Speaker me awaj nhi athe acha sahe

@rohaansharma you are not giving us a lot of information about what you have already checked. We will assume you made sure that all the settings are okay and that you have connected a headset to see if that has sound and if the volume up and down works with the headphone as well.

If that is correct then the issue is most like a bad speaker. Since iFixit does not yet have any specific guides for that, use the ones from here right up to step 10. The instructions are in English so use a browser that can do the translation for you, if needed.

Replacement speakers are readily available.

@rohaansharm aapane jo pahale hee jaanch liya hai, usake baare mein aap hamen zyaada jaanakaaree nahin de rahe hain. ham maan lenge ki aapane sabhee setings theek se kar lee hain aur aapane ek hedaset kanekt kar liya hai taaki dekh saken ki usamen aavaaz aa rahee hai ya nahin aur volyoom badhaane aur ghataane kee suvidha hedafon ke saath bhee kaam karatee hai ya nahin.

agar yah sahee hai, to samasya kharaab speekar kee hai. choonki ifixit ke paas abhee tak isake lie koee vishisht gaid nahin hai, isalie charan 10 tak yahaan se die gae nirdeshon ka istemaal karen. nirdesh angrezee mein hain, isalie zaroorat padane par kisee aise brauzar ka istemaal karen jo aapake lie anuvaad kar sake.

riplesament speekar aasaanee se upalabdh hain.
