Disassemble the Htc One X Case

Disassemble the Htc One X Case

I have long wanted to write a similar article, but the opportunity presented itself only now. From time to time we have to repair Android devices. We do this as an exception at the request of friends or business partners.

The impetus for this text was the extreme stupidity with which manufacturers of Android devices place electronic components in the cases of manufactured gadgets. I, as a person who sees the insides of the iPhone and iPad every day at work, was extremely interested in the device of the products that HTC and Samsung produce. It is interesting to compare not only the characteristics of the devices, their capabilities, but also the potential of the departments that are involved in the design and layout of internal components and components of the manufactured devices.

I note in passing that I decided to write material based specifically on the results of the preparation of the phone, because if, for example, we take a tablet as a basis, then the design of the iPad in terms of thoughtfulness, efficient use of internal space and compact details leaves Samsung products far behind. HTC tablet solutions would not even dare to somehow compare, because they differ in design from the iPad in much the same way as a black and white TV with lamps differs in design from a modern LCD TV.

But back to our HTC One X. He came to us with a broken touchscreen. Rummaging through the Internet, they were surprised to find that no one was happy with the detailed preparation of this gadget. For example, on iFixit, there is no data on opening the HTC One X at all, and the guys with GTV disassembled the device only half.

It looks like HTC One X with the protective cover removed. Almost the entire top of the battery and half of the motherboard are covered by a copper film.

In the end, we had to arm ourselves with our experience and get to work. It would be logical to assume that in the process of disassembling any device, it would be most rational to resort to the dismantling of the elements and blocks that make up the device, gradually moving towards a node that requires replacement. But after seeing the inside of HTC One X after we removed the back cover, we realized that our hopes were futile.

The back cover of HTC One X. 1. Bluetooth antenna, 2. GPS antenna, 3. GSM antenna, 4. Wi-Fi antenna, 5. NFC antenna.

A mysterious place where the battery wires go.

The first group of loopback connectors that must be disconnected before removing the battery. 1. a loopback connector for volume buttons, a microphone and a vibrating alert. 2. LCD cable loop connector. 3. connector cable dock connector.

The second group of loop connectors that must be disconnected before removing the battery. 1. connector cable backlight buttons and polyphonic speaker, 2. cable connector touchscreen, 3. battery connector. The reason it was placed on the inside of the motherboard is a mystery to us.

When we saw what needs to be done in order to turn off the power, we were very surprised. It turned out that you just can’t take and disconnect the battery in HTC One X like this. Because the connector for its connection is located on the inside of the main board. And in order to dismantle the battery, you first need to remove the main board. I still do not understand why it could not be transferred to the outside in order to drastically simplify the procedure for replacing the battery for the same specialists of authorized HTC service centers.

In order to remove the battery in HTC One X, you need to do the following. First of all, you need to remove the back cover, on which are the polyphonic speaker, GSM / UMTC, NFC, Wi-Fi, Bluetooth and GPS antennas. The complexity of the design of the back cover is offset by the ease with which it can be removed. It’s good. Almost the entire area of ​​the battery and most of the main board are sealed with copper film. We need to peel off the part of it that covers the main board in order to free the battery. Then you need to unfasten the connector of the cable for the volume buttons and the microphone, the cable for the dock connector, the cable for the display, the cable for the polyphonic speaker and the backlight buttons, the coaxial cable of the GSM antenna and, finally, if possible (yes, because not everyone can do it) touchscreen loop.

Next, we arm ourselves with an industrial hairdryer and heat the battery so that it can be easily removed, because it is glued to a solid double-sided tape. This is done in order to weaken the adhesive properties of the adhesive tape, and it is relatively easy to separate the battery from the seat using a spatula. After the battery is peeled off we unscrew all the fixing bolts with which the main board is screwed to the base. Then carefully lift it and gently, using a plastic spatula, snap off the battery connector from the main board.

I am very curious to read the service documentation for HTC One X to understand whether it is really possible to disassemble a device whose elements are live? Or is there some other, faster and more efficient way to turn off the battery, which allows you to bypass all the operations that we did in order to turn off the battery.

For comparison. In the iPhone 4S, with which the HTC One X is quite comparable, the battery turns off quickly and easily. First, the back cover is removed, then the bolts that unscrew the cap securing the battery contacts are unscrewed, then its connector is snapped off and, finally, after heating, in order to weaken the action of the adhesive tape to which the battery is glued, the battery is removed using a special tongue.

It’s sad. HTC still uses wires in the design of its smartphones. Apple abandoned this practice in 2008 (with the discontinuation of the first-generation iPhone).

Returning to HTC One X, I’ll say that after disconnecting the battery completely disassembling the phone was quite simple. The only difficulty is the dismantling of the LCD display / touchscreen assembly, which is already very thoroughly glued to the bearing part, the frame. If it had not been broken, it would not have been possible to separate it without damage. Therefore, here we agree with colleagues from GTV that the display module is non-separable.

Disassembled HTC One X: 1. back cover, 2. LCD with a touchscreen, 3. the base on which the assembly with the display and touchscreen, the main board, battery and loops are mounted, 4. proximity sensor cable, 5. button backlight cable under the display, 6. cable for the connector dock, 7. the main board, 8. cable for the volume buttons, microphone and vibration alert, 9. battery, 10. SIM holder.

All in all, the HTC One X has been successfully repaired. During the repair process, not a single detail was damaged. Separately, I would like to draw attention to the fact that the cables present in the device are very fragile in appearance. Therefore, when working with them, great care should be taken.

During the anatomy of the HTC One X, a few thoughts came to mind. Of course, I do not pretend to be infallible, but still. First one. If we compare the design of the One X and iPhone 4S components, we can conclude how the R worksD divisions of HTC and Apple. And the illustrations are rather eloquent about how complicated and non-trivial the repair process for HTC One X is, and how much easier is the same operation with the iPhone 4S. I do not presume to say for sure, but I think that this affects the price of service. In addition, you can see that a non-collapsible iPhone (according to Apple service documentation) is more maintainable than a collapsible HTC One X.

The second one. There is a suspicion that HTC produces sophisticated devices with large diagonals not because it is cool and fashionable. Perhaps they just don’t know how to fit comparable smartphones into a more compact body.

The third. It flows from the second. Less compact elements, bulky design of nodes and irrational placement of elements inside the case eat up a precious place at the most important thing. the battery. The more compact the inside, the larger the battery can be placed inside the case. HTC with efficient use of the internal space in the case has obvious problems.

Now I leave HTC alone. I do not think that in the future the design of the company’s devices will change in a qualitative way. RD is not cheap, but HTC has bad money right now. I hope that in the future, Samsung will join Samsung in terms of using, searching and implementing some elegant solutions in the design of phones. Koreans have every chance to seriously compete for first place in the technological race and it is strange that so far they have not taken serious steps in this direction. While under the hood of their devices the same mess as in HTC products. I hope that in the near future everything will change radically.
