So if you’ve cracked your screen on a brand, new Galaxy S4 and feel miserable perhaps because you don’t even have insurance, there’s actually a way to replace the screen glass only.
Now, for this to work, you must have a broken screen ONLY, if your digitizer is not working, this method will not work! To test this out, see if you notice any cracks in the digitizer layer under the glass layer. Also, check to see if your touchscreen is working. If you only notice cracks on the outer glass layer and also your touchscreen is working fine, you can use this method to replace the glass only and revive your Galaxy S4 for just about $20 USD.
