about the screen then you may need to buy a new touchsurface for the device it can be removed and changed without changing the whole lcd
thnx
thanks for the adivices i will post some pictures..so i can't use the craddle because i don t have the connector from the bottom of the phone

think your best bet is to find out the part name / nr of the connector and buy a new one

if you ruin your touchscreen with having to calib it everytime you charge you batt it would be much more expensive
hi all since i bought my phone i got some serious problem which was the back button and menu button keeps vibrating when playing some games r browsing for 10 min it almost gets worst when u were using outdoor it vibrates more and cant use anymore so i just taken to service center and checked out they said some touch pad problem r may b screen
just yest i given it to service center but i think it cud b problem with screen bec when u hold the sensor it goes dark and u can clearly c the vibrating reduced so v have to live in bark place to get rid of this and one more thing if u lock the phone there was no vibration as well so it wont b problem with processor r mother board its just the screen r touch pad may b
and did anyone tried out turning off bravia engine?

i have a SE mini ST15i. i got same problem. Help please!
tks
I had my unit for two weeks now and so far i've never encountered this problem even though i've been playing a lot of games for more than 30 minutes.
What color and build number are your mini's? You check it out at the back of the unit after you've removed the battery.
mine is 11W31 Mini ST15i Black
Mine got the problem after 2 weeks, mine is 11W29 Mini ST15i Black
i got the same problem too... its really annoying... hope someone wud come out with a solution,,...
So, during the first two weeks your phone was working perfectly. And only after having it more than two weeks then the problem starts?
I had my unit 2 weeks and 2 days now. and have not encountered the back menu malfunction.
Yup i given back to service center and got back with in a day now i was testing it for 3 days since no problem so lets c how it goes later after some days
it may be the overheat problem..... after charging for a couple of hours it happens..
if u dont experience it,, u r lucky...
have a look at this link.. http://talk.sonyericsson.com/message/111285#111285
Since I bought the unit I've been charging it overnight before I sleep and so far it doesn't overheat. I've read it in the manual that it was alright to charge it as often as you like.
It seems that the build of the touch pad of this model is defective, just like with their unit the G900 which also had a lot of complaints.

Is there any solution to this problem? Today I flashed ICS and I felt that on charging or when headphones are connected the touch dont work properly. What should I do? Is there any update for this bug? kindly help. Or I should go back to GB.?

Please elaborate.....
What is this elebrate? bro touch is laggy. what elebration will do? for example while scrolling a page or switching between homescreens.
Actually, touchscreen lag often occurs when you connect the charger when the source of current is a bit flaky,ie, due to the loose flow of current, the normal touch sensors cant detect your fingers properly and make mistakes. I dont think its ICS here at fault and more likely the charger or the current source.
I have same problem after rooted.
my xperia st23i aka miro always wrong touch while charging, but no if i charging use pc.
I use official ICS rom.
Any solution please...

Charge voltage runs on the screen so you can't really touch. That problem is rare. What chargers did you guys use? Just let me know. Please use official charger

This problem usually occurs when you use a charger with a higher voltage or mAh. The screen actually becomes extra sensitive due to the way capactive touchscreen works. As such, your touches seem to turn random and uncontrollable. Using the charger that came with your phone would resolve this problem.

Well, I haven't been having this issue at all. Do you use any thirdparty charger? If so, try with the original one which came with the phone, sometimes thirdparty chargers and microusb cables can interfer with the touch.
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 have had touchscreen problems with my Honor 5X for the past two or three months.
When I am charging, random inputs will register all over the screen if I try to touch something on the screen. For example, if I were to swipe down from the top of the screen to open the notifications or change some settings, part of that swipe might register, but other random touches will register all over the screen, pressing the back button, home button, or anything else in the process. Swipe gestures are basically unusable most of the time while charging, and single, point touches work half the time.
However, this issue only occurs if I let it charge for a while with the screen off before unlocking the phone and doing whatever I need to do. This issue has occurred on multiple charging currents, from the 0.5 A provided by computers to 1.5 A from wall chargers. It also happens across multiple ROMs and clean reflashes -- on the stock latest EMUI Marshmallow ROM to all the builds of CM13 so far.
Has anyone else had this problem? If so, how did you solve it? I've had the phone for four or five months already, so I'm not sure if returning it is an option.

This sometimes occur when the cable you use is in a bad condition or when use your phone in a position that would bend the cable's connecter, have you tried changing the cable or the whole charger, try not to Bend the cable too, that's what's coming up to my mind as a first possibility.

Thanks for the replies. I have tried several different chargers including the OEM charger. This issue seems to happen at least half the time I charge the phone, which is disappointing as my Galaxy S4 never had such problems across all chargers that I have used.
Maybe I'll hold on to the phone for a while longer and see if the issue goes away. I haven't noticed it in the past day.

The only thing left to think about is the hardware, maybe you accidentally exposed the USB port to water or something, as the time passes moist begins forming, which damages the port, it could be due to water or high humidity, I'm afraid you'll have to change the port, but do check all the other possibilities before opting for this one, good luck.
try cleaning the port on the phone?
ur phone screen is original ? OEM Charger Never did this unless u have bad USB Cable or bad Elect. Source ! .
Have this too sometimes. Experienced it also before in my old phone while charging in USB. I think it has something to do with the electric current.
