Mediatek with Model Code "65XX" Common Problems

Mediatek chipset with model code 65XX is near to bottleneck because almost all current smartphone is not using this chipset anymore. Some budget and beginner level smart phone may still apply this chipset. The main reason is Mediatek is replaced the newer processor with model code start with "67XX". The still using 65XX chipset is "MTK6580". I still see new coming smart in very low budget and price using this. 

I have experienced with smartphone with Mediatek "65XX". There are few common problems occurred. First, I have very low output sound either on 3.5mm earphone plug or internal speaker. Of course, some developer may apply external sound chip to out perform better output sound, but does it make sense to increase cost. Rather than developer can choose better chipset of a bit higher in cost.

The GPS module of Mediatek can say it is working nor not. The GPS signal is too weak until get accuracy within 10 meter. It is 10 meter, can not imagine how you navigate your journal when your car show on the building on the navigation app. Obviously,  the possible locked satellites on my tested phone is around maximum is 7. Understand that locked 3 satellites is workable GPS, but I need more locked satellites in case of the car moves into some blind spot is too weak to received the GPS signal. At least, there is more optional choices to locked other satellites easily.

Why Mediatek is used to choose to multiple the processor cores only within Cortex-A7 for more advance model 65XX? In some old school chipset may use Cortex-A9, especially the MTK6575 and MTK6577. The bigger brother in this field, Qualcomm is using Cortex-A17 more powerful core for the performance. In that century, still happened some other chipset maker such as Ericsson, Texas Instruments, and Broadcom in the game. They are using Cortex-A7 for more cores processor.

Something is hidden from user - Cache memory. Cache memory is important to store commands to execute by processor in queue of task. Mediatek is cut of the Cache memory size in the technical specification. There is not so obvious normal user can realize this problem. Other chipset competitor may not cut cost in this.
