yes if you are getting ghost touches, you should return it.  It is only going to get worse over ti ...

Oops, I don't know where did you get that info from. In fact the opposite is the truth.
: the touch panel should be perfectly insulated from the ground. Probably a gap of the insulation disturbs the electric field generated by the capacitive surface of the touch panel.

I repeat: the problem is less worse then what I have seen on youtube. Is sporadic and basicly accetable.
After all, I have two years warranty and, if the problem increases, I can return the phone when i want.

I have the same ghost problems on my emax. It is really annoying typing the sms. The only solution is to turn it around on horizontal keyboard, but still with problems that could be little bit corrected with a spell checher. I tried to solve this problem out to find the path of the apperiance, but I couldn't so the best name is ghost typing problem. I do not what to do. Should I return it to the Banggood or use it as it goes. Shame for UMI that they have shiped a phone with such a problem!

This is a sporadic issue but it seems, quite a lot of devices are affected. You shouldn't use your phone as is, of course. Unfortunately I've never get an eMAX with this problem to be able to discover the source of this issue. My own phone works perfectly from the beginning. In your case you should send back your stuff for a replacement.

Just expect support from others .. can UMI some one suggest.............to satisfy the people whoe suffer with ghost issue (in their phone ) problem....

As I mentioned, I was not able to discover the source of this issue, but (according to my several years experience) I guess this problem is not caused by the defection of the touch panel itself but by a bad assembling. So in fact, to replace the whole screen is not needed, just a proper insulation should be applied. Of course, without looking inside a such phone I just guess.

Is this problem related with the double tap function?

Edited by nveronski at 2015-10-13 16:01 \n\nHi, this is ongoing issue for me since i bought Emax.
Love the phone just because it lasts allmost full two days for me with regular use (i love it)

BUT!
the "Ghost Touch" is still there after few advises from this thread.
Did Factory Defaults (twise) resolved for few days.
Opened the back cover to check is the LCD+Touch panel connector are tight.
Tried other ROMs from Rootjoy, didn't stayed long until rolled back to "Original"

The last thing i'm planing is to replace the LCD+Digityzer completely
will this help, is this an issue with defective Touch panel ?

Yes, this issue is still might be caused by the defection of the touch panel and unfortunately that cannot be replaced separately. On the other hand, this is definitely covered by seller's warranty, so they should solve this problem by their own.
