Hi,
since people are saying no android phone is build like an iphone (with no any knowledge in electronic), I like to find the quality of the electronic inside.
Everything, if its possible , such as capacitor, transistor, resistor, chips, board, connectors, etc.
I'm pretty sure that I found a list for the iphone VS some android phone, but I CANT find it anymore.
Some one can help me with this? tks

Hello! I've never poster here before and honestly I haven't been able to do a thorough search of the forums yet... because my internet is atrocious! You see, I live in the woods and have super bad reception and while I fully intend on buying one of those wilson booster thingys I thought I'd take this opportunity to tear my phone apart. my goal? to find the built in antenna and attach a dongle that would clumsily poke out the side of my brand new htc incredible so that I could just plug in a big ass external antenna. unfortunately phones have become so advanced and compact that I just couldn't find the antenna anywhere... I'm really hoping someone here knows exactly what a smartphone antenna looks like and where it is. I had a couple guesses... but asking is so much easier!
anyway, here are the pictures of the insides, the makeshift dongle thingy and photo of the phone reconstructed and working just fine (so not worried about bricking it ... so, where is that antenna!
update... i can't show you the pictures because apparently they are considered outside links and i am a first time poster. they are on my picasaweb of the same username.
Deleted, lack of help, already achieved.
General though I forgot to add if that project could be real, it would teach Samsung and att a great lesson and someone would sell these parts and make money out of them.
Sounds like it's more trouble than it's worth.
It's not like a car where you can unscrew a few screws and exchange the part for a new one. This device has thousands of microscopic soldered components, so unless you have very advanced technology, you are not going to replace core components.
I see something like this happening for laptops first.. and the reason they don't do it for them now (with very few exceptions) is because most everything is integrated into the mainboard.
Have you ever tried to solder an smd resistor onto a pcb with just your basic general use soldering iron? It's damn near impossible without putting too much heat on the resistor or soldering the pad next to it also.
Everything is so tiny and cramped in laptops, imagine how much more tight things get in a cell phone. There was one (or maybe a couple) mfgrs that are doing plug and play build a phone. Think hi tec Legos but in general. I gonna guess that the phone would have to be designed for this from the ground up.
Good thought.. but probably a few years ahead of its time.

Thanks for your insight. I was asking because I have done a lot of reverse engineering and a little 3D printing. I have seen couple of project Ara videos and it doesn't seem impossible.
I have a note 3 that I use for testing. I will play around with it and some other components. If I had any luck to start with, it would be a mini step forward
At best what you might find is some internal only interface like jtag or something that you can modify what's loaded on the eeprom and spi flash. Really big if on that.
It seems that I have either been too careless when changing my broken display, or I have a typical monday example from the production floor... Because the big flat cable connector mounted on the mainboard has cracked and a corner piece has broken off completely.
I managed to glue it back into place, but there's some plastic missing between the wired connection points. This means (seems to anyway) that my MicroSD slot is busted and is currently short circuiting the whole phone if any MicroSD is mounted.
Now my question:
Is there anyway to buy an entirely new one of these connector ports?
I've looked high and low online (eBay and otherwise), however I really don't know the proper terminology to search accurately.
I work in electronic manufacturing and we actually have connectors in stock, very similar to the one I need, but obviously similar doesn't cut it - I need the exact model used. If I had one I could easily solder it in place at work...
Does anyone have any ideas of how to find one?
I include one picture to clarify which connector I am talking about. It is not a pic of my actual mainboard, but a pic from eBay that I marked, just to give a general idea.
Hi Guys,
I was thinking to get a Android head unit, which are so expensive. then I heard about the thing we could do with the Raspberry Pi.
So is there any way that we could install Malaysk ROM on a Raspberry Pi 3 b+, and then then install the other hardwares( like GPS, rear camera)

"Malaysk rom" is not something you should aspire to, which is not in any way to suggest that it isn't hugely beneficial for those devices that it works on.
Here is the thing; the chinese car radios come with the worst software imaginable, and it is completely closed source -- even parts like the kernel for which they are legally obligated to provide source, they do not. So any improvement is a real pain in the butt to implement. So hacked system images are useful in that they can make it "less terrible", but there is nothing you can do to make a chinese radio "good".
Raspberry pi, however, can run Android that is built from source, which makes the whole "hacked chinese software" problem vanish entirely -- it is COMPLETELY REDUNDANT.
Of course, raspberry pi hardware is also just not up to the task of running anything that is at all intense. Its pretty terrible/weak hardware.
Now here is the thing... what you are thinking of is *not* going to be cheaper than a chinese car radio (which are actually very CHEAP, so its confusing when you start off by complaining that they're "so expensive" -- the reality is that the ONLY thing that the chinese radios have going for them is that they are DIRT CHEAP).
So first you need an SBC, ~$50 for a pi3 (or if you want something that is actually adequate for the task, $200 for a Dragonboard 820c or $250 for a Hikey 960),
Then you need a touchscreen, ~$100.
Then you need a radio, and since you aren't going to be printing your own circuit boards, that really limits you to leftover stock of DMHD-1000, so ~$100.
There you are, already at $250+, which is already more expensive than a chinese car radio, and you haven't added GPS, amplifier, ADC, control signals, or any of a whole heap of other things you will need.
And then at the end of the day, what you will end up having with that approach is a wiring rat's nest jammed into your dashboard, with connections that sporadically flake out on you. Its not a good approach.
Which really leaves you in a tough spot, doesn't it? Because on one hand, you have CHEAP chinese radios that really don't work, and on the other hand, you have an expensive rat's nest that sporadically doesn't work. In fact, I've put a lot of work into this problem, and intend to shortly begin selling a circuit board that will help with this problem; it is a mezzanine board for a Linaro 96boards SBC (such as the previously mentioned Dragonboard or Hikey), which takes care of sound (including amplifier), radio, clock, I/O, etc., etc, etc., in a way that avoids the whole rat's nest problem. But once again, the problem, for you, is going to be the price, because if you don't like the price of a CHEAP chinese radio, you are definitely not going to like the price of high quality.
Hi everyone, I basically have an ongoing project at the moment where I'd like to have a headunit in the open top kit car me and a friend are building. Everything is full on stripped down back to basics, no ABS, no powersteering but we're keen to have a bit of fimiliarities with the headunit. I'm struggling a little bit on exactly what to get, I don't know if an off the shelf solution exists or if I'd have to go down something like the rasperry pi route but effectively here's what I'm after from the unit. Don't mind the idea of a tablet of sorts as well, but it would need multiple USB slots (see below).
Android OS is probably best for what we're after however open to suggestions/other ideas
Multiple USB slots 3 minimum - 1 for ODB/ Diagnostic connection, 1 for Apple CarPlay and the other for DAB radio if required
Resistive touch screen - there's no roof on the kit car we'll do our best to weatherproof it but we'd like for the screen to be not effected by droplets of water if it does start raining
Something that's not incredible slow
The monitor and the OS can be two separate devices if required e.g Resistive monitor and then trailing a HDMI/USB to the computer which would be in a dry wiring tray.
Has anyone done this? Seen anything that'd suit? We're really open to suggestions and looking to find a solution asap.
Perhaps post in the Android head units forum, this thread is for specific "MTCD" units.
Most units I have seen are Capacitive screens not resistive, but rain does not affect either really when you dry them off.
If you are looking for reliable Apple CarPlay then Android head units are not the best bet.
I know that the Dasaita PX6 head units have a HDMI out which you can connect another touch screen to for dual touchscreens.
I have the Dasiata in a topless jeep which has had some (light) rain on it in the past with no ill effects.
Sorry all, new to the forums I'll post in the correct place now
