my phone fell down once after 5-6 months the touch gets hanged, while incoming calls and using the phone.After that i changed the screen and everything went well,after nearly one month same problem comes back is it the problem of the screen or the logic board
Hard to tell without measuring and without divination powers. One month is a pretty long time for a board issue though.. we couldn’t rule it out completely but in this case I’d be more inclined to think about a faulty screen and I’d go for a replacement to start with, since it’s relatively inexpensive and easy.
