The OnePlus One is the one of the best phones I have owned. It can easily get me through a day with moderate usage. The phone rarely stutters or slows down even when multitasking more than 20 apps open at a time. The multi-touch issues were noticeable more when I first got the device than later on in its usage. However, I have refused to update beyond firmware 25R as it appears to be the most stable of the lot.
I have used this phone for 2 years and it has become a reliable friend to me. However, the battery is exhibiting signs of old age as occasionally it will die around 20%. A reboot will readjust the numbers and it will then display the correct percentage, but this has never happened before so I know it’s a sign of age and gradual death. Because of this I was forced to purchase a new phone and I will use the OnePlus One as a back up.
