Can't remove back cover!!

I've been using my Touch Diamond for a couple of days now, and just read about the lens protector that apparently needs to be removed in order to take decent pictures.
Now I find, that it is impossible for me to remove the back cover!! I tried all sort of ways of pressing and sliding, but now I'm afraid to damage the device by using too much force...
Have any of you guys have similar problems?
Does have something to do with the heat build-up from the battery the expands the plastic cover?

Clean the back side so you have friction, and push UP. Should work. Just did it

That worked! You are GOLD, thanks.

Or you could throw it really hard towards the floor. Should also work...
I'm sorry, I couldn't resist

this has to be one of toughest problems ever to be resolved here!

a hammer would have helped...

I find taking the stylus out and pushing from that corner the easiest way. Its a bit of a pain to get off if you have greasy hands!!

this sounds disgusting. it sounds like his phone is submersed in oil and he needs to wash it to remove the cover =\
i also heard if you rub the diamond against your head several times then place it against a wall...it will stick..like a balloon.
now you try =\

Dude, WTF, you're a puss. You couldnt get the back cover on the phone open?

Clicky-clicky!
As you know by now, I managed to get the back cover off (...), but now I'm anoyed by a clicky-clicky unstability on the back - along the right side just above where it says "HTC innovation". It seems there too much room (or something) just under that spot.
Anyone else experiencing this?

My Diamond has a very solid feel, so I'm afraid I can't help you there. Just to make sure: are you certain the back cover is well inserted?

Trust me, I have (tried to make sure that it's properly inserted). I'm now considering sticking some aluminum foil in there - as this should also act as a heat sink (I'm also experiencing intense heat from the processor when WiFi is turned on for more than 5 minutes).
Maybe then the foil will also fill out that extra space, I don't know.
In general, I think that the back cover is VERY poor quality and really needs to be redone/redesigned. The diamond shapes on the back is a mess, as the device rocks back and forth when you have it on a completely flat surface (like a table) and operate the screen/buttons. It should be made with a completely flush back and a more sturdy plastic material (thicker, at least). Don't you think?

Probably a bad idea. Sure aluminium might transfer heat well, but it also transfers electricity very well.
If yours is asloose as you say there's the risk of it moving and making Sony-style exploding battery fireworks.

What if the foil just sits in the bottom part and doesn't come into contact with the battery? Does that still present a risk?

I don't have a Diamond yet to answer that properly. It was just a general warning about putting metal foil in electronics. If you can see ANY way for it to move from where you put it to any other component or connector - don't do it. And that includes small parts of foil that may flake off from rubbing when the case moves (which is exactly what you're trying to stop, soit's potentially an issue).
I'd not risk it myself, but you probably wouldn't die. Probably. Much.

By the way, I tested the aluminum foil, and it worked well to remove the clicky-clicky sensation/sound, but I quickly removed it again after reading the warning above.
Can anyone suggest an alternative material to fill the gap?

Yes on two different Diamonds, poor design, or design flaw.

Clicky-clicky has gone bye-bye!
I found another solution:
Cut a business card (not too thick) in half and place it over the battery on the inside of the back cover. Slide the back cover back on. No more clicky-clicky!

Today i spent what seemed like an hour attempting to remove the battery cover on my touch pro and FINALLY did it! I wonder why HTC made it so difficult. To fix the creaking problem, i just put some strips of tape on my battery cover and that stopped the problem

Seriously this phone is pushing my patience...

my phone has been giving me problems for the last few months now non stop. first that red light crap on the power button...now this....
My phones screen gets all distorted in Landscape mode. if i flip open my keyboard, it gets all scrappy, then i have to pop out the battery and restart in portrait...it runs fne until i flip the keyboayd out. freezes up and all that crap starts...why is this happening? how do i fix this? ive had the phone for 7-8 months not sure...but WTF man its still not even 1 year old....talk to me somoene is this just a piece of junk i bought? is there a fix? anyone else have this problem? ARRRGGGHHH!!!!!

what ROM are you using?
you should make a backup and then try a hardreset

If hard reset or new ROM flash will not fix your problem, then it is the flex cable that is at fault. I recommend replacement and had it done for my customers. Cheaper, albeit a temporary solution is to attach a thin sticky tape cut to shape to the flex. If you have no idea what I am talking about, then it is the job better left to professionals.

as enigma1nz stated, its the flex cable... i too had this problem, but i didnt buy a new one...
what happen is the sliding wears off the black coating on the wires and expose them to the interior parts, its like rubbing the two jumper cables together, it will spark...
what i did was cover the silver part with sticky tape, that solved the trick

I have owned my X1 for a year now, and yes it is now a piece of junk compared to other phones currently out.
Get a Dell Streak and be satisfied already!

It is not a problem affecting Xperia only, but rather something we call 'All slides disease', it affects all slide form factor phones due to vulnerability of the flex cable. It happens due to sheer act of someone using the phone as intended - sliding it up and down, answering calls in some phones, accessing the keypad etc. It does not mean Xperia is crap, just the downside of a particular form factor. Next one on the list of form factors requiring repairs are flips (clamshells). With a bar form factor very little can go wrong, apart from actual physical or water damage. With the advent of large-screened touch phones, as you can imagine, it's the screens that sustain the damage. Iphones are vulnerable in particular.

Water Damage Repair Help Nexus 6

Hello everyone
So a couple weeks ago I took a unexpected swim with my Nexus 6 in my pocket, and haven't gotten it to work since. When I got out I immediately took the phone out of my pocket and turned it off, only to have it boot back into fastboot a few seconds later, turn off, boot to fastboot, and turn of again. It did this several times till it just stayed off. I took it apart, dried it, and cleaned it in Isopropyl alcohol and tried to turn it on but got no response no matter what I did. :crying:
I would consider it fried except whenever I plug it into my charger, the charging icon comes up like normal and even does the battery filling up animation. I replaced the power/volume button strip inside the phone hoping that it was the only problem, but it still would't turn on. I haven't replaced the battery yet because the charging animation shows it's holding charge, but loosing 40ish% after a week and a half of sitting there.
So is there something else I can do, or is it fried? I'm probably going to get a new battery to see if that improves anything, but I honestly don't know what more to do. If anyone has any ideas, I'd love to hear them.
Thanks in advance!

It's fried. Best you can do is send to shop and see if they can salvage it.

Alright, I'll guess I'll have to do that. Thank you for your reply.

I would like to share photos of my phone and seee if anyone vcan help, my situation is kind of similar. I tried to charge after to days of silica drying and cleaning with IPA.
I thin the connection around the battery area isn't secure. Is there a glue that i could buy?

The only thing a shop may do, is give it a bath in a ultrasonic machine, and bake the board. Try a new battery, internal batteries never do well in WD.

How about sticking the charging coil to the new battery? What type of adhesive is needed?

You may still have enough adhesive left over on the coil to stick it to it. Otherwise it doesn't matter much, as long as its connected and not crazy loose, the frame will hold it in place.

I got it kind of working, but the sound is fuzzy and the screen is flickering a little.
I'm missing some screws, so I'll need to buy some new ones.
T3/M3 torx screws, 2mm/3mm height/diameter?

Galaxy S9 - green tinge screen, horizontal lines + flickering for months and now dead.

I posted this in the official Samsung forum but I get the feeling that nobody there has ever been inside a phone. Hopefully get better feedback here!
Going to provide a rundown of the phones history..
The screen started to go slightly green randomly about a year ago. But I noticed that turning the screen off and on again fixed it.
This issue became more and more frequent as time went on during a few months use.
Then it transitioned over to a permanent problem, with no amount of reboots or whatever to make a difference.
Then horizontal lines started to appear which would travel up and down the screen leaving the picture black in some parts.
Then I noticed another thing, turning the screens brightness down to about 20% removed the lines, and made the phone usable again (albeit still with a green tinge).
I thought that it must be a power issue rather than a screen issue, so changed the battery but sadly that didn't have any effect.
More months go by, and that 20% threshold got shorter and shorter until I had to keep it at around 10% brightness to get a full screen picture.
And now finally the phone seems to have died. It doesn't turn on anymore and there is no vibration so its definitely not just the screen being off.
FYI I couldn't see any signs of moisture and the moisture sticker hasn't tripped. But I still haven't ruled that out. I will examine further after getting some feedback..
I have of course tried all of the obvious like factory reset, clear cache partition and all that.
Before I open it up again I would like to know what people think?
Cheers!

Is the battery good? If the battery was really degraded though normally it wouldn't boot.
I wouldn't throw too much money at it especially when you can get a used N10+ for around $350 now. A substantial performance upgrade.

Hi thanks for your reply!
Yes I have swapped out the battery for a new one. The way it deteriorated felt like moisture corrosion but didn't see any signs of moisture inside when I looked. It could be deeper underneath the mainboard though as all I did was replace the battery so didn't see further than that.
Yeah I won't put much money into it, but I do have a decent understanding of electronics so I was hoping there would be a fix which I am able to do at home with basic tools to hand. Many things can be fixed with a reflow and individual pieces are cheaper to replace than say an entire mainboard. But I have no knowledge on this sort of problem so I'll wait to see if anyone else has and then open it up again and take pics of what I find.
Cheers!

Inspect the ribbon cable contacts for corrosion if you suspect moisture damage. Without a factory test jig finding say a solder fracture on a BGA chipset will be a lot harder. That's also another place corrosion from moisture damage can hide.
Generally with moisture corrosion damage will be evident on the buses and power supply section of the board.
If water damage is present the mobo is pretty much doomed because of the latent corrosion process. Water will also damage the AMOLED display pixels themselves if they're exposed.

Thanks for that. I suspect the screen escaped damage based on how it looked. All pixels were fine but those horizontal black lines would travel up and down so feels like maybe the controller or ribbon as you say because it felt like the screen was getting less and less power as time went by forcing me to keep lowering the brightness so that makes sense. Although it doesn't explain why it doesn't switch on anymore. Unless the phone is built not to switch on if the screen is disconnected?
cheers

Make sure the power button and contacts are good. Since AMOLED displays have an active matrix it could be that or the mobo.
Maybe someone recognizes those syptoms... thankfully I never experienced them.

Thanks for your attention and advice!
Sorry for the delay. I have had it back open and inspected every part closely for moisture damage. Couldn't see any signs but while I was there I changed the battery which sure enough fixed the power issue.
Strangely, the screen worked 10x better for about an hour after reassembly! Then it started to go back to the usual black lines engulfing most of it at the mid-range brightness level but not at low or high brightness which I find very odd. Last time I'm sure it did it at any brightness level over around 15-20%
Anyway better to just let you see for yourself. I have taken some videos and photos.
At this point I'm thinking it has to he solely the screen thats faulty as if it was any sort of power issue then it wouldn't behave this way..
This video was taken straight after reassembly.

The other was taken a few days later.

You're welcome. Did you inspect the display ribbon cable contacts? Someone who repairs these could probably tell by that vid. Probably the display, but I would try to verify that before you throw money at it. For $350-450 you could get a used N10+, a huge upgrade but no 3.5mm jack. Samsung leaves more off every year, too bad the price doesn't go down too. schmucks.

S6 Edge - problems after battery replacement (feels slow, gets warm, left touch button does not work)

Hi all,
I want to start giving the old smartphones that keep accumulating in our family a second life - which primarily means replacing aged batteries.
I actually want to use my S7 as a bike computer with the Komoot app, but decided to get some practice on my wife's old S6 Edge, which conveniently partially disassembled itself (bloated battery had opened the back cover).
So I got myself a spare battery and proceeded with the disassembly. Disconnecting all connectors, replacing the battery, reconnecting everything, and putting back the 13 screws that connect the frame to the display all worked ok, and the device would start up.
Alas, there are now a few glitches:
- the device feels quite slow (at least according to my wife... but maybe that is just subjective, now being used to much more modern devices)
- the device gets really warm (primarily on the middle of the right side, i.e. where the main board is located), even without any apps running, the battery also drains quite fast
- the left touch button (which on this device brings up the "task manager"/"app switcher") does not work. The right touch button ("back") works ok, as does the home button.
Everything else seems to work fine.
I disassembled everything twice, cleaned all connectors with alcohol, reassembled, same result. All connectors appear to be properly connected.
Any idea what could have gone wrong?
Needless to say, with that not-so-great result of my first repair attempts, I hesitate to work on anything more valuable than the S6...
Any hints welcome.
Regards
G

Welcome to XDA.
A connector pin may have been be damaged, inspect.
Do a factory reset and see what you got.
If that fails the mobo may have been damaged. Out of circuit they are suspectable to ESD damage. ESD protocols should be followed when doing repairs. At the very least raised the RH to 50% in the room.

It may not be your fault
The battery on my S7 swelled up a bit, so I got a new battery fitted, the shop had problems with the phone overheating so needed further testing. They had to replace the charging chip due to the battery swelling.

I was doing this on an ESD-safe matt, so that should be fine. Visually, the connectors are ok... but considering how small they are, I would probably need to check with a microscope (which I don't have... but I could try my macro lens.
There are two cable connectors with only two pins each (look a bit like mini koax connectors). The connect the charging board which also has the electronics for the touch buttons to the mobo. One appeared to have been squeezed, probably by the bloated battery. So I measured conductivity with a volt meter, they measured ok.
I guess I will write the device off... not worth to invest in more spare parts.
The S7, which I still like a lot , is a different thing. Would hate to break this, but the battery is nearly dead and might bloat anyway sooner or later. So on to the next test subject for my repair skills. ;-)

Wear a wrist strap and make sure the room isn't dry. Wear cotton clothes. Static electricity is omnipresent. Nonconductive plastics are can build up a charge, even paper. Keeping the relative humidity above 40% is very important; just boil some water in the room if needed.
2-3x stereo magnification Optivisor probably do it. Very handy for detailed work.
