what happen to my iphone 4s???!!!!

i bought this iphone 4s long time ago. i don't think that it will cause me problem but now it cannot play song. but other than this the ringtone or the alarm even when making phone call is ok. just cannot play the song. if i use handfree everything good. but use the speaker no sound come out from the speaker. what should i do?? the home button has problem too. cannot function will but i know the home button usually will has problem. but the speaker. what happen ?? do you think that i should buy a new phone?? because this phone also many years ago. or just repair it?? 

i get my Oppo Find 7 with data plan. i signing up the telco package for 2 years. it just cost me about Rm600. so i not suggest you to buy a new phone at the store. it not so worth actually. if you sign up a telco package then you can get a new and good phone with a cheaper price. why not sign up a package??

hey i can recommend you a high spec and cheaper price phone. i know where you can get it. Celcom. celcom sometimes will do some nice and good promotion. with a cheap price you can get a high spec phone. nice right?? and now celcom is using 4GLTE. means that it is faster if compare with other telco that still using 3G. not just a cheaper price high tech phone and also fast speed internet. hahaha.

i think i will but iphone 6. because i saw a telco is doing a Hari Raya promotion. just less than Rm300 already can buy a brand new iphone 6. very worth although it need to sign up contract. where can get a new iphone 6 with Rm300. so i think it is worth lar. but which telco i already forget.
