Mobile phone memory card is good or bad, what is the impact of memory card on mobile phone?

Generally, there are dozens of cards on the market! TF card 1G more than 20 more 30 pieces! 4G of 40 more than 50 pieces!

8g of 98 pieces! Probably so ! If memory serves!

But there are many brands! Usually what you see is that the cards are in SanDisk or Kingston, but the phone is usually printed with Nokia ......This kind of thing, or not printed, not printed is called a whiteboard or a tabletop version! But these don't mean bad or bad quality!

Like mobile phones, cards also have parallel goods, refurbished! Brands have a brand fees and taxes! Refurbished we call washboard!

Second-hand to take back and then clean and then sell as a new one! In addition to refurbished and fake cards there are also upgrades! Whiteboard cards of this kind will not be bad!

Nowadays most people use this type of card! Even if it is Kingston's, **, 1g2g is only a few dozen yuan, but in specialty stores or shopping malls, this kind of will be sold for hundreds of yuan! Beg.

The quality of the brand's memory card is still better than that of the whiteboard. Read and write speed, defect rate, and a useful life. Memory cards are the same as **, there will be frequent ups and downs.

However, the brand's memory card will also be broken, but the probability of failure will be lower than that of the whiteboard. The memory card will be divided into C2 4 6, and the higher the value, the faster the write speed. Of course, the faster write speed will be slightly more expensive.

The requirements for write speed are not very high, so it's OK to buy a general one.

Disadvantages of memory expansion for phones:

The motherboard of the mobile phone is very precise, and the manual disassembly and modification of the memory chip may cause damage to the motherboard of the mobile phone, resulting in the scrapping of the mobile phone is not in the official maintenance channel to replace the product's noisy land parts, and the warranty service of the product will be lost, and the mobile phone operated by informal channels cannot guarantee the normal use in the future.

This operation itself may also bring hidden dangers in quality, manual operation can not ensure the accuracy is easy to cause virtual welding and welding empty, short-term use may not have a significant impact, but after long-term use, it is easy to cause crash, shortened battery life, motherboard leakage, etc.

It's not how much memory you run, you can use as much as you want, it's just a measure of the standard, the most in the use of the application, the highest can carry so many applications at the same time at the runtime, but not every moment can reach this peak, the phone will allocate itself during the runtime, as long as the allocation is reasonable, maintain normal use.

There will be no jamming if there is no serious imbalance, but many mobile phones can not be reached, it also depends on how the system of the mobile phone is, if the system type is good, reasonable allocation, you can achieve good results, but if the system is not good, then no matter how much running memory, the allocation is not good, it will still be stuck.
