I have purchased my mobile phone Moto G(4) in October 2016..
I was facing touch screen issue from last 2 months like...
sometimes touch screen is automatically seen pressed at a particular area "9 key of dialer".
it is also pertinent to mention that the problem was not permanent as i[censored] rubb two three times
after locking the screen it works good. but after some time or say locking or unlocking the phone many times the problem again arose.
so... in nutshell the problem purely related to touchscreen problem. no other issue at all...

so for this reason I visited the above said service center and they have deposited my phone for around 2 hour and after 2 hours the executive (lady) told me that your screen need to be replaced and as your phone is swatted you have to pay 5600 only as your phone is liquid damage... they have also given in writing to me (copy attached)...inspite of phone is still under guarantee...
Now the flash of the phone is not working and battery is not charging...
I think flash and battery has been replaced by above service center...
