Samsung S6102 Duos - back button problem

Hi,
On my S6102 I've got a problem with back button: sometimes is unresponsive (does nothing when pressed) and sometimes is just laggy (responds after a while...).
That is very annoying, can anyone please help?
Many Thanks es!

Touch phones like ours have unresponsive touch keys because it isnt that sensitive like in apple products..and as long as lag is concerned it shouldnt be much... Try contacting service center if it persists any longer

I sent my phone to samsung service center. They said the less sensitivity of the return key may be caused by my screen protector. They asked me to remove it and tried for few more days.
Maybe you also can try it.

Oh i also try it ....... Thanks friend...

yes, the thickness of the screen protector affects the sensitivity..
my phone (S5360) has a quite thick screen protector and it makes the back and menu buttons dont work.. and then magically working again..
my friend has a thin one, and his buttons work well even its covered.
other tip: try cutting your screen protector to fit only the screen. so it dont block the back and menu button.

Confirm this is a problem with this device. Just purchased and without any screen protector there is a noticeable lag. or at times didnt work.
Changed to a new device after going to service center but the problem still persists.

its not responding due to lagging.

sometimes it just because of oil/dust accumulated on the back button screen area, happens on mine most of the time, just try cleaning your screen every now and then

I also have the same problem with mine, and it's been happening since the very first day, with and without screen protector. Looks like the button works best if you touch on its upper left side and not on the middle. Looks like a desing flaw to me.

I've added vibrate to back & menu button. It vibrate when you touch it. Now i know if it is responding or not.

I can also confirm lagging on back key. I just got my brand new (secondary) phone Galaxy Y Duos and I found this lag is annoying. Is there any solution available for this ?

in my opinion, this problem belong to hard ware

i ported techno duos custom rom to mine sgy and its much better than stock. more responsive and faster.

[Q] Dust on Galaxy S3 Camera Sensor?

Okay so ive had this issue for a few months now. I got my galaxy s3 over a year ago, and in around april, 2 black spots appeared when trying to take a photo or video with the camera. No i do not think it is a software issue because ive updated my phone, used 3rd party camera apps, and tried different ROMs. I also removed the lens cover with a pin and tried to clean it, but with no luck i also tried blowing on the camera, and still nothing. So i believe it is under the lens, on the sensor. Its really bothering me as I have OCD and I hate taking any pictures because of it. Yes i did research this issue, and it mostly happens to people when they first get the phone, and they return it. I do not have warranty as my phone is over a year old. If i still do have warranty, does rooting/flashing ROMs void the warranty? I have not tried to take it to Samsung, Best Buy, or AT&T because i was trying to find a solution without doing that, as they will probably charge me an arm and a leg for it.
Please help me.

Not sure if the lens is removable. ... you could see if you can get a cheap replacement camera on eBay and change it out. ...you could take it apart and try cleaning it more. As long as you use triangle away (if you have increased to counter) and flash a stock unrooted rom with stick recovery (there is a thread on this) they won't be able to tell you voided your Warrentee.

Sorry to hear that, same thing happened to me on my old phone. Got rid of most of it by unscrewing the back of the phone and blowing it with compressed air, but there was one stubborn spot I couldn't get rid of and I was out of warranty so I ended up just getting a new phone. If you do find a solution please post it to help others, as I have searched the internet and the only solution seems to be getting replaced under warranty. If you can do that it's probably your best option.

Another suggestion I heard is to try to dislodge the dust by tapping on the camera. It didn't work for me, but still worth a try.
Sent from my SGH-I747M using xda app-developers app

Me too
My friend is having this issue. We are currently trying the blowing technique and the tapping technique. Stop your dirty minds! I'm open to other solutions at this point though. My friend is getting royally screwed by the phone company right now. He has sent this phone in three times already and is ready to go nuts. Help a brother not go nuts please.

[Q] M919 Only Sync's To PC, But Doesn't Charge???

Hey guys,
Looks like I have a very unique problem here with my Galaxy S4, M919. I've had the phone for about 2 months and it's worked flawlessly until yesterday. It just randomly stopped charging!
I've replaced the charging port already and also re-flashed ROM (aokp_jfltetmo_kitkat_nightly_2014-03-27).
I am unable to charge the phone, however it syncs perfectly with my PC. I've searched all day yesterday and all morning today for anyone with a similar problem but have yet to find anything.
You guys are my best and only hope now.
Please..anyone. I really need your help! I can't afford to purchase a new device.
If you require more information, let me know.
Thanks in advance for your time and help!
EDIT
I just ordered a Qi Wireless Charger from eBay. I'm hoping it'll allow me to charge the phone since it completely bypassed the charging port and is located on the mobo itself. Will update once it arrives and I test it out.
Still looking for answers to this problem though. So if anyone has any thoughts on what may have happened (and its solution), it would be greatly appreciated!
EDIT 2
Just received the Qi Wireless Charger.. It does not work either =(
I will be flashing back to stock again and try to charge the phone while it is off. This is the last thing I can try now. If it still doesn't work, I will be parting out my phone.
LCD $180
MoBo $120
Remaining parts can be discussed
Just message if interested!

Have you attempted to flash another ROM and see if the problem persists? Another kernel? I suggest trying another kernel first, then another ROM. Also, I have to ask just to cover all bases, have you tried multiple ports on your PC? The device won't charge at all or just while connected to PC?

Hey. Thanks for the reply.
I've already tried flashing a new kernel as well as ROM. I've tried all 4 ports on my PC. I forgot to mention that it also does not charge through any wall adapters. Any charging method that involves using a Micro USB cable does not work. The only response I can get is data sync when attached to my PC.

If you are with T-Mobile, I sure hope you have insurance or JUMP. As a T-Mobile employee, I can vouch that this problem is considered a hardware defect and would fall under an insurance plan. The only thing is though, you'd you have to return to full uprooted stock as an employee in your store will have to perform a physical and software diagnosis. Physical is easy as long as the phone has no cracked screen, no water damage and is YOUR phone. Software, they will plug it into our diagnosis tool where we'd be able to see if you've installed ROMs and such, which would void your warranty.

Yeah. I've gone to stock..still doesn't charge. Re-rooted and flashed aokp again and same thing.
I honestly have no idea what could cause this. I've never..and i really mean never dropped my phone, nor had any sort of shock or damage to it. No liquid/moisture anywhere around it. No dust. It doesn't make sense for it to be something physical.. it's still being picked up by my computer. I'm still able to flash and transfer files to/from the phone. It just is not charging.

Well, it's most likely a malfunction then my friend. A customer came into my store just the other day with his S5 he just purchased three days prior. The device was stuck on that S-View screen even when the S-View case was not covering the screen and even completely detached. We tried everything you can at a T-Mobile store. Even factory reset. Still, the problem persisted. It happens friend, hope you have insurance or JUMP

Are you still having this issue?
I am having the same issue, but this only happens when installing a rom. You cannot just reflash the stock rom. If you still have to phone, I can give you a link on what to down load to set your phone back to defaults. Once you set it back to defaults you should be fine.
My issue:
I installed any custom rom and this Tmobile Phone will not charge at all!!!!
Complete set back to Tmobile Defaults charges perfectly.
I will try flashing a custom Kernel with battery management to see if this help.

Thanks for the reply. I ended up selling the phone to someone for a cheaper price. I tried to ODIN back to stock, however it didn't work. I'd still like to know why it would stop charging if a custom ROM was installed though.
Best of luck with your phone :good:

I found my issue, it first came by my root method. I was using a method that wasn't designed for my model. Then the issue was recovery, again wrong type for model. Finally I got everything to work and I lost lte. to fix that I just added the LTE profile and it works.

Got a LG G4 yesterday, having touch recognition issues.

Hey so I got an LG G4 yesterday and started noticing the screen not recognizing all of my touches, especially the double tap to wake and swiping from the edge of the screen. I have to tap twice very obviously, at a certain pace and deliberately hitting hard; otherwise it takes multiple tries to get it to work. Even then it's still not 100% accurate. I did get my first ever glass screen protector with it as the Telus employee recommended it so I'm not sure if it might be the cause? I don't want to peel it off as it was like $30 and if I peel it off and it still doesn't work I'm out $30 if I decide to return the phone.
I tried using an app someone recommended on here for changing the responsiveness of the screen to no avail. I also downloaded a touch testing app that definitely shows the missed touches all over the screen every few touches. I'm wondering if getting a replacement could solve my issue or should I be looking at choosing a different phone altogether?
Thanks!

Why did you bought it without testing the phone.. I did go to store and install every software i know and check everything then i got satisfied and bought the phone.

It seemed fine checking it in the store, I assume a product to work, not be cynical and assume there'd be issues. I also hadn't heard of the touchscreen issues as all the reviews I saw said it was awesome, period. I'm just trying to hear from people whether this could just be a lemon or is this really widespread?

Try to factory reset the phone..

I have been dealing with this problem for a few weeks ago. I also noted that I can't turn fm radio on. I reset my phone and now I also can't see the 9 dots icon with takes me to app list. I'm using stock rom I didn't install bootloader, scoff and none of these advanced stuff.

I have this same problem a few months, according to a person specialized in htc, all the devices of the one line are having serious problems of hardwere, where a part responsible for the signal power fails by oxidation of the solder causing the problem, becomes unviable The repair due to the risk of resolda of the plate cause a general failure in the device, the chances are 50% of success. The low chance of success is related to the type of solder used, being able to use the resolda to damage the plate of low thermal resistance. Sorry for the bad english of google.
