A few buttons on face not working...

Besides dropping my phone a few too many times, I recently got my phone a little wet (on scale of 1 to 10, 10 being submerged, I would say this water contact was 3).
After letting the phone dry overnight and performing a soft reset , I now have lost the use of the left button on face (Above TALK button)and the multi button( a good name for this button escapes me).
So I tried a hard reset and the HTC ROM upgrade hoping some magic would fix this button. No magic. Any ideas?

Probably should have let your phone dry out a bit longer. Putting it in the oven on it's lowest setting for a few hours works too, if you happen to ever do it again, but I guess that isn't going to help you right now. If that's the only function you lost then I would concider myself lucky, especially since you can use the bottom task bar button to do what you would use that button for most of the time anyway.

sweet jesus, this is horrible :O
good luck with your device...

Remove the battery and sim card. Look at the horizontal strip where the sim card goes... the strip should be white. If it isn't, then the water has damaged your device. A continued "drying out" may restore the circuits.

S100 keeps hard reseting

Hi,
My S100 keeps hard reseting. It was working ok, until last week. Since then, it has hard reset 3 times now.
It happens randomly. I've formatted the SD card as well, in case the issue was card related. I don't know what to do...
R 1.12.00
G 1337.42
D 1.12.120 WWE

Could it have anything to do with my backup battery?
I've noticed that I have no issues if it's connected to the power, but if my battery gets to half capacity, it's when my problems begin...
ALL help is welcome....

Hi got same problem ...unfortunately while using tomtom so i lose myself somewhere in between Austria,Switzerland and Germany....
so it reset many times even while phisically resetted...it didn't start any more for 10 min and then it starts properly...and again and again.....
noticed low internal battery....will change it (if i found the user manual) and i'll let You know the progress...

....small reply...i check in the User Manual but no idea on how to change and which is the internal backup battery....any suggestion ? ? ?...pls ?

up.........thnks

uh...well i have the same problem and i know why it happens...
It's just that the back cover has a small plastic notch at the bottom right side which must touch and push a small switch located at the bottom right (the switch is located just above the red plastic thing).
Since my back cover has a side plastic notch that is broken, sometimes the back cover gets a little bit loose, forcing the bottom switch notch to release that switch which in turn forces the ppc to sometimes reboot/hard reset.
Check if your back cover is Okey.

WOAH...got it....(i'll keep testing tomorrw while running somewhere in France....) is enough to force it with a ...."piece-of-something" placed there in case? or there are some other indications on "how to"??.....
say thanks anyway is always not enought......

yes...you can use whatever you like...(you can even glue it)
Honestely i don't know what was HTCs ideia of putting that dumb switch in there...
Regards,

Yeah, that switch is pretty dumb and a waste of money. None of my newer HTC phones have that switch. I guess in more recent phones they realized it was a waste.

The switch was there for a good reason
Hi! The switch is there to turn off the phone when you open the battery cover. Remember, WM 2003 is based on volatile memory, so if the power goes out, all of your data gets deleted and the OS has to reload from flash rom. Anyway, to my understanding the switch has to do with not using the backup battery without the actual battery in there as the backup battery is strong enough to power the volatile memory but not the entire device. The solution I chose for my device is a piece of clear plastic tape running along the crack between the battery door and the camera housing. I attached the tape to the sides as well, and made sure to use the stylus to push the tape down between the grooves on the sides. Otherwise dust would get in right away and weaken the bond blah blah blah.
Summary: Tape on the battery cover, the switch was a good thing. All devices since MDA Compact run WM5, which is non-volatile memory based and is always stored no matter what.

Hi guys,
At first I decided to open up my Magician, to look for that "backup" battery.
Didn't find any.
Turns out, my hard reset problem is caused by my phone battery. The regular battery is wasted. So wasted that the phone cant hold the backup. I found it weird that the phone wouldn't hard reset if was kept on power. As soon as i unplugged it, it went bye bye.
I managed to test it with a battery from a friend, and as soon as he used my battery on his phone, the backup warning come up.
I don't wanna say that, in some cases, the back lid won't cause this problem.
In my case, thankfully I managed to sort out where the problem was.
Thanks!

It keeps hard resetting
Hi Guys,
i've tried all the above written tips and tricks; but, my magician still have the same problem, every time i removes my battery it goes hard reset and again i've to start from the scratch - align screen - then it installs the applications again and back to the square one.
previously it was ok and after a year and half of using it started going soft reset now and then itself - i gave it to a local services center, they said that it has a loose contact to the battery that's why it gets soft reset, so i got my battery connector replaced. it solved the soft reset problem, but now the bigger problem has come up - it goes hard reset every time i remove my battery.
one thing i've noticed - it never hard resets when i keep it connected with my charger or usb cable
any one has any idea why its happening...

well i would suggest that your backup battery is dead...
Keeper

that i've checked keeper it always shows 100%.
and all the time since i bought this i've never seen that thing moving from 100%,
ok just tell me is it possible to replace the backup battery?

Well, i doubt it...all this stuff is really small...honestely i don't even know where is the backup located at, in the pcb... (photo of the pcb is in here: http://forum.xda-developers.com/files/naked-magician-insane.jpg)
I would suggest that you should go to a repair center and ask them for a repair cost budget...that way you'll be informed what exactly is wrong with your pda...
Keeper

webshocker, if you want to try and replace your backup battery, check the photo in attachment that i've made...
It seems that it ain't that hard to replace it...
Regards,
Keeper

Screen problem

I am sure someone has the answer for this.
The "touch" part of my touchscreen has become less responsive. I have to bare down in order to get the screen to accept touch inputs. Anyone know how to adjust this?
Thanks

It really seems like there should be a registry edit for this like there is on the touch pro, does anyone know what it is?

I cant seem to find the posts I was looking for, but it seems that the titan was hardware limited when it came to changing screen sensitivity. I remember it being discussed in old threads but none of the registry mods, i.e. adding reg keys or changing reg keys did anything.
I could very well be wrong as this is speculation until I find those posts I remember reading a long time ago. I will keep looking too...

I appreciate it.
I wonder what I could do then to regain the functionality. It was working just fine until about 3 weeks ago and it now requires a much firmer touch.

Align, Soft Reset, Hard Reset, Connections, Replace Screen?
I doubt this will help but just some thoughts. I don't suppose any of these may help but they are simple enough, well not so much the hard reset if you don't have a good backup solution.
Try going Start > Settings > System > Screen > Align Screen and tapping lightly to calibrate screen for lighter input.
Try a soft reset.
Backup you data and programs and try a hard reset.
Open up your case and check the connections and mounting of the screen. You just need a some small flat head screw drivers, a clean surface. A small plastic guitar pic helps for separating the case. Tweezers help if you have relative large hands. You could even just swap in a new screen. You may want to buy some of that special tape to hold a new screen in.
Here is a cab with my screen calibration just in case it helps.

Do you have anything that adds functionality to touches such as FTouchFloSL installed? Those can occasionally have unintended consequences. Try disabling or uninstalling them.

I have soft reset, hard reset, even installed a new rom. Every time I did the above I had to calibrate the screen, which is very, very, very difficult being that I have to bare down so hard.
Since I have a TP now I may try taking it apart. If I need to replace the screen, does anyone know where I could get one?

nothing special installed, but I have had them in the past.

I have had sensitivity issues with my titan ever since I have owned it. I had a spot in the screencenter of the top half that would take several seconds of holding the stylus on it to get an input.
I have tried to recalibrate several hundred times with very light touches, and it never seemed to help a bit. hard resets didn't help at all either. God forbid putting a screen protector on it, as it would render it useless.
I recently found a replacement "Touch screen digitizer" on eBay for less than $20, compared to $60+ for a replacement lcd and touch screen assembly. I was rather nervous about disassembling the touchscreen assembly, although I have taken the screen out of my phone a few times to try and find a secret gremlin causing the trouble. All in all, a razor blade to cut through the adhesive and taking the metal casing off the LCD to get at the very small connector for the touch panel was the most difficult part. It only took about a half hour and three beers of courage. Now it works better than ever before.
If you are electromechanically inept, I wouldn't suggest this fix, as it isn't just bolting in a new part. It does involve intricate work. There were a couple times I thought, "OH S%$#!" and I routinely take things like this apart. So try it at your own risk.

A possible final fix of back button I FOUND~

Guys I did some search job today and have a possible final solution to the back button problem.
Luckily this is also in the forum posted by user ID:insaneturbo13
his thread is here:
http://forum.xda-developers.com/showthread.php?t=833663
He is a Samsung Captivate user, right. Since I think if nexus s have met with is annoying problem, other samsung phones may either. So I did some search job in bed with my insensitive-back-button Nexus S, and found the Epic 4G, Samsung Focus, Captivate, etc. Almost all samsung phones got users annoyed by the problem.
Then I searched the Youtube to see if there is any Samsung user had ever achieved some success in solving the issue, and I found.(You won't know how terrible it is when you have to use a U.S VPN just to watch Youtube since it is blocked in here China mainland... really slow speed...together with facebook and twitter...ToT)
My understanding to the cause is: The picture of the back button is a thin line with an arrow, so the inside paint here may over-cover this thin line, which will definitely make the touch action less sensitive. And that's why there are less people got such problem with the other three keys.
And since capacitive buttons actually respond with the obvious temperature difference, so many frustrated nexus s users like me found under warmer environment the problem is less annoying...
Maybe this is only workable for insensitive problem. But hopefully this is a way.
Since I am a Chinese, it's impossible for me to have an exchange with the Bestbuy. So this is my only solution. But for most of you, it's highly recommended to take several exchanges before you definitely want to try this way.
Of course, try this at your own risk

what i did was tighten up the screws on the back of the phone... especially in the lower part of the phone. I haven't seen the issue since and initially it was a pretty often issue for me.

I think this is also a good way to solve the problem especially when you dont have to take to phone apart~
The theory may be the same, which is to make the distance between your touch and the module inside shorter cuz there is a piece of rubber under the button position so it can be possible~~
Thanks for sharing this way Dude~~~

how did you access the screws at the bottom to tighten them?

Take off the battery cover. You have 6 bright screws around the edges of the phone. Tighten those up.
Sent from my Nexus S using XDA App

Although, I know this is not gonna help, but it comes from personal experience.
In the beginning, I used to be haunted by the silly back button "bizarre".
I factory reset the phone then voila. It's gone.
The reason I am confident to post this is, my brother's phone was fixed in
a same way as well. I know, I can be just lucky, but I just wanted to share.

thanks, I decided to watch the video on how to take apart the phone this morning, didn't do it, but it covered the screw access for the hidden 2 screws.
tightened the screws what little bit I could without fear of breaking something (they were already pretty tight), but it made no noticable difference.
I actually got my phone a few days before they were launched (friend is at&t store manager), so I 've been living with it as long as they have been available. it's annoying, and did get a little better with froyo, but not bad enough for me to tear apart the phone and risk damage to the screen...

there are no hidden or covered screws and the phone doesn't need to be taken apart.
look here: http://guide-images.ifixit.net/igi/BJtxWYS4NMaMyMKL.medium
these are the 6 screws

Mine just started this thing where it presses the back button by itself. Pretty anoying and is making the phone useless. I can't do anything without it just hammering on the back button.

hi everyone,
i'm new to this forum, and joined to see if anyone has been successful in fixing the back button issue...
i've followed some of the advice from previous posts (tightening screws, reset factory settings, updating the OS) but still no luck.
hoping that someone might have discovered a fix (apart from returing the device!) they could share.
thanks!
-----------------------------------------------------------------------------------------------------------
hi everyone,
After posting the thread above, I updated OS to 2.3.3 and now back button is working fine.... I waited for a couple of weeks before confirming this, so hopefully anyone still waiting on a fix could try what I did. This seems to be a software problem more than anything else...
btw - 2.3.3 noticeably washes out colours, and there's a yellow/green tinge to white space. awful.

Hi
I did the same and the problem has gone - just realised after reading your post that factory reset solved this problem.

My phone is constantly on 3G but whenever it dips into Edge or has a weak data signal I notice the back button issue as well. And I tried a factory reset but it did
not fix the problem on 2.3.3

Back button issue
There are a few longer threads in this forum about the back button issue on the Nexus S -- for some people the back button doesn't work at all, and for others it turns on all by itself. There were a few replies from a Google employee (ryguy) who said it would be fixed in an upcoming OTA update, etc. but some reported having problems AFTER getting 2.3.2 when the problem didn't exist before. There are also other reports of tightening the screws on the back of the phone, which haven't tried but seemed to improve things for people whose back button WASN'T working at all.
For my phone around 2-3 weeks after buying it I had the back button come on all by itself. I fixed it by doing hard resets, as suggested on an earlier thread that deals with this issue (it's like 10 pages long but has the complete story of everyone's experience and fixes with this issue). Anyway, the point is for me after the first hard reset the problem persisted, so I did it a few more times (like maybe 5 times) and now it's gone.
There are some people who tried a hard reset (factory settings restore) and the problem still persists but I think that you have to do as many hard resets as possible (like, over and over and over) until the problem disappears. I'm rooted so I did a Nandroid backup first, then did 5 hard resets through Clockwork Recovery (select the "Wipe User Data" option), and after five hard resets I just flashed by backup and I was back to where I was, minus the back button issue. You don't have to be rooted, of course, to do this, but if you are, doing that ROM Manager backup allows you to quickly reinstall everything to the exact way it was after you're done with the five or 10 hard resets or whatever.
If you're unrooted you can power off the phone, then turn it on while holding the Up Volume button. This boots you into Bootloader mode and you can navigate around to do a factory reset. Or, if you are rooted and have ROM manager, you can use ClockworkMod Recovery like I did (see other threads on how to use these programs).
Anyway, again for me I had to do a bunch of these hard resets to fix the problem, so if it persists after the first two resets, I think you have to keep doing it until it disappears. Hope this helps - TC

i think mine is forever beat. 15 hard resets and its still there.

My apologies for bumping such an old thread... But i got a captivate to serve as a backup phone, and i slapped over ICS on to it..
Everything was super awesome.... BUT! not the Back button.
A few minutes of google'ing later, im here.
So after reading through this thread, and the one linked to in the OP, i opened up my Phone and ....well....went on with it.
50 Minutes later :

Some Tips :
1: Once your down to the frame with the LCD assembly stuck to it, first remove the Antenna Module. Under that disconnect the black ribbon connector. (This ribbon connects the capacitive button module to the main board).
2: Before starting to Pry apart the LCD from the frame, take a hair dryer and heat up the edges of the LCD Assembly's frame. This helps a freaking lot in prying it apart. Plus it somewhat preserves the 3M adhesive tape present underneath, and can easily be reused.
3: Start prying open the LCD, from the Ear piece side. Take your time and DO NOT!! And i freaking mean, DO NOT!!!!! rush through while removing the LCD assembly.
4: When your almost half way through (or slightly more , but significantly above the capacitive buttons) take a peak between the frame and the LCD assembly, youll see the "Bridging/Connecting" ribbon i mentioned earlier and it might be stuck to the LCD's back.
-> the best way to proceed further is to simultaneously heat up the "glued" parts and slowly continue with removing the LCD. This way, the glue will not stick to the whatever parts it is meant to stick to , THAT strongly and will be much easier to remove.
5: Now as soon as you reach the part where you can see the Capacitive button module sticking to the LCD assembly, go into SUPER FREAKING SLOW mode... THE RIBBON UNDERNEATH IS VERY VERY FRAGILE! ONE YANK AND YOU'LL HAVE TO PURCHASE A NEW CAPACITIVE MODULE.
*Best way to do this is, to again simultaneously heat the concerned parts while slowing pulling the LCD assembly and the capacitive button module apart.*
You can try going LEFT-RIGHT-LEFT-RIGHT alternatively, to slowly make the adhesive give away.
6: After you have the LCD assembly out, its pretty much dependent on how stable yours hands are at slowly etching out the Light gray parts.
-> You can hold the LCD assembly against a TABLE LAMP / some light source, to better see which parts of paint you need to etch out. *i Almost etched the whole of my back button* So be very careful and gentle as well PATIENT!
Before assembling the LCD back into the frame, i took a small piece of paper (about the size of the capacitive button module) and stuck it between the frame and the module. Just so that it makes better contact with the LCD assembly.
7: Stick the LCD back onto the frame and again heat up the edges. Also while putting the LCD back together, make sure the adhesive tape has not lumped up on any of the edges (This might have happened while trying to pry the LCD out) , if it has, then just gently even/flatten it out. Stick the LCD back and heat the edges. Rest, just take a soft cloth and squeeze the LCD's edges and frame together,so as to make sure they stick together properly. The heat really helps in bonding things here.
Assemble back the phone, blah blah.
I used a CREDIT CARD to start prying the LCD away from the frame. It was pretty easy, because of the heat.
DO THIS AT YOUR OWN RISK! I AM NOT RESPONSIBLE IF YOU SOMEHOW MANGE TO MESS UP YOUR PHONE! Specifically the LCD and the CAPACITVE TOUCH MODULE!
Big thanks to the OP for posting this.

[Q] Is there a RESET button?

Hello all,
Here's a quick question: is there a RESET button on the Hisense Sero 7 Pro...?
I'm asking because I recently purchased one from eBay, and it doesn't seem to have one. And, by what could be a remarkable coincidence, the device won't power up, just sits at the opening screen.
The seller says that it worked fine up until he downloaded something from a third-party site, then it wouldn't start up. However, just where the RESET button pinhole is located, the metal frame next to the screen has been pried back; and after my careful disassembly, I can't see anything more that a small metal disk attached to the motherboard. There's no obvious button (like there is on the Lite version) that would function as a RESET switch.
Conclusion: a user tried to activate the RESET switch...and when it didn't work, that individual tried to access the "innards" trying to see what was up. (There are "grooves" indented into the small disk where it looks like someone tried to access the pinhole with something like a bent paper clip, to no avail.)
(Sorry there are no pictures to show for any of this...except for the denting of the metal disk, it doesn't look any different than any existing pictures I've seen.)
is there something I'm missing? Is there something on the back case, perhaps, that I'm not seeing?
I've got another motherboard on its way...but it would be a very good thing if I knew for certain that the original one could be bad, and if there really IS/ISN'T a RESET button.
Thanks in advance for any help you might be able to provide!

And the answer IS....

I'll just answer my own question, if I may.
I just received the Sero 7 Pro motherboard I ordered...and no, there is no RESET button.
The tech from Hisense that I spoke with last week told me that there was--"I have a Sero 7 Pro here with me and I'm pushing on the RESET button now."
Uhhh, no. What you are REALLY pushing on is the back end of the little rubber piece that fits over the small metal disk I described earlier...which does nothing. (Go ahead and try it. See? Nothing.)
So the motherboard has some sort of issue. Strange thing is, after I got the new one, installed it and it powered up okay, just out of curiosity I reinstalled the first one...and it also seemed to work just fine. (I don't trust it, though.)
So there's your answer: no, there is no RESET button on the side of the Hisense Sero 7 Pro.
