Resposta para "iPhone 4 proximity sensor not working after replacing BLACK GSM"okay well, i have an iPhone 4 with sprint. i have had it for not that long. i dropped it once before and it cracked once in two places. ever since then on one corner (at the top of the phone) some pieces of the glass have been coming off and it had a minor twitching. the other day i dropped it in my kitchen and it cracked again.. this time something is all messed up..idk what it is, but it doesnt do anything when i touch it, like when i try to side open open the front lock screen it doesnt do it.. it juss stays still.. is there anything i can do to fix it or is it time to get a new phone???
