Guys... I m using Samsung A71 8gb 128 whenever I plays music on mobile or on youtube on  full volume it automatically slows after 30 or 50 seconds. Ikindly help with this shit. I want to know if the  problem is with my mobile or any software issue. Plz gelp me with it. Also, I ve not updated to the latest android 3.1 yet.

Agar continuously full volume per phone use keroo **bleep** to speaker garam hona start ho jata ha or jal sakta ha.
Is say bachnay kay liya volume kaam honay lag jata ha takay speaker ma koi issue na ai

Aapki baat theek hai pr 30 seconds ka baad hi band hona ajeeb chez hai...aur sound slow itna hojata hai k bnda youtube pa video aram sa smjh ni pata

Ap ka speaker kharab ho gya ho ga. Local speakers RS 20 to RS 50 kay mill jatay han bahir say whole sale rate per. I recommend you to visit ssung center and change speaker because your speaker coil is damage and heat up after 30 sec
