfortunately as fragile as they are essential. But it is useless to hope to play the guarantees of conformity, they do not apply to these situations.

Insurance and extension, do not count too much to repair your smartphone
Do not have much more hope of being covered by the extended warranty or the insurance you may have underwritten with the operator, your insurer or in the store. With a cost of between 100 and 140 € per year (on average 8 € / month for a phone and 12 € / month for a tablet), these contracts are riddled with exclusion clauses and play very rarely. In case of breakage, in particular, they most often submit the care to the “intervention of a third party”. The damage must therefore have been caused by the clumsiness of a person who is not a member of your family, and who agrees to write a letter acknowledging his responsibility. In addition, the deductible remaining at your expense is always high – from 200 to 400 €.

Repair online, shop, home … What to choose?
In general, you will have no choice but to have your smartphone repaired … at your expense. For this, you can contact the after-sales service of the manufacturer, or use one of the many solutions now available on the market: site sales of spare parts to repair yourself (, Tout- pour- ), specialized shops often established shopping malls (WeFix, Point Service Mobiles), mail repair site (Save my Smartphone, The Clinic smartphone), even interventions at home or at your workplace ( , ), you have the choice of the provider!

How to choose between repair and purchase?
First advice, study the quotes closely. According to the operations, independent service providers are two to four times cheaper than the after-sales service of major brands, and charge prices that are roughly comparable. Rather than trying to earn a few euros, choose the signs that best guarantee their intervention. Some are content with the legal minimum of three months, others opt for six months, but the majority carries this security to one year. For services that cost almost the same, it’s a real difference. Especially if you plan to resell your equipment. Note that if the repair estimate exceeds one third of the value of your smartphone on the second-hand market, the majority of sites and workshops will offer you its redemption in the state in exchange for an equivalent terminal reconditioned and therefore guaranteed. The difference to put from your pocket is often less than or equal to the price of the refurbishment, the operation is financially interesting. If you accept, they will take care of free transfer of your data (accounts, apps, files).

How much does it cost to have your smartphone repaired?
The replacement of a broken window on an iPhone 4 or 4s costs on average 60 €, 110 € on a 5 or 5s, 140 to 170 € for a 6 or 6s. A new Home button 60 €. On Samsung equivalents, the bill is heavier: 90 to 170 € on a Galaxy S4, 180 to 190 € for an S5 and 140 to 160 € for the recent S6. Price differences can be explained by the fact that on Korean smartphones, the glass is stuck to the touch screen. As a result, the workshops replace the complete sandwich (glass + slab) while a pane of iPhone fart change alone in the majority of cases (this is particularly the case if you still manage to activate your apps despite cracks). Logically, the replacement of the central button (“Home” button) costs him about the same price regardless of the make and model of terminal: from 40 to 60 €. As well as deoxidation, the last chance operation to bring back to life a smartphone that has fallen into the water. Count from 60 to 70 €.

Can I repair my smartphone myself?
Repairing oneself is technically possible thanks to tool kits and parts sold online. But it’s not always profitable … and sometimes delicate. No problem to change a battery on a Samsung, it disassembles in seconds without tools. As much as saving workshop costs. On an iPhone, the same operation requires buying the necessary tools to unscrew and unclip some fragile connectors. The workshops invoicing this operation 40 € on average, as much the entrust to them. Replacing a screen yourself is much more profitable. For a Samsung Galaxy S5, the glass and the ad hoc tools cost twice as much as the service outsourced to a pro: 90 € against 180 to 190 € (parts on,, Piece-Mobile. com,,, etc.). Free tutorials are available online. Take care to dispose of any static electricity that has a devastating effect on electronic components by wearing cotton clothing. Operate on an insulating work surface (plastic, wood), with the plastic tools provided.

Smartphone down, I check my warranties.
A touch screen that responds badly, a bad contact, a faulty button … If your smartphoneor tablet is a victim of a malfunction within 6 months of purchase, exercise the guarantee of conformity, by contacting the seller. If the fault is not due to improper handling, it must be repaired, replaced or refunded. This warranty applies within two years of the purchase, but after six months you will have to prove the defect, whereas before the malfunction is considered to have existed at the origin. Good news: as of March 18, this warranty will cover two years after the purchase. Beyond that, you may have a commercial guarantee, sometimes up to three years. But the content is set freely by the seller, and exclusions are numerous.

Damages, especially the screen, most of the time it’s the screen that releases us first (69%), then the battery (15%), finally the buttons, shells, wifi and operating system (16% ) and unfortunately 77% of breakdowns are not covered by a guarantee.Consumer choice
Although 71% of consumers use a repairer, 21% repair themselves and a minority, 8% do not repair.

And you what do you think?
“I should have had it repaired”My girls broke the screen of their tablet offered at Christmas. The seller advised me to play the insurance for not paying the repair. Bad surprise, the tablet has been declared irreparable. The insurance only refunded me 200 €. I had to add 250 € more to buy a new one. In summary, I would have done better to entrust the repair to a site for 130 €! Not to mention the photos and videos permanently lost.
Nadia, 34 years old
“I arrived there alone! ”
After a screen break on a Samsung Galaxy S4, the touch screen still working, I ordered online a screen glass with its tool kit and a new battery, for 60 €. I only had one problem: take off the broken glass. My hair dryer was not enough, I would have needed a more powerful stripper. After this moment of stress, I completed the operation in two hours.

What are the differences between LCD and AMOLED?
The slab of a screen is equipped with several elements. Among them, we find the liquid crystals that equip LCD screens. For PMOLED and AMOLED screens, the liquid crystals are replaced by organic light- emitting diodes . The main difference comes from the light source.

LCDs require a backlight (tubes or LEDs ) while for PMOLED and AMOLED, it is the diodes that produce their own light . AMOLED displays are active matrix OLED displays while PMOLEDs have a passive matrix. The PMOLED is reserved for devices that do not require a powerful display, because the power source does not allow to display very fast images. We find them on old MP3 players for example or even on the screen of the new Samsung Gear 360 . On our mobile devices, we find the AMOLED or the LCD.The advantage of the AMOLED operation is significant, without a bad word, since it saves the space occupied by the backlight system necessary for the LCD. This also allows to have flexible screens. AMOLED has many advantages over the LCD: better color rendition and virtually infinite contrast . Indeed, black is obtained by turning off the diode. While on the LCD, black can pull to gray because the backlight is always on. Thus, the AMOLED is more energy efficient than the LCD . The response time of the AMOLED is less than the LCD, of the order of <0.1 ms.

The LCD is an old display technology that has succeeded the CRT, the old cathode ray tubes. The LCD has existed since the early 1970s even though it was widely released later. Among the LCD panels, there are several technologies: TN and IPS mainly. TN was the most used technology, but it is the least qualitative. The IPS, S-IPS and FFS technologies are similar and can increase the viewing angles from year to year, all these technologies evolve, whether in terms of contrast, color fidelity or consumption. The FFS and S-IPS are often indicated on the data sheets as IPS slabs. In fact, only extensive testing really differentiates the technology used in the slab. Numerous technological advances have made the IPS competitive against the AMOLED in terms of price – quality ratio.

Borderless screens
This is a dream for most of us, to have a terminal equipped with a slab that would take up all the space, with no apparent edges and edges . But this is not possible in the immediate future for several reasons. Screens are currently composed of several layers that must be glued together. In these places, no display can be offered. Edges must also be present to hold the screen on the smartphone. Finally, the fragility of screens requires that they be protected by a border. But it is certain that we will arrive at the screens without any edge, the builders going in this direction and the obstacles not being insurmountable .

Electronic ink and sunscreens
Many screen technologies exist to allow our smartphones and other connected devices to have a longer battery life. This is for example the case of Wysips sunscreens developed by the French company Sunpartner Technologies . They will meet again in the next version of TAG Heuer’s smartphone, the Meridiist. It is actually a filter that sticks under the screen and allows photovoltaic cells to capture some of the light (artificial or natural) to recharge the battery of the smartphone. The filter passes 90% of the light emitted by the slab, which may affect the brightness and color rendering.
In a more affordable version, the Mobile World Congress 2014 was the scene of another demonstration, that of an entry-level Alcatel One Touch equipped with such a photovoltaic filter, with a view to democratization. Rather, it would be a smartphone for emerging markets and able to provide a secondary charge when no plug is at hand (its charging capacity is only 2.5 milliwatts / cm2 maximum) ).

The screens of the future: flexible or curved
The LG G Flex we tested has a curved screen. This is also the case of the Samsung Galaxy Round . This format is allowed through the use of an OLED plastic plate. The slab itself is flexible, but the rest of the phone is not, so the screen is only curved. Anandtech was able to test the screen outside the smartphone , which allowed to twist it in all directions while a video was projected.YouTube link Subscribe to FrAndroid  In the future, it seems likely that we have flexible smartphones. Samsung plans to offer this kind of terminal by 2017 and, meanwhile, sells smartphones “edge” since its Galaxy S6 . Apparently, the manufacturer has already demonstrated three functional and flexible products. A tablet that could bend to hold vertically, a screen that rolls completely and a smartphone folded in half, without hinge. The most interesting is perhaps the foldable electronic ink screens. This would read his newspaper or book on a foldable screen and put it in his pocket to carry it!

Terms not to be confused
” LTPS vs. IPS; IGZO vs AMOLED; LCD vs IPS; Super AMOLED vs. AMOLED “are queries that often come back to FrAndroid, but ultimately do not want to say anything. Indeed, if the IPS is a family of LCD screen in the TN image, LTPS and IGZO technologies refer to the method of manufacturing LCD panels.
In contrast, the AMOLED slabs are a family of display technologies that compete directly with the LCD slabs and all their variations (TN, IPS, MVA, etc.). Finally, Super AMOLED is the technology used by Samsung for its AMOLED slabs and therefore refers to the matrix used (PenTile).
