Waze got very heavy on system resources lately. Crashing extremely often. We had 3 relatively modern Android (>=4.4.2) phones on board and only on 1 waze could calculate route before it crashed. On this one phone that could at least calculate route Waze crashed when any warning on map was pressed or when you checked what is ahead of you (when more parts of map were loaded at once). Waze also froze my phone very often even when it was just navigating (nothing was pressed on screen when phone froze). It all looked like OOM and extreme overhead problems. Back in its days Waze was awesome, running on everything. But now Waze feels like alpha version. Also new UI is tragic, excess of useless. We are very sad that we have to look for alternative.

Not everyone have best-high-end golden phones, please keep it in mind when creating Waze. We could not send logs since it crashed too when button "send logs" was pressed.

Technical info:
All 3 phones had Android >= 4.4.2, from 512 to 1024 MB of RAM and we locked (disabled) all not needed apps (Messengers etc.) - it did not help much.
