Replacing the screen is way cheaper than buying a new phone.
Tips
usage
Colloquial contraction of 屏幕碎了 (the screen has shattered). Often framed as the subject-complement 屏碎了. Related set: 屏裂 (píngliè, cracked/split), 屏花 (pínghuā, screen distorted/garbled), 换屏 (huànpíng, to replace the screen).
register
Spoken and chat-common rather than formal. In a repair shop receipt you'd see 屏幕破损 or 触摸屏损坏. Android/iPhone users both use 屏碎.
