Some months ago I installed an Android 4.2.2 ROM on my phone and it worked fine for a few days, then the phone started getting too slow and laggy. I made a factory reset many times and I tried installing different versions of the ROM (from different countries), but the same happened. I went back to 4.1.2 and I have the same issue. After the factory reset, my phone is fast, but I start installing apps and it gets really slow. I have noticed that when I stop "Google play services" it gets faster again for a few minutes/hours.
I have tried many things that I have read and in other forums.
I deactivated the gallery app and many of the apps that come with the phone. I cleaned the cache data, etc.
What can I do?
Thanks in advance
EDIT: I ran SD Card Tester to check the writing speed of the internal storage and it gets stuck after writing around 150 mb and the writing speed drops to 0.89 mb/s and the phone gets extremely slow. I had to close everything.
