Replacing cracked front glass
Hello guys. Cracked my screen yesterday on my Sony Xperia z5. My LCD is just fine, touch screen is not working properly, proximity sensor also freaks out and of course the glass is cracked. I wonder can I replace only glass and touch panel something like that: https://www.amazon.com/Sony-Xperia-Digit.... Or I need to buy a full LCD replacement? Also I've seen replacement videos on youtube but I don't have a heater gun so can I somehow avoid this tool?
Is this a good question?
