On the market we have a huge selection of smartphones at various price shelves. Simply put, everyone will find something for themselves. However, there are devices that you will regret buying. Distinguishing them is quite simple, just look at the specification and possibly find some details on the network. It is worth looking earlier than regretting the purchase. The operational memory is responsible for storing open applications (including the system itself) and quick sharing of collected data with the processor. In the case of cheap phones, we are only interested in its capacity. Today, we will no longer meet phones with only 512 MB RAM, although exceptions do occur, I categorically advise against them in the case of used devices. The most popular value is 1 GB RAM and this is not a good solution. Android is able to work properly with such parameters, but the use of additional applications (especially social) can be a chore. Admittedly, only slim Android Go can be installed there, but the software in this case is not able to compensate for weak hardware. For this reason, it is worth investing in a phone with 2 GB RAM. More memory is definitely worth the price. The second very important component is of course the processor. He processes the data so that the phone carries out our commands. For the average user, determining the actual performance of the mounted system can be quite difficult. Stores and supermarkets in promotional leaflets and media usually provide information on the number of processor cores or timing. These parameters are completely useless. In the case of cheap smartphones, we should be interested in information about the processor cores used. The bottom shelf is dominated by phones with MediaTek chips, sometimes you can also hit Unisoc (Spreadtrum). These companies use already existing and commonly known cores in their processors. In the price shelf up to PLN 300-400 we can find smartphones with processors based on Cortex-A7 and Cortex-A53 cores. The difference in performance is colossal in favor of the A53 cores. The Cortex-A7 core was presented in 2011, it was a pretty decent layout in the past, but today it can't cope with modern software. Unfortunately, such systems are still being produced for extremely low-end smartphones.
So witch phone is the cheapest smartphone good for use in 2020?
Receiving information about the cores used may be a problem. Shops usually do not inform about the type of processor cores, often they are missing even in the official specifications. There are two possibilities in this case. Being in a stationary store, we can ask one of the employees about it, theoretically, he should be able to answer. Of course, only theoretically, because large stores often employ people without any knowledge of modern technology. Let's ask and find out. The second way is the official specifications. The manufacturer must provide at least a model of the mounted processor, and with this information we can look for the specification of the processor itself, where there will be information about the cores. As an example of a processor with Cortex-A7 cores, we can mention the MediaTek MT6580 chip. The phone is built of many components, but most of them do not affect performance. We also have to reckon with the fact that when looking for savings, the manufacturer will have to use weaker components. For this reason, we do not expect a good camera and display in the phone for PLN 300. On the other hand, it is better to buy a phone with a weaker display than one that due to low performance will not be usable. Despite everything, you can find cheap and reasonably equipped smartphones, the choice is huge. For my part, I can only advise against cheap phones from Aliexpress, because in their case we are really buying a pig in a poke. It is better to buy the phone in person, even if it is to be cheaper. A nice addition for cheap phones can be slim Android Go, which will soon be installed on all devices up to 2 GB RAM. However, it should be remembered that Android Go probably means restrictions, we can have a problem with the proper functioning of smart watches. In this version of the system it is completely impossible to pair the watch with Wear OS.
