HTC legend. Screen behave very strangely.
When you turn phone on its kind a OK, but in some time strange things happen.
Some parts of screen are unresponding. Or for example if you slide at the bottom of the screen it acts as if you pull status bar down.
Some times every touch tries to pull status bar down. But then again it will be normal.
Is that a hardware or software problem.
I tried hard reset too, didnt help. So is it screen itself then?
I would change it, but still not sure about it. Why its not bad all the time?
Thanks for all the help.
Search for TouchRecalibrate in Market maybe that helps.

hardware i'm afraid.
had the same problem after my phone got wet along with me in bat-****-crazy storm.
you don't need to replace the lcd, just the digitizer.
i picked one up off ebay for £10.
the replacement process is kinda scary in places - mainly prising the digitizer off the lcd.
if you're still under warranty and the damage wasn't obviously caused by yourself (that includes getting water inside the casing - the water residue gives it away unfortunately) i'd flash back to stock and rma it.
Well I thought it will be digitizer too.
Already ordered one. And yes, my missus dropped it in to a toilet after just 2 months since she bought it new. Just didn't had time to get to it till now. And warranty doesn't apply for this
She should have bough same like me - Defy
So dropped phone and screen went out. Replaced amoled and digitizer, device powered on and lit up home keys, but no display still. Replaced main board, in case video was out on board, but no joy. Any thoughts? No custom software or anything....
Maybe you didn't clip on the ribbon cables all the way. Or, just try pulling the battery and booting it again.
When I replace my screen, screen didn't work for first few boots.

I checked and checked, digitizer works, I can reboot and swipe unlock, adjust volume, but no screen. At this point I'm thinking bad LCD. Thoughts?
Thx for response and ideas though....
I bought a replacement but ut was a cheap fake, not an OEM screen. It went purple then black within 10 minutes. I got my money back (thank you PayPal) and made sure the next one was an OEM screen.
I hope you didn't spend too much on the repair parts. You can pick up a new Note for about $290 now.
So it looks like a small part of the top of my screen is dead, already tried everything and no luck, The draw line test shows about a 10% of the screen not working. I think this might be a hardware problem, but not sure.
If its the hardware, is it possible to only replace the Digitizer glass, without replacing the LCD screen?
Where can I buy the part (hopefully Original, I read that third party replacements are usually disappointing, because of quality.)? I tried searching in ebay and amazon and was only able to find for the HTC one X not the plus version.
Is it too hard to replace or i'm better saving for a new phone?
Do you mean the area where the status bar is? My HOX+ also doesn't recognize touches there. It happened suddenly 5 months ago when I was playing games . However, I used to it and it is not a big problem, I will give it to repair when I get on vacation .
I already made some researches on the internet and it is not an uncommon problem for touch screens. Yes, it is the digitizer's fault.

Exactly the same problem, upper part of the screen (all notification bar). I have an OCD and this tiny things bug me a lot. I guess now I need to find a digitizer to replace it, the problem is that on ebay and other sites there are not HOX+ available, all are for the HOX.
Is there any difference between HOX and HOX+ digitizers? I thought both got the same screen.
I'm not an expert so I won't fix it on my own, better send it back to service .
Btw. I've read one time that you can put a piece of paper between the bezel and grill to clean some mess up which could get inside the phone. I was wondered that I was able to slip the paper there, but it didn't work .

yes it will work, but you can't only change the digitizer, it's too hard glued together. I broke my LCD connector while replacing the screen although
I was really careful, so it's not as easy as everyone says.
Thx, i will keep that in mind.
Hi,
As mentioned above, there is a problem with my A5. When my tempered glass screen protector is fixed and when my phone is charging, my touch screen seemed to go haywire. I am holding my finger in one place but the phone detected that my finger is shaking, wildly. Besides shaking, my phone will stop sensing my finger even though it is held there.
I doubt it is the problem with my hardware because I have already changed the touch screen, charging port and the motherboard by sending it to the Samsung Service Centre. I believe the problem is due to the tempered glass (my previous tempered glass) because it was put onto another A5 and the same problem occured. Now, I have purchased another tempered glass from REMAX (picture below), and it seemed to cause the same problem again.
So now my questions are
1. Can I seek for another alternative such as Spigen's tempered glass screen protector or should I just use the normal screen protector?
2. Am I the only one facing this problem?
3. Is the problem really due to the tempered glass?
Oh by the way, my phone is running on official rom version 4.4.4.

Without getting into too much tech details i have a list of possible cause's
1. with having a additional screen cover in place and power connected your body+screenprotector create a capacitor, this is exactly how the screen registers touch , so without the screen protector in place this wont happen. I've seen this on a few Screen protectors that use certain types of conductive glue/bonding agent.
2. faulty charger or fake chargers often cause this behavior, try another charger or use USB on a laptop not plugged into mains power, if the problem is gone then plug in laptop's main power, if problem still gone then your issue is charger, if problem starts when pluging in the laptop's power then it's either ground loop or your screen protector acting as above.
3. faulty assembly when fitting screen, they didnty apply the copper back shield or the protective cloth that act's as a shield around the ribbon cables
before anyone shouts that samsung fixed it, I know and i can quote many a occasion a cell phone was not fixed right first time by the OEM
if you activate developers options and switch on show touches then repeat the test , does the display always show certain areas that register touch , if so it can also show where the bonding agent has a airgap, this adds to the capacitor effect.
finally try wearing shoes when touching the screen, if wearing shoes stops the problem get your house wiring checked.

thanks saxmydix, i used multiple chargers and it is still the same, i tried charging in another house in another area, still the same problem occured, so i doubt it is the problem with my charger.

hi darkspr1te,
thanks for ur response.
1. so it is entirely dependent on how the screen priotector/tempered glass is sticked to the screen?
2. sorry for not including the details on my charger in my post. i am currently using an official charger that i got when i purchased my previous samsung phone(S2 gt-i9100g). i tried using the A5 charger and the problem persists. will using a powerbank recreate the scenario of the unplugged laptop charging? if it is the same, the problem is still there even when my powerbank is unplugged. i do not have a laptop at home and it wouldnt be possible for me to get my hands on a laptop that i can use these few days. i tried charging my phone in another house (in another region which is like 20 kilometers away) and it is still the same. and my brother's samsung galaxy alpha do not have this problem while charging.
3. so u are saying that the problem might be due to oem? once again i apologize for not including this in the post. while i am at the samsung shop, the person in charge tried putting the tempered glass (which was fixed to my phone) onto another A5 which was there due to a boot loop problem, and it started to have the same problem. is it possible that all Samsung A5's assembly do not have the copper back shield or the protective cloth?
apparently nobody in the samsung shop knows how to deal with my problem because they have never seen it before. it took me quite some time to explain to each person who attempted to serve me and i only managed to show the problem to one of the personnel (which was the one who helped me fix my phone). i went back to the samsung shop 3 times in 2 days. in the 1st time, he changed the touch screen, in the second time, he changed the charging port and in the third time, he changed the motherboard.
as for the test, i turned on the pointer location and i keyed in *#7353#, and i selected TSP grid mode. that is how i checked the problem. and while i was there, the shaking only occurs at where my fingers are. i tried enabling the show touches option and the display do not register touches until i touched them.
i doubt it the the problem with my house wiring since it is the same with my other house but thanks for the suggestion. i will definitely try wearing shoes when i am at a different house. maybe both my house got wiring problem.
i learnt a lot from your post. thanks for your time and i hope to hear from u soon

It wont be 100% of the cause but will affect performance of the screen.

Yes, using a non-mains connected charger will be sufficient for the test, like your power bank for example

Note on images 4 and 5 you will see the copper shield, this model does not have the conductive cloth I mentioned but the copper ground plane can clearly be seen on both the body and screen. Fake and non oem parts tend not to have this, in the body there is also a copper area which can be removed by mistake on replacement of the screen.
this is not often found in the replacement screen kit.

if it's happening at another location then you can discount this theory.
I am still leaning towards incorrect parts or assembly as this is the cause I personally see most often and i've repaired a LOT of damaged phones. As you have stated you have more or less a complete new phone if they replaced screen+motherboard.
I once repaired a phone that had been back to the OEM service center, cause of fault was copper strip from old screen touching the board, the copper slip was so small i only noticed it when it sparkled under the right light, it's mistakes like that is what I am talking about, easily missed by many.

Sadly that can only be done by removing the screen. I dont suggest you try, ive seen the disassembly video, it's tough, one time job and if it goes wrong it's bye bye screen.

I sent in my phone to the samsung store to check the charging port (which is also making some problems), and i requested them to check the copper shield.
while i was there, i realised there is another phone which has the same problem as me. could it be that all the A5 model has the same problem ? :/

I don't think it's the phone model, we would see more reports if it was, I would enquire if the other unit also had screen changed. If it has then one might assume pirate parts, no way to prove that without checking back of lcd for the oem barcode sticker. The is on possibility I only just thought of, a while back I had a client bring me a i9505 that the oem changed screen on, I just reread the emails between us and the fix was replacing the screen with a i9505 screen, the oem locally only supplies i9500 devices so they only fitted a i9500 screen, turns out there is a difference in the touch chip, I was able to prove this by attaching the touch only circuit from his old screen. No more random touches.
From this I can assume the various SM-A500 models use different touch chips. Or slightly different firmware in the chip, I have seen that before on the rock chip based tablets I support here.

Battery issue
My galaxy A5 have some battery issue. It won't charge after 88%,and didn't turn off after 2%. The phone is turn on over night at 2%..please help me regarding this issue.
I just got done replacing my broken screen on my LG G3. I replaced the whole front panel and just transfered the guts. Everything checked out fine after replacement until i typed my first text message. row A-L will not goto screen unless I touch nearly inbetween the middle of the row beneath it. q-p work fine as well as z-m. What really has me boggled is that the screen accepts touches there in virtually every other app/drawing. Just the keyboards aren't allowing touch in that specfic row. any suggestion?
Found a few more bad section.. Pulled the back loudspeaker back out and tried reseating the cables and still had same issue. They're sending a replacement for free.
This was my first screen replacement, but not my first time dealing with small ribbon cables. All cameras function fine, hoping it was a defect in screen and not my screen changing abilities.. Any tips for the next one would be appreciated. Would like to have a fully functioning phone again sometime. This is nearly more frustrating than the broken screen.

Hey just curious if your issue has been resolved.... I am having same issue, but i took mine to a computer store i have been dealing with for years. about a year ago they started doing cell phone repairs as well. I had them replace my cracked screen on my LG G3 and that same row of text if off for me and there are a few other spots i have noticed are off as well .... very frustrating... Anyway the place I took it to has replaced 3 screens hoping they were getting defective parts.... they just called to tell me I can come get it but they were unable to repair the dead spots without going further into replacing boards or something.... I dont know... It is weird though cause you can get the dead spots to work sometimes by very lightly touching or just touching it in just the right spots like a calibration if off....

A review on G3 LCD's on Amazon reports the same problem "I installed the screen and immediately my wife mentioned that it seemed to have "dead spots" when she was texting / playing games. I noticed it myself when I tried texting myself as a test. Several of the letters on the keyboard just wouldn't register very well. She went into the settings and ran the "motion sensor calibration" test under general settings>gestures. This has resolved the touch screen issues. "
I don't see how that would fix it but I guess it's worth a shot.
